It moves, flips, or changes a shape to create a new shape.
A(-2,1), B(1,0), and CC –3, 2). Draw the image after a dilation with a scale factor of 2
Answer:
Please check the attached figure.
The red-colored triangle represents the image triangle after a dilation with a scale factor of 2.Step-by-step explanation:
Given the vertices
A(-2, 1)B(1, 0)C(-3, 2)A rule of dilation by a scale factor of 2
(x, y) → (2x, 2y)
As the scale factor > 1, thus the image will be enlarged.
The vertices of the image after dilation by a scale factor of 2 are:
(x, y) → (2x, 2y)
A(-2, 1) → A'(-4, 2)
B(1, 0) → B' (2, 0)
C(-3, 2) → C' (-6, 4)

a linear function contains the following points.
what are the slope and the y- intercept?
Answer:
Since
The slope is 1/4.The y-intercept is (0, 3)Therefore, option (A) is true.
Step-by-step explanation:
Determining the slope
Given the points
(-8, 1)(0, 3)Finding the slope between the points (-8, 1) and (0, 3)
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-8,\:1\right),\:\left(x_2,\:y_2\right)=\left(0,\:3\right)[/tex]
[tex]m=\frac{3-1}{0-\left(-8\right)}[/tex]
[tex]m=\frac{1}{4}[/tex]
Thus, the slope is 1/4.
Determining the y-intercept
We know that the value of y-intercept can be computed by setting the value x= 0 and determining the corresponding value of y.
From the table, it is clear that
at x=0, y = 3
Thus, the y-intercept is (0, 3)
Since
The slope is 1/4.The y-intercept is (0, 3)Therefore, option (A) is true.
What is the solution of the system of equations?
y=6x^2+ 3x – 11
y= 3x - 5
A. (x,y) = (-2,1) and (x,y) =(-8,-1)
B. (x,y) = (1,-1)
C. (x,y) =(-1,-8)
D. (x,y) = (1,-2) and (x,y) =(-1,-8)
Answer:
b
Step-by-step explanation:
Answer:
We can use the FOIL method to expand these two binomials. FOIL stands for First, Outer, Inner, Last. F: The First means that we multiply the first terms of each binomial together. In this case, that would be x · y = xy. O: The Outer means that we multiply the outer terms, or the first term of the first binomial and the second term of the last binomial, together. In this case, that would be x · 8 = 8x. I: The Inner means that we multiply the inner terms, or the second term of the first binomial and the first term of the second binomial, together. In this case, that would be (-1) · y = -y. L: The Last means that we multiply the last terms of each binomial together. In this case, that would be (-1) · 8 = -8. Adding all of these together, we get xy + 8x - y - 8 as our final answer.

B.

C.

The mean of the set is [tex]\frac{5}{18}[/tex].
What is mean?'The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.'
According to the given problem,
Total of the given numbers = [tex]\frac{1}{3} +\frac{1}{12} +\frac{1}{3} +\frac{1}{4} +\frac{7}{18}[/tex]
= [tex]\frac{12+3+12+9+14}{36}[/tex]
= [tex]\frac{50}{36}[/tex]
Now, number of values = 5
Mean = [tex]\frac{Sum of the values}{Number of values}[/tex]
⇒ Mean = [tex]\frac{\frac{50}{36} }{5}[/tex]
⇒ Mean = [tex]\frac{5}{18}[/tex]
Hence, we can conclude that the mean of the following set is [tex]\frac{5}{18}[/tex].

**ALSO DON’T ANSWER IF YOU WONT SHOW YOUR STEPS ****
Answer:
y intercept is (0,5)
x intercept is (5,0)
Step-by-step explanation:
re arange the equation to y = -x + 5.
To find the y intercept, you plug in 0 for x and find out what the value of y is. To find the x intercept, you plug in 0 for y and find the value of x.
A rectangle plates has area of 30 1/16 square inches. If the width of the plates is 4 5/8 inches, what is it length in inches?
Answer:
[tex]l=6\dfrac{1}{2} \ \text{inches}[/tex]
Step-by-step explanation:
Given that,
The width of the rectangular plate = [tex]4\dfrac{5}{8}=\dfrac{37}{8}\ \text{inches}[/tex]
The area of a rectangular plate = [tex]30\dfrac{1}{16}=30.0625\ in^2[/tex]
We know that, the area of a rectangular is given by :
A = lb, l is the length
[tex]l=\dfrac{A}{b}\\\\l=\dfrac{30.0625}{\dfrac{37}{8}}\\\\l=6.5\ \text{inches}[/tex]
or
[tex]l=\dfrac{13}{2}\ \text{inches}\\\\=6\dfrac{1}{2} \ \text{inches}[/tex]
So, the length of the rectangular plate is [tex]6\dfrac{1}{2} \ \text{inches}[/tex]

Now, we will add the fractions.
[tex]\frac{1}{4}+\frac{2}{4}[/tex] = [tex]\frac{3}{4}[/tex]
[tex]3+1[/tex] = [tex]4[/tex]
[tex]4+\frac{3}{4}[/tex] = [tex]4\ \frac{3}{4}[/tex]

Complete question :
grocery store was having a sale. Darla had $15 in her wallet. She planned to purchase 2 gallons of fruit juice, 3 bags of chips, and a box of cupcakes. Item Sale Price Gallon of fruit juice $3.50 for first gallon, 50% off the second gallon Bag of Chips 2 for $5 or $2.65 each Box of cupcakes $4.79 How much would Darla pay for her groceries before tax? Show your work.
Answer:
$17.69
Step-by-step explanation:
Amount had = $15
Items to be purchased = 2 gallons of fruit juice, 3 bags of chips, and a box of cupcakes.
First gallon of juice = $3.50
Second gallon = 0.5 * 3.50 = $1.75
3 Bags of chips = $2.65 + $5 = $7.65
A box of cupcake = $4.79
Total cost before tax = $(3.50 + 1.75 + 7.65 + 4.79)
= $17.69
