Which of the following graphs represents the equation y -4 =3 (x-1)

1 answer:

6 0

To start, we can factor the "3" in the parentheses - then move the -4 over. So,

y - 4 = 3x - 3
y = 3x + 1

So the y-intercept of the equation is "1", and the slope is 3.

Put x=37-y in eqn 2

5.5(37-y)+13.5y=355.5

203.5-5.5y+13.5y=355.5

A sports magazine prints 12 issues per year, and a technology magazine prints 10 issues per year. The total number of pages in a

Evgesh-ka [11]

Answer:

$s=t-18...(1)$

$12*s=10*t+32...(2)$

Step-by-step explanation:

Let s be the number of pages in each issue of the sports magazine, and t be the number of pages in each issue of the technology magazine.

We have been given that Each issue of the sports magazine has 18 fewer pages than each issue of the technology magazine. We can represent this information in an equation as:

$s=t-18...(1)$

We are also given that sports magazine prints 12 issues per year, so the total number of pages in all the issues of sports magazine will be 12*s.

We are given that a technology magazine prints 10 issues per year, so the total number of pages in all the issues of technology magazine will be 10*s.

Further, the total number of pages in all the issues of the sports magazine for one year is 32 more than the total number of pages in all the issues of the technology magazine for one year.

We can represent this information in an equation as:

$12*s=10*t+32...(2)$

Therefore, our desired system of equations will be:

$s=t-18...(1)$

$12*s=10*t+32...(2)$

What is the range of the function on the graph

grigory [225]

The answer is the last answer choice:
all the real numbers greater than or equal to -3

The range of a function is all the possible y values of a function. From the function you see on the left side, it shows that the minimum value is at (2, -3) and from there it doesn't go any lower meaning all the values will be higher than -3 for the y value.
