For function one, the slope is already in mx+b form. The coefficient to x is the slope, so it is four in this case. For the second function we calculate the slope using rise over run. The rise is change in y and run is change in x, so 4/2= 2 slope. Four is greater than two so it has the greater rate of change. The answer is B
I just copied and pasted my previous answer as this is the same question I believe

Correct option - B

The first function -> y = 4x + 5
It is in the form - mx + c
The slope ,m = 4

Now second function will be
y - y1 / x - x1 = 10 - 6 / 3 - 1 = 4/2 = 2
So for second function, m = 2

Now comparing them, we get the correct answer as B

The length of a rectangular mural is 2 ft more than three times the height. The area is 165 ft^2. Find the height of the mural.
NISA [10]

Answer:

x=-1±4√31/3 ft is the height

Step-by-step explanation:

let the height be x ft.

then the length would be 3x+2

area = L*H= x(3x+2)

165=3x²+2x

0= 3x²+2x -165

dividing the whole equation by 3

0=x²+2x/3-55

(x)²+2(x)(1/3) +(1/3)² -55 -(1/9)=0

(x+1/3)²- 495-1/9=0

(x+1/3)²= 496/9

taking square root on both sides

(x+1/3)= ±4√31/3

x= ±4√31/3-1/3

x=-1±4√31/3 ft is the height

Solve the system of equations: x – 4y = –8 and –3x + 12y = 24.
ale4655 [162]
It should be C
Because when u multiply ( -3)*(x-4y= -8)

It’ll equal to -3x+12y=24 which is the same equation to the other one.
When the equations r the same, it means everything on the line is the solution for this system of equation.

Write two subtraction equations to show how to find 15-7
IrinaVladis [17]
I believe that,that is the only form you can write it because if you do 7-15 it's -8 so that's the only way that you can write it.
