Answer:
a = 51 , b = - 7
Step-by-step explanation:
Expand and simplify left side , then compare like terms on both sides.
4(9x + 11) + 5(3x + b) ← distribute parenthesis
= 36x + 44 + 15x + 5b ← collect like terms
= 51x + 5b + 44
Compare terms with right side ax + 9
Compare x - terms
51x and ax
For these terms to be equal then
a = 51
Compare constant terms
5b + 44 and 9
For these terms to be equal , then
5b + 44 = 9 ( subtract 44 from both sides )
5b = - 35 ( divide both sides by 5 )
b = - 7

What is a proportional relationship?
A proportional relationship is:
y = k*x
Where k is the constant of proportionality.
So, a proportional relationship is a linear equation that passes through the point (0, 0).
With that in mind, we can see that the two graphs that represent a proportional relationship are A and C.

Answer:
The slope of the fuction is going downwards left. (coordinate plane)
Step-by-step explanation:
It's going downwards left on a coordinate plane because it's going from positives into negatives.
Answer:
The slope is -7/4
Step-by-step explanation:
For every 4 to the right, it goes down by 7. So rise over run so the rise is -7 and the run is 4 so that gets us -7/4

Answer:
Exponential
Step-by-step explanation:
- Linear is a straight line no matter what.
- Quadratic lines makes a u or v shape that opens up, down, left, or right.
- Exponential is like a slanted 45° clockwise u and a bit stretched horizontally.
- Square root lines on a graph, looks more like a slanted L 90° clockwise.
- Inverse Variation would show its inverse, same as a mirror, it would be something similar to a hyperbola.

The senior class at High School Arented and filled 9 vans and 7 buses with 457 students. High School B rented and filled 11vansand 7 buses with 473 students. Each van and each bus carried the same number of students. How many students can a van carry? How many students can a bus carry? A) Van: 55, Bus: 8 B) Van: 8, Bus: 55
C) Van: 12, Bus: 38 D) Van: 10, Bus: 71
Answer:
B
Step-by-step explanation:
v = how many students fit into a van
b = how many students fit into a bus
School A:
9v+7b=457 (1)
School B:
11v+7b=473 (2)
(1)&(2) => v=8
b=55
K(x) k(-3) 2x^2-5x+3
Answer:
When k(x) is 2x² - 5x + 3, k(-3) = 36.
Step-by-step explanation:
k(x) = 2x² - 5x + 3
Substitute the input of x.
k(-3) = 2(-3)² - 5(-3) + 3
Square -3.
k(-3) = 2(9) - 5(-3) + 3
Multiply 2 and 9.
k(-3) = 18 - 5(-3) + 3
Multiply -5 and -3.
k(-3) = 18 + 15 + 3
Add 18 and 15.
k(-3) = 33 + 3
Add 33 and 3.
k(-3) = 36.

2x + y = 6
Answer:
A solution is x=1 y=4
Step-by-step explanation:
find the value of U.
It's given that WXYZ is a parallelogram. In a parallelogram, the adjacent angles sum up to 180°. Here, 2u - 2 & 3u + 12 together make 180° because they are adjacent angles.
2u - 2 + 3u + 12 = 180
2u + 3u - 2 + 12 = 180
5u + 10 = 180
5u = 170
u = 170/5
u = 34

[] N + (n(t-1)) = T
I said this because you have N in the first hour, then after that you have n in t hours, which is equal to T. I subtracted one from t, because for the first hour it produces N.
(I think?)
[] It could also be N + (nt) = T without subtracting 1, but I think subtracting 1 makes sense as I stated above
