Answer:
3 and 5/8
Step-by-step explanation:
1 1/2 + 2 1/8 = 29/8
Simplify to 3 5/8
Answer:
64
Step-by-step explanation:
There are 5 counts in half a second
Answer:
the number is 5
Step-by-step explanation:
x^10 ÷ x^7 = 125
x^3 = 125
x = 5
Y=x^2+12x+30
8x-y=10
sub x^2+12x+30 for y in the secodn equaiton
8x-(x^2+12x+30)=10
8x-x^2-12x-30=10
-x^2-4x-30=10
times -1
x^2+4x+30=-10
add 10 both sides
x^2+4x+40=0
use quadratic formula
we find that we have 2 imaginary roots and therefor are not on the real plane, they are not plotted on the imaginary plane
no real solution
x=-2+6i or -2-6i
the interseciton on the imaginary plane is
(-2+6i, -26+48i) or (-2-6i,-26-48i)
