Answer:
Step-by-step explanation:
the first method :
s(x) = 2 - x and f(x) = 3x
(s f) (-7) = s(-7) ×f(-7)
but : s(-7) = 2 - (-7) =2+7 = 9
f(-7) = 3(-7) = - 21
so : (s f) (-7) = (9)×(-21) = - 189
the second method :
calculate : (s f) (x) == s(x)×f(x) = (2-x) 3x = 6x - 3x²
(s f) (-7) = 6(-7) -3 (-7)² = - 42 -147 = -189
Answer:
The answer is 40
Step-by-step explanation:
5*3=15
15*2=30
4*2.5=10
So 30+10=40
Hope this helps!!
Good evening ,
Answer:
<h2>53 and 47.</h2>
Step-by-step explanation:
let x and y represents the two uncknown numbers
then
x+y=100
x-y=6
then
2x=100+6=106
2y=100-6=94
then
x=106/2=53
y=94/2=47.

X = number of $85 trees, y = number of $95 trees
Logically, we can construct the expression 85x + 95y to represent how much Maple Grove spends on their trees in total. They want this cost to be less than or equal to $95,000. This means that the inequality has to be 85x + 95y ≤ 95000, either choice a or b. Since the community wants more $95 trees, they want y to be greater than or equal to x.
This means choice b: 85x + 95y ≤ 95000<span>, x</span>≤y is your answer.
Hope this helps!
Y=2x, rise/run. start from 0,0, go up the y axis until you see that the line hits a solid point which is 1,2.
