Consider the function y = -2x + 1 what is the slope (m)? What is the y intercept (b)? Make a quick graph for the equation
Answer:
Step-by-step explanation:
Start with the slope intercept equation: y=mx+b
y=-2x+1
m=-2 and b=1
Now draw a graph on your paper, place a point at +1 on the Y axis.
Next, solve for y with x=1.
y=-2(1)+1
y=-2+1
y=-1

A car uses data to help determine the color of cars to order for this year. The data displays how many cars were sold the previous year. Each dot
represents 10 cars. Use the dot plot to answer the question.
How many cars were sold that were not white?
A 100
B190
C 19
D 25
The number of cars sold that were not white based on the dot plot is 19
How to determine the number of cars sold that were not whiteFrom the question, we have the following parameters that can be used in our computation:
The dot plot represents the given parameter
From the dot plot, we have the following values represented as follows:
The above parameters means that the following cars are not white cars
So, we have the following representation
Count of red cars = 5Count of black cars = 8Count of silver cars = 1Count of gray cars = 4Count of blue cars = 1When these frequencies are added, we have
Total = 5 + 8 + 1 + 4 + 1
Evaluate the sum
Total = 19
Hence, the number of cars is 19

I have to find angle 1 and angle 3
Answer:
∠1 = 52
∠2 = 128
∠3 = 52
Step-by-step explanation:
∠2 = ∠4 Because of vertical angles
∠1 = ∠3 Because of vertical angles
∠1 + ∠4 = 180 Because of supplementary angles
Here, we are given that ∠4 = 128°
∠4 = ∠2 So ∠2 = 128°
∠1 + ∠4 = 180
∠4 = 128°
∠1 + 128° = 180
==> subtract 128 from both sides
∠1 = 52
∠1 = ∠3
∠1 = 52 meaning that ∠3 = 52
Answer:
m<1 = 52°
m<3 = 52°
m<4 = 128°
Step-by-step explanation:
Given: m<2 = 128°
<1 is supplementary to <2.
m<1 + m<2 = 180°
m<1 + 128° = 180°
m<1 = 52°
Angles 1 and 3 are vertical angles, so they are congruent.
m<3 = 52°
Angles 2 and 4 are vertical angles, so they are congruent.
m<4 = 128°

The values of the unknown angles are ∠1 = 92°, ∠2 = 24°, ∠3 = 64°, ∠4 = 35°, ∠5 = 81°
What are corresponding angles?Corresponding angles are the angles which are formed in matching corners or corresponding corners with the transversal when two parallel lines are intersected by any other line (i.e. the transversal). For example, in the below-given figure, angle p and angle w are the corresponding angles.
∠1 + 88 = 180°( angles on a straight line)
∠1 = 180 - 88 which is 92°
∠3 = 64°( corresponding angles are equal)
∠2 + ∠1 + ∠3 = 180( sum of angles in a triangle)
∠2 + 92° + 64° = 180
∠2 = 180 - 92 - 64
∠2 = 24°
∠4 + 81 + ∠3 = 180 ( angles on a straight line)
∠4 + 81 + 64 = 180
∠4 = 180 - 64 -81
∠4 = 35°
∠5 = 81°( alternate angles are equal)
In conclusion the values of ∠1, ∠2, ∠3, ∠4, ∠5 are 92°, 24°, 64°, 35° and 81° respectively.

One poster has a width of x + 5 inches, and
the other has a width of x + 3 inches. Write an
expression to represent the area of wall that the
posters will cover.
The area that represent the wall the poster will cover is as follows:
x² + 10x + 25x² + 6x + 9What is area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
Therefore, One poster has a width of x + 5 inches, and the other has a width of x + 3 inches.
The expression to represent the area of wall that the posters will cover can be calculated as follows:
area = w²
area of the first poster = (x + 5)² = (x + 5)(x + 5) = x² + 5x + 5x + 25 = x² + 10x + 25
area of the second poster = (x + 3)² = (x +3)(x + 3) = x² + 3x + 3x + 9 = x² + 6x + 9

Examine the following triangle.
Based on the given information, what is the measure of the missing length, w?
Enter your answer as a number.
Answer:
16
Step-by-step explanation:
You must use the Pythagorean theorem to find w. Because you are looking for a leg, you must do a² - b² = c². This translates to 20² - 12² = w². If you enter the numbers into your calculator 20²- 12² = 256. You must then square root 256, and if you input √256 into your calculator you will get your final answer of w = 16.

C) 40-√√3 ft
D) 4√ √/30 ft
The altitude of the balloon found using Pythagorean Theorem is 40·√3 feet, the best correct option is option C)
C) 40·√3 ft
What is the Pythagorean Theorem?The Pythagorean Theorem states that the square of the hypotenuse side of a right triangle is the same as the sum of the square of each of the two legs of the right triangle.
15) The parameters in the question includes;
Horizontal distance of the flag pole from the point the rope is staked down = 40 feet
Length of the rope to which the balloon is secured = 80 feet
Location of the balloon = directly above the flag pole
Therefore, the altitude of the balloon, the length of the rope, and the horizontal distance from the flag pole from the point the rope is staked form a right triangle, with the length of the rope representing the hypotenuse side.
Let h represent the altitude of the flag pole, using Pythagorean Theorem, we get;
80² = 40² + h²
Therefore; h² = 80² - 40² = 4800
The altitude of the balloon, h = √(4800) = 40·√3

Answer:
Step-by-step explanation:
What is the slope of a linear function that passes
between (2, 7) and (5, 12)?
Answer:
5/3 is the slope
Step-by-step explanation:
Use the slope formula
m = y2 - y1/ x2 -x1
Answer:
Slope = 5/3
Step-by-step explanation:
Formula we use,
→ Slope = (y2 - y1)/(x2 - x1)
Now the required slope will be,
→ m = (y2 - y1)/(x2 - x1)
→ m = (12 - 7)/(5 - 2)
→ [ m = 5/3 ]
Hence, required slope is 5/3.

RPQ:______
The value of angle RPQ in the circle is 115°.
What is intersecting chords' theorem?The products of the measurements of the segments of two chords are equal if they intersect in a circle.
When two chords intersect inside a circle, the resulting angle's measure is equal to the product of the lengths of the arcs it intercepts and its vertical angle, divided by two.
Therefore,
∠RPQ = 1 / 2 (arc angle RQ + arc angle SA)
arc angle RQ = 175°
arc angle SA = 55°
Hence,
∠RPQ = 1 / 2 (175 + 55)
∠RPQ = 1 / 2 (230)
∠RPQ = 115°.
Therefore, the angle is 115°.

(a)
How many ways are there for her to distribute the books if they are all the same and no child gets more than one?
(b)
How many ways are there for her to distribute the books if they are different and no child gets more than one? If Charlie gets Green Eggs and Ham and Amanda gets The Cat in the Hat, that is a different distribution from one in which Amanda gets Green Eggs and Ham and Charlie gets The Cat in the Hat.
(c)
How many ways are there for her to distribute the books if they are all the same and there is no restriction on the number of books that can be given to any child?
Answer:
(a) There are 20 ways for her to distribute the books if they are all the same and no child gets more than one. Each of the 20 children can receive one of the five books.
(b) There are 100 ways for her to distribute the books if they are different and no child gets more than one. Each of the 20 children can receive one of the five different books, so there are 5x4x3x2x1 = 100 possible ways for her to distribute the books.
(c) There are 3,628,800 ways for her to distribute the books if they are all the same and there is no restriction on the number of books that can be given to any child. This is because each child can receive any number of books from 0 to 5. Therefore, there are 6x6x6x6x6 = 6^5 = 3,628,800 possible ways for her to distribute the books.

Ratio of tomato plants to lettuce plants = 1:2
Ratio of lettuce plants to cucumber plants = 4:1
Unit rate = $4
Cost of buying 20 copies = $80
What are ratios?
Ratios compare two numbers, usually by dividing them.
If you are comparing one data point (A) to another data point (B), your formula would be A/B. This means you are dividing information A by information B.
For example, if A is five and B is 10, your ratio will be 5/10.
According to the given question:
1) There were 6 boys and 9 girls on the camping trip.
Ratio of boys to girls = 6:9 = 2:3
Ratio of girls to boys = 9:6 = 3:2
2) There are 4 tomato plants, 8 lettuce plants, and 2 cucumber plants in Jill's garden.
Ratio of tomato plants to lettuce plants = 4:8 = 1:2
Ratio of lettuce plants to cucumber plants = 8:2 = 4:1
