Will give brainliest if correct
goldfiish [28.3K]

Answer:

15) Slope (m) = -7/5

16) Slope (m) = 0

17) Slope (m) = 1/0 (It's an undefined slope, in other words it's just a vertical line)

Step-by-step explanation:

Use this formula for each, to find slope⤵⤵⤵

\frac{y {2} - y1}{x2 - x1}

15) ⤵

\frac{10 - 3}{ - 1 - 4}  =  \frac{7}{ - 5}  =  -  \frac{7}{5}

16) ⤵

\frac{ - 5 - ( - 5)}  {2 - 3} =  \frac{0}{ - 1}  = 0

17) ⤵

\frac{ 3 - 2}{ - 5 - ( - 5)}  =  \frac{1}{0}

Hope this helps :)

8. Solve the formula K = 3M - 7 for M
mamaluj [8]

Answer:

m = \frac{k + 7}{3}

Step-by-step explanation:

k = 3m - 7

k + 7 = 3m - 7 + 7

k + 7 = 3m

\frac{k + 7}{3} = m

(I'm not 100% sure fyi)

Help Math 60points please
Darina [25.2K]

ANSWER:

<u>On solving equation by quadratic formula method, we get</u>

D = b² – 4ac

  • (–5)² – 4 × 1 × 3
  • 25 – 12
  • 13

D > 0, so it has real roots.

Now, x = – b ± √D/2a

  • – 5 ± √13/2

So, <u>Correct choice</u> - [A] & [C].
