1/3 ( x - 10) = -4 ???

Pepsi [2]

Answer:

$x = - 2$

Step-by-step explanation:

1) Simplify 1/3 ( x - 10) to x-10/3.

$\frac{x - 10}{3} = - 4$

2) Multiply both sides by 3.

$x - 10 = - 4 \times 3$

Simplify 4 × 3 to 12.

$x - 10 = - 12$

4) Add 10 to both sides.

$x = - 12 + 10$

5) Simplify -12 + 10 to -2.

$x = - 2$

So, therefor, the answer is, x = -2.

Is y = 0.5x - 1 a liner function

Mama L [17]

$\text{Yes, it is a linear function}\\\\\text{The reason why it's a linear function is because there is a constant change}\\\\\text{The constant change would be your slope, and the slope in this case}\\\text{is 0.5}\\\\\text{If you plug this equation in a graph, it would be a straight line forever}\\\\\text{If you want to know if a line is linear, just check the slope to see if it's}\\\text{constant.}$
