What is the answer to 2x-2=-5

1 answer:

5 0

Using the Transformation formula.

2x - 2 = -5

Add 2 to both sides.

2x - 2 + 2 = -5 + 2

2x = -3

Divide both sides by 2

$\frac{2x}{2}$ = $\frac{-3}{2}$

x = $\frac{-3}{2}$

The answer is 8 and 13

<span>
y = ax + b
y = 4, x = 1 </span>⇒ 4 = a + b
y = 6, x = 3 ⇒ 6 = 3a + b

Solve the system of equation:
a + b = 4
3a + b = 6
______
b = 4 - a
3a + b = 6
______
3a + 4 - a = 6
2a + 4 = 6
2a = 6 - 4
2a = 2
a = 2/2 = 1
b = 4 - a = 4 - 1 = 3

So, the function rule is: y = x + 3

Thus, if x = 7, then y = 7 + 3 = 10
If x = 10, then y = 10 + 3 = 13

x y
1 4
3 6
4 7
5 8
7 10
10 13
