Answer:

(2,3)

Step-by-step explanation:

The given equations are:

1st: -3x=42-16y

2nd: 14x=76-16y

Subtract the first equation from the second one:

14x--3x=76-42-16y--16y

14x+3x=34-16y+16y

17x=34

x=\frac{34}{17}=2

We plug in x-value into the second equation to get:

14(2)=76-16y

14x=76-32

28-76=-16y

-48=-16y

Divide both sides by -16

y=3

Use a negative factor to factor the expression - 7a+49b - 35
Helen [10]

Answer:

using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

Step-by-step explanation:

Given the expression

- 7a+49b - 35

Rewrite -35 as 5 · 7

Rewrite 49 as 7 · 7

so

= -7a + 7 · 7b - 5 · 7

as -7 is the common factor, so factoring out

= -7(a-7b+5)

Thus, using a negative facto to factor the expression will be:

- 7a+49b - 35 = -7(a-7b+5)

What is the volume of a cone (in cubic inches) with a radius of 2 inches and a height of 3 inches?
HACTEHA [7]
Hello! The formula for the volume of a cone is πr^2h1/3. That means the volume of the cone is 1/3 of the base (squared radius * height * pi). The radius is 2 inches. 2^2 is 4. The height is 3 inches. 4 * 3 is 12. Pi is an irrational number that repeats, but we can use 3.14 as pi. 12 * 3.14 is 37.68. Keep in mind that this is an answer choice, but it is not the answer. We have to divide that by 3 to find the actual area, because the area of the cone is 1/3 of the base. 37.68/3 is 12.56. There. The volume of the cone is 12.56 cubic inches. The answer is A.
