Answer:
y = 3x + 1
Step-by-step explanation:
y = 3x + b
-5 = 3(-2) + b
-5 = -6 + b
1 = b

2) Mr. Jenkins deposited $1,200 into an account. He made no additional
deposits or withdrawals. Jenkins earned 4.0% annual simple interest on
the money in the account. What was the balance in dollars and cents in
Mr. Jenkins's account at the end of 4 years?
Hello, I Am BrotherEye
Answer:
The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Initial deposit = $ 1,250
Interest rate = 4.25% annual simple = 0.0425
Time of investment = 4 years
2. What was the balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years?
Let's recall the simple interest formula, as follows:
A = P * (1 + rt), where:
A = final amount
P = initial principal balance
r = annual interest rate
t = time (in years)
Replacing with the values we know:
A = P * (1 + rt)
A = 1,250 * (1 + 4 * 0.0425)
A = 1,250 * 1.17
A = 1,462.50
The balance in dollars and cents in Mr. Jenkins’s account at the end of 4 years was $ 1,462.50

Step-by-step explanation:
Aaron kept $12 000 in a bank account with an annual interest rate of 4%. After exactly 2 years, the bank chose Aaron as the winner for a prize money worth $5000. Aaron decided to invest all his savings and the prize money into a Trust Fund which offers a dividend of 4.5% per annum. When ( which year ) will all his investment value exceed $20 000?
Answer:
Initial amount P = $12000
Interest after 2 years I = 4%*2 = 8%
Investment into Trust fund:
$12000 + $5000 + 0.08*$12000 = $17960Interest amount to exceed $20000:
$20000 - $17960 = $2040Time required to get $2040:
17960*0.045x = 2040808.2x = 2040x = 2040/808.2x = 2.52 yearsThe investment will exceed $20000 in the second half of the third year

A circular flower bed is 17m in diameter and has a circular sidewalk around it that is 2m wide. Find the area of the sidewalk in square meters. Use 3.14 for (pie sign).
The area of the sidewalk is (insert answer) m(squared)
(Round to the nearest whole number as needed.)
Answer:53.38 is the answer
Step-by-step explanation:
The radius is always half of the diameter so half of 17 is 8.5. 8.5x3.14 is 26.69. Then you add 26.69+26.69 to get the answer. (I’m not positive that this is correct)

Line p is parallel to line q. If the measure of angle 3 is 54 what is the measure of angle 6?... Help
Answer:
54°
Step-by-step explanation:
Because p and q are parallel, angle 3 equal to angle 6 as they are alternative angles.
So angle 6 is 54°.
Alternative
Line p and line q is parallel, so that the sum of a pair of interior angles (angle 3 and angle 5, angle 4 and angle 6) are equal to 180°.
So angle 4 + angle 6 = 180°.
Find angle 4 first:
180° - angle 3 = angle 4
180° - 54° = 126°
So the measure of angle 6 is
180° - 126° = 54°
Answer:
54 degrees

Solve for x.
11.03 = 8.78 + 0.02x
Answer:
112.5
Step-by-step explanation:
11.03-8.78=0.02x
2.25=0.02x
x=2.25/0.02
x=112.5
What is the degree of 12x^4 -8x+ 4x^2 - 3?
Answer:
4
Step-by-step explanation:
In this problem, we are asked to determine the degree of the given expression 12X4 - 8X + 4X2 -3. To answer this, first, we need to arrange the mathematical expression in descending order with respect to its power such as the new arrangement will become 12x4 + 4x2 -8x -3. The degree is clearly visible and it is 4. Therefore, the answer to this problem is is 4.
Alyssa is a waitress at a restaurant. Each day she works, Alyssa will make a
guaranteed wage of $20, however the additional amount that Alyssa earns from tips
depends on the number of tables she waits on that day. From past experience, Alyssa
noticed that she will get about $15 in tips for each table she waits on. How much
would Alyssa expect to earn in a day on which she waits on 10 tables? How much
would Alyssa expect to make in a day when waiting on t tables?
Earnings for 10 tables:
Earnings for t tables:
Answer:
$170
20+15t
Step-by-step explanation:
she already makes $20 in a day and then you add the 10 times $15 in tips which makes 170.
for the equation, she makes 20 so you add it to 15 times t which is the hypothetical number of tables

i do not know for sure though.
there are two machines that can produce aluminum cans. The newer machine can produce 5400 cans in 180 minutes. It takes the older machine 217 minutes produce that many cans. If the two machines work together, how long will it take them to produce 5400 cans?
The newer machine works at a unit rate of
(5400 cans) / (180 min) = 30 cans/min
while the older machine operates at
(5400 cans) / (217 min) ≈ 24.88 cans/min
So working together, the two machines work at a rate of about 54.88 cans/min. Producing 5400 cans would then take about
(5400 cans) / (54.88 cans/min) ≈ 98.39 min
