Right triangle means Pythagorean theorem!
a^2+b^2=c^2
if each leg (a and b) = x, then
x^2+x^2=c^2
2x^2=c^2
solving for c by taking the square root of both sides leaves

c=x×sqrt(2)

c must be positive since its a length, so no need for a +- I. this case

What is the slope of the line that passes through (-2,7) and (4, 9)? Type a numerical answer in the space provided. If
lord [1]

Answer:

1/3

Step-by-step explanation:

You need to use slope formula. (the change in Y over the change in X = Slope [x1-x2/y1-y2 = slope]). I believe you can also use point slope formula, but I forgot how to do that one.

First, you would set up the equation.

7-9/-2-4 OR 9-7/4+2

you would then solve to get

-2/-6 OR 2/6

when simplified you get

1/3

for both. Hope it helps!

Answer:

  • $0.536

Step-by-step explanation:

<u>Variable: </u>

  • p for pen

<u>Equation:</u>

  • 5(3p + 0.97) = 12.89

<u>Solution:</u>

  • 5(3p + 0.97) = 12.89
  • 15p + 4.85 = 12.89
  • 15p = 12.89 - 4.85
  • 15p = 8.04
  • p = 8.04 / 15
  • p = 0.536
