Answer: D
Step-by-step explanation: Notice that if you multiply both sides of the equation of y2 = m (x2 - x1) + y1 by X2 - X1.
This gives you m(X2 - X1) = Y2 - Y1.
Then add Y1 to both sides to get m(X2 - X1) + Y1 = Y2.
This slope would be equivalent to the usual slope formula.

3x +45 = 90
3x + 45-45 = 90 -45
3x = 45
Divide both sides by 3
3x/3 = 45/3
x = 15
#20 supplementary
2x + 3x + 25 = 180
5x + 25 = 180
5x + 25 - 25 = 180 -25
5x = 155
Divide both sides by 5
5x/5 = 155/5
x = 31
#15 - vertical
4x - 25 = 75
4x - 25 + 25 = 75 + 25
4x = 100
Divide both sides by 4
4x/4 = 100/4
x = 25

4x + 2x = 90

2x -20 = 90
2x -20 + 20 =90 +20
2x = 110
Divide both sides by 2
2x / 2 = 110/2
x = 55
Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

We'll use 3.14 for pi.
Can A:
Diameter = 10
Radius = 5
Height = 10.5
Because the radius is half that of the diameter.
C = 3.14 * (5^2) * 10.5 = 824.25
Can A Volume = 824.25
Can B:
Height = 11
Radius = 3.75
V = 3.14 * (3.75) * 11 = 129.525
Can B Volume = 129.525
Can A is bigger than Can B.

A cylindrical can of vegetables has a label wrapped around the outside, touching end to end. The only parts of the can not covered by the label are the circular top and bottom of the can. If the area of the label is 88π square inches and the radius of the can is 2 inches, what is the height of the can?
22 inches
11 inches
8 inches
4 inches
Answers
Answer:
22 inches
Step-by-step explanation:
The area of the label is the lateral area of the cylinder, which is given by the formula:
A = 2πrh
where r is the radius and h is the height of the cylinder.
We are given that the area of the label is 88π square inches and the radius is 2 inches. Substituting these values into the formula, we get:
88π = 2π(2)(h)
Simplifying, we get:
88 = 4h
Dividing both sides by 4, we get:
h = 22
Therefore, the height of the can is 22 inches. Answer: 22 inches.
Answer:
22 inches

A rational number is a number that can be represented as a/b where a and b are integers and b is not equal to 0.
Since -0.8 is an integer or decimal from above, -0.8 is also a rational
An irrational number is a number that cannot be expressed as a ratio between two integers and is not an imaginary number.
Answer:
It is a rational number

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

Answer:
\(x=\frac{1}{r} +1\)
Step-by-step explanation:
\(r=\frac{1}{x-1}\)
\(r(x-1)=1\)
\(x-1=\frac{1}{r}\)
\(x=\frac{1}{r} +1\)
Answer:
\(x=\dfrac{1+r}{r}\)
Step-by-step explanation:
Given equation:
\(r=\dfrac{1}{(x-1)}\)
Multiply both sides by (x - 1):
\(\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)\)
\(\implies r(x-1)=1\)
Expand the brackets:
\(\implies rx-r=1\)
Add r to both sides:
\(\implies rx-r+r=1+r\)
\(\implies rx=1+r\)
Divide both sides by r:
\(\implies \dfrac{rx}{r}=\dfrac{1+r}{r}\)
\(\implies x=\dfrac{1+r}{r}\)

c. (2, -4) and (-18, 36)
Explanation:
Step 1 - Simply the first equation and substitute the value of y into the second equation
y = 1/4x^2 + 2x - 9
y = x^2/ 4 + 2x - 9
x^2/ 4 + 2x - 9 = -x^2/ 4 - 6x + 9
Step 2 - Multiply both sides of the equation by four and move the terms to the left side
x^2/ 4 + 2x - 9 = -x^2/ 4 - 6x + 9
x^2/ 4 + 2x - 9 • 4/4 = -x^2/ 4 - 6x + 9 • 4/4
x^2 + 8x - 36 = -x^2 - 24x + 36
x^2 + 8x - 36 + x^2 + 24x - 36 = 0
Step 3 - Simplify & factor the common term
x^2 + 8x - 36 + x^2 + 24x - 36 = 0
2x^2 + 32x - 72 = 0
2(x^2 + 16x - 36) = 0
2(x - 2)(x + 18) = 0
x = 2, 18
Step 4 - Substitute x into the first equation and solve
y = x^2/4 + 2x - 9
y = 2^2/4 + 2 • 2 - 9, (-18)^2/4 + 2 • -18 - 9
y = -4, 36
Therefore, the points should be (2, -4) and (-18, 36).

An artist enlarged a drawing she made. The original is 3 cm wide and 5 cm tall. The artist set the copier zoom button to 120%. What is the longer dimension of the new drawing?
Pls help
Answers
Answer:
the answer is 6 cm
Step-by-step explanation:
Here’s one way you can solve this problem.
A zoom setting of one hundred twenty percent means that the dimensions of the new copy will be one hundred twenty percent of the dimensions of the original drawing.
First, write the scale that expresses the ratio of the original percent to the copy percent, one hundred to one hundred twenty.
Then, let h represent the height of the copy and write the ratio of copy to original as five centimeters to h centimeters.
Next, write a proportion that equates the two ratios. One hundred to one hundred twenty equals five to h.
Then, cross multiply the terms of the proportion. One hundred twenty times five equals one hundred h.
Next, multiply to get six hundred equals one hundred h.
Finally, divide both sides by one hundred to find h. h equals six.
So, the longer dimension of the new drawing is six centimeters, which is one hundred twenty percent of five centimeters.
