1. Proportional
Y is 5 times x
2. Not Proportional
Y is .5 times x
Answer:
x and y are not proportional in either table.
Step-by-step explanation:
x and y are not proportional in the first table. Notice that y = x/5 for x = 30, 25, 45 but not for x = 14. The relationship between x and y must be consistent.
x and y are not proportional in the second table. y = 2(4) = 8
and y = 3(5) = 15. In order for x and y to be proportional y = kx where k is constant. This is not happening in the second table.

Determine how much you would receive in return for a 8 month, $500 loan to a friend if you charged the 3% annual interest.
Answers
Answer:
You would receive $510.08 in return.
Step-by-step explanation:
In order to find the answer, you can use the formula to calculate the future value:
FV=PV*(1+i)^n
FV=future value
PV= present value= 500
i= interest rate=0.03/12=0.0025 per month
n= number of periods of time= 8
Now, you can replace the values in the formula:
FV=500*(1+0.0025)^8
FV=500*(1.0025)^8
FV=510.08
According to this, the answer is that you would receive $510.08 in return.

1. A carpenter makes bookcases in 2 sizes, large and small. It takes 4 hours 2 points
to make a large bookcase and 2 hours to make a small one. The carpenter
can spend only 32 hours per week making bookcases and must make at
least 2 of the large and at least 4 of the small each week. Create a system
of linear inequalities to model this situation. *
Answers
The system of linear inequalities to model this situation is 4x+2y≤32, x≥2, y≥4. The correct option is (a).
The inequality 4x + 2y ≤ 32 represents the total number of hours available per week, which is limited to 32 hours.
The inequality x ≥ 2 represents that the carpenter must make at least 2 large bookcases per week.
The inequality y ≥ 4 represents that the carpenter must make at least 4 small bookcases per week.
These inequalities ensure that the carpenter stays within the time constraint of 32 hours and fulfills the minimum quantity requirements for both large and small bookcases.
Thus, the correct option is (a).

Step-by-step explanation:
Antonia currently has $4,500 in her
savings account. She saves $150 per
month. Cal currently has $3,400 in his
account. He saves $250 per month. How
much more money than Antonia will Cal
have after 12 months?
Answers
Answer:
The amount of more money than Antonia that Cal will have in his account after 12 months is $100
Step-by-step explanation:
The given parameters are;
The amount Antonia currently has in her savings account, P₁ = $4,500
The amount Antonia saves per month, S₁ = $150
The amount Cal currently has in his savings account, P₂ = $3,400
The amount Cal saves per month, S₂ = $250
Let the
The amount, 'A₁', Antonia has in 12 months is given as follows;
A₁ = P₁ + 12 × S₁
∴ A₁ = $4,500 + 12 × $150 = $6,300
Similarly, the amount, 'A₂', Cal has in 12 months is found as follows;
A₂ = P₂ + 12 × S₂
∴ A₂ = $3,400 + 12 × $250 = $6,400
The amount of money than Antonia that Cal will have after 12 months, 'A₂₋₁', is given as follows;
A₂₋₁ = A₂ - A₁ = $6,400 - $6,300 = $100.
The amount of money than Antonia that Cal will have after 12 months, A₂₋₁ = $100.

Answers
Answer:
Step-by-step explanation:
Total cost b = 23.95 + 7.65c
b = 22.95 + 7.65c is the equation can be used to determine the cost of a bracelet, b, with c charms
What is slope intercept form of line?The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
Given that Jocelyn wants to purchase a bracelet with charms
Let the bracelete be b and the charms is denoted by c.
Each charm costs $7.65.
The bracelet costs $22.95.
We need to find the equation can be used to determine the cost of a bracelet, b, with c charms
b = 22.95 + 7.65c
Hence, b = 22.95 + 7.65c is the equation can be used to determine the cost of a bracelet, b, with c charms

3 A garage is to be built with a skillion roof (a roof with a single
slope). The measurements are given in the diagram. Calculate
the pitch line length, to the nearest millimetre. Allow 500 mm
for each of the eaves.
Answers
Answer:
1e1e
Step-by-step explanation:
The pitch line length of the garage with the skillion roof, with the given dimensions and eave overhangs, is approximately 7.5 meters.
To calculate the pitch line length for the garage with a skillion roof, we need to consider the dimensions provided in the diagram and add the eave overhangs.
Let's assume the length of the garage is L meters, and the height from the top of the walls to the peak of the roof is H meters.
Calculate the pitch line length of the roof:
The pitch line length is the diagonal length of the triangular roof face. We can use the Pythagorean theorem to find it.
Pitch Line Length (PL) = √(L² + H²)
Add the eave overhangs:
The eave overhang is 500 mm on each side, so we need to add 1 meter (1000 mm) to the pitch line length.
Total Pitch Line Length (TPL) = PL + 1000
Now, let's calculate the pitch line length to the nearest millimeter.
For example, let's assume L = 6 meters and H = 2.5 meters.
Calculate the pitch line length (PL):
PL = √(6² + 2.5²)
PL = √(36 + 6.25)
PL = √42.25
PL = 6.5 meters
Add the eave overhangs:
TPL = 6.5 + 1
TPL = 7.5 meters

We have an alrebaric expressio and are asked to solve for x, which to do this, we need to isolate x.
2(4x + 5) = 9(3x + 2)
Distribute :
(2(4x) + 2(5)) = (9(3x) + 9(2))
8x + 10 = 27x + 18
Subtract 10 from both sides :
8x = 27x + 8
Subtract 27x from both sides :
-19x = 8
8 = -19x
