Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

-4(x + 2) = 4(2 - 2x)

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide -4 on both sides:                    -(x + 2) = 2 - 2x
  2. Distribute negative:                           -x - 2 = 2 - 2x
  3. Add 2x on both sides:                       x - 2 = 2
  4. Add 2 on both sides:                         x = 4

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    -4(4 + 2) = 4(2 - 2(4))
  2. Multiply:                               -4(4 + 2) = 4(2 - 8)
  3. Add/Subtract:                      -4(6) = 4(-6)
  4. Multiply:                               -24 = -24

Here we see that -24 does equal -24.

∴ x = 4 is the solution to the equation.

Y-80x=65 in function notation
kolezko [41]

Answer:f(x) = 80x + 65f


Step-by-step explanation:

Since x = days and y = total rent, you've been given two points on your function: (5, 465) and (7, 625). We'll find the slope using those two points:

(625 - 465) / (7 - 5) = 160/2 = 80

Then, use m = 80 and one of the points to write the equation of your line in point-slope form:

y - y1 = m(x - x1)

y - 465 = 80(x - 5)

Convert that to standard form:

y = 80(x - 5) + 465

y = 80x - 400 + 465

y = 80x + 65

y - 80x = 65

In function notation, that's:

f(x) = 80x + 65

Is 23,27,and 29 a prime number? Show ur work
Eduardwww [97]
23 is a prime number because it is only divisible by (has factors of) 1 and itself (23).
27 is NOT a prime number because it is divisible by more than 1 and itself (also 3 and 9).
29 is a prime number because it is only divisible by 1 and 29.
