Answer:
44a
Step-by-step explanation:
Because there is no variable other than a, this problem is relatively simple.
1. 8a + 14a = 22a
2. 22a + 27a = 49a
3. 49a - 5a = 44a
Answer:
44a
Step-by-step explanation:
8+14+27-5=44
8a+14a+27a-5a=44a

A car travels 120 miles in 3 hours at a constant speed. How long will it take for the car to travel 200 miles?
Answer:
5
Step-by-step explanation:
To calculate the travel speed per hour, divide 120 by 3. 120/3 = 40 mph. Now to calculate the time it will take to travel 200 miles, divided 200 by 40 mph. 200/40 = 5

Step-by-step explanation:
Rate of change = (f(-4)-f(0))/-4
Plug in the numbers
f(-4) = 10 - (3/4)(-4) = 10-3 = 7
f(0) = 10 - (3/4)(0) = 10
Plug back into first equation
(7-10) = 3/4

Answer:
-3/4
Step-by-step explanation:
The given function is a linear function with a slope of -3/4. (The slope is the coefficient of x.) The slope is the rate of change. For a linear function, the slope is the same everywhere. That is, the "average rate of change" and the "rate of change" and the "slope" are all the same value.
Here, the average rate of change is -3/4.
__
Alternate solution
You can compute the average rate of change using the formula ...
average rate of change = (f(x2) -f(x1))/(x2 -x1)
For x1 = -4 and x2 = 0, we need to know the function values:
f(-4) = 10 -(3/4)(-4) = 13
f(0) = 10 -(3/4)(0) = 10
So, the average rate of change formula gives ...
average rate of change = (10 -13)/(0 -(-4)) = -3/4
The average rate of change is -3/4.

Step-by-step explanation:
You replace the x with 10, and the y with 60 and answer normally
13(30) = 130

The total price of apples (y) at an orchard can be calculated with the equation y=1.25x+5, where x is the number of pounds of apples picked. What does the slope represent?
Given:
The total price of apples (y) at an orchard can be calculated with the equation
[tex]y=1.25x+5[/tex]
where, x is the number of pounds of apples picked.
To find:
The interpretation of slope for the given situation.
Solution:
The slope intercept form is
[tex]y=mx+b[/tex] ...(i)
where, m is slope and b is y-intercept.
We have,
[tex]y=1.25x+5[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]m=1.25, b=5[/tex]
Slope = 1.25.
We know that, y is total price of x pounds of apples picked and slope is change in y with respect to x.
Therefore, the slope of the given equation is 1.25 and it means the price increased by 1.25 for each additional pounds of apples.

PLS HELP ME:(( i don’t understand this, i can’t afford to get anything wrong right now!
Answer:
The answer is B.
Step-by-step explanation:
The answer's B because If you look at the box and whisker plot the median is 6. That is true because 5 + 7 = 12 and divided by 2 would equal 6 therefore the median is 6. Also the 1st oulier is 1 and the 2nd outlier is 11. There you go hope you understand it.....

1. do the stuff in the parantathes (nothing)
2. break parenthates ( now it should look like this 7a-b*7a+b)
3. add the same thing together (7a's cancel each other out)
4. now your left with (-b+b now they cancel each other out)

The price of a dress was reduce from $20 to $12. By what percentage was the price of the dress reduced?
Answer:
40%
Step-by-step explanation:
12$ out of the original 20$ = 12/20
12/20 = .6 (60%)
1=100%
if 12/20 = 60% then 100% - 60% = 40%
$20-40% is $12

Step-by-step explanation:
Given the function f(x) = -3x2 + 4x + 6, find f(2) and f(3). Choose the statement that is true concerning these two values.
The value of f(2) is the same as the value of f(3).
The value of f(2) cannot be compared to the value of f(3).
The value of f(2) is smaller than the value of f(3).
The value of f(2) is larger than the value of f(3).
Answer:
The value of f(2) is larger than the value of f(3).
Step-by-step explanation:
[tex]f(x) = -3x^{2} +4x+6\\f(2) = -3*2^{2} +4*2+6=2\\f(3) = -3*3^{2} +4*3+6=-9\\[/tex]

which statements about the trend line in item 3 are true? select all that apply.
a. the slope is the cost of one book
b. the slope is the cost if Hana's lunch
c. the y-intercept is the cost of one book
d. the y-intercept is the most if Hana's lunch
Answer: A and D
Step-by-step explanation:
I took the test online and the answer is A and D the y intercept is the cost of her lunch and the slope is the cost of one book
The true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given:
as, from the graph the slope tells us about the cost of one book.
Now, From the graph if we talk about y- axis then we can see that the y- axis tells us about cost if Hana's lunch.
Hence, the true statements are the slope is the cost of one book and the y-intercept is the cost if Hana's lunch.
