Explain how you would graph the line containing a slope of-1/5 that goes through the point (1,-4)
Answer:
y= -1/5x + 1/5
Step-by-step explanation:
y- y1 = m(x - x1)
Slope m=-1/5
(1, -4)
1 = y1
-4 = x1
y- 1 = -1/5(x-(-4))
y-1 = -1/5(x+4)
y-1= -1/5(x)+ -1/5(4)
y-1 = -1/5x + -4/5
add one to both sides
y= -1/5x + -4/5 + 1
y = -1/5x + 1/5

Answer:
Step-by-step explanation:
(2, -5) ; (-6 , -11)
Distance = [tex]\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]

The cost of renting a car is $ 30 /week plus $ 0.25 /mi travelled during that week. An equation to represent the cost would be y = 30 + 0.25 x , where x is the number of miles. What is your cost if you travel 35 miles? $ If you were charged $ 42.50 , how many miles did you travel? miles Get Help: VIDEO LicensePoints possible: 1
Answer:
Amount charged for 35 miles is $ 38.75
If amount charged is $ 42.50 then distance travelled is 50 miles
Step-by-step explanation:
Equation that represents the cost is [tex]y=30+0.25x[/tex]
Here,
x denotes the number of miles
$ 30 is the amount of rent per week
$ 0.25 is amount charged for 1 mi
To find cost if distance travelled is 35 miles, put [tex]x=35[/tex] in [tex]y=30+0.25x[/tex]
Cost (y) = [tex]30+0.25(35)=\$38.75[/tex]
So,
Amount charged for 35 miles is $ 38.75
To find number of miles for which amount charged is $ 42.50, put [tex]y=42.50[/tex] in [tex]y=30+0.25x[/tex]
[tex]42.50=30+0.25x\\42.50-30=0.25x\\12.5=0.25x\\x=\frac{12.5}{0.25} \\x=50[/tex]
So,
if amount charged is $ 42.50 then distance travelled is 50 miles.

If xy=13 and both x and y are positive integers, then what is the sum of x + y? Please show work
Answer:
14
Step-by-step explanation:
13 is a prime number
so it can only have the positive integer factors {1,13}
So {x,y} = {1,13} or {13,1}
In either case, 1+13 = 14
The sum of x + y is 14 .
What is prime number?A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29.
According to the question
xy=13
both x and y are positive
As 13 is a prime number
i.e
(x,y) can be only 1 or 13 .
To get 13 as product of xy
(x,y) must be equal to (1,13) or (13,1)
Therefore,
the sum of x + y = 13 + 1
= 14
Hence, the sum of x + y is 14 .

Challenge A company's stock began the day at $25.75 per share. That price drops by $1.08 each hour. What is the price per share after 4 hours? What would it be after 20 hours if this rate continues? Use pencil and paper. Explain what the signs of the answers mean in this context.
The price per share after hours is
nothing dollars.
Answer:
The price per share after 4 hours is $21.43
The price per share after 20 hours is $4.15
Step-by-step explanation:
Equations
The price of the company's stock is initially at $25.75 per share. Each hour the price drops by $1.08. This condition can be modeled by the function:
[tex]P(t)=25.75-1.08t[/tex]
Where t is the time in hours.
The sign means the function is decreasing as time passes.
When t=4 hours, the price will be:
[tex]P(4)=25.75-1.08\cdot 4=21.43[/tex]
The price per share after 4 hours is $21.43
Now find the price when t=20 hours
[tex]P(20)=25.75-1.08\cdot 20=4.15[/tex]
The price per share after 20 hours is $4.15

Rosa is putting carpet in her rectangular bedroom. She made a scale drawing using the scale 1 in = 3 ft. In the drawing the length is 5.5 in and the width is 3.25 inches. If the carpet is $2.58 per square foot, how much will it cost to carpet the bedroom?
Answer:
Total cost of carpet = $415 (Approx)
Step-by-step explanation:
Given:
Scale = 1 in = 3 ft
Length = 5.5 in
Width = 3.25 in
Carpet cost = $2.58 square foot
Find:
Total cost of carpet
Computation:
Actual Length = 5.5 x 3 = 16.5 ft
Actual Width = 3.25 x 3 =9.75 ft
Area = 16.5 x 9.75 = 160.875
Total cost of carpet = 2.58 x 160.875
Total cost of carpet = $415.0575
Total cost of carpet = $415 (Approx)

Statistics Canada reports that 13.7% of adult Canadians aged 15 or older report being limited in their daily activities due to a disability. If you take an SRS of 5000 Canadians aged 15 and over, what is the approximate distribution of the number in your sample who report being limited in their daily activities due to a disability? Select an answer choice. uniform distribution Normal distribution binomial distribution There is no distribution that approximates this situation well.
Answer:
A: Normal Distribution
Step-by-step explanation:
We are told that Statistics Canada reported 13.7% of adult Canadians aged 15 or older gave a report of being limited in their daily activities due to a disability.
Now, we are told that Simple Random Sample (SRS) of 5000 Canadians aged 15 and over was taken.
Now, the sample is 5000 and is therefore more than size of 30 which is the minimum for which we assume normal distribution from central limit theorem. This means that the approximate distribution of the number in the sample can be said to be a normal distribution.

Lyndsey’s advertising firm is working on a project for one of its customers. Lyndsey is asked to move a figure in the advertisement. The new figure must be similar to the old figure. The change is shown in the graph. Write a series of transformations that Lyndsey can use to move the old figure to the new figure. Explain why the figures are similar. *
Answer:
Step-by-step explanation:
Since, old figure is the dilated form of the new figure.
For the dilation of the old figure to new by a scale factor 's',
s = [tex]\frac{\text{Side length of the new figure}}{\text{Side length of the old figure}}[/tex] = [tex]\frac{2}{4}=\frac{1}{2}[/tex]
Rule for the dilation of a point by a scale factor 'k',
(x, y) → k(x, y)
→ (kx, ky)
If the vertices of the old triangle are dilated by a scale factor of [tex]\frac{1}{2}[/tex],
Coordinates of the dilated triangle of the old triangle will be,
A(3, 4) → A'([tex]\frac{3}{2}[/tex], 2)
B(3, 8) → B'([tex]\frac{3}{2}[/tex], 4)
C(5, 4) → C'([tex]\frac{5}{2}[/tex], 2)
Now these points are rotated by an angle of 90° counterclockwise about the origin,
Rule for the rotation is,
(x, y) → (-y, x)
[tex]A'(\frac{3}{2},2)[/tex] → A"(-2, [tex]\frac{3}{2}[/tex])
B'([tex]\frac{3}{2}[/tex], 4) → B"(-4,
C'([tex]\frac{5}{2}[/tex], 2) → C"(-2,
Further these points have been reflected across x-axis,
A"(-2, [tex]\frac{3}{2}[/tex]) → P(-2, -[tex]\frac{3}{2}[/tex])
B"(-4, [tex]\frac{3}{2}[/tex]) → Q(-4, -[tex]\frac{3}{2}[/tex])
C"(-2, [tex]\frac{5}{2}[/tex]) → R(-2, -[tex]\frac{5}{2}[/tex])
Therefore, old triangle is dilated by a scale factor of [tex]\frac{1}{2}[/tex], followed by rotation of 90° counterclockwise about the origin and then reflected across x-axis to form the new triangle.
please help me with this question. Given the functions f(x) = −2x + 30 and g(x) = 2x − 10, find the value of x for which f(x) = g(x).
Answer:
x = 10
Step-by-step explanation:
It says they equal each other so equal the two separate expressions together
-2x + 30 = 2x - 10
goal is to isolate variable x
add 2x to both sides (this cancels out the -2x on the left side)
30 = 4x - 10
add 10 to both sides (this cancels out the -10 on the right side)
40 = 4x
divide 4 by both sides (cancels out 4 on the right side)
10 = x
