Which are solutions of the equation 4x2 – 7x = 3x + 24? Check all that apply. x = –4 x = –3 x = -3/2 x = 2/3 x = 2 x = 4
Ivahew [28]
4x2 - 7x = 3x + 24
 First we rewrite the quadratic equation:
 4x2 - 7x - 3x - 24 = 0
 4x2 - 10x - 24 = 0
 The solutions to the quadratic equation in this case are:
 x1 = 4
 x2 = -1.5
 Answer:
 x = -3/2
 x = 4

Angles D and F are supplementary, so
.. (19x -26) +(7x -2) = 180
.. 26x = 208
.. x = 208/26 = 8

∠EFG = (7x -2)° = (7*8 -2)° = 54°

Selection C is appropriate.

I need help with this problem! Must explain why.
OLEGan [10]

Answer:

95°

Step-by-step explanation:

Angle 1 and 4 are opposite angles, thus equal, so:

3x+10 = 4x-15 =>

x = 25

Angle 1 and 4 are 85°

Angle 4 and angle 6 are called allied (or co-interior) angles, which are supplementary, i.e., angle 6 = 180 - angle 4, so angle 6 = 95°.

Angle 6 and 7 are again opposite, so angle 7 is 95° as well!
