Answer is B. (−8, −2)

y − x = 6

y + x = −10
...........................add
2y = -4
y = -4/2
y = -2

y − x = 6
-2 - x = 6
-x = 6 + 2
x = 8
x = -8

A percent is a rate in which the first term is compared to ______

PIT_PIT [208]

Answer:

From what we know about percentages and unit rates, the correct options are:

1) 100

2) 1

What is a percent?

Suppose we have an amount A, this would be the 100%.

If we want to know how much a quantity B represents, compared to A, we have:

A = 100%

B = x

where x is a percentage, to find the value of x we compute:

x = (B/A)*100%

While there is a dependence on A, we actually are comparing the term with 100 (because A represents a 100%), so the correct option is A: 100
