Answer:

2. m = 1

3. y - (-1) = 5 (x - 4)

4. y = 5x - 21

Step-by-step explanation:

<u>Work for #2</u>

m (slope) = \frac{y2 - y1}{x2 - x1} \fracyx}

m = \frac{-1 - 2}{-2 -1}

m = \frac{-3}{-3}

m = 1

<u>Work for #3</u>

y = -1/5x + 3 and through (4, -1)

The slope of a perperndicular line is the negative reciprocal. So, it is 5.

Plug this number into point-slope form. Use the points you were given (4,-1) in the equation as well.

y - y1 = m (x - x1)

y - (-1) = 5 (x - 4)

y + 1 = 5x - 20 (Only if you are supposed to simplify it)

<u>Work for #4</u>

Finish solving the equation

y - (-1) = 5 (x - 4)

y + 1 = 5x - 20

y = 5x - 20 - 1

y = 5x - 21

Two glasses of milk and three snack bars have a total of 72 carbs. and 4 glasses of milk and 2 snack bars have a total of 88 car
melisa1 [442]

Answer:

one glass of milk = 15 carbs

one bar = 14 carbs

Step-by-step explanation:

let 'm' = one glass of milk

let 'b' = one snack bar

system of equations:

2m + 3b = 72

4m + 2b = 88

I used the elimination method and multiplied the 1st equation by -2

  -4m - 6b = -144

+  <u>4m + 2b =  88</u>

           -4b = -56

              b = 14

now solve for 'm'

2m + 3(14) = 72

2m + 42 = 72

2m = 30

m = 15
