Answer:

parallel

Step-by-step explanation:

Parallel lines have equal slopes.

Calculate the slopes m using the slope formula

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

with (x₁, y₁ ) = (- 1, 2) and (x₂, y₂ ) = (2, 3)

m = \frac{3-2}{2+1} = \frac{1}{3}

Repeat with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (3, 1)

m = \frac{1-0}{3-0} = \frac{1}{3}

Since slopes are equal then parallel

Write a formula for the function g(x) obtained when the graph of f(x)= square root x is shifted up 1 unit and to the left 9 unit

5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2
Vinvika [58]
5x2y-5x2+3yx2-3y2+x2-y2+8xy2-3y2

First Collect like terms:
5x x 2y, +3x x 2,and +8xy x 2

16x x 2y -4x x 2 - 4y x 2—> Multiply the numbers:

Multiply the numbers 16 x 2

16 x 2 = 32

Now multiply the numbers 4 x 2

4 x 2 = 8

Now Multiply the numbers 4 x 2 again

4 x 2 = 8

= 32xy - 8x- 8y

Factor 8 from the expression


Final Answer:
8(4xy-x-y)

I’m not really sure about my answer but i hope it helps!
Sorry if its wrong..
Stay Safe guys!

Can someone help please
Trava [24]

9514 1404 393

Answer:

  16.4

Step-by-step explanation:

The law of cosines is useful here. It tells you ...

  b^2 = a^2 + c^2 -2ac·cos(B)

  b^2 = 22^2 +10^2 -2·22·10·cos(44°)

  b^2 ≈ 267.49

  b ≈ √267.49 ≈ 16.35514

  b ≈ 16.4
