We can subsitute since
23x+4=y and
4-2x=y
therefor
23x+4=y=4-2x
so
23x+4=4-2x
minus 4 on both sides
23x=-2x
add 2x to both sides
25x=0
divide both sides by... uh oh
I guess x=0
sub
4-2(0)=y
4-0=y
4=y
the solution is (0,4)
(17x+19)+(19x-15)=180
36x+4=180
36x=176
x=44/9 which is approximately 4.8
mmTherefore mmmIn conclusion m
Answer:
X is 2 bcz 3+5 is 8 then 8/4 is 2
Answer:
$1.2
Step-by-step explanation:
Given the total cost, in dollars, given by the function c(p) = 1.2p.
If p = 1
c(1) = 1.2(1)
c(1) = $1.2
If p = 2
c(2) = 1.2(2)
c(2) = $2.4
If p = 3
c(3) = 1.2(3)
c(3) = $3.6
If p = 4
c(4) = 1.2(4)
c(4) = $4.8
Common difference = c2 - c1 = c3 - c2 = c4 - c3
Common difference = 2.4 - 1.2 = 3.6 - 2.4 = 4.8 - 3.6 = 1.2
Hence the common difference is $1.2
