Suppose m is the line with equation x=-5, line n is the equation y=1
Here is the complete question:
suppose m is the line with equation x=-5, line n is the line with equation y=1, line g is the line with equation y=x, and line h is the line with equation y=-2. Given A(9,-3), B(6,4), and C(-1,-5), what are the coordinates of the vertices of △A′B′C′ for each reflection?
1. Rx-axis
2. Ry-axis
Answer with step-by-step explanation:
1. When you get the reflecting coordinates along x-axis, the signs of the y coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(9, 3), B(6, -4), and C(-1, 5).
2. When you get the reflecting coordinates along y-axis, the signs of the x coordinates changes. Therefore, A(9,-3), B(6,4), and C(-1,-5) becomes:
A(-9, -3), B(-6, 4), and C(1, -5).

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 95 miles per hour. The westbound train travels at 115 miles per hour. How long will it take for the two trains to be 336 miles apart? Do not do any rounding.
Answer:
It will take 1.6 hours for the two trains to be 336 miles apart.
Step by step explanation:
Given that:
Speed of eastbound train = 95 miles per hour
Speed of westbound train = 115 miles per hour
Combined speed = 95+115 = 210 miles
Distance = 336 miles
[tex]Speed = \frac{Distance}{Time}\\\\210 = \frac{336}{Time}\\\\Time = \frac{336}{210}\\\\Time = 1.6\ hours[/tex]
Hence,
It will take 1.6 hours for the two trains to be 336 miles apart.

Solve the equation below for x:
0.25(x - 13) = 7
Answer:
x=41
Step-by-step explanation:
0.25(x-13)=7
We move all terms to the left:
0.25(x-13)-(7)=0
We multiply parentheses
0.25x-3.25-7=0
We add all the numbers together, and all the variables
0.25x-10.25=0
We move all terms containing x to the left, all other terms to the right
0.25x=10.25
x=10.25/0.25
x=41
The solution to the equation; 0.25(x - 13) = 7 as given is; x = 41
According to the question;
We are required to solve for x in the equation; 0.25(x - 13) = 7The solution to the given equation can be evaluated as follows;
0.25(x - 13) = 70.25x - 3.25 = 70.25x = 10.25x = 41.

You can use a factoring tree to find the prime factorization of 100.
+------ 100----------------+

2 +---50---------+

2 +----25----+
| |
5 5
The prime factorization of 100 is 2 * 2 * 5 * 5, or 2^2 * 5^2, or 5^2 * 2^2
Step-by-step explanation:
2^2 × 5^2 =
(2×2) × (5×5) =
4 × 25 = 100
5^2 × 2^2 =
(5×5) × (2×2) =
25 × 4 = 100
2*2*5*5=100
2 and 5 are the only prime numbers in this question. 2(2)*5(5) doesnt equal 100.
A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.
y=-15x^2+801x-5900
Answer:
The widgets should be sold for $26.7 for the company to make the maximum profit.
Step-by-step explanation:
Given the quadratic equation
[tex]f\left(x\right)=-15x^2+801x-59000[/tex]
As the leading coefficient is (-3), so the graph would be a downward Parabola.
Thus, the maximum profit would be at the vertex.
The selling price 'x' can be determined by determining the x-coordinate of the vertex.
In order to calculate the x-coordinate of the vertex, we can find this by
x = -b/2a
where a = -15 and b = 801
x = -801 / 2(-15)
x = -801/-30
x = 801/30
x = 267/10
x = 26.7
Therefore, the widgets should be sold for $26.7 for the company to make the maximum profit.

the length of a rectangular yard is 4 feet more than the width. the perimeter of the yard is 208 feet. write the equation that represents the perimeter of the yard. let w represent the width. solve the equation. what are the dimensions of the yard?
Answer:
Length = 54 ft.
Width = 50 ft.
Step-by-step explanation:
Let the width of the rectangle be 'w'.
According to question ,
Length = w + 4
Perimeter = 208 ft.
We know that [tex]perimeter = 2(l + w)[/tex] where l = length & w = width
So,
[tex]2(w + 4 + w) = 208[/tex]
[tex] = > 2(2w + 4) = 208[/tex]
[tex] = > 2w + 4 = \frac{208}{2} = 104 [/tex]
[tex] = > 2w = 104 - 4 = 100[/tex]
[tex] = > w = \frac{100}{2} = 50[/tex]
Width = 50 ft.
=> Length = 50 + 4 = 54 ft.

In a series of 4 one day cricket matches, the runs scored by Pakistan and Australia are given below: (06 Marks) Match Pakistan Australia First 102 208 Second 202 192 Third 360 241 Fourth 276 203 Find: (i) What is the average score of Pakistan in one match? (ii) What is the average score of Australia in one match? (iii) Which team performed better?
Step-by-step explanation:
Scores of Australia in all four matches starting from 1st 208, 192, 241, 203 respectively.
Similarly, scores of Pakistan in all four matches starting from 1st 102, 202, 360, 276 respectively.
The avg of Pakistan in one match = (102+202+360+276)/4 = 235
The avg of Australia in one match = (208+192+241+203)/4= 211
Since, the avg score of Pakistan is more than that of Australia, Pakistan performed better.

In triangle △WXY, XY ≅ WX and m∠X=38 Find m∠W
Answer:
[tex]71^{\circ}[/tex]
Step-by-step explanation:
Since two sides of the triangle are equal in length, we can conclude that [tex]\triangle WXY[/tex] is an isosceles triangle. With this information, we can draw an isosceles triangle to find [tex]m\angle W[/tex]. Since the base angles of an isosceles triangle are equal, we can solve for [tex]m\angle W[/tex]:
[tex]38 + m\angle W + m\angle Y = 180[/tex] (Angle sum of triangle is [tex]180^{\circ}[/tex])
[tex]38+2(m\angle W) = 180[/tex] (Base angles of isosceles triangles are equal, there is an image attached to show that [tex]m\angle W[/tex] is one of the base angles)
[tex]2(m\angle W) = 142[/tex]
[tex]m\angle W=71^{\circ}[/tex]
