A retail store is having a sale on toilet paper. At 2:00 PM, the
store had sold a total of 15 packs of toilet paper. At 5:00 PM,
the store had sold a total of 57 packs.
Assuming that it is positive, what is the average rate of change
between 2:00 PM and 5:00 PM?
Answer:
14.25 packs per hour
Step-by-step explanation:
it is 4 hours from 2:00-5:00 so... 57÷4=14.25 packs per hour
The average rate of change between 2:00 PM and 5:00 PM will be 14 packs per hour.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables. The term "rate of change" refers to the pace at which one quantity changes with respect to another.
Given that, a retailer is offering discounted toilet paper. The shop sold a total of 15 packs of toilet paper around 2:00 PM. The shop has sold 57 packets as of 5:00 PM.
The average rate of change between 2:00 PM and 5:00 PM is obtained by taking the ratio of the change to the number of packs sold to the time elapsed as,
=( 57 - 15 ) / 5 - 2
=42 / 3
= 14 packs per hour.
Thus, the average rate of change between 2:00 PM and 5:00 PM will be 14 packs per hour.

Zuri quickly solved the problem and told her team, "Hey! I go it m\large \angleA = 93°, m\large \angleB = 63°, m\large \angleC = 36°. Done!" Mikaya and Olivia are suspicious. Does Zuri have the correct answer, or are Mikaya and Olivia correct to be suspicious? Explain completely. Be clear, specific, and detailed.
Answer:
Mikaya and Olivia are correct to be suspicious
Step-by-step explanation:
Sum of the angles of a triangle is always 180
But, The sum of all angles of the triangle that Zuri solved = 93 + 63 + 36 = 192 ≠ 180
So, Zuri is wrong

Each pair of supplementary angles is congruent.
Each pair of alternate interior angles is congruent.
Answer:
Step-by-step explanation:
Each pair of vertically opposite angles are equal. If you mean vertical angles as in 90 degrees, you should qualify the question
Each pair of alternate interior angles is congruent (think it should be are congruent).
Each pair of corresponding angles is congruent

The table represents some points of a linear function.
Which function represents the same relationship?
A. h(x) = -3x - 10.5
B. h(x) = -x - 3.5
C. h(x) = 3x - 10.5
D. h(x) = x - 3.5
The linear function will be represented as h(x) = -3x - 10.5. The correct option is A.
What is a linear function?The terms "linear function" in mathematics refer to two different but related ideas: A linear function is a function with a graph that is a straight line in calculus and related fields.
The given data in the table is:-
X -7.5 -3.5 -1 2
Y 12 0 -7.5 -16.5
The linear function can be written as:-
y = mx + c
m = ( 0 - 12 ) / ( -3.5 + 7.5 )
m = -12 / 4
m = -3
The y-intercept will be:-
y = mx + c
0 = ( -3 x -3.5 ) +c
c = -10.5
The linear function is:-
h(x) = -3x - 10.5

Write a piecewise function for the graph.
Similar to Modulus, but It's separated.
Since both are separated, that means - they are both linear function.
The range is greater than all negative numbers. That means y ≥ 0
( 1 ) For the blue graph,
y = -x-3 {y ≥ 0} ---------- Blue Graph Answer
-x-3=0
-x=3
x=-3
We can clearly see that the slope is -1.
And intercept x-axis at (-3,0)
( 2 ) For the red graph.
y = 2x+6 { y ≥ 0} ---------- Red Graph Answer
Notice that the slope is 2.
And intercept x-axis at (-3,0)
Also intercept y-axis at (0,6)
2x+6=0
2x=-6
x=-3
---------- Only linear function with given y ≥ 0 can draw that. (Only separated graph.) --------------

Solve the following equation for x.
5/8x +4 = 3/8x +12
Answer:
x=32
Step-by-step explanation:
8(5/8x+4 = 3/8x+12)
5x+32=3x+96
2x+32=96
2x=64
x=32
Answer:
x = 32
Step-by-step explanation:
5/8x + 4 = 3/8x + 12
subtract 3/8 from both sides
2/8x + 4 = 12
simplify
1/4x + 4 = 12
subtract 4 from both sides
1/4x = 8
multiply each side by the reciprocal of 1/4
4/1 • 1/4x = 8 • 4/1
solve
x = 32
