Answer:
Step-by-step explanation:
Linear Equations do not have the value of x squared. They also shouldn't have the x value taken by the square root.
The second and third equations would be graphed as non-linear functions.
Answer:
Step-by-step explanation:
A $10,000 deposit at the bank will double in value in 9 years.
If the interest is r% and it is compounded each year, then we can write from the formula of compound interest that
⇒ 
⇒ 
⇒ r = 8%
Therefore, the formula for the accumulated amount t years after the investment is made will be
where, P is the invested principal and S is the accumulated sum. (Answer)
If you would like to solve 26/57 = 849/5x, you can do this using the following steps:
<span>26/57 = 849/5x /*(5x)
</span>26/57 * (5x) = 849 /*57
26 * 5x = 849 * 57 /26
5x = 48393/26 /5
x = <span>48393/(26*5)
x = 372.25
The correct result would be </span><span>372.25.</span><span>

Answer:
145
Step-by-step explanation:
angles in a pentagon add up to equal 540
Hence, 110 + 90 + 80 + 115 + v = 540
( note that we just created an equation that we can use to solve for v )
We now solve for v using the equation created
110 + 90 + 80 + 115 + v = 540
step 1 combine like terms
110 + 90 + 80 + 115 = 395
we now have 395 + v = 540
step 2 subtract 395 from each side
540 - 395 = 145
395 - 395 cancels out
we're left with v = 145
