Answer:
A) 1/2x-6=-2x-1
B) x=2
Step-by-step explanation:
question A is asking to set up a system of equations
f(x)=g(x) is the original expression
substitute the equations into this to get 1/2x-6= -2x-1
for b, when you solve this equation you get x=2

She will have to pay back the principal amount of $28,000 plus $728.00 in interest for a total of $28,728.00
Step-by-step explanation:
Interest = principal x interest rate x time period
Interest = 28,000 x .013 x 2
Interest = $728
Total payback amount = principal + interest
Total payback amount = 28000 + 728
Total payback amount = $28,728.00

Sam found a wrecked car that could she could fix. She bought the car for
65% of the original price of $7200. What did she pay for the car? SHOW YOUR WORK
$11,076.92
$4,680
$2,520
$468
Answers
=======================================================
Work Shown:
x% = x/100
65% = 65/100 = 0.65
So 65% in decimal form is 0.65
We use this to find the amount Sam paid for the car
65% of 7200 = 0.65*7200 = 4,680 dollars
--------------
Here's an alternative way to show your work
part/whole = percent/100
x/7200 = 65/100
x/7200 = 0.65
x = 0.65*7200
x = 4680
Ultimately we end up with 0.65*7200 and that's how we lead to the same answer as before. You could cross multiply like so
x/7200 = 65/100
x*100 = 7200*65
100x = 468000
x = 468000/100
x = 4680
So there are many paths to the same answer.

E
Step-by-step explanation:
Since the value of x is 10 and the value of y is -2, we can plug it into the equation for E. -2 = -1/5(10) which makes it -2=-2 which is true.
Step-by-step explanation:
For every 10 units across (0 to 10),
the line decreases by 2 units (0 to -2).
Slope of line
= Rise / Run = (-2) / (10) = -1/5.
Also the y-intercept of the line is 0
as it passes through the origin.
Hence the equation is y = -1/5 x. (E)

Hey there!
The answer to your question is 25,400
To round to the nearest hundred, you would be rounding the last three numbers, since that represents a "hundred". So, we look at those numbers, and we see what hundred it is closer to. "395" is closer to 400 than 200, so your answer would be 25,400.

Step-by-step explanation:
The volume of a hemisphere-topped cylinder is given by the formula ...
V = πr^2(2/3r +h)
where r is the radius and h is the height of the cylindrical section. Of course, the radius is half the diameter, so this silo has a volume of ...
V = π(10 ft)^2(20/3 +40 ft) = 14,660.77 ft^3

Suppose you saved $300 dollars from a summer job. If school starts September 1, can you afford a cell phone data plan of $29.95 per month for the next year(until next September 1)?
Answers
Answer:
No
Step-by-step explanation:
Given that:
Amount saved = $300
Monthly data cost = $29.95
Number of monthly data that can be done from saving :
= amount saved / monthly data cost
= $300 / $29.95
= 10.016694
Hence, saving can only last for 10 months of data subscription.
Hence it can't last till September 1, if the following year, which is about 12 months

The vertices of a triangle are P(2, –8), Q(1, –4), and R(4, –1). Name the vertices of P'Q'R' after a reflection over the x-axis.
Answers
Answer:
The coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)
Step-by-step explanation:
We are given:
The vertices of a triangle are P(2, –8), Q(1, –4), and R(4, –1).
We need to:
Name the vertices of P'Q'R' after a reflection over the x-axis.
Reflection over the x-axis
The rule used for reflection over x-axis
P(x,y)= P'(x,-y)
The coordinates of x-axis remains same, while coordinates of y-axis become negative.
Now, finding coordinates of P'Q'R'
P (2,-8) -> P' (2,8)
Q(1,-4) -> Q' (1,4)
R(4,-1) -> R'(4,1)
So, the coordinates of P'Q'R' are: P' (2,8), Q' (1,4) ,R'(4,1)

Step-by-step explanation:
// Solve equation [2] for the variable y
[2] y = 2x - 8
// Plug this in for variable y in equation [1]
[1] (2x-8) + x = 4
[1] 3x = 12
// Solve equation [1] for the variable x
[1] 3x = 12
[1] x = 4
// By now we know this much :
y = 2x-8
x = 4
// Use the x value to solve for y
y = 2(4)-8 = 0
