This is a vertical angle, and so the angle measurements will have the same measurement.


(4x + 7) = [5(x - 4)]


First distribute the 5 to x and -4


5(x -4) = 5x - 20


4x + 7 = 5x - 20


Next, isolate the x. Subtract 5x from both sides and 7 from both sides


4x (-5x) + 7 (-7) = 5x (-5x) - 20 (-7)


4x - 5x = -20 - 7


Next, simplify.


4x - 5x = -20 - 7


-x = -27


Isolate the x, divide - 1 from both sides


-x/-1 = -27/-1


x = -27/-1


x = 27


27 is your answer for x



hope this helps

PLEASE HELP!!!!!!!!
Flura [38]

the answer is A ,when x=0,g(x)is-1,so when u add x into the g(x),which is  given below,u can find C,D,E,g(x) is no equal to -1,when you add x=1 into g(x)(A,B),you can find g(x) of B is 0,which is no equal the answer giving above(g(x)=2),but A is all right.

Three roots of a fifth degree polynomial function f(x) are -2, 2, and 4 + i. Which statement describes the number and nature of
Juli2301 [7.4K]

We know that imaginary roots always come in pairs, so we already know 4 solutions

-2, 2, 4 + i and a pair of 4 + i

Since imaginary roots always come in pairs we wont have more than 2 imaginary roots, since its a fifth degree root and we can only have 5 roots

So for sure, we will have 3 real roots and 2 imaginary roots

Last option, f(x) has three real roots and two imaginary roots
