romanna [79]

Answer:

11x+y = -28

Step-by-step explanation:

We have two points so we can find the slope

m = (y2-y2)/(x2-x1)

   = (-6-5)/ (-2--3)

   = -11(-2+3)

   = -11/1

The slope is -11

We can use point slope to make an equation

y-y1 = m (x-x1)

y-5 = -11(x--3)

y -5 = -11(x+3)

Distribute

y-5 = -11x-33

Add 5 to each side

y-5+5 = -11x-33+5

y = -11x-28

Add 11x to each side

11x+y = -11x+11x-28

11x+y = -28

This is the standard form of a line

PLEASE HELP! I will give you the brainiest and A LOT of points! (Ch.5.3)
bearhunter [10]

Answer:

Multiplier = 1.75x (7/4).

7/8 cups butter, 4 and 3/8 ounces chocolate, 1 and 3/4 cups sugar, 7/8 teaspoons vanilla, 3 and 1/2 eggs (4 if rounded!), 1 and 5/16 cups flour.

Step-by-step explanation:

The ingredient list is for 16 brownies, but you need to make 28. This means you have to make 1.75x the amount (28/16), so all ingredient quantities need to be multiplied by 7/4 (1.75 in fraction form).

Butter: 1/2 * 7/4 = 7/8 cups

Chocolate: 5/2 * 7/4 = 4 and 3/8 ounces

Sugar: 1 * 7/4 = 1 and 3/4 cups

Vanilla: 1/2 * 7/4 = 7/8 teaspoons

Eggs: 2 * 7/4 = 3 and 1/2 eggs (if rounded, 4, as 3.5 rounds up)

Flour: 3/4 * 7/4 = 1 and 5/16 cups
