Answer:

x = 8

Step-by-step explanation:

17x - 4 = 12 + 15x \\ 17x - 15x = 4 + 12 \\ 2x = 16 \\  \frac{2x}{2}  =  \frac{16}{2}  \\ x = 8

Write the equation in POINT-SLOPE FORM of the line that passes throught (5,9) and has a slope of -7.
Debora [2.8K]

Answer:

The equation of line with slope -7 passing through (5,9) in point-slope form is:

y-9 = -7(x-5)

Step-by-step explanation:

Given

Slope of line = m = -7

Point = (5,9)

The point slope form of equation is obtained from a point and slope. It is given by the equation:

y-y_1 = m(x-x_1)

We know that (x1,y1) = (5,9)

Putting the values we get

y-9 = -7(x-5)

Hence,

The equation of line with slope -7 passing through (5,9) in point-slope form is:

y-9 = -7(x-5)

Mariana [72]

Answer:

83

Step-by-step explanation:

Angle 7 & angle 8 are supplementary angles, meaning they add up to 180º.

Angle 8 & angle 12 are corresponding angles, so they are equal.

If we solve for the measure of angle 8, it will be the same answer as angle 12.

Therefore, angle 7 & angle 12 add up to 180º.

80 + (x+17) = 180

Solve:

(80-80) + (x+17) = 180-80

X+17 = 100

X + (17-17) = 100-17

X = 83
