Lauren solved the equation - 3y - 18x = 12x - 21 for y and got y = 10x -
7 as the answer. Is this the correct answer?
O Yes
O No
Answer:
No, it's incorrect.
Step-by-step explanation:
The answer should be y = -10x + 7
3x^2 – 10x = 8
(it’s to the 2nd power btw)
Answer:
x = 4, (-2/3)
Step-by-step explanation:
3(x^2) – 10x = 8
3(x^2) – 10x - 8 = 0
(3x + 2)(x - 4) = 0
(3x + 2) = 0
3x = -2
x = (-2/3)
(x - 4) = 0
x = 4
Answer:
x = -2/3, 4
Step-by-step explanation:
move all terms to one side
3x^2 - 10x - 8 = 0
split the terms in 3x^2-10x-8 into two terms
3x^2+2x-12x-8=0
factor out common terms in first to and last to
x(3+2)-4(3x+2) =0
factor out common term 3x+2
(3x+2) (x-4)=0
solve for x
x=-2/3,4

Mr. Fitch needs to get a loan to replace the air-conditioning system in his home. The cost of the replacement, including installation, is $4,348.00. He can apply for a 5- year loan or a 3-year loan. Both loans involve simple interest with an annual interest rate of 6.5%. If Mr. Fitch applies for the 5-year loan, how much more will he pay in interest than with the 3-year loan? F. $704.98 G. $565.24 H. $2,260.96 J. $56,524.00
Answer: g
Step-by-step explanation:
4348x.065=282.62
282.62x5=1413.1
282.62x3=847.86
1413.1-847.86=565.24
Compared to a 3-year loan he has to pay G. $565.24 more for a 5-year loan.
What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, Mr. Fitch needs to get a loan to replace the air-conditioning system.
He can apply for a 5- year loan or a 3-year loan. Both loans involve simple interest with an annual interest rate of 6.5%.
Here, p = $4,348.00, r = 6.5%, t₃ = 3 and t₅ = 5.
For, t₃.
SI₃ = (4348×6.5×3)/100.
SI₃ = $847.86.
For, t₅.
SI₅ = (4348×6.5×5)/100.
SI₅ = $1,413.1.
So, the amount of interest he will have to pay more is (SI₅ - SI₃).
= $(1,413.1 - 847.86).
= $565.24.

The cost c in dollars to rent a surfboard is proportional to the number of hours H it cost you $30 to rent a surfboard for five hours this situation is c equals
Answer:
c = 6H
Step-by-step explanation:
This is a question showing that there is a direct variation between the cost, c, and hours, H.
So that;
c ∝ H
∝ is the proportionality sign
c = kH
where k is a constant of proportionality.
Thus, given that c = $30 and H = 5 hours, then;
30 = k x 5
30 = 5k
Divide both sides by 5 to have;
k = [tex]\frac{30}{5}[/tex]
k = 6
For this situation, since k = 6; then,
c = 6H

A bag contains 15 marbles. The probability of randomly selecting a green marble is One-third. The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is StartFraction 1 over 15 EndFraction. What is the probability of randomly selecting a red marble
Answer:
1/5
Step-by-step explanation:
Total Number of Marbles in the bag = 15
The probability of randomly selecting a green marble is 1/3
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble = 1/15
The probability of randomly selecting a green marble, replacing it, and then randomly selecting a red marble is calculated as
The probability of randomly selecting a green marble × The probability of randomly selecting a red marble
Hence:
1/15 = 1/3 × R
1/15 = R/3
Cross Multiply
R × 15 = 1 × 3
R= 3/15
R= 1/5
Hence, the probability of randomly selecting a red marble is 1/5

Step-by-step explanation:
Find $\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1}$
Answer:
1Step-by-step explanation:
Given the expression [tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1}[/tex]
According to indices:
[tex]a^{-1} = \frac{1}{a}[/tex]
Applying this to the question:
[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{1}\left\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right}[/tex]
Hence:
[tex]\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = \frac{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]}{\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]} \\\\\left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right] \cdot \left[\left(\frac{2}{5}\right)^{12} \left(\frac{3}{16}\right)^{-8}\right]^{-1} = 1[/tex]
