choose an equation in slope-intercept form for the line that passes through (-8,1) and is perpendicular to the y=2x-17. select o

Fed [463]

Y = 2x - 17, comparing to y = mx + c, slope m = 2.

If perpendicular, the new slope would be -1/2, that is the negative reciprocal of 2.

And passing through (-8 , 1).

using y = mx + c, and x = -8, y = 1, m = -1/2

1 = -1/2*-8 + c

1 = 4 + c

1 - 4 = c

c = -3

y = mx + c, substituting m = -1/2, and c = -3, y = -(1/2)x - 3.

Option C.

Which graph shows the solution to the inequality -3x-7 <20?

ki77a [65]

Answer:

x > -9

Step-by-step explanation:

The solution to the inequality is obtained as follows:

-3x -7 < 20

-3x - 7 + 7 < 20 + 7

-3x < 27

-3x/(-3) > 27/(-3)

x > -9

Notice that when you divide by a negative number, the inequality sign changes.

In the picture attached, the graph of the solution s shown. Notice that -9 is not included in the solution.
