Answer:

x=9

Step-by-step explanation:

because its isosceles, and as stated PQ = QR

solve for x

x=9

Hope you are having a good day!

Answer: x\leq 3

PLEASE MARK ME BRAINLIEST

Step-by-step explanation:

1) Simplify both sides of the inequality:

4x+8\geq 5x+5

2) Subtract 5x from both sides:

4x+8-5x\geq 5x+5-5x

3) Simplify:

-x+8\geq 5

4) Subtract 8 from both sides:

-x+8-8\geq 5-8

5) Simplify:

-x\geq -3

6) Divide both sides by -1:

\frac{-x}{-1} =\frac{-3}{-1}

7) Simplify:

x\leq -3

Which of the following is the equation of a line perpendicular to the line y=-10×+1 passing through the point (5,7)
Juliette [100K]
Y = -10x + 1...slope here is -10. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal of a number, flip the number and change the sign. So our perpendicular line will need a slope of 1/10.

y = mx + b
slope(m) = 1/10
(5,7)....x = 5 and y = 7
now sub and find b, the y int
7 = 1/10(5) + b
7 = 1/2 + b
7 - 1/2 = b
14/2 - 1/2 = b
13/2 = b

so ur perpendicular line going thru (5,7) is y = 1/10x + 13/2
