Answer:
20
Step-by-step explanation:
8x=6x+5 (subtract 6x from both sides)
2x =5 (divide by 2 both sides)
x=2.5
8x= 8*2.5 = 20 (substitute 2.5 for x)
or 6x+5 = 6(2.5)+5 = 20 (substitute 2.5 for x)

Jericho wants to start saving to
purchase a house. His goal is to save $92,400. If he deposits $56,000 into an account that pays 2.92% interest compounded daily, approximately how long will it take for his money to grow to the desired amount? Round your answer to the nearest tenth of a year.
a) 19.3 years
b) 21.7 years
c) 15.4 years
d) 17.2 years
Answer:
its B
Step-by-step explanation:
If he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.
What is simple interest?It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.
It is given that,
Principal(P) = $56,000
Rate(R) = 2.92%
Time(T) = x years
Interest(I)=?
The amount to be collected to save the money is,
=$92,400 - $56,000
=$36,400
Interest = $36,400
The formula for the simple interest is,
I=(P×R×T)/100
Substitute the given value as
[tex]\rm 36400=\frac{\left(56000\times \:2.92T\right)}{100} \\\\ \frac{\left(56000\times \:2.92T\right)}{100}=36400 \\\\ \frac{100\times \:56000\times \:2.92T}{100}=36400\times \:100 \\\\ 163520T=3640000 \\\\ T=\frac{1625}{73} \\\\ T=21.7 \ years[/tex]
Thus, if he deposits $56,000 into an account that pays 2.92% interest compounded daily, it takes for his money to grow to the desired amount will be 21.7 years. Option b is correct.

Step-by-step explanation:
i know the coordinates are ( 0,-3 1/2 ) or ( 0, -3.5 ) for D
Answer:
(0,-2)
Step-by-step explanation:
Parallelograms have parallel lines and equal opposite lines.
You can count.
For Ex: A is 1 above and 5 to the left of B.
So D should be 1 above and 5 to the left of C.
C is at (5,-3)
Go up 1 and left 5 and you get (0,-2)

Answer:
No
Step-by-step explanation:
3x-8+3x+7-(simplified)-> 6x-1, which does not have (x+5) as a factor
Answer:
NoStep-by-step explanation:
Let's assume (x + 5) is the factor of f(x) = x^3 − 4x^2 + 3x + 7
then f(-5) should be equal to zero. Verifying:
f(-5) = (-5)^3 - 4(-5)^2 +3(-5) + 7 =-125 - 100 - 15 + 7 = -233Since -233 ≠ 0, the statement is false, so (x + 5) is not a factor of given polynomial

Step-by-step explanation:
The price of a skateboard was reduced from $150 to $90. By what percentage was the price of the skateboard reduced?
Answer:
40%
Step-by-step explanation:
Ignore the zeros, then think about the 15 ‘s multiplication table. Once you do, you will find that 90 is 15 times 6, which is 60%. And 100-60 is obviously 40. Hope this helps.
The percentage that was reduced from the original price is 40 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
The original price of the skateboard = $ 150
The reduced price of the skateboard = $ 90
The difference between the original price and reduced price =
Original price of the skateboard - Reduced price of the skateboard
The difference between the original price and reduced price = 150 - 90
= $ 60
Let the percentage decrease be A
Now the equation will be
Original price of the skateboard - A % ( Original price of the skateboard ) =
Reduced price of the skateboard
So ,
150 - A/100 ( 150 ) = 90
Adding A/100 ( 150 ) on both sides , we get
A/100 ( 150 ) + 90 = 150
Subtracting 90 on both sides , we get
A/100 ( 150 ) = 60
Multiply by 100 on both sides , we get
150A = 6000
Divide by 150 on both sides , we get
A = 40 %
Hence , the percentage at which the price of the skateboard reduced is 40%

How many solutions does the system of equations below have?
y = 3x + 4
y + 6 = 3x
Answer:
0 / no solutions
Step-by-step explanation:
Rewrite both in terms to the form y = equation.
EQ1: y = 3x + 4 (already in correct form)
EQ2: y = 3x - 6 (subtracting 6 from both sides).
Now suppose there is an intersection, then:
3x + 4 = 3x - 6, subtracting 3x from both sides gives:
4 = -6, which is a contradiction!
Therefore there are 0 / no solutions
