You have to get a common denominator so

3 x 3 = 9
5 x 3 = 15

So now we have 9/15 + 4/15 which is 13/15.

The answer is 13/15

Which of the following pairs of functions are inverses of each other?

Serggg [28]

Answer:

The answer is (B).

Step-by-step explanation:

A). y = f(x) = 6(x - 2) + 3 ⇔ y = 6x - 12 + 3 ⇔ 6x = y + 9 ⇔ x = $\frac{y+9}{6}$

g(x) = $\frac{x+9}{6}$ is inverse function of f(x) and ≠ $\frac{x+2}{6}$ - 3

B). y = f(x) = $\frac{5x}{4}$ - 3 ⇔ 4y = 5x - 12 ⇔ x = $\frac{4y+12}{5}$

g(x) = $\frac{4(x + 3)}{5}$ is inverse of f(x)

Which equation is in point-slope form for the given point and slope?

faust18 [17]

Answer: y-7 = 4(x+3), choice B

============================================

Point slope form is generally

y-y1 = m(x-x1)

we have m as the slope and (x1,y1) as the point this line goes through. In this case,

m = 4

(x1,y1) = (-3,7) so x1 = -3 and y1 = 7

So,

y-y1 = m(x-x1)

y - 7 = 4(x - (-3))

y - 7 = 4(x + 3)

which is why choice B is the answer

Trevor is making 2/3 of a recipe for chicken noodle soup. He adds ½ cup of chopped celery. The equation 2/3 c = 1/2 can be used

Nikitich [7]

Answer:

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$

Step-by-step explanation:

Given that:

Trevor is making 2/3 of a recipe

Number of cups of chopped celery used = 1/2 cup

The following equation can be used to find the original number of cups of chopped celery used in recipe.

$\frac{2}{3}c=\frac{1}{2}$

Multiplying both sides by 3/2

$\frac{3}{2}*\frac{2}{3}c=\frac{1}{2}*\frac{3}{2}\\\\c= \frac{3}{4}\\$

Hence,

Cups of chopped celery in original recipe = $\frac{3}{4}\ cups$

solmaris [256]

Answer:

The expression contains FOUR terms and each term contains TWO factors.

Step-by-step explanation:

In algebra, the word term refers to single numbers(10), variables(y) also the product of the two(10y).

In the given expression : ab+cd+ef+gh .

We have four terms;

A factor is part of a product. For the given equation we Four terms each term will have two factors.

ab- is a product of factor a and b
cd- is a product of factor c and d

ef-is a product of factor e and f
gh-is a product of factor g and h
