Answer:

D) y = -2x - 4

Step-by-step explanation:

Use the points:

The y- intercept is - 4 and the slope is:

m = (-4 - 0)/(0 - (-2)) = -2

The line is:

y = -2x - 4

Correct choice is D

help please !!!Kevin wants to make a mixture that is 50% lemon juice and 50% lime juice. How much 100% lemon juice should he add

Liula [17]

So basically, he wants to make mixture where lemon=lime

it is 6 gallons so
40% of 6=0.4 times 60=2.4=lemon
60% of 6=0.6 times 60=3.6=lime
so to make them equal
3.6-2.4=1.2
he must add 1.2 gallons of 100% lemon juice to make a mixture of 50% lemon and 50% lime

1.2 gallons is the answer

A recipe calls for 2/3 cup of sugar for every 4 teaspoons of vanilla. What is the unit rate in teaspoons per cup?

Setler [38]

Divide the number of teaspoons by the number of cups.

$\dfrac{4~teaspoons}{\frac{2}{3}~cup} =$

$= \dfrac{4}{1} \div \dfrac{2}{3}~\dfrac{teaspoons}{cup}$

$= \dfrac{4}{1} \times \dfrac{3}{2} ~\dfrac{teaspoons}{cup}$

$= 6 ~\dfrac{teaspoons}{cup}$
