8, 8 2/7, 26/3, 8.8
(You have to change 8 2/7 to 8.28 and 26/3 to 8.66
I'll just repost it here.
An exponential function is expressed in the form y=axb^x. The relation represents a growth when b>1 and a decay when 0<b<1.
Answer: x = 1 and x = -7
Explanation:
x^2 + 6x - 7 = 0
x^2 + 6x + 3^2 = 7 + 3^2
(x + 3)^2 = 16
x + 3 = +-4 (square both sides)
x + 3 = 4
x = 1
x + 3 = -4
x = -7
Answer:
m+n=9
Step-by-step explanation:
Put the equation into the form ka^mb^n by multiplying the coefficients (-1*2*-3), so k= 6, then add the exponents of a together, a^2+a^1= a^3, m=3.
Now you have 6a^3, next we do the exponents of b together, b^3, b^2, b^1= b^6, n=6.
This is 6a^3b^6. m=3 and b=6, so add m+n=9.
Left: 1-2 and the right: 34-68
