The answer is 0.8
15x^2=12x
15x=12
x=12/15 = 4/5 so the answer is 0.8
Answer:
y= 25
i think
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
Given the function

and 
let f(x)=y
Substitute in f(x)

From the definition inverse function
if
⇒ 
Substitute this in the above expression

Substitute y=10
⇒

Therefore a=15
Answer:
A. -3x^2+7x-1
Step-by-step explanation:
(3x^2+3x-3)-(6x^2-4x-2)
3x^2+3x-3-6x^2+4x+2
-3x^2+7x-1
Answer:
rate of change=slope= y2-y1/x2-x1
Step-by-step explanation:
x: -2|-1|0|1
y : 5|4|3|2
so choose 2 ordered pairs. in this case, we will choose (-2,5) and (-1,4)
now we plug them in: 
4-5=-1
-1-(-2)=1
so -1/1 is equal to -1, meaning it's answer option b.
