Answer:

y = 2(x+3)^2 - 17

Step-by-step explanation:

y = 2x^2+12x+1

y = 2(x^2+6x) + 1

y = 2(x^2+6x+9) + 1 - 2(9)

y = 2(x+3)^2 - 17

Show the work for INVERSE, thank you. I got 17 but I did it wrong because it has to be 7

12 - x = 5

Subtract 12 from both sides

12 - 12 - x = 5 - 12

- x = - 7

Divide both sides by -1

-x/-1 = -12/-1

x = 7

Write a scenario that could be represented by this equation: 3/4x = 12

Aneli [31]

Answer:

x=1 or x=16

Step-by-step explanation:

3/4x = 12 or 0.75x = 12

3/4x/3/4 = 12/3/4 or 0.75x/0.75 = 12/0.75

x=12/1 / 3/4

x= 4/4

x = 1 or x = 16

An auto parts store is examining how many items were purchased per transaction at the store as compared to their online website.

anastassius [24]

Answer:

0.4394

Step-by-step explanation:

given that an auto parts store is examining how many items were purchased per transaction at the store as compared to their online website

The data is shown below:

Frequency Frequency*Midpt

Midpt Online Total Online Total

1-3 2 40 147 80 294

4-6 5 60 103 300 515

7-9 8 15 32 120 256

10-12 11 5 18 55 198

120 300 555 1263

Thus we find total items purchased on line = 555

and total items overall purchased = 1263

Hence the probability that a randomly selected item was purchased online

= $\frac{555}{1263} \\=0.4394$

A triangle has one angle that measures 11 degrees, one angle that measures 47 degrees, and one angle that measures 122 degrees.

agasfer [191]

Answer:

obtuse

Step-by-step explanation:

The largest angle is more than 90°, so the triangle is called an "obtuse" triangle.

Here are the classifications based on the measure of the largest angle:

< 90° -- acute triangle

= 90° -- right triangle

> 90° -- obtuse triangle . . . . . like the one in this problem statement
