OC) A (6,2), B (4, 2), C'(10, 6)
OD) A (6,2), B (2, 2), C'(10, 6)
Answer:
d
Step-by-step explanation:
The vertices of image A'B'C' after dilation with a scale factor of 2 about the origin are , A' (6, -2), B' (4,2), and C' (10, 6).
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
ABC has vertices A (3, -1), B (2, 1), and C(5, 3).
Now, After dilation with a scale factor of 2 about the origin the vertices of A', B' and C' are,
A' = 2 × (3, - 1)
= (6, - 2)
B' = 2 × (2, 1)
= (4, 2)
C' = 2 × (5, 3)
= (10, 6)

Answer:
1. 30(8.75) + 11t = 400
2. 12.5 hours
Step-by-step explanation:
1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.
30 hours and $8.75 an hour would be equivalent to 30(8.75)
We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t
Finally, you want to earn a total of $400 a week, which means the sum equals 400
30(8.75) + 11t = 400
2. 30(8.75) = 262.5
400 - 262.5 = 137.5
137.5 / 11 = 12.5

give a numerical example that shows these are not the same expressions. 2(n+5) and 2n+5
Answer:
The two are different expressions because when you distibute, you multiply all terms inside the parenthesis with the 2 in the first one: 2(n+5) = 2n + 10.
2n + 10 ≠ 2n + 5.
Step-by-step explanation:
Answer: Any number that isn’t 1, 2, -1, or -2 I believe.
Step-by-step explanation: In the first expression, you have to distribute the 2, making it equal to 2n + 10, whereas the first is just 2n + 5.
For example if you were to plug the number 3 into this, you would have 2(3+5), which is 2(8) = 16. Versus the other side, 2(3)+5 = 11

For the following square, find the value of x after that Find the length of each side of the square above. Be sure to label your answer and then Find the perimeter of the square above. Make sure to label your answer Please i need help fast or else im gonna fail my class please take this seriously.
Answer:
x = 9 ; 39 in. ; 156 in.
Step-by-step explanation:
Because it is a square, we know that all 4 sides are equal to each other.
This means we can take the two expressions and equal them to each other.
4x + 3 = 3(2x - 5)
4x + 3 = 6x - 15
-2x + 3 = -15
-2x = -18
x = 9
Now that we know the value of x, we can substitute it in to find the side length.
4(9) + 3
36 + 3
39 in.
Therefore, each side of the square is 39 in.
Finally, since we know all the side lengths are 39, we can find the perimeter by adding up all 4 side lengths.
p = 4(39) = 156 in.
Therefore, the perimeter of the square is 156 in.

After swimming 80 feet below the surface of the water, a whale swims up 40 feet. Use a number line to help you create an equation that shows the new location of the whale in relation to the water's surface.
A) The equation is -80 + (-40) = -120. The whale is 120 ft below the water's surface.
B) The equation is -80 + 40 = -40. The whale is 40 ft below the water's surface.
C) The equation is -80 + (-40) = -40. The whale is 40 ft below the water's surface.
D) The equation is -80 + 40 = -120. The whale is 120 ft below the water's surface.
Answer:
the answer is d
Step-by-step explanation:
he swims 80 feet below so thats gonna be a negative number. he then swims up 40 feet so you would be adding . so -80+ 40 = -120
The new location of the whale in relation to the equation of water's surface is -80 + 40 = -120 which correct option (D)
What is equation?
Equation is the defined as mathematical statements that have a minimum of two terms containing variables or numbers are equal.
Whale swims 80 ft below so it be a negative number.
Whale then swims up 40 ft so would be adding .
When the whale is 120 ft below the water's surface so it be a negative number.
-80+ 40 = -120
Hence, the new location of the whale in relation to the equation of water's surface is -80 + 40 = -120

The dimensions of a rectangular monitor screen are such that it's length is 5 in. More than it's width. If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in^2. What are the length and width of the screen?
Given:
Length of a rectangular monitor screen is 5 in more than it's width.
If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².
To find:
The length and width of the screen.
Solution:
Let width of the screen be x inches.
Length of a rectangular monitor screen is 5 in more than it's width. So,
Length of screen = (x+5) inches
Area of screen is
[tex]Area=length\times width[/tex]
[tex]A_1=(x+5)\times x[/tex]
[tex]A_1=x^2+5x\text{ in}^2[/tex]
If the length were doubled and if the width were deceased by 1 in the area would be increased by 170 in².
New length = 2(x+5) inches
New width = (x-1) inches
So, new area is
[tex]A_2=2(x+5)(x-1)[/tex]
[tex]A_2=(2x+10)(x-1)[/tex]
[tex]A_2=2x^2+10x-2x-10[/tex]
[tex]A_2=2x^2+8x-10 \text{ in}^2[/tex]
Area increased by 170 in².
[tex]A_2-A_1=170[/tex]
[tex](2x^2+8x-10)-(x^2+5x)=170[/tex]
[tex]2x^2+8x-10-x^2-5x=170[/tex]
[tex]x^2+3x-10=170[/tex]
Subtract 170 from both sides.
[tex]x^2+3x-10-170=0[/tex]
[tex]x^2+3x-180=0[/tex]
Splitting the middle term, we get
[tex]x^2+15x-12x-180=0[/tex]
[tex]x(x+15)-12(x+15)=0[/tex]
[tex](x+15)(x-12)=0[/tex]
[tex]x=-15,12[/tex]
Width cannot be negative. So, x=12.
Width = 12 inches
Length = 12+5 = 17 inches
Therefore, the length of screen is 17 inches and width is 12 inches.
