Y= -x-1
y= -5x-17 Multiply the 1st equation by (-1) & then add up the result to the 2nd one:
-y = -1(-x) -1(-1)
y = -5x-17
-----------------
0y = -4x-16 ===> x=-4 & y=3

Hi! I'm not sure of the answer to this.
andriy [413]

Answer:

y - 2 = (-3/7)(x + 5)

Step-by-step explanation:

Recall that the slopes of a line and another line perpendicular to the first are negative reciprocals.

The slope of the given line is 7/3.  The negative reciprocal of that is -3/7.  Thus, we immediately eliminate the fourth answer choice.

We must now find the equation of the perpendicular line, with slope -3/7, that passes through (-5, 2).  We'll do that using the point-slope formula for the equation of a straight line.

That formula is    y - k = m(x - h), where m is the slope and (h, k) is the given point.

Substituting 2 for k, -5 for h and -3/7 for m, we get:

y - 2 = (-3/7)(x + 5).  This matches the 3rd given possible answer.

Quiana has 7 times more text messages from Yolanda than from Pierre. Quiana has 56 text messages from Yolanda. Which equation ca
gizmo_the_mogwai [7]

Answer:

Quiana has 8 text messages from Pierre.

Step-by-step explanation:

This question can be solved using a rule of three.

Quiana has 7 times more text messages from Yolanda than from Pierre.

This means that for each message that she receives from Pierre, she receives 7 from Yolanda.

She received 56 from Yolanda.

So

7 messages from Yolanda - 1 messages from Pierre

56 messages from Yolanda - x messages from Pierre

7x = 56

x = \frac{56}{7}

x = 8

Quiana has 8 text messages from Pierre.
