You cannot assume the angles add to 90, but you know since BD is an angle bisector that ABD is equal to DBC, or x-5=2x-6

x=1. this is the correct solution to the equation but gives negative angles when plugged in which isn't possible. there must be something wrong work the question

Wha is 3x+3y=-9 in standard to slope intercept form simplified, thank you!
Alona [7]

Answer

Step-by-step explanation:

The answer would be y=-x-3. 3x+3y=-9 is in standard form and you want it to be in y=mx=b form (slope-int) so subtract 3x by both sides. Now, you have 3y=-3x-9. Divide 3 to both sides, now you will get y=-x-3.

(7x-6)(8x+3)

Use the FOIL method

F:  7x • 8x = 56x^2
O: 7x • 3 = 21x
I: -6 • 8x = -48x
L: -6 • 3 = -18

56x^{2}+21x-48x-18

Simplify
56x^{2}-27x-18

Your answer is A.
