Answer:
x = 15
Step-by-step explanation:
x + 2y = 37
x - y = 4
x + 2y = 37
2x - 2y = 8
3x = 45
x = 15
Steps:
1. Isolate y in the equation x - y = 4
x - y = 4
-y = 4 - x
y = 4 - x / -1
2. Substitute value of x (15) into the new equation y = 4 - x / -1
y = 4 - 15 / -1
y = -11 / -1
y = 11
3. Plug in your y value (11) and x value (15) into the equation x + 2y = 37
15 + 2(11) = 37
15 + 22 = 37
37 = 37 ✅
4. Plug in your y value (11) and x value (15) into the equation x - y = 4
15 - 11 = 4
4 = 4 ✅
both equations are true with the value of x being 15 therefore your answer is
(4) x = 15

What is the
range of the function graphed below? ((Writing the answers in case you can’t read them well))
A. -infinity < y < 2
B. -2 < y < infinity
C. -infinity < y < -2
D. -infinity < y < infinity
Answers
Given:
The graph of a function.
To find:
The range of the graphed function.
Solution:
We know that, the domain is the set of x-values and range is the set of y-values values.
From the given graph it is clear that the functions is defined for all real values of x.
[tex]f(x)\to -\infty\text{ as }x\to -\infty[/tex]
[tex]f(x)\to 2\text{ as }x\to \infty[/tex]
The values of the function lie in the interval [tex]-\infty<y<2[/tex].
Range of the function [tex]=-\infty<y<2[/tex]
Therefore, the range of the graphed function is [tex]-\infty<y<2[/tex] and the correct option is A.
Divide f(x) by d(x), and write a summary statement in polynomial form and fraction form. F(x)=x^2-12x+43;\ d(x)=x-6
Answers
Answer:
Quotient: x^(2)-6
Reminder: 7
Step-by-step explanation:
See the attached image.
The Polynomial form of F(x) / d(x) is (x - 6) + 7 / (x - 6).
What is division?It is the basic arithmetic operation, in which you are separating the number into some parts.
Given:
F(x) = x² - 12x +43
d(x) = x - 6
Then,
F(x) / d(x) = x² - 12x +43 / x - 6
Factorize the numerator,
F(x) / d(x) = [(x - 6) (x - 6) + 7] / (x - 6)
F(x) / d(x) = (x - 6) (x - 6) / (x - 6) + 7 / (x - 6)
F(x) / d(x) = (x - 6) + 7 / (x - 6),
Therefore, the Polynomial form of F(x) / d(x) is (x - 6) + 7 / (x - 6).

Step-by-step explanation:
The value of x will be x = -15/2
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that the equation – 2/3X – 1 = 4
Here, we need to solve for x,
– 2/3X – 1 = 4
Now combine the like terms;
– 2/3X = 4 + 1
-2/3x = 5
x = -15/2
Therefore, the solution will be as;
x = -15/2
The value of x will be; x = -15/2

Martin and Eric are preparing to board a roller coaster together and pick their seats. Martin selects a seat first, and then Eric selects one from the available seats.
Are these two events dependent or independent? Justify the answer.
Answers
Answer:
independent
Step-by-step explanation:
The two events are independent because the seat that Martin selects does not affect the seats that are left for Eric to pick.
What Are Independent Events?An Independent Event is defined as if the outcome of one event has no bearing on the outcome of the other, the two events are said to be independent events. Or, we may say that an event is considered independent if it does not affect the probability of another event. Probability-independent events mirror actual occurrences.
Martin and Eric choose their seats as they get ready to ride a roller coaster together. Eric chooses a seat from the various options after Martin does.
Because Martin's choice of seat has no impact on the seats that Eric has left to choose from, the two events are independent of one another.
Hence, the two events are independent because the seat that Martin selects does not affect the seats that are left for Eric to pick.

download mathaway and put the equations in it and press graph
Answer:
Step-by-step explanation:
To graph the lines you only need to connect two points and extend the line in either direction as far as you wish.
The first line is y=x-1
We get two points by subbing in any two values of x
y(0)=0-1=-1 and y(1)=1-1=0
So you just connect (0,-1) and (1,0)
The second line is y=-x/3+3 and we can do the same thing
y(0)=-0/3+3=3 and y(3)=-3/3+3=2
So you connect (0,3) and (3,2)
