Answer:
Step-by-step explanation:
B) it is increasing, the slope of 2/3 tells you it's going up
Using concepts of linear functions, it is found that the correct option is given by:
B) It is increasing.
--------------------
The equation of a linear function has the following format:
[tex]y = mx + b[/tex]
In which m is the slope, being the value that describes its behavior.
If m = 0, the function is constant.If m > 0, the function is increasing.If m < 0, the function is decreasing.--------------------
In this question, the equation of the line is:
[tex]f(x) = \frac{2}{3}x - 2[/tex]
The slope is [tex]m = \frac{2}{3}[/tex], which is positive, thus the function is increasing, and the correct option is B.

Answer:
68°
Step-by-step explanation:
The sum of all internal angles of a circle always total 360°.
So, we can add the three angles (ADB, BDC, ADC) and equate them to 360°.
90 + (2x+1) + (2x-3) = 360
90 + 4x -2 = 360
4x - 2 = 360 - 90
4x - 2 = 270
4x = 272
x = 272/4
x = 68°
From here, you can find any of the two unknown angles by simply plugging in x = 68°.

Given: ⅓ (18x + 27) = 81 Prove: x = 12
Answer:
Firstly, rewrite the equation:
⅓ (18 + 27) = 81
Substitute x for the given number of it's supposed equivalent.
In this case x = 12.
⅓ (18(12) + 27) = 81
Solve using PEMDAS and simplify what is in the parenthesis first. Then, multiply.
(18 x 12) + 27 = 243
Now, solving using PEMDAS, multiply the total of what you got that was originally in the parenthesis by ⅓ .
⅓ (243) = 81
When you multiple these number they are equivalent to 81.
81 = 81
Since the equation given, when substituted x for 12, is equivalent to 81, this proves that substituting x for 12 makes this equation true.

The area of triangle is 72.62 square meters.
What is a triangle?A triangle is a flat geometric figure that has three sides and three angles. The sum of the interior angles of a triangle is equal to 180°. The exterior angles sum up to 360°.
For the given situation,
The sides of triangle are
a = 20 meters, b = 10 meters, c = 15 meters
The formula of area of triangle is
[tex]A=\sqrt{s(s-a)(s-b)(s-c)}[/tex], where
[tex]s=\frac{a+b+c}{2}[/tex]
Now, calculate s as
[tex]s=\frac{20+10+15}{2}[/tex]
⇒ [tex]s=\frac{45}{2}[/tex]
⇒ [tex]s=22.5[/tex]
Thus area of triangle is
⇒ [tex]A=\sqrt{22.5(22.5-20)(22.5-10)(22.5-15)}[/tex]
⇒ [tex]A=\sqrt{22.5(2.5)(-12.5)(-7.5)}[/tex]
⇒ [tex]A=\sqrt{5273.4375}[/tex]
⇒ [tex]A=72.618[/tex] ≈ [tex]72.62[/tex]
Hence we can conclude that the area of triangle is 72.62 square meters.

Each box contains 4 toys; a 5-ounce truck and three bags of marbles. The bags of marbles are all identical. How much does each bag of marbles weigh
Answer:
15 ounces
Step-by-step explanation:
Each box contains 4 toys; a 5-ounce truck and three bags of marbles. The bags of marbles are all identical. How much does each bag of marbles weigh?
We need the total weight of the box. This is not given in the question, hence:
Let us assume
The total weight of the = 50 ounces
A 5-ounce truck and three bags of marbles.
Let the weight of one bag of marble = x
Hence,
5 ounces +3x = 50 ounces
3x = 50 ounces - 5 ounces
3x = 45 ounces
x = 45 ounces/3
x = 15 ounces
Therefore, the weight of each bag of marble is 15 ounces

Here is how Noah solved his math problem. Do you agree with his method?
Explain why or why not.
Noah's method:
add 9 to each side
2(x - 9) = 10
2(x-9)+9 = 10 + 9
2x = 19
2x - 2 = 19-2
19
2
divide each side by 2
X=
No, because he kept adding to both sides rather than distributing 2 from x and 9 from the start
Answer:
I don't agree with his method because he should've used the distribute method for the first step. For step 2, he would've needed to add 18 on both sides. Step 3 would be for him to divide both sides by 2, not subtract 2.
Step-by-step explanation:
2(x - 9) = 10
step one: distribute
⇒ 2x - 18 = 10
step two: add 18 on both sides and then simplify
⇒ 2x - 18 + 18 = 10 + 18
⇒ 2x = 28
step three: divide both sides by 2
⇒ [tex]\frac{2x}{2} = \frac{28}{2}[/tex]
⇒ x = 14

For what values of t can 2x^2+tx+10 be written as the product of two binomials?
The value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.
What is binomial?A binomial expression is an expression that has two terms.
In order to get the value of t for which the given expression 2x²+tx+10 will be a product of two binomial. We need to find a number(A) that is when broken into two other numbers(B and C), the sum of these numbers(B and C) is the number itself(A). Also, the product of the two numbers is equal to the product of the rest two terms of the expression(2 and 10).
Therefore, the number that fulfills this condition is 9. Let's check by substituting the value of t as 9.
[tex]2x^2+tx+10\\\\= 2x^2+9x+10 \\\\= 2x^2+5x+4x+10\\\\ = x(2x + 5)+2(2x+5)\\\\= (x+2)(2x+5)[/tex]
Hence, the value of t for which the given expression 2x²+tx+10 will be a product of two binomial is 9.

A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?
Given:
A triangle has side lengths of (6p – 7) centimeters, (7p – 2) centimeters,
and (6q – 9) centimeters.
To find:
The expression that represents the perimeter, in centimeters, of the triangle.
Solution:
We know that, perimeter of a triangle is the sum of its all sides.
[tex]Perimeter=(6p-7)+(7p-2)+(6q-9)[/tex]
Combining like terms, we get
[tex]Perimeter=(6p+7p)+6q+(-7-2-9)[/tex]
[tex]Perimeter=(13p)+6q+(-18)[/tex]
[tex]Perimeter=13p+6q-18[/tex]
Therefore, the perimeter of the triangle is represented by the expression [tex]13p+6q-18[/tex] centimeters.
