Mikayla subtracted 4 from both sides in the beginning when she should've added it to both sides to cancel it out on the right. the correct answer should actually be x=1

Answer:

Mikayla subracted 4 from both sides, not add. She was supposed to add so that the -4 can cancel out.

The correct answer would be x=1

Soive the equation for the given va<br> a. -3x + 4y = -12 Solve for y.

Fynjy0 [20]

Answer:

Explanation:

−3x + 4y = −12

<em>Add 3x to both sides</em>

−3x + 4y + 3x = −12 + 3x

4y = 3x − 12

<em>Divide both sides by 4</em>

4y / 4 = 3x − 12 / 4

<em>Simplify</em>

<em>y = ¾x - 3</em>

Write the equation of a line perpendicular to y=1/2x + 8 that passes through ( 4, 9 ).

iogann1982 [59]

Answer:y = - 2x + 17

Step-by-step explanation:

The equation of a line, represented in the slope-intercept form, is

y = mx + c

Where

Slope = m

c = intercept

Looking at the equation given,

y=1/2x + 8

Slope,m = 1/2

If a line is perpendicular to a another line, then the slope of one line is equal to the negative reciprocal of the other line. It means that the slope of the perpendicular line that passes through that passes through ( 4, 9 ) will be -2

To determine c,

We will substitute m = -2, y = 9 and x = 4 into the slope intercept equation,

y = mx + c. It becomes

9 = -2 × 4 + c

9 = -8 + c

c = 9 + 8 = 17

The equation becomes

y = - 2x + 17
