5^y=12
Y*log(5)=log(12)
Y=log(5)/log(12)
Y=1.53

or
![\frac{1}{64}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B64%7D)
Step-by-step explanation:
four to the negative power of 3 is = 4⁻³
Answer:
x=6
Step-by-step explanation:
(x^2 – 3x - 10) = (x + 2)
Factor the term on the left
(x-5) (x+2) =x+2
Divide each side by x+2
x-5 = 1
Add 5 to each side
x-5+5 =1+5
x=6
Answer:
7.83
Step-by-step explanation:
cos(40)=6/(ZX)
zx=7.83
Y = 6x - 15
(8,?)....x = 8, so sub in 8 for x and solve for y
y = 6(8) - 15
y = 48 - 15
y = 33......(8,33)
(-1,?)
y = 6(-1) - 15
y = -6 - 15
y = - 21.....(-1,-21)
(5,?)
y = 6(5) - 15
y = 30 - 15
y = 15......(5,15)
