Answer:
61
Step-by-step explanation:
This composite function can be easily solved
First solve f(-2)
f(-2)=(-2)³+3
f(-2)=-8+3=-5
Now plug -5 for x in function g(x)
=2(5)²+2(5)+1
=50+10+1
=61
Answer:
$3 per notebook.
Step-by-step explanation:
i would start by taking the two notebooks away from the imaginary cart.
then a $30 backpack=10 notebooks.
if so, then, each notebook=$3 because 3x10=30.
if you re-add the two other notebooks then it would be twelve $3 notebooks=$36 ($30 backpack and two $3 notebooks) and 12x3=36 and 36=36
Step-by-step explanation:
Increasing linear functions are equations of the form y = mx + c, where m > 0.
Therefore y = -0.5x + 0.5 is not increasing.
We have the following line slopes:
- y = 2.5x + 10, m = 2.5
- y = 1.5x - 5.5, m = 1.5
- y = 0.5x - 2, m = 0.5
- y = 4/3 x - 7/3, m = 4/3
- y = 0.75x - 10, m = 0.75
The slopes in increasing order
are 0.5, 0.75, 4/3, 1.5 and 2.5 respectively.
Hence we have the answers for the boxes starting from the bottom-up:
- y = 0.5x - 2 (4th box)
- y = 0.75x - 10 (Last box)
- y = 4/3 x - 7/3 (5th box)
- y = 1.5x - 5.5 (3rd box)
- y = 2.5x + 10 (1st box)

A,B,C,E
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
we are given the equation
<u>x/h + 1 = 2 </u>
we are also given a the<u> value of h = 4 </u>
<u>we are told to find x </u>
let's use the equations and substitute in what we have first
x/h + 1 = 2 ➔ x/4 + 1 = 2
now we can solve for x
x/4 + 1 = 2
lets begin by subtracting one from both sides
now we are left with
x/4 = 1
now do the inverse of division which is multiplication
so we multiply both sides by the denominator 4
now we have
x = 4
Hope this helps!! :)
