Answer:
The equation of line that passes through point (2,-1) and has a slope of -3 is [tex]\mathbf{y=-3x+5}[/tex]
Option A is correct.
Step-by-step explanation:
We need to write equation of line that passes through point (2,-1) and has a slope of -3
The equation is written in slope-intercept form: [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
We are given slope: m = -3
We need to find y-intercept (b)
Using the point (2,-1) and slope m=-3, we can find y-intercept
[tex]y=mx+b\\-1=-3(2)+b\\-1=-6+b\\b=-1+6\\b=5[/tex]
So, we get y-intercept b = 5
Now, the required equation having slope m =-3 and y-intercept b = 5 will be:
[tex]y=mx+b\\y=-3x+5[/tex]
So, the equation of line that passes through point (2,-1) and has a slope of -3 is [tex]\mathbf{y=-3x+5}[/tex]
Option A is correct.

Answer:
AE = CE = 23; BE = DE = 20
Step-by-step explanation:
Put the values of the variables in their place and do the arithmetic.
AE = 2u+5 = 2(9) +5 = 23
BE = 6v-1 = 6(3.5) -1 = 20
CE = 3u-4 = 3(9) -4 = 23
DE = 8v-8 = 8(3.5) -8 = 20
The diagonals cross at their midpoints, so the quadrilateral is a parallelogram.

1.How do you dilate a figure on the coordinate plane?
2. What is scale factor?
3. What are the properties of similar figures (what do they have congruent and/or proportional)?
Answers
Answer:
1. To dilate something in the coordinate plane, multiply each coordinate by the scale factor. This is called mapping. For any dilation the mapping will be \begin{align*}(x, y) \rightarrow (kx, ky)\end{align*}. In this Concept, the center of dilation will always be the origin, unless otherwise stated.
2. When using State Plane coordinates the scale factors, also known as the K factors, are ratios that can be used as multipliers to convert ellipsoidal lengths, also known as geodetic distances, to lengths on the map projection surface, also known as grid distances, and vice versa.
3.Similar figures have the same shape (but not necessarily the same size) and the following properties: Corresponding sides are proportional. That is, the ratios of the corresponding sides are equal. Corresponding angles are equal.

f) One number is 78 more than
another. If you add 12 to tbe
smaller number, the result is 50.
What is the larger number?
Answers
Answer:
The larger number = 116
Step-by-step explanation:
Let the smaller number = x
Given that one number is 78 more than another, so
The larger number = x+78
Given that if we add 12 to the smaller number, the result is 50, so
[tex]x+12=50[/tex]
subtract 12 from both sides
[tex]x+12-12=50-12[/tex]
Simplify
[tex]x=38[/tex]
Therefore,
The smaller number = 38The larger number = x+78 = 38+78 = 116Thus, the larger number = 116

D. 100°
Answers
Answer:
D. 100
Step-by-step explanation:
Answer:
100°
Step-by-step explanation:
Since ΔABC ≅ Δ DEF, and the sum of the measures of the interior angles of a triangle is 180°, subtract the given angle measurements from 180°.
∠A ≅ ∠D, ∠B ≅ ∠E, ∠C ≅ ∠F (The vertices are written in this order because they are corresponding angles.)
180° - 55° = 125° - 25° = 100°
∠C is 100°

Movie tickets cost $6 for adults and $2 for children under the age of 12. If 175 movie tickets were sold with cash receipts of $750, how many children’s tickets were sold?
Answers
Answer:
75 child tickets and 100 adult tickets were sold.
Step-by-step explanation:
Given that adult tickets cost $ 6 and children's tickets cost $ 2, knowing that 175 tickets were sold for $ 750, to determine how many child tickets were sold the following calculation must be performed:
2 x 175 = 350
750 - 350 = 400
6 - 2 = 4
400/4 = 100
175 - 100 = 75
100 x 6 = 600
75 x 2 = 150
Therefore, 75 child tickets and 100 adult tickets were sold.

200 minutes
The rate will be 8.33 minutes per picture. Then the number of minutes will be 200 minutes.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Clayton draws 3 pictures in 25 minutes. Then the rate is given as,
Rate = 25 / 3
Rate = 8.33 minutes per picture
He drew 24 pictures this week. Then the number of minutes is calculated as,
⇒ 24 x 8.33
⇒ 200 minutes
The rate will be 8.33 minutes per picture. Then the number of minutes will be 200 minutes.

First, we see a rectangle shape with little squares in it. The length is 5 and the width is 4. If we multiply them, we get 20 square units. However, we will use the 20 to solve the question. Also, we see that there are only 3 squares.
3/20
Let's divide the fraction. 3 / 20 is 0.15. We result with 0.15. Now, we multiply the decimal by 100 to get a percent; we are converting from decimal to percent. As a result, we get 15% as our answer.
3/20 = 0.15 x 100 = 15%
