Answer:

k = 4

Step-by-step explanation:

-9 +8k = 7+4k

Subtract 4k from each side

-9 + 4k = 7

Add 9 to each side

4k = 16

Divide by 4

k = 4

Plug in the value you got for k:

-9 + 8(4)  ?  7 + 4(4)

-9 + 32  ?  7 + 16

23  ? 23

23 = 23

The vertices of triangle PQR are P(10,-6), Q(6,2), & R(4,-1). Describe a translation that places the image of the triangle e
Gnoma [55]

Answer:

Translate 7 units up and then translate 11 units to the left.

Step-by-step explanation:

We have the triangle PQR having co-ordinates (10,6), (6,2) and (4,-1).

It is required to translate ΔPQR so that the resulting image is completely inside the 2nd quadrant.

So, for that we will apply the following sequence of translations:

1. Translate 7 units up.

This will give us the figure in the 1st quadrant having co-ordinates (10,1), (6,9) and (4,6).

2. Translate 11 units to the left

We will get the final triangle P'Q'R' with the co-ordinates P'(-1,1), Q'(-5,9) and R'(-7,6) as shown below.

Solving Quadratic Equations: Factoring
Radda [10]

Answer:

The factored form of the equation is (x+4)(x-6)=0.

Step-by-step explanation:

Because (x-4)(x+2)=x^2-4x+2x-8=16,

so that means x^2-2x-8=16,

move 16 to the other side,

you get x^2-2x-8-16=0,

simplify,

you get x^2-2x-24=0,

which satisfies (x+4)(x-6)=0 when factored out.

Because (x+4)(x-6)=x^2+4x-6x-24=x^2-2x-24=0.
