Need help with number 8
Evgen [1.6K]

The slope-point formula of a line:

y-y_1=m(x-x_1)

We have:

m=2,\ (-8,\ 1)\to x_1=-8,\ y_1=1

Substitute:

y-1=2(x-(-8))\\\\\boxed{y-1=2(x+8)}

What is the median of this set 14, 18, 31, 34, 44, 50
hodyreva [135]
Because there's an even number of values in this set, there is two middle values rather than one (31 and 34). To find the median we need to add them together and divide the sum by 2 (31 + 34 = 65, 65/2= 32.5) Our final answer is 32.5.

Solve the system of equations.<br> y=x+2<br> 4x-4y= 1
Tpy6a [65]

Answer:

No solution

Step-by-step explanation:

  1. 4x - 4y = 1
  2. 4x - 4(x + 2) = 1
  3. 4x - 4x - 8 = 1
  4. - 8 = 1

Our end result is -8 = 1. This is not true, so this system of equations have no solution.

16. Find the length of the median CD.
hodyreva [135]

Step-by-step explanation:

16. Length of a line = sqaureroot of ((x1-x0)^2 - (y1- y0)^2)

C (2,-3) D (6,3)

CD = sqaureroot of ((6-2)^2 + (3-(-3))^2)

CD = sqaureroot of ( 16 + 36)

CD = sqaureroot of 52 = 2 root 13 = length

17. E (5, - 1) because the point is under the x axis.

Midpoint = ((x1+ x0)/2 , (y1 +y0) /2)

B (8,1) C (2, - 3)

Midpoint of BC = ((2+8)/2 , (-3+1)/2)

= (10/2 , - 2/2)

= (5, - 1)

18. Length of AE

A (4,5) E(5,-1)

Square root of ((5-4)^2 + (-1-5)^2)

Square root of (1^2 + - 6^2)

Square root of ( 1 + 36)

Square root of 37 = root 37
