Levart [38]

Answer:

you need 6 cups of raisins, 4 cups of granola and 8 cups of blueberries.

Step-by-step explanation:

Step 1: Find how much raisins are needed

For 4.5 cups of fruity granola, we need 1.5 cups of raisins

For 18 cups of fruity granola, we need y cups of raisins

4.5 : 1.5

18 : y

Cross multiply

4.5y = 1.5 x 18

y = 27/4.5

y = 6 cups of raisins

Step 2: Find how much granola is needed

For 4.5 cups of fruity granola, we need 1 cup of granola

For 18 cups of fruity granola, we need y cups of granola

4.5 : 1

18 : y

Cross multiply

4.5y = 18

y = 4 cups of granola

Step 3: Find how much blueberries are needed

For 4.5 cups of fruity granola, we need 2 cups of raisins

For 18 cups of fruity granola, we need y cups of blueberries

4.5 : 2

18 : y

Cross multiply

4.5y = 2 x 18

y = 36/4.5

y = 8 cups of blueberries

Therefore, in order to make 18 cups of fruity granola, you need 6 cups of raisins, 4 cups of granola and 8 cups of blueberries.

Graph the given relation or equation and find the domain and range. Then determine whether the relation or equation is a functio

crimeas [40]

Answer:

The graph is attached.

$Domain:\ All\ Real\ Numbers\\\\Range:\ All\ Real\ Numbers$

The relation is function.

Step-by-step explanation:

Find the x-intercept. Substitute $y=0$ into the equation and solve for "x". Then, this is:

$0=2x+2\\\\x=\frac{-2}{2}\\\\x=-1$

The equation of the line in Slope-Intercept form is:

$y=mx+b$

Where "m" is the slope and "b" is the y-intercept.

In this case "b" is:

$b=2$

Therefore, since the line passes through the points ( $(-1,0)$ and $(0,2)$ , you can graph it. (Observe the graph attached)

Since it is a line, then the relation is a function, and the Domain and the Range of Linear Functions are:

$Domain:\ All\ Real\ Numbers\\\\Range:\ All\ Real\ Numbers$
