Equality Properties

Step-by-step explanation:

Step 1: Define equation

-12(a - 2) = -50

Step 2: Solve for a

Divide -12 on both sides: a - 2 = 25/6
Add 2 on both sides: a = 37/6

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Substitute in a: -12(37/6 - 2) = -50
Subtract: -12(25/6) = -50
Multiply: -50 = -50

Here we see that -50 does indeed equal -50.

∴ a = 37/6 is a solution of the equation.

Answer:

a = $\frac{37}{6}$

Step-by-step explanation:

-12(a - 2) = -50

-12a + 24 = -50

-12a = -74

a = $\frac{74}{12}$ = $\frac{37}{6}$

Answer:

The linear equation for the line which passes through the points given as (-1,4) and (5,2), is written in the point-slope form as $y=\frac{1}{3} x-\frac{13}{3}$ .

Step-by-step explanation:

A condition is given that a line passes through the points whose coordinates are (-1,4) and (5,2).

It is asked to find the linear equation which satisfies the given condition.

Step 1 of 3

Determine the slope of the line.

The points through which the line passes are given as (-1,4) and (5,2). Next, the formula for the slope is given as,

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Substitute 2&4 for $y_{2}$ and $y_{1}$ respectively, and $5 \&-1$ for $x_{2}$ and $x_{1}$ respectively in the above formula. Then simplify to get the slope as follows,
