Answer:
a) $2.40
b) $16.80
c) y = -2.40x +16.80
Step-by-step explanation:
a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4
Dylan spends $2.40 at lunch every day.
__
b. The y-intercept can be found from the formula ...
b = y1 -m(x1)
b = 12 -(-2.40)(2) = 16.80
Dylan's dad gives him $16.80 at the beginning of each week.
__
c. The slope-intercept equation is ...
y = mx + b
y = -2.40x +16.80

At a farm four employees harvest 48 pounds of food over a certain number of hours each employee works the number of hours shown
Answers
Complete question :
At a farm, four employees harvest 48 pounds of food over a certain numbers of hours. Each employee works the numbered of hours shown. Employee A: 6 hours employee B: 4 hours employee C: 6 hours employee D: 8 hours The number of pounds of food harvested by each employee is proportional to the number of hours worked. Fill in the table with the amount of food, in pounds, each employee harvested.
Answer:
A = 12 lbs ;
B = 8 lbs
C = 12 lbs
D = 16 lbs
Step-by-step explanation:
Total hours worked :
(A + B + C + D)
(6 + 4 + 6 + 8) hours = 24 hours
Total pounds of food = 48 pounds
Pounds harvested per hour = 48 pounds / 24 hours = 2 pounds per hour
Amount of food harvested by each employee :
A = 6 * 2 = 12 pounds
B = 4 * 2 = 8 pounds
C = 6 * 2 = 12 pounds
D = 8 * 2 = 16 pounds

A string reaches from the top of a 17-foot pole to a point 13 feet from the base of the pole. To the nearest tenth of a foot, how long is the string?
Answers
Answer:
21.4 feets
Step-by-step explanation:
Using Pythagoras rule :
The length of the string:
Hypotenus = sqrt(opposite² + adjacent²)
Length of string = sqrt(17² + 13²)
Length = sqrt(289 + 169)
Length of string = sqrt(458)
Length of string = 21.400
Length = 21.4 feets

use the exponent rule to simplify
Answers
Answer:
[tex]y^{-5}[/tex]
Step-by-step explanation:
The Exponent Quotient Rule states that if two terms of the same base are being divided by each other, then the simplified expression is the base to the first power subtracted by the second power. As an algebraic equation, that would be [tex]\frac{x^{a} }{x^{b} } =x^{a-b[/tex], where [tex]x[/tex] is the common base and [tex]a[/tex] and [tex]b[/tex] are the exponents.
In this case, [tex]x=y[/tex], [tex]a=2[/tex], and [tex]b=7[/tex], so we know that [tex]\frac{y^{2} }{y^{7} } =y^{2-7}=y^{-5}[/tex]. Hope this helps!
The average test score for 8 students is 5 the scores for 7 of the 8 students are shown what is the score of the 8th student
Answers
Answer:
70
Step-by-step explanation
Find the diagram attached
Average = Sum of scores/sample size
Given the 7 numbers
20, 20, 20, 30, 80, 80, 80
Average = 50
5 = 20+20+20+30+80+80+80+x/8
x is the score of the 8th student
50 = 330+x/8
400 = 330+x
x = 400-330
x = 70
Hence the score of the 8th student is 70

There were 36 sweatshirts on sale for 2/3 of the regular price. What was
the sale price if the regular price was $30?
Answers
Answer:
To sum up, we solved for W. Finally, the sale price of a sweatshirt was 20$.
Step-by-step explanation:
So we have our main equation of W/G=p. The G stands for the total amount which is 30. The W is the unknown in this case. As for the p equals 2/3.
Thus we substitute G and p into the equation W/30=2/3. We multiply both sides of the equation with 30 W=2*30/3. Which gives us 60/3=20.

Match each function on the left to all points on the right that would be located on the graph of the function
Answers
By direct evaluation we have found the following results about functions and points:
The points (1, - 3) and (5, 5) are part of the function f(x) = 2 · x - 5.The point (1, 1) is part of the function f(x) = 2 · x² - 8 · x + 7.The point (4, 1) is part of the function f(x) = 2√(x - 4) + 1.What function does a point belong to?Herein we have three functions and four points which has to be checked with respect to each of these functions. A quick approach consists in evaluating each function at every value of x and choose from the outputs.
Case A
f(1) = 2 · 1 - 5
f(1) = - 3
f(4) = 2 · 4 - 5
f(4) = 3
f(5) = 2 · 5 - 5
f(5) = 5
The points (1, - 3) and (5, 5) are part of the function f(x) = 2 · x - 5.
Case B
f(1) = 2 · 1² - 8 · 1 + 7
f(1) = 1
f(4) = 2 · 4² - 8 · 4 + 7
f(4) = 7
f(5) = 2 · 5² - 8 · 5 + 7
f(5) = 17
The point (1, 1) is part of the function f(x) = 2 · x² - 8 · x + 7.
Case C
f(1) = 2√(1 - 4) + 1
f(1) = NaN
f(4) = 2√(4 - 4) + 1
f(4) = 1
f(5) = 2√(5 - 4) + 1
f(5) = 3
The point (4, 1) is part of the function f(x) = 2√(x - 4) + 1.

The floor of Catelyn's bedroom has an area of 123 1/2 square feet. The walls are 9 1/2 feet tall. What is the volume of Catelyn's bedroom?
Answers
Answer:
Volume of the Catelyn's bedroom = [tex]1173\frac{1}{4}[/tex] cubic feet
Step-by-step explanation:
Floor of Catelyn's bedroom has area = [tex]123\frac{1}{2}[/tex] square feet
= 123.5 square feet
Height of the walls = [tex]9\frac{1}{2}[/tex] feet
= 9.5 feet
Shape of the room is like a rectangular prism.
Therefore, volume of the bedroom = Area of the rectangular base × Height
= 123.5 × 9.5
= 1173.25
= [tex]1173\frac{1}{4}[/tex] cubic feet
