Mathematics
1 answer:
Goshia [24]2 years ago
4 0

Answer:

Slope (m) = \frac{y}{x} = \frac{2}{3} = 0.66666666666667

Step-by-step explanation:

0 = arctan (\frac{y}{x}) = 33.69006752598°

X = 4 – 1 = 3

Y = 4 – 2 = 2

Distance (d) = \sqrt{x^2+y^2}= \sqrt{13} =3.605551275464

Equation of the line:

y = 0.66666666666667x + 1.3333333333333

or

y=\frac{2}{3}x+\frac{4}{3}

When x=0, y = 1.3333333333333

When y=0, x = -2

So the answer would be A. I had a bit of trouble figuring this out, but then I went to Order of Operations and found it out. 

So you fill in n, and I just used 9 since it's in the question. So then, subtract 1 from 9, giving you 8. Then you multiply 0.35 by 8, giving you 2.8. Now lastly, add 7.51, and you get 10.31

I hope this helps you! If it does, please rate as Brainliest :D

Use the X method to find the solutions of<br> 62 + 2x - 20 = 0.
inysia [295]

Answer:

x = -21

Step-by-step explanation:

62 + 2x - 20 = 0.

Combine like terms

42 +2x =0

Subtract 42 from each side

42-42 +2x = 0-42

2x = -42

Divide each side by 2

2x/2 = -42/2

x = -21
