Since those lines are parallel, those two angles are equal. Therefore:
3x+15=105
3x=90
x=30
750/x=25/100
750x100=75,000
75,000/25= 3,000
75,000+3,000= 78,000
0=4(x²+8x+16)-12
0=4x²+32x+64-12
0=4x²+32x+52
0=x²+8x+13
D=b²-4ac
D=64-52=12
x=(-b-√D)/2a
x=(-b+√D)/2a
x=(-8-2√3)/2= (-2(4+√3))/2= -(4+√3)
AND
x=(-8+2√3)/2=-2(4-√3)/2= -(4-√3)
Answer:
n = 8
Step-by-step explanation:
The angles are vertical angles and so they are equal
9n = 8n+8
Subtract 8n from each side
9n - 8n = 8n+8-8n
n = 8
Answer:
A
Step-by-step explanation:
We only need to calculate one of the functions shown. I will be using |x| - 1 because it is the simplist.
|x| makes a V shape and we know it only goes from -1 to 1. And that means it can be A or D. Next we apply the -1 so that it will go down. The only option that fits this is option A.
