The midpoint of GH is (-2, 3), and that point satisfies the equation because

3 = -(-2) + 1
3 = 2 + 1
3 = 3

Answer:

Step-by-step explanation:

If GH has a midpoint M(x, y) then we have to determine whether midpoint M lies on the given line y = -x + 1

Since coordinates of G and H are (-8, 1) and (4, 5) so coordinates of the midpoint M will be

x = \frac{(-8+4)}{2} = -2

and y coordinates of point M will be

y = \frac{(1+5)}{2} = 3

Therefore point M is (-2, 3).

Now we plug in the values of x and y in the given equation.

3 = -(-2) + 1

3 = 3

Hence it is proved that the midpoint M of segment GH will lie on the line y = -x + 1

A. Write the equation ax + b = c in terms of x.
Oksanka [162]

Answer:

x=c/a-b/a

Step-by-step explanation:

ax+b=c

1) Subtract b from both sides:

ax=c-b

2) Divide both sides by a:

x=c/a-b/a

A car dealership has seven cars in the lot. Unfortunately, the keys to the cars have been mixed up. The manager randomly grabs a
Paul [167]
To determine The probability of both of these occurring, you would multiply the probability of each together. So, there is a 1/7 chance of the first salesman getting the right key, and 1/6 chance of the second salesman getting the right key. 1/7 x 1/6= 1/42 chance of both occurring.

If QR=x+29 and PS=x–16, what is the value of x?
Juli2301 [7.4K]

Answer:

  61

Step-by-step explanation:

PS is a midsegment of the triangle, so is half the length of the parallel base segment.

  2PS = QR

  2(x -16) = x +29 . . . . . substitute given expressions

  2x -32 = x +29 . . . . . eliminate parentheses

  x = 61 . . . . . . . . . . . . add 32-x
