Answer:
-4a^2+7a+4 , a=2 or -1/4
Step-by-step explanation:
Take -4 + 3a2 from 7a - a2
It means 7a -a^2 - (-4+3a^2)
7a -a^2 +4-3a^2
7a -a^2-3a^2+4
7a -4a^2+4
-4a^2+7a+4
-4a^2+8a-a+4
-4a^2-a+8a+4
-a(4a+1)+2(4a+1)
(-a+2)(4a+1) =0
-a+2=0 4a+1=0
-a=-2 4a=-1
-a/-1=-2/-1 a=-1/4
a=2 or -1/4
The correct answer would be A. x=20/3 because it is proportional.<span />
Answer:
<h2>
The Slope Is <u>
12</u></h2>
Step-by-step explanation:
Below are the steps to follow to find the slope of any line.
First you need to pick two points. I chose (2,24) and (4,48). (It does not mater what points you chose.)
Now follow the equation
Slope (m) = ΔY/ΔX
ΔY = 48 – 24 = 24
ΔX = 4 – 2 = 2
24/2 = 12
Then no mater what points you chose, 12 should be your final answer
Answer:
5^4
Step-by-step explanation:
When dividing exponents with the same base, you subtract their exponents.
8-4=4
This means that 5^8 / 5^4 is equal to:
5^4
The correct answer is idk for me
