D. Carbon dioxide increased, leading to more energy in the Earth system and more energy absorbed by Earth’s surface.
Answers
Answer:
Step-by-step explanation:
ore energy entered the Earth system than exited due to the greenhouse effect, solar energy trapping systems like solar panel, etc.
How CO₂ changed the energy in the Earth system due to many reasons:-
Carbon dioxide forces the Earth's energy budget out of balance by absorbing thermal infrared energy radiated by the surface. It absorbs thermal infrared energy with wavelengths in a part of the energy spectrum that other gases, such as water vapor, co₂, etc.
The greenhouse effect also increases energy in the earth's system.
An increase in the amount of carbon dioxide creates an overabundance of greenhouse gases that trap additional heat.
These greenhouse gas emissions have increased the greenhouse effect and caused the earth's surface temperature to rise.

Find the nth term of this number sequence
1, 7, 13, 19, ...
Answers
Answer:
6n-5
Step-by-step explanation:
Some different types of sequences
To find sequence patterns, often the sequences are arithmetic (adding by a constant amount) or geometric (multiplying by a constant amount).
To test if something is a geometric sequence, find the quotient of (divide) adjacent terms.
To test if something is an arithmetic sequence, find the difference of (subtract) adjacent terms.
Finding the type of our sequence
Note the following:
19-13=6
13-7=6
7-1=6
So, to get each next term, add 6. However, what is the nth term?
Finding an expression for our sequence
You'll be adding up "n" sixes to get there (expressed with multiplication, because multiplication is shorthand for repeated addition), but we need a starting point so that when n=1, the expression equals 1, and when n=2, the expression equals 7... and so on. This starting point shifts the "6n" piece of our expression so that it lines up on the sequence. I'm going to call this starting point "b" for the base that is supporting this sequence.
So the expression will look something like [tex]6n+b[/tex]
Knowing that the expression needs to equal 1 when n=1, we can set up an equation and solve for "b".
[tex]6n+b=n^{\text{th}} \text{ term}\\6(1)+b=(1)\\6+b=1\\(6+b)-6=(1)-6\\b=-5[/tex]
So, the expression for the nth term of the sequence is [tex]6n-5[/tex]
Verifying
To verify that the expression we found is right, we can test our expression for each of the terms we do know:
The first term (n=1) is 1
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]
[tex]6(1)-5 \overset{?}{=} (1)[/tex]
[tex]6-5 \overset{?}{=} 1[/tex]
[tex]1 \overset{\checkmark}{=} 1[/tex]
The second term (n=2) is 7
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]
[tex]6(2)-5 \overset{?}{=} (7)[/tex]
[tex]12-5 \overset{?}{=} 7[/tex]
[tex]7 \overset{\checkmark}{=} 7[/tex]
The third term (n=3) is 13
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]
[tex]6(3)-5 \overset{?}{=} (13)[/tex]
[tex]18-5 \overset{?}{=} 13[/tex]
[tex]13 \overset{\checkmark}{=} 13[/tex]
The fourth term (n=4) is 19
[tex]6n+b=n^{\text{th}} \text{ term}\\[/tex]
[tex]6(4)-5 \overset{?}{=} (19)[/tex]
[tex]24-5 \overset{?}{=} 19[/tex]
[tex]19 \overset{\checkmark}{=} 19[/tex]

Answers
Answer:
The answer is incorrect because the slope formula was used incorrectly in step 1 (parentheses weren't used during the substitution and/or the wrong values were substituted).
y=4x-6
Step-by-step explanation:
The equation we're looking for in slope intercept form looks like [tex]y=mx+b[/tex], where "m" is the slope, "b" is the y-coordinate of the y-intercept, and "x" and "y" are variables that have a certain mathematical relationship through this equation.
To find the equation itself, it usually is easier to find slope before finding the y-intercept.
Finding the slopeThere are many ways to represent slope (usually represented by the letter m), and while they all mean the same thing, they look different, some examples are shown below:
[tex]m=\frac{rise}{run} =\frac{\text{horizontal change}}{\text{vertical change}}=\frac{\Delta{y}}{\Delta{x}} =\frac{\text{change in }y}{\text{change in }x}=\frac{y_2-y_1}{x_2-x_1}[/tex]
For this problem, since we are given ordered pairs, probably the most useful version will be the last one:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Substituting the values from the ordered pairs, it's important to remember that the ordered pairs are (x,y)... that the first coordinate is an x (and will go into the denominator, or bottom, of the fraction), and the second coordinate is a y (and will go into the numerator, or top of the fraction).
It actually doesn't matter which point we choose to be point 1, and which point we choose to be point 2. For the least amount of confusion, I choose the first point they gave to be point 1, and the second point they gave to be point 2.
So, [tex]\text{Point 1: } (1,-2)[/tex], and [tex]\text{Point 2: } (3,6)[/tex]
If I could give only one piece of advice, it would be "ANY time you substitute, use parentheses." You can always simplify later, but for the initial substitution, keep them (this is why the "mistake" happened in this problem, and is the thing we need to fix).
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{(6)-(-2)}{(3)-(1)}[/tex]
Simplifying...
[tex]m=\frac{(6)+(2)}{(3)-(1)}[/tex]
[tex]m=\frac{8}{2}[/tex]
[tex]m=4[/tex]
Thus, the equation we want in slope intercept form, with the new information we know plugged in, looks like this:
[tex]y=(4)x+b\\y=4x+b[/tex]
"b" is still the y-coordinate of the y-intercept (which we don't know yet), and "x" and "y" are variables related through this mathematical equation.
Finding the y-interceptWith "m" solved for, we can solve for the "b" by using the relationship in the equation we have so far.
We know that every "x" and "y" ordered pair is an "x" related to the "y" by this specific equation. Even though we don't know the specific value of "b", we know that the equation must be true for every ordered pair on the line.
While we don't know many associated "y" values and "x" values (for instance, we don't know what the "y" value is when the x is 10, and we don't know what the x value is the "y" is 26), we do know two associations for sure... from the two ordered pairs
[tex]\text{Point 1: } (1,-2)[/tex], and [tex]\text{Point 2: } (3,6)[/tex], so
[tex]x=1 \text{ is related to } y=-2[/tex], and [tex]x=3 \text{ is related to } y=6[/tex]
... and they're related through this equation that we've almost found!
Now, in our equation, there is only room to associate one x and y value at a time, so we need to pick one known association, and substitute those values in. Since this equation is supposed to relate the x to the y, it should be true for both points (so, we can try both, and it should work out the same. If you don't want to try both, if you see one ordered pair that has numbers that look easier, use that one):
Substituting Point 1 to find b
[tex]y=4x+b[/tex]
[tex](-2)=4(1)+b[/tex]
simplifying the right side, 4*1 is 4...
[tex](-2)=4+b[/tex]
subtracting 4 from both sides of the equation, and simplifying the left hand side
[tex]-2-4=b\\-2+-4=b\\-6=b[/tex]
Substituting Point 2 to find b (not necessary, but a good double-check)
[tex]y=4x+b[/tex]
[tex](6)=4(3)+b[/tex]
simplifying the right side, 4*3 is 12...
[tex]6=12+b[/tex]
subtracting 4 from both sides of the equation, and simplifying the left hand side
[tex]6=12+b\\6-12=b\\6+-12=b\\-6=b[/tex]
So, as a verification, we get the same value of b (which we should have, because this equation is supposed to work for every pair of (x,y) that has this relationship, and those were the only two points that we knew that did).
The Final equation in slope intercept formSubstituting the value we found for b:
[tex]y=4x+(-6)[/tex]
...and simplifying...
[tex]y=4x-6[/tex]
Find the constant of variation for the relation and use it to write an equation for the statement. Then solve the equation.

D)City À was 5° C, and City 3 was -5° C.
Answers
Answer:
A) City A was 5°C and City B was 4°C
Step-by-step explanation:
let temperature of City A be x and City B be y
According to the conditions of the question
4x = 8 + 3y (first temperature)
x - 2y = -3 (second temperature)
x = -3 + 2y
4(x) = (-3 + 2y)×4
4x = -12 + 8y
But it's already given that 4x = 8 + 3y
So,
8 + 3y = -12 + 8y
8 + 12 = 8y - 3y
20 = 5y
y = 20/5
y = 4
That means City B temperature was 4°C

Answer: 45
Step-by-step explanation: I used a graphing calculator and input all the equations and all the restraints, and I found that you can’t use the first equation since x has to be less than or equal to -3, and the question calls for x to be -2. So, in the second equation, there’s a point (-2, 16) and in the third equation there’s a point (1, -3). You know you have to use these two points since in the second equation, the restraint only lets you use numbers greater than -3 or less than 0, which cannot be one, and in the third equation, the restraint only lets you use numbers greater than 0, which can’t be -2. I hope that made some sense. So then, with substitution the equation would be 3(16)+(-3) which equals 45. 3(16)=48. 48-3+=45

The solution for the given equation will be x=7.8873 and x=0.112699.
What is a quadratic equation?The polynomial having a degree of two or the maximum power of the variable in a polynomial will be 2 is defined as the quadratic equation and it will cut two intercepts on the graph at the x-axis.
Find the Solution for
9x²−72x+8=0
using the Quadratic Formula where
a = 9, b = -72, and c = 8
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
[tex]x=\dfrac{(-72)\pm\sqrt{(-72)^2-4(9)(8)}}{2(9)}[/tex]
x= [tex]\dfrac{72\pm4896}{\sqrt{18}}[/tex]
The discriminant b2−4ac>0
so, there are two real roots. After solving for plus and then minus we will get two values as follows.
x=7.8873
x=0.112699
Therefore the solution for the given equation will be x=7.8873 and x=0.112699.
