Answer:
a: x − 2y = −12
Step-by-step explanation:
the standard form of a line is is usually given as Ax + By = C, so just by deduction you can tell that the correct answer is a.
If you want to do the procedure it would be:
y − 3 = 1/2 (x + 6)
y − 3 = 1/2 x + 3
y - 1/2 x = 3 + 3
y - 1/2 x = 6
(y - 1/2 x = 6) * 2 to get rid of the fraction
2y - x = 12 rearrenge the terms
x - 2y = -12
P=2*(5ft +7 ft)
P=2*12 ft
P=24 ft - is the answer
W - a width
3w - a length
27 ft² - an area
Therefore:
w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3
3w = 3 · 3 = 9
width = 3
length = 9
The perimeter:
P = 2 · width + 2 · length
P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.
Answer:

Step-by-step explanation:
<u>Exponential Growing
</u>
Steven currently reads 2 books a year. He wants to triple the number of books read per year. The first year he should read

By the second year, he should read

By the third year, he should read

We can clearly see there is a geometric progression of the number of books he should read for the year n. The general formula is, being B the number of books read at the year n
