(Will give Brainliest) Explain what the graph of the function represents. Be sure to use complete sentences.
Irina-Kira [14]

Answer: f(-735) = -\frac{2}{3}(-735) + 490 = 980

Step-by-step explanation:

f(x) = -\frac{2}{3} x + 490 =0  Subtract 490 from both sides

        \frac{3}{2}* -\frac{2}{3} x = -490 *\frac{3}{2}   Then flip -\frac{2}{3} multiply both sides by \frac{3}{2} to cancel out -\frac{2}{3}

      x= -735  Thus giving you -735 as your x.

Then you plug it back into the equation to solve.

What are the solutions to the equation (x+5)2=32 ?
Vsevolod [243]

Answer:

x = 11

Step-by-step explanation:

(x+5)2 = 32

2x + 10 = 32

HELP...

1. 4x + 2y = 11

x - 2 = -2y


First I would isolate one of the variables (x or y) of one of the equations, and then substitute it into the other equation.

The easiest to isolate is the "x" in the second equation

x - 2 = -2y  Add 2 on both sides

x = -2y + 2

Substitute this into the first equation


4x + 2y = 11

4(-2y + 2) + 2y = 11   Multiply 4 into (-2y + 2)

-8y + 8 + 2y = 11  Combine like terms

-6y + 8 = 11  Subtract 8 on both sides

-6y = 3   Divide -6 on both sides

y = -3/6  Simplify

y = -1/2


Now that you know "y", you can plug it into either of the original equations to find "x"

x - 2 = -2y

x - 2 = -2(-1/2)

x - 2 = 1    Add 2 on both sides

x = 3


Answer is A


2. y = 3x + 5

4x - y = 5

Substitute the first equation into the second equation

4x - y = 5

4x - (3x + 5) = 5   Multiply/distribute the - into (3x + 5)

4x - 3x - 5 = 5  Combine like terms

x - 5 = 5  Add 5 on both sides

x = 10


Plug in "x" into either of the original equations to find "y"

y = 3x + 5

y = 3(10) + 5

y = 30 + 5

y = 35


Answer is A
