probability of drawing ace: 4/52 = 1/13

probability of drawing 9: 4/52 = 1/13

probability of drawing ace or 9: 1/13 + 1/13 = 2/13 or ~15.4%

Set up a ratio:

12/24 = x/9

Cross multiply:

24x = 108

Divide both sides by 24:

X = 4.5

Upperloaf Bakery is baking loaves of cornbread and poppy-seed blueberry cake. The recipe for one loaf of corn bread calls for 2
swat32

Answer:

2.25c + 1.75p ≤ 28

1.25c + 2.125p ≤ 30

Step-by-step explanation:

Write a system of two inequalities to model loaves of bread and

cake that can be baked.

let

number of cornbread loaves = c

number of poppy-seed blueberry Cake loaves = p

corn bread

cups of flour = 2 1/4 = 2.25

teaspoon of baking soda = 1 1/4 = 1.25

One loaf of poppy-seed blueberry cake

cups of flour = 1 3/4 = 1.75

teaspoons of baking soda = 2 1/8 = 2.125

The bakery has 28 cups of flour and 30 teaspoons of baking soda in stock.

Quantity of flour to use

c(2.25) + p(1.75)

Quantity of baking soda to use

c(1.25) + p(2.125)

The inequality is

c(2.25) + p(1.75) ≤ 28

c(1.25) + p(2.125) ≤ 30

Alternatively,

2.25c + 1.75p ≤ 28

1.25c + 2.125p ≤ 30

Write the point-slope form of an equation for a line that passes through the point with the given slope (–6, –6), slope = -4/7
djverab [1.8K]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - \frac{4}{7} and (a, b) = (- 6, - 6), hence

y - (- 6) = - \frac{4}{7} (x - (- 6) ), that is

y + 6 = - \frac{4}{7}(x + 6) ← c or d
