Answer:
y = (5/4)x - 4
Step-by-step explanation:
As we move from (0, -4) to (4, 1), x increases by 4 and y increases by 5.
Thus, the slope of the line segment connecting these two points is
m = rise / run = 5/4.
Subbing these knowns into the point-slope formula for the equation of a straight line, we get:
y - 1 = (5/4)(x - 4), or
y = (5/4)x - 5 + 1, or
y = (5/4)x - 4
Let's check this out. Determine whether or not (0, -4) satisfies the equation:
-4 = (5/4)(0) - 4
Yes, this is true; the equation is correct.
A person can read 48 pages in 5/4 of an hour. How many pages can they read in one hour
Answer:
38.4 pages
Step-by-step explanation:
5/4 = 1.25
Rate = pages / Time
Time = 1.25 hours
Pages = 48
Rate = 48/1.25
Rate = 38.4

Alicia´s gross monthly pay is 1,700. Alicia pays 1.25% of her monthly salary for Medicare. how much dose she pay
Answer:
$21.25
Step-by-step explanation:
1700 x 1.25% = 1700 x 0.0125 = 21.25
So Alicia's paying $21.25 of her monthly salary to Medicare.
Answer:
$21.25
Step-by-step explanation:
If Alicia´s gross monthly pay is 1,700 and she pays 1.25% of her monthly salary for Medicare, she would pay $21.25.
In order to find this, you must multiply the gross monthly pay by the percent.
1,700 x 1.25 = 21.25
Arthur is creating a garden in his backyard. He has less than 250 square yards of space to use. He plans to use 25 square yards to plant flowers. He plans to divide the remaining space into plots of equal size for vegetables. Each vegetable plot will be 30 square yards. How many plots of equal size can Arthur plan for vegetables? PLEASE HELPPPPPP!!
7 because subtract 25 from 250 the divide 225 by 30 to get 7.5 so he can only use 7 square yards

4p + 25 = 6(p – 3) – 3(4 – 3p)
Answer:
p = 5
Step-by-step explanation:
first you need to distibute into the parenthesis's -
4p + 25 = 6(p-3) -3(4-3p)

Step-by-step explanation:
A flashlight is projecting onto a wall, as shown below
Answer:
n = 30
Step-by-step explanation:
The triangles share the same angle measures, so they are similar triangles. The side lengths of similar triangles are proportional to each other, so we can set up a proportion and solve for n...
16 is to 20 as 24 is to n
16/20 = 24/n now solve for n by cross multiplying
16n = 480
n = 30 (divide both sides by 16)
We are given that the original triangle and its projection are similar. This means that the corresponding angles of the two triangles are congruent, and the ratios of their side lengths are equal.
We are also given the lengths of two sides of the original triangle: 16 cm for the base and 20 cm for the hypotenuse. We are asked to find the missing length on the projection, which corresponds to the base of the original triangle.
To solve this problem, we can set up a proportion based on the similar triangles. Let x be the missing length on the projection:
(base of original triangle) / (base of projection) = (hypotenuse of original triangle) / (hypotenuse of projection)
Substituting the known values:
16 cm / x = 20 cm / 24 cmCross-multiplying:
16 cm * 24 cm = x * 20 cm384 [tex]cm^2[/tex] = 20x [tex]cm^2[/tex]x = 384 [tex]cm^2[/tex] / 20 [tex]cm^2[/tex]x = 19.2 cmTherefore, the missing length on the projection is 19.2 cm. However, the answer choices are all rounded to one decimal place.
Rounding 19.2 cm to one decimal place gives us 19.0 cm. Therefore, none of the provided options are correct.

the graphs below have the same shape. What is the equation of the blue graph?
Option: C is the correct answer.
The equation of the blue graph i.e. function G(x) is:
C. [tex]G(x)=(x+3)^2+1[/tex]
Step-by-step explanation:We are given a parent function F(x) as:
[tex]F(x)=x^2[/tex]
Now after looking at the graph of the transformed function G(x) we see that the graph of G(x) is obtained by shifting the graph of F(x) 3 units to the left and 1 units upward.
Hence, the equation of the transformed function G(x) is given by:

If point A is located at (-9,2)on the coordinate plane and point B is located at (-9,10)what is the distance between the two points?
Answer:
8 units
Step-by-step explanation:
The x coordinates don't change so you just subtract 2 from 10 to get the distance.
Answer:
8
Step-by-step explanation:
To calculate the distance d, using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 9, 2) and (x₂, y₂ ) = B(- 9, 10)
d = [tex]\sqrt{(-9+9)^2+(10-2)^2}[/tex]

Otis had a salad for $4.50, a sandwich for $6.25, and a drink at his favorite restaurant. The tax for the entire meal was $0.54. What was the price of the drink?
Answer:
Price of the drink = $1.25
Step-by-step explanation:
4.5% * ( $4.5 + $6.25 + drink) = $0.54
4.5/100 * ( $4.5 + $6.25 + drink) = $0.54
0.045 * ( $4.5 + $6.25 + drink) = $0.54
0.045/0.045 * ( $4.5 + $6.25 + drink) = $0.54/0.045
( $4.5 + $6.25 + drink) = $12
10.75 + drink = $12
drink = $12 - $10.75
drink = $1.25
The price of the drink is $1.25
How to determine the price of the drink?The given parameters are:
Tax amount = $0.54
Salad = $4.50
Sandwich = $6.25
Let the price of the drink be x.
Given that the sales tax is 4.5%, we have:
4.5% * ( $4.5 + $6.25 + x) = $0.54
Divide both sides by 4.5%
( $4.5 + $6.25 + x) = $12
Evaluate the sum
$10.75 + x= $12
Subtract $10.75 from both sides
x = $1.25
Hence, the price of the drink is $1.25

Does the point (3,-1) lie on the circle (x+1)2 +(y-1)2=16?
Final answer:
After substituting the x and y values of the point (3,-1) into the circle's equation, it is determined that (3,-1) does not lie on the circle since the equation does not hold true.
Explanation:
To determine if the point (3,-1) lies on the circle given by the equation [tex](x+1)^2 + (y-1)^2[/tex]=16, we must substitute the x and y values of the point into the equation and see if the equation holds true.
Let's plug in x = 3 and y = -1:
[tex](3+1)^2 + (-1-1)^2[/tex]= 16
[tex](4)^2 + (-2)^2[/tex] = 16
16 + 4 = 20
Since 16 + 4 does not equal 16, the point (3, -1) does not lie on the circle
A box is 8 1/2 inches wide 12 3/4 inches long in 5 1/2 inches tall what is the total surface area of 3 such boxes
Step-by-step explanation:
Surface Area Formula: SA=2lw+2lh+2hw
SA is surface area. l is length, w is width, h is height. Make sure to follow PEMDAS and keep multiplication together before adding.
Now substitute values
2(12 3/4*8 1/2)+ 2(12 3/4 * 5 1/2)+ 2(5 1/2*8 1/2)
SA=450.5 inches squared
To find the total surface area of three identical boxes with given dimensions, calculate the surface area of one box using the formula for a rectangular prism and then multiply by three. The total surface area of three boxes is 1351.5 square inches.
Calculating the Total Surface Area of Three Boxes
The question involves finding the total surface area of three identical boxes, each with the dimensions 8 1/2 inches wide, 12 3/4 inches long, and 5 1/2 inches tall. To calculate the surface area of one box, we use the formula for surface area of a rectangular prism:
SA = 2lw + 2lh + 2wh
where SA is the surface area, l is the length, w is the width, and h is the height. Convert fractions to decimals for easy calculation:
Width (w) = 8.5 inches
Length (l) = 12.75 inches
Height (h) = 5.5 inches
Applying the dimensions:
SA = 2(12.75)(8.5) + 2(12.75)(5.5) + 2(8.5)(5.5)
Calculate and add up the areas for each pair of sides:
SA = 2(108.375) + 2(70.125) + 2(46.75)
SA = 216.75 + 140.25 + 93.5
Sum to find the total surface area for one box:
SA = 450.5 square inches
To find the total surface area for three boxes, multiply the surface area of one box by 3:
Total SA = 450.5 * 3
Total SA = 1351.5 square inches
The total surface area of three such boxes is 1351.5 square inches.
