Write the equation of a line that is perpendicular to y=0.3x+6 and that passes through the point (3,-8)

Mathematics

Harman [31]3 years ago

<u>First, find the perpendicular slope</u>

y = 0.3x + 6   ⇒ m = 0.3  = \frac{3}{10}

perpendicular slope =  -\frac{10}{3}

<u>Next, input</u> the point (x₁, y₁) and slope (m) into the Point-Slope formula

  y - y₁ = m(x - x₁)

y - (-8) = -\frac{10}{3}(x - 3)

 y + 8 = -\frac{10}{3}x + 10

      y = -\frac{10}{3} + 2

Each serving for a box of trail mix is 3/8 of a cup.
Andrew [12]

Answer:

It's 4

Step-by-step explanation:

It asks how many 3/8 cups are in 1 1/2 cups. So, we divide.

1 1/2 ÷ 3/8. We have to change the 1 1/2 into a improper fraction. 1 1/2 = 3/2. 3/2 ÷ 3/8 = 3/2 ÷ 8/3 = 24/6. Simplify, and you get 4. :)
