HELP QUICK!!! What is the percent of change when a savings account goes from $128 to $112?
Answer:
The percent of change is –12.5%.
Answer:
-800%
Step-by-step explanation:
1. you have to do 128-112 and you get 16.
2. you then take 128 and divide by 16 and you should get 8.
3. you take 8 and multiply it by 100 and you should get 800.
4. and since you are going from 128 to 112 you are decreasing so the final number will be negative.
hope this helped!

points (9, 6) and (3, 10)
Answer:
slope = - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
Parallel lines have equal slopes
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (9, 6) and (x₂, y₂ ) = (3, 10)
m = [tex]\frac{10-6}{3-9}[/tex] = [tex]\frac{4}{-6}[/tex] = - [tex]\frac{2}{3}[/tex] ← slope of parallel line
Answer:
Step-by-step explanation:

What is the corresponding angle or side?
Answer:
Number 1 would be FK
Number 2 would be SQR
Answer:
1) FK
2) SQR
Step-by-step explanation:
In congruence statements such as these, each letter's position corresponds to the letter in the same position on the other side.
For example, in 1, MK corresponds to FK because M and F are in the same position and K is in the same position as itself (reflexive property).
In 2, FHG corresponds to SQR because each letter is in the same position in the given congruence statement.

ΔABC is reflected across the x-axis and then translated 4 units up to create ΔA′B′C′. What are the coordinates of the vertices of ΔA′B′C′ ?
A.

B.
A′(3, -3), B′(1, -1), C′(2, -3)
C.
A′(3, -5), B′(1, -7), C′(3, -5)
D.
A′(-3, 3), B′(-1, 1), C′(-2, -3)
The missing figure is attached down
Answer:
The coordinates of the vertices of Δ A'B'C' are A' (-3, 3), B' (-1, 1), C' (-2, 3) ⇒ A
Step-by-step explanation:
If the point (x, y) reflected across the x-axis , then its image is (x, -y)
If the point (x, y) translated vertically up by k units then its image is (x, y + k)
Let us solve the question using the rules above
∵ The coordinates of Δ ABC are A (-3, 1), B (-1, 3), C = (-2, 1)
∵ Δ ABC reflected across the x-axis at first
→ By using the first rule above change the signs of y coordinates
∴ The image of A = (-3, -1)
∴ The image of B = (-1, -3)
∴ The image of C = (-2, -1)
∵ Then it translated 4 units up
→ Use the second rule above, where k = 4, add each y-coordinates by 4
∴ A' = (-3, -1 + 4)
∴ A' = (-3, 3)
∴ B' = (-1, -3 + 4)
∴ B' = (-1, 1)
∴ C' = (-2, -1 + 4)
∴ C' = (-2, 3)
The coordinates of the vertices of Δ A'B'C' are A' (-3, 3), B' (-1, 1), C' (-2, 3)

Elizabeth withdrew $31 at a time from her bank account and withdrew a total of $279. Fran withdrew $46 at a time from her bank account and withdrew a total of $184. Who made the greater number of withdrawals? [ Select ] made the greater number of withdrawals, because she made [ Select ] withdrawals, while [ Select ] only made [ Select ] withdrawals.
Answer: See explanation
Step-by-step explanation:
Elizabeth withdrew $31 at a time from her bank account and withdrew a total of $279. This means Elizabeth withdrew ($279/$31) = 9 times.
Fran withdrew $46 at a time from her bank account and withdrew a total of $184. This means that Fran withdrew ($184/$46)= 4 times.
Therefore, Elizabeth made the greater number of withdrawals.
[Elizabeth] made the greater number of withdrawals, because she made [9] withdrawals, while [Fran] only made [4] withdrawals.
The height, h, in feet of a kicked soccer ball can be modeled by the function h(t) = -16t2 + 24t + 1, where t is in seconds. On its way down, the ball bounces off the crossbar of the goal, which is 8 feet above the ground. To the nearest tenth, when did the ball hit the cross bar?
Answer:
Step-by-step explanation:
let the height of a kicked soccer ball be expressed by the function:
h(t) = -16t^2 + 24t + 1 where t is in seconds
The ball hit the cross bar when the height is zero
The equation becomes
0 = -16t^2 + 24t + 1
16t^2 - 24t - 1= 0
t = 24±√24²-4(16)(-1)/2(16)
t = 24±√576+64/32
t = 24±√640/32
t = 24+25.298/32
t = 49.298/32
t = 1.54 secs
Hence the ball hit the cross bar at t = 1.6secs (to the nearest tenth)
Questions:
1.Which expression is a factor of n^2+3n-54?
2. The trinomial x^2-14x+49 can be expressed as?
1. (n+9) • (n-6) is the answer
The required, 1. factor of the expression n²+ 3n - 54 = (n + 6)(n - 9), 2. x² - 14x + 49 can be expressed as (x - 7)².
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
3.
To factor the quadratic expression n² + 3n - 54, we need to find two numbers whose product is -54 and whose sum is 3. These numbers are 6 and -9.
Therefore, we can write:
n²+ 3n - 54 = (n + 6)(n - 9)
So the expression (n + 6)(n - 9) is a factor of n² + 3n - 54.
2.
The trinomial x² - 14x + 49 can be expressed as the square of a binomial. Specifically, it is the square of (x - 7):
(x - 7)² = (x - 7)(x - 7) = x² - 14x + 49
Therefore, x² - 14x + 49 can be expressed as (x - 7)².

A plumber charges a $50 fee plus $100 per hour to complete a plumbing job. The total amount spent on a plumbing job can be expressed by the function T(x) = 100x + 50 where x represents the number of hours spent on the plumbing job. The maximum time spent on one job per day is 8 hours. Find a reasonable domain and range for this situation.
Answer:
Between 150 and 800
T is between 150 and 800
Step-by-step explanation:
given information
charges=$50
charges per hour=$100
let the amount of time spent be x
therefore the function for the total amount is
T(x) = 100x + 50
we want to estimate the amount for 1 hour and 8 hours
for 1 hour we have
x=1
T(x) = 100x + 50
T(1) = 100(1)+ 50
T(1) = 150
for 8 hours we have
x=8
T(x) = 100x + 50
T(8) = 100(8)+ 50
T(8) = 800+50
T(8) = 850
the domain is between 150 and 800
what is the slope of the graph of 2x - 5y =20
Answer:
2/5
Step-by-step explanation:
convert to slope-intercept form y=mx+b:
2x - 5y = 20
-5y = 20 -2x
y = -4 (-2/-5)x
y = 2/5x - 4
the slope of the graph represented by 2x - 5y = 20 is 2/5.
To find the slope of the graph represented by the equation 2x - 5y = 20, we need to rearrange the equation into slope-intercept form (y = mx + b), where m is the slope.
Let's start by isolating the term with y:
2x - 5y = 20
-5y = -2x + 20
Next, divide the entire equation by -5 to solve for y:
y = (2/5)x - 4
Comparing the equation with the slope-intercept form, we can determine that the slope (m) is 2/5. Therefore, the slope of the graph represented by 2x - 5y = 20 is 2/5.

Your first job is to babysit a couple of times a week. You charge a flatfee of $10 for transportation back and forth to the house plus $5.50per hour. Let t be the time in hours that you babysit. Write analgebraic expression to define the amount of money you will makefor t hours of work.
Answer:
5.50t + 10
Step-by-step explanation:
Total amount of money made will sum of
transportation fees and money charged for t hours of baby siting
Given
transportation fees of back and forth to the house = $10
also given that
fees of 1 hour babysitting = $5.50
we have to find fee for t hours baby sitting ,
fees of t hours babysitting = fees of 1 hour babysitting*t
fees of t hours babysitting = 5.50t
Total amount of money made = fees of t hours babysitting + transportation fees of back and forth to the house
Total amount of money made = 5.50t + 10
Thus,
algebraic expression to define the amount of money you will make for t hours of work is 5.50t + 10

Alejandro said that the slope of the line in the Example is because for points
2
(2, 140) and (0,0), the rise is 140 and the run is 2. Is Alejandro correct? Explain.
Answer:
Step-by-step explanation:
slope = M = rise/ run
P1=(2,140)
P2=(0,0)
M= (Y2-Y1) / ( X2-X1)
M = 0-140 /0-2
M = -140 / -2
M = 140 / 2
Yes, Alejandro is right
The slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.
Given information-Points of the line are (2,140) and (0,0).
The rise of the line is 140.
The run of the line is 2.
Slope of the line-
Slope of a line describes the steepness and the direction of the line. The slope of of line passing through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be given as,
[tex]m=\dfrac{(y_2-y_1)}{(x_2-x_1)} [/tex]
Thus the slope of the line with points (2,140) and (0,0) is,
[tex]m=\dfrac{(0-140)}{(0-2)} \\ m=\dfrac{140}{2} \\ [/tex]
As the slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.
