This is a trial and error answer.

Suppose that QT = -3, then

x + 2 = y

2x = y + 3

Apply substitution,

2x = (x+2) + 3

2x = x + 5

x = 5

y = 7

chek your answer,

Can somebody help me with this one. It says use the vertical line test to determine which graph represents a function
sineoko [7]

Answer:

Only option C shows a function

Step-by-step explanation:

The vertical line test is a visual way to determine if a curve is a graph of a function or not. A function can only have one output, y, for each unique input, x. This means that a vertical line made in the domain of the function can crosses the curve of the function only once. If it crosses the curve of the function more than once, then the curve is not a function.

In option A, a vertical line would cross two values, so it is not a function.

The curve of option B is a vertical line itself, so a vertical line would intersect an infinite amount of points; then it is not a function.

Option C is a function because a vertical line would only intersect the function's curve (which is a line) once.

A recipe calls for 1/2 cup of celery,2 1/3 of water and 3/4 cups of carrots. What the combined amont of these three ingredients?
lys-0071 [83]

Answer:

43/12

Step-by-step explanation:

First we must find a common denominator for all 3 fractions, 1/2 cup, 2 1/3 cup, and 3/4 cup all share 12 as a common denominator.

However, let's convert 2 1/3 cup into an improper fraction: there are 2 (3/3 cups) here multiply (3/3) and (2/1) you get 6/3. Finally, add the remaining 1/3 to 6/3 and you get 7/3.

Now, to get all these fractions to have the same common denominator.

(1/2) ×(6/6)=(6/12)

(7/3)×(4/4)=(28/12)

(3/4)×(3/3)=(9/12)

Add them all together and your answer is: (43/12)

The population of a town is currently 32,000 and it is projected to increase by 5% each year. What would be the population in 4
BabaBlast [244]
You would multiply 32,000 x 0.05 = 1,600 so
1,600 x 4 = 6,400
So the population would grow by 6,400 every 4 years.
