Answer:

yes

Step-by-step explanation:

Substitute x = - 8 and y = - 7 into the equation

If both sides are equal then (- 8, - 7) is a solution

left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14

right side = 2y = 2(- 7) = - 14

Since both sides are equal then (- 8, - 7) is a solution to the equation

What is the next step in this construction?

bezimeni [28]

<u>Answer:</u>

The correct answer option is B. Construct a line perpendicular to XP through point A.

<u>Step-by-step explanation:</u>

We are given an incomplete figure of construction of a perpendicular line and we are to determine whether which of the given answer options is the next step in the construction.

From the given marks, we can deduce that a perpendicular line to XY is being constructed, passing through P.

So the next step must be to construct a line perpendicular to XP through point A to complete the construction.
