PLEASE HELP!!! What is the slope parallel to 5x + y = 3, please show me step by step, will give the brainliest for this answer.

Andreas93 [3]

Answer:

-5

Step-by-step explanation:

First, put the equation into the form y = mx +b (where m is the slope and b is the y-intercept)

This would look like:

$5x + y = 3\\y = -5x + 3$

This means the slope is -5.

Parallel lines always have the same slope, so the slope of the parallel line is also -5

If the population of a certain city increased 25% in two years, the new population was what percent of the old?

disa [49]

Answer:

125%

Step-by-step explanation:

This because if in origin the city was made up for example by 100,000 people, that was the 100% of the city. Now you add the 25% in two years and the city will be made by 125,000 people. So 100%+25%=125%. 

I think it's right

Part A: Clancey and Ethan are starting new books. So far, Clancey has read 1/4 of his book, which has 240 total pages and Ethan

Nonamiya [84]

In order to find who has read more pages, let's find the number of pages read by each one.

The number of pages read by Clancey is:

$\frac{1}{4}\cdot240=\frac{240}{4}=60$

The number of pages read by Ethan is:

$\frac{2}{5}\cdot170=\frac{340}{5}=68$

So Ethan read more pages.

The combined number of pages in both books is 240 + 170 = 410.

The combined number of pages read is 60 + 68 = 128

So the fraction is:

$\frac{128}{410}=\frac{64}{205}$

If f(x) = 2x – 6 and g(x) = x – 22, find each value.

Charra [1.4K]

Answer:

Step-by-step explanation:

I think you made a typo. g(x) should equal x - 2 not x - 22

g(x) = x - 2

g(-1) = -1 - 2

g(-1) = - 3

The answer is d. Otherwise there is no answer.
