Answer:

[1] 10

[2] 9

[3] j = 3/2 ⋅ s

Step-by-step explanation:

Jada makes sparking juice by mixing 2 cups of sparkling water with every 3 cups of apple juice.How much sparkling water does Jada need if she uses 15 cups of apple juice?

Answer = 10

Explanation:

Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice

2 : 3

Thus also means:

2/3 = x/15

Solve for x:

x = 10

-------------------------------------------------------------------------------------------------------------

How much apple juice does Jada need if she uses 6 cups of sparkling water?

Answer = 9

Ratio for mixing 2 cups of sparkling water with every 3 cups of apple juice

2:3

Also means:

2/3 = 6/x

Solve for x

x = 9

-------------------------------------------------------------------------------------------------------------

Let S represent the number of cups of sparkling water and J represent the number of cups of apple juice. Write an equation that shows how S and J are related. Use your answers from the previous question to assist you with your answer.

What is an equation of the line that passes through the points (0, -4) and (-4, 6)?
olganol [36]

Answer:

The equation of the line is.

y=-\frac{5}{2}x-4

Step-by-step explanation:

Given:

The given points are (0, -4) and (-4, 6)

The equation of the line passing through the points (x_{1},y_{1}) and (x_{2},y_{2}) is.

\frac{x-x_{1}}{x_{2}-x_{1}}=\frac{y-y_{1}}{y_{2}-y_{1}}

Thus, the equation of the line that passes through the points (0, -4) and (-4, 6) is

\frac{x-0}{(-4)-0}=\frac{y-(-4)}{6-(-4)}

\frac{x}{-4}=\frac{y+4}{6+4}

-\frac{x}{4}=\frac{y+4}{10}

-\frac{10x}{4}=y+4

-10x=4(y+4)

-10x=4y+16

4y=-10x-16

The above equation is divided by 2 both sides.

2y=-5x-8

y=-\frac{5}{2}x-4

Therefore, the equation of the line that passes through the points (0, -4) and (-4, 6) is y=-\frac{5}{2}x-4
