olga2289 [7]4 years ago
3 0

Answer:

x = -1

Step-by-step explanation:

subtract 36 from both sides

36 - 5x - 36 = 7x + 48 - 36

simplify

-5x = 7x + 12

subtract 7x from both sides

-5x - 7x = 7x + 12 - 7x

simplify

-12x = 12

divide both sides by -12

-12x/-12 = 12/-12

simplify

x = -1

Write the Slope-Intercept Form of the eq. through point (-5, 2) and perpendicular to: y = x - 2
nataly862011 [7]

Answer:

y =qxe+b  

Step-by-step explanation:

Write the Slope  

− Intercept Form of the eq through point  (−5,2) and perpendicular to:  

y =x−2

Find the value of  b  using the formula for the equation of a line.

y =mx+b

Replace the known value of  m  in the slope y-intercept form of the equation.

y =(eq)⋅x+b

Simplify the slope y-intercept form of the equation.

Remove parentheses.

y =(eq)⋅x+b

Simplify  (eq)⋅x+b.

Multiply eq by x.

y =eqx+b

Move e .

y =qxe+b

Complete the table of values below so that it represents a line with a constant rate of change of `-\frac{3}{4}.`
Nady [450]

To find values of the table, plug in the given corresponding values of x or y, and constant rate of change (m) = -3/4 into y = mx.

<h3>What is the Constant Rate of Change?</h3>

Constant rate of change of any table or function is a comparison of how two variables are changing, which can be determined using the formula, m = change in y/change in x = \frac{y_2 - y_1}{x_2 - x_1}.

Where x and y are the coordinates of a table or functions, and m is the constant rate of change, the equation that models the relationship would be, y = mx.

The image of the table is missing, however, to complete the given table, plug in any of the given values of x or y, and constant rate of change (m) = -3/4 into y = mx.
