The answer would be -6x^2-9x-19

Because firstly you distribute the negative sign

2x^2 -9x-6+-1(8x^2+7+6)

2x^2+-9x+-6-1(8x^2)+(-1)(7)+(-1)(6)

2x^2+-9x+-6+-8x^2+-7+-6

And combine like terms

(2x²-9x-6) - (8x²+7+6)

let us distribute the negative sign over the second bracket first,

2x²-9x-6 - 8x²-7x-6

Now combining like terms

-6x²-16x-12

Answer: 1, 2, 4, or 5

Step-by-step explanation:

The relationship in #3 is a function because all the x values are distinct, that is, none are repeated. (Y values don't matter.)

A function will not repeat any x values so if your goal is for the relationship in #4 to NOT be a function, repeat one of the x values. Any one will work.

Jeremy rides a Ferris wheel. The graph shows h, Jeremy’s height above the ground at any time during the ride. Which inequality r

geniusboy [140]

Answer:

$10 \leq h\leq 50$

Step-by-step explanation:

Jeremy rides a Ferris wheel. The graph shows h, Jeremy’s height above the ground at any time during the ride

Number line represents the height above the ground at any time during the ride.

the shaded part of the graph lies between 10 and 50, also we have solid dot at 10 and 50.

So height of the inequality is

$10 \leq h\leq 50$

Given that QT is an altitude of triangle QRS, measure of angle QTS=(6x+36), and QR = 2x – 5, find QR.

Alexeev081 [22]

We know that
if <span>QT is an altitude of triangle QRS
then
</span><span>the measure of angle QTS is equal to 90</span>°
so
6x+36=90-----> 6x=90-36----> x=54/6
x=9
QR=2x-5-----> QR=2*9-5-----> QR=18-5-----> QR=13

the answer is
QR=13
