I’m pretty sure you would have to make them equal
1. 3x -10=7x+14
2. Add 10 to both sides
3. 3x=7x+24
4. Subtract the variable ( 7x ) from both sides
5. -4x=24
6. Divide -4/24
I hope I did it right let me know if any errors

Write (5,0) with a slope of 2 in point-slope form.
neonofarm [45]
Y = mx + c 
m = 2
y = 2x + c

At (5, 0)
0 = 2(5) + c
c = -10

y = 2x - 10

Volume of a Cube Formula: V = a³

  • <em>a</em> is a side length

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>V</em> = 512 cm³

<u>Step 2: Find </u><em><u>a</u></em>

  1. Substitute in variables [Volume of a Cube Formula]:                                    512 cm³ = a³
  2. [Equality Property] Cube root both sides:                                                      8 cm = a
  3. Rewrite:                                                                                                             a = 8 cm
