Answer:

B, C, F

Step-by-step explanation:

Given:

\left\{\begin{array}{l}4x+3y=12\\ \\2x+3y=-6\end{array}\right.

Subtract the second equation from the first equation:

(4x+3y)-(2x+3y)=12-(-6)\\ \\4x+3y-2x-3y=12+6\\ \\2x=18\\ \\x=9

Option B "The x coordinate of the solution is 9" is ture

Substitute it into the first equation:

4\cdot 9+3y=12\\ \\36+3y=12\\ \\3y=12-36\\ \\3y=-24\\ \\y=-8

Option F "The y coordinate of the solution is -8" is true.

Point (9,-8) is in the IV quadrant, so option C is true.

In the figure, line segment VR is parallel to line segment US and m<1 = 45 degrees what is m<4?
Jobisdone [24]

The measure of ∠4 is 45°.

Solution:

Line segment VR is parallel to the line segment US.

m∠1 = 45°

∠1 and ∠4 are corresponding angles.

<em>If two lines are parallel, then the corresponding angles are congruent.</em>

m∠1 = m∠4

45° = m∠4

m∠4 = 45°

The measure of ∠4 is 45°.
