Answer:
Step-by-step explanation:
is g(x) equal to 2x²-1, or 2x²+1 ?
f(x) = x²-3
g(x) = 2x²-1
g(f(x)) = g(x²-3) = 2(x²-3)²-1 =2(x⁴-6x²+9)-1 =
2x⁴-12x²+17
Answer:
6x^2 + 8x + 28
Step-by-step explanation:
2 times the length plus 2 times the width gives the perimeter
2(3x^2 + 3x + 6) + 2(x + 8)
6x^2 + 6x + 12 + 2x + 16
6x^2 + 8x + 28
Answer:77
Step-by-step explanation:
132 divided by 12(7+5) is 11
11*7=77 so theres 77 boys
Answer:
0
Step-by-step explanation:
slope = y2 - y1 / x2 - x1
(-2,5) (6,5)
5-5/-2-6
0 / -8
slope is 0
This is the concept of algebra, we solve the question as follows:
The cost of renting a camping tent is y
The number of days is x
cost is proportional to number of days, thus:
yαx
y=kx
where k is the constant of proportionality.
If y=$56 when x=7 days, then:
56=7k
hence:
k=56/7=8
therefore:
y=kx will be:
y=8x
the equation in slope intercept form which is y=mx+c is y=8x. In our case c=0 because there was no initial payments required to rent apart from the daily charges.
