2x-4=5,
2x=5+4
2x=9
x=9/2
2x-4=-5
2x=-5+4
2x=-1
x=-1/2
Equation #1 has 2 solutions
|3x-4|= -12 has no solution cause |x|> or equal 0
⇒ Equation #1 has more solutions
Answer:
81
Step-by-step explanation:
x² + 18x
x² + 2(x)(9) + 9²
x² + 2(x)(9) + 81
(x + 9)²
The arcs have to intersect to give a point which will connect to the vertex of the angle that you are bisecting.
-3x + 7 = 4
-3x = -3
x = 1
4(1) - 4
4-4
0
Answer:
b(20) = 60
Step-by-step explanation:
Here, given that ;
b(x) = -2(x-50)
we want to find the value of b(20)
what we need to do is to simply substitute x for 20
That will be:
b(20) = -2(20-50)
b(20) = -2(-30)
b(20) = 60
