Reflect over the x-axis, and then dilate
by a scale factor of 2.
(0, -4) (-2,-4)
(-1,-7) (1, -7)
When reflected over the x-axis and then dilated by a scale factor of 2 the points become (0,8), (-4,8), (-2,14) and (2,14). We need to know about reflection about axes and dilation.
When a point is reflected about the x-axis the x-coordinate remains same but the sign of the y-coordinate changes.When a point is reflected about the y-axis the sign of the x-coordinate changes while the y-coordinate remains same.When a point is reflected about the origin the sign of both the x-coordinate and the y-coordinate changes. Dilating a figure means changing it's shape or size by a scaling factor, the points are multiplied by the corresponding scaling factor. In this question we have to reflect the points about x-axis and dilate by a scale factor of 2. When the points will be reflected about the x-axis the new points will be (0,4) , (-2,4) , (-1,7) and (1,7). Then we have to dilate by a factor of 2, the final points will be (0,8), (-4,8) ,(-2,14) and (2,14).
After reflecting over x-axis and then dilating by a scale factor of 2 the points (0,-4), (-2,-4), (-1,-7) and (1,-7) become (0,8), (-4,8), (-2,14) and (2,14).

12 birds can eat 12 packets of food in 6 minutes. Assuming that all the birds eat at the same rate, how long will it take 9 birds to finish 36 such packets?
Answer:
8 minutes
Step-by-step explanation:
If it takes 12 birds to eat 12 packets of food in 6 minutes that means it takes .5 minutes for 1 bird to eat 1 packet of food. 6÷12=.5
If there is 9 birds to eat 36 packets you first have to multiply the amount of birds times the rate it takes one to eat one packet. 9×.5=4.5 and with this now you know how many packets of food the group of 9 birds can eat per minute. Finally you divide the amount of packets by the amount of packets of food the group of 9 birds can eat per minute. 36÷4.5=8 And that's how they take 8 minutes to eat the 36 packets of food.
suppose two dice are tossed (for each die, it is equally likely that 1,2,3,4,5 or 6 dots will show). what is the probability that the total of the two dice will add up to 7 or 11? group of answer choices 7/36 8/36 10/36 4/36
Correct answer is B. the probability that the total of the two dice will add up to 7 or 11 is 8/36
Suppose two dice are tossed
That means n(s)= 6×6 =36
Let E=Addition of number is 7 or 11
Probability of getting 7 is
N(E)= {(4,3),(3,4),(5,2),(2,5)(6,1)(1,6)}
Probability of get 11 is

how many solutions does the equation y=mx have
Answer:A solution to an equation is the value or values of the variable or variables that make the equation a true statement. Graphically, solutions are the intersections of the graphs of the left side and the right side, or if the equation is written so that one side is zero, we are looking for the x-intercepts (for real solutions.)

First, make sure each equation is in slope-intercept form, where m is your slope and b is your y-intercept (y=mx+b). Next, starting from your y=intercept, graph the slope for each equation.
The goal of graphing the two lines is to find the point where both lines intersect (meet).

Mrs. aviles is planning a fruit-cup party for a class of 18 students and two teachers. She spends $10 for a package of snacks and also takes orders in advance for fruit cups that cost $3 each.
1. describe the domain of the function both in words and numbers?
2. what is the range?
Answer:
domain is x = 3
Thus domain means that for every fruit cup costs $3
Range is f(20) = 60
Step-by-step explanation:
We are given;
Total students for the fruit cup party = 18
Total teachers for the fruit cup party = 2
Cost of each fruit cup =$ 3
Delivery charge = $ 10
Now, the total number of people attending the party = Total number of students + Total number of teachers
Thus;
Total number of people attending party = 18 + 2 = 20
Since cost of each fruit cup is $3.
Thus, for 20 fruit cups, the function is;
f(x) = 20x where x is cost of each fruit cup.
It means the cost of 20 fruit cups = $3 × 20 = $60
Thus, domain is x = 3
Thus domain means that for every fruit cup costs $3
Range is f(20) = 60

Answer:
y = -x + 8
Step-by-step explanation:
The equation can be written as;
y = mx + b
where b is the y-intercept
From the diagram , b= 8
y = mx + 8
To get m, substitute (8,0 ) into the equation
0 = 8x + 8
x = -8/8
x = -1
So the full equation is;
y = -x + 8
Write equations for the vertical and horizontal lines passing through the point (−6, -2)
vertical line:
horizontal line:
Answer:
Vertical line: x = -6
Horizontal line y = -2
Step-by-step explanation:
A vertical line will have a constant x value for all values of y so it will be of the form x = k where k is a constant. Since it passes through (-6,-2), where the x value is -6, we get the equation x = -6
A horizontal line will have a constant y value for all values of x so it will be of the form y = k where k is a constant. Since it passes through (-6,-2), where the y value is -2, we get the equation y = -2
The attached graph shows the two lines and the point (-6, -2)

Please help! State which property of equality justifies the statement:
If VR+TY=EN+TY, then VR=EN.
The subtraction property of equality is the property of equality that validates the statement "If VR + TY = EN + TY, then VR = EN." This assertion is expressed in the form of "If VR + TY = EN + TY, then VR = EN."
How can one identify whether a feature of equality warrants the assertion being made?VR + TY = EN + TY
Therefore
VR=EN
The following equation results from using the equality property's subtraction property.
Thus, we have
VR + TY - TY = EN + TY - TY
Determine the difference in the aforementioned equation.
Thus, we have
VR = EN
Hence, If VR + TY = EN + TY, then VR = EN is supported by the equality's subtraction feature, which is stated as "If VR + TY = EN + TY, then VR = EN."

Type the answer into the box below.
b. What is the area of this figure, to the nearest square unit?
Type your answer in the box below.
Answer:
i need this tooo
Step-by-step explanation:
The perimeter of this figure, to the nearest unit, is 37.9 units and the area of this figure, to the nearest square unit is 153.54 square units.
What is a square?It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.
We have a figure shown in the picture made with squares and circles.
To find the perimeter of the figure.
First, calculate the circumference of the circle portion.
The circumference of the 1/4 circle = (1/4)2πr
The radius of the circle r = 5 units
The circumference of the 1/4 circle = (1/4)2π(5)
The circumference of the 1/4 circle = 7.85 units
The perimeter of the figure = 10 + 5 +7.85 + 5 + 10
The perimeter of the figure = 37.85 units ≈ 37.9 units
The area of the figure = area of the square - an area of the square(5×5) +
area of the 1/4 circle
The area of the figure = 10×10 - 5×5 + π(5)²
The area of the figure = 100 - 25 + 78.53
The area of the figure = 153.54 square units
Thus, the perimeter of this figure, to the nearest unit is 37.9 units and the area of this figure, to the nearest square unit is 153.54 square units.

the sum of three angles of a triangle adds up to 180 degrees. In this problem, you are given two angles.
x+(2x+15)+the measure of angle Q should equal 180.
Since everything is addition, the parenthesis can be removed.
x+2x+15+Q=180. This can then be simplified to 2x+15+Q=180. Subtract 15 from both sides to get 2x+Q=165. Divide both sides by two to get the x by itself. x+Q=82.5.
