Answer:
- 22°F
Step-by-step explanation:
Given that :
Morning temperature = 15°F
Change in temperature = fall by 37 degree
The temperature of the end of the day:
Morning temperature + (change in temperature)
Fall by 37° = decrease in temperature by 37° = - 37°
15°F + (-37°F)
15°F - 37°F
= - 22°F
Compare your answer to the model. Yes, it is a direct variation. If the ordered pairs form a direct variation, the rate of change is constant and the ratio of y over x is constant. The rate of change, or constant of variation, is 0.5. What did your explanation include? a reference to the rate of change a reference to the ratio of y over x the constant of variation as 0.5

Write the equation of the line that passes through the points (5,0) and (-6, -1).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.
Answer:
The equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]
Step-by-step explanation:
We need to find equation of line in point slope form that passes through points (5,0) and (-6, -1).
The general equation of point slope form is: [tex]\mathbf{y-y_1=m(x-x_1)}[/tex]
where m is the slope of line.
We need to know Slope m
Finding Slope m
Finding Slope m using formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have [tex]x_1=5, y_1=0, x_2=-6 \ and \ y_2=-1[/tex]
Putting values and finding slope
[tex]Slope=\frac{-1-0}{-6-(5)}\\Slope=\frac{-1}{-6-5}\\Slope=\frac{-1}{-11}\\Slope=\frac{1}{11}[/tex]
So , slope m is: [tex]\mathbf{m=\frac{1}{11}}[/tex]
Using point (5,0) and slope m =1/22 the equation of point-slope form is:
[tex]y-y_1=m(x-x_1)\\y-0=\frac{1}{11} (x-5)\\y=\frac{1}{11}x-\frac{5}{11}[/tex]
So, the equation in point-slope form is: [tex]\mathbf{y=\frac{1}{11}x-\frac{5}{11} }[/tex]

Does the information on the sign represent a proportional relationship?
Explain how you know.
6
Answer: Yes. There's a proportional relationship
Step-by-step explanation:
We are told that Anthony and Miguel go to the store to purchase some new DVDs and that an advertisement in the window catches their attention as they saw that:
3 DVDs cost $22,50. This means the price of one will be:
= $22.50 / 3
= $7.50
5 DVDs cost $37.50. This means that the price for one will be:
= $37.50 / 5
= $7.50
Since the price of a DVD both cost $7.50, it means that the information on the sign represent a proportional relationship.

Determine if the ordered pair (1,-3) is a solution to the system of equations below:
y = x - 4
y = 9x - 12
Answer:
Yes, it is a solution
Step-by-step explanation:
(x,y) (1,-3)
a. Plug in x:
y= 1-4
y = -3 yes this is correct as -3 is on y.
b. Plug in X.
y=9(1)-12
y=9-12
y=-3 yes this is also correct as this also is -3 for y.
Consider the conditional statement of N is the midpoint of CD then CD =2CN what is the hypothesis
Answer:
Step-by-step explanation:
If N is the midpoint of CD, it means that N bisects the line CD. Hence;
CN + ND = CD .... 1 and;
CN = ND .... 2
Substitute equation 2 into 1;
CN + CN = CD
2CN = CD
Rearrange;
CD = 2CN (proved)
The hypothesis is the midpoint hypothesis and the hypothesis is TRUE

110 meters of fencing are used to fence a rectangular pasture of 750 square meters of farmland. If the length of the pasture is longer than the width, what is the width of the pasture in meters?
Answer:
25mStep-by-step explanation:
Perimeter of the rectangular pasture P = 2(L+W)
Area A = LW
L is the length
W is the width
Given
Perimeter = 110m
Area = 750m
If the length of the pasture is 40m longer than the width, then L = W+40
110 = 2L+2w
55 = L+W .....1
750 = LW.....2
Solving simultaneously
from 1; L = 55-W
substitute into 2;
750 = (55-W)W
750 = 55W-W²
-W²+55W -750 = 0
W²-55W+750 = 0
(W²-25W)-(30W+750) = 0
W(W-25)-30(W-25) = 0
(W-25)(W-30) = 0
W-25 = 0 and W-30 = 0
w = 25m and 30m
Since L = 55-W
L = 55-25 = 30m and;
L = 55-30 = 25m
Since we are told that length id longer than the width then, the width we are going to use is 25m

A local shoe store buys shoes at a wholesale price and then marks them up 80% to calculate the retail price. The wholesale price varies, depending on the quantity of shoes purchased. (2 points)
Quantity
0-20 pairs
21-40 pairs
41-60 pairs
61-80 pairs
81 or more pairs
Wholesale Price
(per pair)
$25.00 each
$23.00 each
$21.00 each
$19.00 each
$17.00 each
What is the quantity of pairs and how much are they each pair??
Answer:
They buy at wholesale and sell at an 80% markup. The retail prices are;
0 - 20 pairs.
= 25 * 1.80
= $45.00
21 - 40 pairs
= 23 * 1.80
= $41.40
41 - 60 pairs
= 21 * 1.80
= $37.80
61 - 80 pairs
= 19 * 1.80
= $34.20
81 or more pairs
= 17 * 1.80
= $30.60

I hope this helps you to understands better
The next two-term of the sequence is 1536 and 6144 and the multiplicity is 4
Given the sequence of numbers expressed as 6, 24, 96, 384, ...
The given sequence is a geometric sequence. The nth term of the sequence is expressed as;
[tex]T_n = ar^{n-1}[/tex]
a is the first term
r is the common ratio or multiplicity
n is the number of terms
Given the following parameters
a = 6
r = 24/6 = 96/24 = 4
n = 5 and 6 (5th and 6th term)
For the fifth term;
[tex]T_{5} = 6(4)^{5-1}\\T_5=6(4)^4\\T_5 = 1536[/tex]
For the sixth term;
[tex]T_{6} = 6(4)^{6-1}\\T_6=6(4)^5\\T_6 = 6144[/tex]
Hence the next two-term of the sequence is 1536 and 6144 and the multiplicity is 4

The product of (2 + 7i) (2 - 7i) in the form of a + bi is 53 + 0i.
What is an imaginary number?An imaginary number is denoted by i.
The value of i is √-1.
i² = √-1² = -1
We have,
(2 + 7i) (2 - 7i)
We need to write in the form of a + bi.
a + bi
a = real number
b = imaginary part
(2 + 7i) (2 - 7i)
Remove the brackets.
= 2 x (2 - 7i) + 7i x (2 - 7i)
= 4 - 14i + 14i - 49i²
= 4 - 14i + 14i - 49 x -1
= 4 - 14i + 14i + 49
= 4 + 49
= 53
We have only the real part.
So,
The product of (2 + 7i) (2 - 7i) is 53 + 0i.
Thus,
The product of (2 + 7i) (2 - 7i) in the form of a + bi is 53 + 0i.

Which of these is a factor of 10?
A. 20
B. 2
C. 4
Answer:
B. 2
Hope this helps!
Step-by-step explanation:
The factors of 10 are 1, 2, 5, and 10. You can also look at this the other way around: if you can multiply two whole numbers to create a third number, those two numbers are factors of the third. 2 x 5 = 10, so 2 and 5 are factors of 10. 1 x 10 = 10, so 1 and 10 are also factors of 10.

A police car is approaching a right-angled intersection from the north at 35 mph, and a speeding car is heading east at 30 mph. When the police car is 0.75 miles north of the intersection and the speeding car is 1 mile to the east, what is the rate that the distance between the police car and car is changing?
Answer:
The rate that the distance between the police car and car is changing = 3 m/s
Step-by-step explanation:
The given speed of the police car = 35 mph
The speed of the speeding car = 30 mph
The position of the police car = 0.75 miles north
The position of the speeding car = 1 miles east
The distance of the police car from the speeding car, d = √(0.75² + 1²) = 1.25
d² = x² + y²
2d·dd/dt = 2x·dx/dt + 2·y·dy/dt
Where;
dx/dt = 30 mph
dy/dt = -35 mph
x = 1
y = 0.75
Substituting gives;
2×1.25 ×dd/dt = 2×1×30 - 2×0.75×35
2×1.25 ×dd/dt = 7.5
dd/dt = 7.5/2.5 = 3
dd/dt = 3 m/s
The rate that the distance between the police car and car is changing = dd/dt = 3 m/s
Answer:
The answer is increasing by 3 mph
