Answer:

(-1,-4)

Step-by-step explanation:

We shall substitute them in and see

y =4x

(1,3)

y =4(1) = 4 That is not 3 Not a solution

(-1,-4)

y = 4(-1) = -4 This is a solution

(-4,-1)

y = 4(-4) = -16 This is not -1 Not a solution

(1,-4)

y = 4(1) = 4 This is not -4 Not a solution

To make caffe mocha, LaVelle uses one ounce of chocolate syrup,and five ounces of coffee

To make 6 ounces of caffe mocha (one ounce of chocolate syrup plus 5 ounces of coffe), LaVelle uses one ounce of chocolate syrup,and five ounces of coffee

using proportion

Find out how many ounces of coffee does she need to make 48 ounces of caffe mocha

Let

x ---> ounces of coffee needed to make 48 ounces of caffe mocha

$\frac{6}{5}\ \frac{oz\ caffe\ mocha}{oz\ coffee} =\frac{48}{x}\ \frac{oz\ caffe\ mocha}{oz\ coffee}\\\\x=48(5)/6\\\\x=40\ oz\ coffee$

liq [111]

Answer:

y = 2x - 3

Step-by-step explanation:

y = mx + b

m = (y2-y1)/(x2-x1)

m = (3-(-3))/(3-0)

m = 6/3

m = 2

y = mx + b

y = 2x + b

3 = 2(3) + b

3 = 6 + b

b = -3

therefore

y = 2x - 3
