Use ac method
for ax²+bx+c=0 when a≠1
multiply a and c, let's call the product r
what 2 numbesr multiply to get r and add to get b
2y²+9y+9=0
2*9=18
wat 2 numbers multiply to get 18 and add to get 9
3 and 6
split it up to that
2y²+3y+6y+9=0
group
(2y²+3y)+(6y+9)=0
factor
y(2y+3)+3(2y+3)=0
undistribute
(y+3)(2y+3)=0
set to zero
y+3=0
y=-3
2y+3=0
2y=-3
y=-3/2
y=-3 and -3/2
it's factored form is (x+3)(2x+3)
Answer:
decay: a, b
growth: c, d, e, f
neither: g
Step-by-step explanation:
A function is exponential if it has the independent variable in an exponent. g(x) is a linear function, not an exponential function.
__
An exponential function is a growth function if the coefficient of the variable is positive and the base of the exponent is greater than 1. It is a decay function if the exponent is positive and the base is less than 1.
The first two functions are decay functions. The remaining four exponential functions are growth functions.
Answer:
317
Step-by-step explanation:
951/ 3 is 317
for this problem you can use a calculator, or long division.
Multiply the rate per mile by the miles and the appropriate conversion factor.
