Answer:
$30
Step-by-step explanation:
$38-$8=$30
Answer: 30
Since Eugene just got $8, and the question is asking how much he had before that, we have to subtract 8 from 38.
38 - 8 = 30
So, the answer is 30. Hope this helps!

- 10x - y = 27
- 4x - y = 9
Find the solution of the system equation.
Step-by-step explanation:
-10x - y = 27 ...1
-4x - y = 9 ...2
...1 - ...2
-10x -y - (-4x - y) = 27 - 9
-10x -y +4x + y = 18
-10x + 4x = 18
-6x = 18
x = 18/(-6)
= -3
Answer:
x = - 3, y = 3
Step-by-step explanation:
Given the 2 equations
- 10x - y = 27 → (1)
- 4x - y = 9 → (2)
Multiplying (1) by - 1 and adding to (2) eliminates the term in y
10x + y = - 27 → (3)
Add (2) and (3) term by term to eliminate y
6x = - 18 ( divide both sides by 6 )
x = - 3
Substitute x = - 3 into either of the 2 equations and solve for y
Substituting into (2)
- 4(- 3) - y = 9
12 - y = 9 ( subtract 12 from both sides )
- y = - 3 ( multiply both sides by - 1 )
y = 3
Solution is x = - 3, y = 3
Find the slope of (1,8) and (3, 12)
Answer: 4/2
Step-by-step explanation:
subtract 12-8 , it would be 4
then 3-1 , it would be 2
The slope of (1,8) and (3,12) is 2 and this can be determined by using two-point slope formula and also using the given data.
Given :
Points -- (1,8) and (3,12)
The following steps can be used in order to determine the slope of (1,8) and (3,12):
Step 1 - The two-point slope formula can be used in order to determine the slope of (1,8) and (3,12).
Step 2 - The two-point slope formula is given by:
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Step 3 - Now, substitute the values of the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] in the above formula.
[tex]\rm m =\dfrac{12-8}{3-1}[/tex]
m = 2

Which statement describes the transformation that would map figure QRST to figure Q'R'S'T' on the grid above?
(x,y) → (-x,y - 9) is the correct transformation for the given graph so option (A) will be correct.
What is the transformation of a graph?Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.
Reflection is a mirror image of a graph about any axis.
If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).
Given the quadrilateral QRST not if we look at Q'R'S'T' it is 9 units downward so it means there will be 9 units decrement in y units.
So y → y - 9
Now,
Q'R'S'T' is as far from the x-axis as QRST but on the negative x-axis.
So,
x → -x
Hence "(x,y) → (-x,y - 9) is the correct transformation for the given graph".

You are a travel agent. A customer requires a hotel
reservation for four nights. You are considering two
hotels. The first usually charges $168 per night, including
all taxes and fees, but will give a discount of $40 per
night. The second charges $185 per night, including all
taxes and fees, and will offer one night for free.
O $504
O $512
O $555
$580

The bottom of Paul's fish tank is a square shape that has an area of 64 square inches.
Paul wants to buy a decorative square plate to put in the bottom of the tank. What
should be the length of the sides of the plate that Paul buys?
Answer:
Divide the area by 4 which makes 16 so that means that Paul should buy 16 inch plates.
Step-by-step explanation:
The length of the sides of the plate that Paul buys is 16 inches.
Given that,
The area of the square shape is 64 square inches.And, we know that the square contains 4 sides.Based on the above information, the calculation is as follows:
[tex]= \frac{64}{4}[/tex]
= 16
Therefore we can conclude that the length of the sides of the plate that Paul buys is 16 inches.

Suppose Jasmine drives from home to the office in 20 minutes. Use this information and part (b) to write an equation.
4.Jasmine drives every morning to her office that is 12 miles from her home.
* What is Jasmine's driving speed in mph?
Solve the equation you created in part (c) to answer the question.
Answer:
1. Her time in minutes is 720/s minutes
2. Given her time to be 20 minutes, her speed is 36 mph
Step-by-step explanation:
Mathematically,
Distance = speed * time
In this question, we want to calculate time;
So time = distance/speed
times = 12 miles/s mph = 12/s hours
Now we want our answer in minutes
Kindly recall that 60 minutes = 1 hour
So 12/s hours will be 12/s * 60 = 720/s minutes
2. Since she drives from home to the office in in 20 minutes, we want to calculate her speed in mph
From the time calculated above i.e 720/s
We can equate 20 = 720/s
20s = 720
s = 720/20
s = 36 mph
