Solve for p. We are given:

$2m=\frac{p-q}{r}$

To get rid of the fraction on the right, multiply both sides by the denominator, which is r.

$r(2m)=r(\frac{p-q}{r})$

We then get:

$2mr=p-q$

We are solving for p, so add q to both sides to isolate p on the right side. We are then left with:

$2mr+q=p$

You could switch the equation to make it look more traditional. However, both answers are correct.

$p=q+2mr$

Answer:

${x}^{2} - 18x - 21$

Step-by-step explanation:

${x}^{2} + 3 - 6(3x + 4)$

${x}^{2} + 3 - 18x - 24$

${x}^{2} - 21 - 18x$

$\boxed{\green{= {x}^{2} - 18x - 21}}$

Possible Answers: {5, 7, 9, 11, 13}

Let's start with 5.

5-4<8

1<8

So, 5 is CORRECT.

Next, 7.

7-4<8

3<8

So, 7 is CORRECT.

Next, 9.

9-4<8

5<8

So, 9 is CORRECT.

Next, 11.

11-4<8

7<8

So, 11 is CORRECT.

Jamie kicked a soccer ball that traveled along a path described by the parabola y = -x^2 +8x, where y equals the height of the s

andrey2020 [161]

We have that
y = -x²+8x

we know that
when the ball hint the ground is the x-intercepts of the graph
the x-intercepts is for y=0
so
0=-x²+8x--------> x²-8x=0----> x*(x-8)=0

the solution is
x=0
x=8

the x intercepts are the points (0,0) and (8,0)
the distance between the x intercepts points =[8-0]-----> 8 ft

the answer is
8 ft

see the attached figure

What set of reflections would carry rectangle ABCD onto itself?

Furkat [3]

Answer: option D) y=x, x-axis, y=x, y-axis.

I first thought it was the option C) and I tried with it but it was wrong. This is how I dit it.

Option C step by step:

1) Reflection over the x - axis => point with coordinates (a,b) is transformed into point with coordinates (a, -b)

2) Reflection over the line y = x => point with coordinates (a, -b) is transformed into point with coordinates (-b,a)

3) New feflection over the x - axis => (-b,a) transforms into (-b, -a)

4) New reflection over the line y = x => (-b,-a) transforms into (-a,-b)

Which shows it is not the option C).

Then I probed with option D. Step by step:

1) Reflection over the line y = x => (a,b) → (b,a)

2) Reflection over the x-axis => (b,a) → (b,-a)

3) Reflection over the line y = x => (b,-a) → (-a,b)

4) Reflection over the y-axis => (-a,b) → (a,b).

So, this set of reflections, given by the option D) transforms any point into itself, which proofs that the option D) is the right answer.
