Graph 24x+25=−6y+7

1 answer:

6 0

When you isolate the y on one side, the slope intercept form of the line is
$y = - 4x - 3$
Two plot point examples would be (0, - 3) (which is the y intercept) and (1, -7)

The Average cost of a long distance call in the USA was 31 cents per minute in 1978 and 8 cents in 2008. Find the approximate pe

olya-2409 [2.1K]

Answer:

74%

Step-by-step explanation:

We have been given that the Average cost of a long distance call in the USA was 31 cents per minute in 1978 and 8 cents in 2008.

We will use percent decrease formula to solve our given problem.

$\text{Percent decrease}=\frac{\text{Initial}-\text{Final}}{\text{Initial}}\times 100\%$

$\text{Percent decrease}=\frac{31-8}{31}\times 100\%$

$\text{Percent decrease}=\frac{23}{31}\times 100\%$

$\text{Percent decrease}=0.741935483\times 100\%$

$\text{Percent decrease}=74.1935483\%$

$\text{Percent decrease}\approx 74\%$

Therefore, there is an approximate 74% decrease in cost per minute for the long distance call from 1978 to 2008.

16 is divided by the sum of a number q and 1. The result is 4. What is the number?

GaryK [48]

16/(q+1)=4
16/(q+1)=4 > Mult. both sides by (q+1)
16=4q+4 > Subtract 4 from both sides.
12=4q > Div. both sides by 4
q=3
