Answer:
multiplication property of equality. Hope this help and maybe a brainlist?
Step-by-step explanation:
I'm assuming the given function is f(x) = 15x^2 + 10x.
If so, then,
f(x) = 15x^2 + 10x
f(x) = 15*(x)^2 + 10*(x)
f(-1) = 15*(-1)^2 + 10*(-1) ... note how x is replaced with -1
f(-1) = 15*(1) + 10*(-1)
f(-1) = 15 - 10
f(-1) = 5
Therefore the answer is 5
ANSWER:
Instead of greater than, the inequity symbol should be greater than or or equal to.
Step-by-step explanation:
We know the variable x represents the number of students. We also know there are 5 chaperones attending; this makes x+5 , by 2.50
It costs $2.50 per person; this means we multiply the number of people, x+5, by 2.50:
2.50(x+5)
The class has $90 to spend; this means they can spend up to and including $90. This gives us
90>2.50(x+5)

Answer:
Step-by-step explanation:
c = $6.25 + 0.15w
$6.25 represents the fixed cost. it is the cost that does not vary with the number of words
15 cents is the variable cost. it is the cost that varies with the number of words.
to write the equation convert 15 cents to dollars by dividing by 100.
