Answer:  

x=21

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+5+5x+7=180

Step 1: Simplify both sides of the equation.

3x+5+5x+7=180

(3x+5x)+(5+7)=180(Combine Like Terms)

8x+12=180

8x+12=180

Step 2: Subtract 12 from both sides.

8x+12−12=180−12

8x=168

Step 3: Divide both sides by 8.

8x /8 = 168 /8

x=21

What is the rate of change of the function y = − 1/4 x + 1
scoray [572]

Answer:

-1/4

Step-by-step explanation:

Hello!

The rate of change is also known as the slope.

Standard equation of a line: y = mx + b

  • y: output
  • m:  slope
  • x: input
  • b: y-intercept

So, if we match the standard form to the given function:

  • y = mx + b
  • y = -1/4x + 1

-1/4 is m, or the rate of change.
