Answer:
Step-by-step explanation:
In point-slope form, our equation would be y - 9 = 2(x - 1). Expanding, we get y - 9 = 2x - 2. Solving for y, we obtain the form of the equation as shown in the problem: y = 2x + 7.
So, the numbers that would go in the blanks would be 2 and 7, respectively.

what is 5 1/3 divided by 1 1/6
Answer:
32/7 or 4 4/7
Step-by-step explanation:
I used mathaway. JOKING!
Convert the fractions into mixed numbers.
So instead of 5 1/3 and 1 1/6
you will have 16/3 and 7/6
Apply the fraction rule
a/b ÷ c/d = a/b × c/d
= 16/1 x 2/7
then:
16 x 2
1 x 7
= 32/7
proper fraction: 4 4/7
Joyce paid $94.50 for an item at the store that was 55 percent off the original price. What was the original price?
Answer:
$210
Step-by-step explanation:
The original price of the item = 100%
If the item was reduced by 55%, then the discounted price of the item = 100% - 55% = 45%
Therefore, $94.50 = 45% of the original price.
45% = 45/100 as a ratio
Using ratios, and letting [tex]x[/tex] be the original price:
94.50/[tex]x[/tex] = 45/100
Cross multiply: 94.50 x 100 = 45 x [tex]x[/tex]
9450 = 45[tex]x[/tex]
Divide both sides by 45: 210 = [tex]x[/tex]
Therefore, the original price of the item was $210
Alternatively, divide 94.50 by 45 to get the cost per 1%. Then multiply this by 100 to get the original price (100%):
(94.50 ÷ 45) x 100 = 210

A 5 person sports team has an average 40 yard dash time of 5. 7 seconds. When a 6th player is added to the team, the new mean is 5. 5 seconds. What is the new players personal time for the 40 yard dash?.
The new player's personal time is 4.5 seconds.
What is the new player's personal time?
The first step is to determine the total time the 5 persons complete the dash.
Total time = 5 x 5.7 = 28.5 seconds
The second step is to determine the total time for the 6 people to complete the dash.
Total time = 6 x 5.5 = 33 seconds
The third step is to find the difference of the time in the previous two steps: 33 - 28.5 = 4.5 seconds

4.32A radio tower 200 ft. high casts a shadow 75 ft. long. What is the angle of elevation of the sun?
Angle of elevation of the sun: 69 degrees
Step-by-step explanation:
tan(x) = 200/75
x = tan^-1 (200/75)
x = 69 degrees
The angle of elevation of the sun is .
What is tangent of an angle?
The tangent of an angle is the ratio of height to base of the angle.
If we take the angle as Ф, then tan Ф = height/base.
Given, length of the tower is 200 ft. and the length of the shadow is 75 ft.
Let, the angle of elevation of the sun = Ф
Therefore, tan Ф = height/base = 75/200 = 0.375
Hence, Ф = [tex]tan{-1}[/tex](0.375) =
The angle of elevation of the sun is .

Kardal used the line of best fit to predict that a man 80 inches tall would wear about a size 16 shoe. What can be concluded about this prediction? Check all that apply.
The prediction is reasonable.
The prediction is an interpolation.
No data is given in the scatterplot for a height of 80 inches, but a shoe size can still be predicted.
