E. (3/2,6)
F.(405/19,1601/19)
G.(9,2/3)
H. (7, -3/2)
I. (-6,5)
Step-by-step explanation:
For all of these you are going to solve one of the equations for one of the variables. A lot of them are already solved (One equation has the variable already equal to the other side like B has -2x+8=y.
Then you are going to take that value and substitute it into the other equations.
Once you get the answer for that variable, plug the answer into the other formula and solve.
Finally, check your answers by plugging both variables into the formula.
For example A,
You already have one of the equations solved so you would plug in 3x-11 for y in the bottom equation to get 2x-3(3x-11)=-2
Now distribute and solve 2x-9x+33=-2
2x-9x=-7x and -2-33=-35
Divide both sides by -7
x=5
Now plug 5 into the first equation of y=3x-11 and solve to get y=3(5)-11=15-11=4
Finally, check your work by plugging your numbers into the first equation you worked with 2(5)-3(4)=-2. 10-12=-2. -2=-2
Repeat the steps above for the rest of the problems

Describe the relationship between the number of feet and the number of yards.
Write an expression for the number of yards in f feet.
Find the number of yards in 63 feet.
Answers
Answer:
answer:
1Yarda = 3 feet
y = (1/3) f
y = 21
Step-by-step explanation:
The first thing we should do is see what relationship we have:
Table is feet to yards 3-1
a. Describe the relationship between the number of feet and the number of yards
That is to say:
1Yarda = 3 feet
b. Write an expression for the number of yards in f feet
Let
y = Yard
f = feet
We have the following expression for the conversion:
y = (1/3) f
c. Find the number of yards in 63 feet
For this case we must substitute in the expression found the value of f = 63.
y = (1/3) f
y = (1/3) (63)
y = 21

Answer:
There are 3 feet per yard
# of yards = 3f
189 feet
Step-by-step explanation:
f = feet
y = yard
First Question: Dividing the # of feet by # of yards for one column will always equal 3. So there are 3 feet per 1 yard
Examples: 3/1=3, 6/2=3, 9/3=3 ...
Second Question: To find the number of yards, divide the number of feet by 3. In other words, f/3=y
Third Question: Using the expression f/3=y, there are 21 yards in 63 feet

Mia paddled her canoe from the shore of a lake to an island. She stopped on the island to eat lunch, and then paddled her canoe back to the shore. The graph below shows Mia’s distance, in kilometers, from the shore over time. Based on the graph, which of the following statements is true?
Answers
It took Mia 40 minutes to get to the island, 30 minutes eating lunch, and 30 minutes back.
The speed of Mia on the way back to the shore is greater than speed on the way to the island
What is Speed?Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude
Speed = Distance / Time
Given data ,
Let the speed on the way to the island be S₁
Let the speed on the way back to the shore be S₂
where the Speed = Distance / Time
So , S₁ = ( 3 - 0 ) / ( 40 - 0 )
S₁ = 3/40 km/minutes
S₁ = 0.075 km/minutes
And , S₂ = 0.1 km/minutes
Now , S₂ > S₁
Hence , the speed on the way back to the shore is greater

Answer:
A. (12, -6)
Step-by-step explanation:
When a coordinate gets rotated into the bottom right quadrant of a graph, the x and y coordinates switch places and the y-coordinate becomes negative.
Since the coordinate pair was (6, 12), you would switch the spots of the coordinates to get (12, 6).
After that, make the y-coordinate negative (if the y-coordinate was originally negative, make it positive instead) to get (12, -6).
Therefore, the answer is (12, -6).

Please hurry on an exam The formula for calculating simple interest is I = prt. Which is the equivalent equation solved for r?
StartFraction I Over p t EndFraction = r
StartFraction p t Over I EndFraction = r
I minus p t = r
I + p t = r
Answers
Answer:
r=I/pt
Step-by-step explanation:
I = PRT is the formula for interest, and we need to solve it for R. Since all three of P, R, and T are multiplied, we send things to the other side of the equals through dividing. I = PRT I / P = RT to divide both sides by P I / PT = R to divide both sides by T So I / PT = R (the first choice) is the equation solved for R.

The correct product of 0.60 and 0.40 is 0.24 and the model used to describe is bottom left.
Let us find the product of 0.60 and 0.40.
Multiply the two numbers without considering the decimal point.
0.60 × 0.40
= 0.24
Let us consider the boxes as 1.
Now we have to find the number of boxes which are shaded for 24.

First translate 9 units to the left. Then reflect across the x-axisFigure: First graph
What is the method to determine the transformation of an image?The coordinates of (x, y) following a reflection across the x-axis is (x, -y)
The coordinates following a reflection across the y-axis is (-x, y)
here, we have,
The points of the triangle following the first transformation is therefore;
(4, 4) → (4, -4) → (-4, -4)
(8, 4) → (8, -4) → (-8, -4)
(6, 6) → (6, -6) → (-6, -6)
The image from the first transformation is (-4, -4), (-8, -4), (-6, -6), which
corresponds to the second graph.
The coordinates following a rotation of (x, y) by 180° about the origin is (-x, -y)
A reflection of the point (-x, -y) about the x-axis is (-x, y).
Therefore;
(4, 4) → (-4, -4) → (-4, 4)
(8, 4) → (-8, -4) → (-8, 4)
(6, 6) → (-6, -6) → (-6, 6)
The image from the second transformation is (-4, 4), (-8, 4), (-6, 6), which corresponds to the third graph.
The coordinates following a translation of 9 units to the left is (x - 9, y)
A reflection of the point (x - 9, y) about the x-axis is (x - 9, -y)
Therefore;
(4, 4) → (4 - 9, -4) = (-5, -4)
(8, 4) → (8 - 9, -4) = (-1, -4)
(6, 6) → (6 - 9, -6) → (-3, -6)
The image from the third transformation is (-13, -9), (-1, -4), (-7, -6), which corresponds to the first graph.
