Answer: 9^2 (81)+8^2(64)=12.04^2(144.97) which rounded/estimated is equal to 145
Answer: Rafael is incorrect
Step-by-step explanation: 5 is not equal to -5. It is the additive inverse, or negative reciprocal.
They intersect so therfor PIR=SIM
so therefor 4x+24=7x+3
minus 4x both sides
24=3x+3
minus 3 both sides
21=3x
divide both sides by 3
7=x
x=7

Situation:
You are signing up for a book club. The get-in price is 6. Every month, you have to pay 2 dollars.
How This Works:
y=mx+b
M=Slope
B=y intercept.
Y intercept is the starting point. The beginning out. In this case, the y intercept is 6. So, in our situation, 6 is the joining fee. The beginning amount. Slope is the the rate of change. The slope in this problem is 2. Since the monthly fee is 2, that would make it the slope
there are 10 numbers you want either a 4 or 7 ( 2 numbers)
so probability is 2/10 which reduces to 1/5
