Answer:
D
Step-by-step explanation:
The answer is point D(-2,1).
1. If the point D was moved down 2 units, then its coordinates became (-2,-1).
2. If point (-2,-1) was reflected over the x-axis, then its coordinates became (-2,1).
3. If the point (-2,1) was moved 4 units to the right, then its coordinates became (2,1).
4. If point (2,1) was reflected over y-axis, its coordinates became (-2,1).

given : 2x+8=5x-13; prove x=7
Answer:
True
Step-by-step explanation:
The left side 22 is equal to the right side 22 , which means that the given statement is always true.
Step-by-step explanation:
If we want to prove that x is equal to seven, we should first solve the equation for x so:
2x + 8 = 5x - 13
We should first add 13 on both sides and subtract 2x from both sides:
2x + 8 + 13 - 2x = 5x - 13 + 13 - 2x
21 = 3x
We can then divide both sides by 3 to get:
x = 7

| 2 +r | ≥ 3 (lines are absolute value)
Answer:
r ≤ -5 and r ≥ 1
Step-by-step explanation:
The solution has two parts:
1) that derived from | 2 +r | ≥ 3 when (2 + r) is already positive. Then:
2 + r ≥ 3, or r ≥ 1
and
that derived from | 2 +r | ≥ 3 when (2 + r) is negative. If (2 + r) is negative, then
|(2 + r)| = -(2 + r) = -2 -r, which is ≥ 3. Therefore, -2 -r ≥ 3, or -r ≥ 5. To solve this for r, divide both sides by -1 and reverse the direction of the inequality sign: r ≤ -5

A mountain bike is priced at $413. If the sales tax is 6.5 percent, what is the cost to purchase the mountain bike? Round to the nearest cent if necessary. $26.85 $28.91 $437.78 $439.85At Appliance Market, a salesperson sells a dishwasher for $569. She gets a commission rate of 18 percent. Which expression represents how much she will receive in commission from the sale? 569 (0.18) 569 (0.72) 569 (1.18) 569 minus left-bracket (569) (0.18) right-bracket
Answer: See explanation
Step-by-step explanation:
1. Cost = $413
Sales percent = 6.5%
Cost of bike = $413 + (6.5% × $413)
= $413 + (0.065 × $413)
= $413 + $26.845
= $439.85
2. Cost of dishwasher = $569
Commission rate = 18%
The expression for the commission will be:
= 18% × $569
= 18/100 × $569
= 0.18($569)

While performing a vertical line test on a graph, you notice that the graph intercepts the vertical line twice. Which of the following correctly interprets the result of the test?
Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function.
Because the vertical line intercepted the graph more than once, the graph is of a function, but it is not a relation.
Because the vertical line did intercepted the vertical line exactly twice, the graph is a function and relation.
Because the vertical line intercepted the graph exactly twice, the graph is a function.
Answer:
The correct option is;
Because the vertical line intercepted the graph more than once, the graph is of a relation, but it is not a function
Step-by-step explanation:
Given that a function maps a given value of the input variable, to the output variable, we have that a relation that has two values of the dependent variable, for a given dependent variable is not a function
Therefore, a graph in which at one given value of the input variable, x, there are two values of the output variable y is not a graph of a function
With the vertical line test, if a vertical line drawn at any suitable location on the graph, intercepts the graph at more than two points, then the relationship shown on the graph is not a function.
Answer:
a
Step-by-step explanation:
A continuous function graph shows unbroken lines or curves or part of a line or curve.

Given that,
A triangle is shown in the image.
Apply the concept of the triangle that states,
The sum of two opposite interior angles in a triangle is equal to the measure of the exterior angle.
Hence we get;
y° + 20° = 130°
Subtract both sides by 20,
y = 130° - 20°°
y = 110°
Therefore, option 3 is true.

The ratio of length to width of a rectangular swimming pool is 4 : 5. If the width of the swimming pool is 25 meters, find the perimeter of the pool.
Answer:
20 hrs
Step-by-step explanation:
20 hours: The volume of the pool is (length) × (width) × (height), or 30×10×2=600 cubic meters. Use a standard work equation, RT= W, where W represents the total work of 600 m

.
0.5×t=600
t=1200 minutes
Convert this time to hours by dividing by 60: 1200÷60=20 hours.
Alternatively, you could convert first:
hr
0.5m

×60min=

Next, use the standard work equation:

t = 20 hours
The perimeter of the rectangular pool would be 90 meters and the length of the pool is 20 meters.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that the ratio of length to width of a rectangular swimming pool is 4 : 5.
Let the length of rectangular swimming pool would be 4x
And the width of rectangular swimming pool would be 5x
Since the width of the swimming pool is 25 meters.
So 5x = 25 ⇒ x = 25/5 = 5
So the length rectangular swimming pool would be 4(5) = 20 meters.
The perimeter of the pool = 2 [ length + width ]
The perimeter of the pool = 2 [ 20 + 25]
The perimeter of the pool = 2 (45)
The perimeter of the pool = 90 meters

School was starting and James had $300 to spend on clothes. He bought a pair of shoes for$62.50, 3 shirts for $17.25 each, and 5 pairs of jeans at $27.75 each. How much change will James get back? *
Answer:
$47
Step-by-step explanation:
Multiply the quantities of each by the prices, then add it all together to find total spent. Subtract total spent from what he has to spend to find the change:
3 shirts x 17.25 = 51.75
5 jeans x 27.75 = 138.75
Total pent : 62.50 + 51.75 + 138.75 = $253.00
Change : 300 - 253 = $47.00

Step-by-step explanation:
A. Circumference is 2πr (or dπ), so we plug in 14 for r
this leaves us with 2π14, in which the 2 and 14 can multiply, so we get 28π

f(x)=3x-1
Answer:
Given f(x)=32
So we can substitute 32 in place of 'x'
So, f(x)=3x-1
= f(x)=3(32)-1
= f(x)=96-1
= f(x)=95
f(x)=3x-1 = 95

Answer:
1.) 3/4
2.) 44/5 or 8 4/5
3.) 17/6 or 2 5/6
Step-by-step explanation:
1.) 5/16 ÷ 5/12
To divide a fraction by another fraction, reciprocate (put the numerator to denominator and vice versa) the divisor then change the sign to multiplication:
5/16 × 12/5
5 × 12 / 16 × 5
Cancel out 5 since both numerator and denominator has it:
12 / 16
Divide both by 4:
12 ÷ 4 / 16 ÷ 4
3/4
2.) 3 1/5 • 2 3/4
You have to convert the fractions first to improper fractions by multiplying the denominator to the whole number then adding the numerator to the product:
3 1/5 = 3×5 + 1 = 16/5
2 3/4 = 2 × 4 + 3 = 11/4
Now you can multiply the numerator to numerator then denominator to denominator:
Since 16 is a factor of 4, you can cancel it out, which leaves 4:
16 / 5 × 11/4
4 × 11 / 5 × 1
44/ 5
3.) 6 3/8 ÷ 2 1/4
Convert to improper fraction:
6 3/8 = 6× 8 + 3 = 51/8
2 1/4 = 4 × 2 + 1 = 9/4
(51 × 4)/ (9×8)
51 × 1/ 9× 2

A patient with high blood pressure who weighs 226 pounds is put on a diet to lose 26 pounds in 3 months. The patient loses 8 3 4 pounds the first month and 11 5 8 pounds the second month. How much weight must be lost the third month for the goal to be achieved?
Given :
A patient with high blood pressure who weighs 226 pounds is put on a diet to lose 26 pounds in 3 months. The patient loses 8 3/4 pounds the first month and 11 5/8 pounds the second month.
To Find :
How much weight must be lost the third month for the goal to be achieved.
Solution :
Let, weight lose in third month is x.
So, 8 3/4 + 11 5/8 + x = 26
[tex]\dfrac{32+3}{4}+\dfrac{88+5}{8}+x=26\\\\x = 26 - ( \dfrac{35}{4}+\dfrac{93}{8})\\\\x=5.625\ pounds[/tex]
Therefore, weight lose in third month is 5.625 pounds.
Hence, this is the required solution.
