-2 + -1 = -3 And -10 x 10 =100
A) n= number of blocks in a bag
B) 20
C) it says partner but if u have to do it, i would say yes it’s useful because even though it’s a different variable, you can use any variable to indicate the # of blocks in a bag
Answer:
Step-by-step explanation:
I don't know what your choices were, but
8p^2 + 23 = 8p^3 + 27 - 4
= ((2p)^3 + 3^3) - 4
= (2p+3)(4p^2-6p + 9) - 4
I belive it is a constant
we conclude that for 500 miles, both plans will have the same cost.
<h3>
For how many miles both plans have the same cost?</h3>
Plan A charges a fixed amount of $75, plus $0.10 per mile, so if you drive x miles, the cost equation is:
A(x) = $75 + $0.10*x
For plan B we will have the similar equation:
B(x) = $100 + $0.05*x
The cost is the same in both plans when:
A(x) = B(x)
So we need to solve the linear equation:
$75 + $0.10*x = $100 + $0.05*x
$0.10*x - $0.05*x = $100 - $75
$0.05*x = $25
x = $25/$0.05 = 500
So we conclude that for 500 miles, both plans will have the same cost.
