Answer:

D and E

Step-by-step explanation:

f(x) = (x - 3)² - 25

x intercepts occur when y = 0

0 = (x - 3)² - 25

25 = (x - 3)²

±5 = x - 3

x = 8, or -2

A) g(x) = 2x + 2  

       0 = 2x + 2

        x = -1  Nope

B) h(x) = 2x + 6

       0 = 2x + 6

       x = -3 Nope

C) q(x) = -4x + 11

       0 = -4x + 11

        x = 11/4  Nope

D) r(x) = -3x - 6

       0 = -3x - 6

        x = -2   YES

E) w(x) = 3x - 24

       0 = 3x - 24

       x = 8   YES

Which number line shows the solution set for StartAbsoluteValue 8 minus 2 p EndAbsoluteValue = 6?
Illusion [34]

Answer:

A number line going from negative 1 to positive 7. Points are at positive 1 and positive 7.

Step-by-step explanation:

We have the equation:

|8 - 2*p| = 6

Remember that the equation:

|f(x)| = A

with A > 0

means that:

f(x) = A

or

f(x) = -A

Then for our case, we can rewrite:

|8 - 2*p| = 6

as:

(8 - 2*p) = 6

or

(8 - 2*p) = -6

Now we can solve these two equations to find the two possible values of p.

From the first one, we get:

8 - 2*p = 6

8 - 6 = 2*p

2 = 2*p

2/2 = p = 1

so one solution is  p = 1

Now from the other equation, we can get the other solution:

(8 -2*p) = -6

8 - 2*p = -6

8 + 6 = 2*p

14 = 2*p

14/2 = p = 7

So the two solutions are p = 1 and p = 7

Then the correct option is:

"A number line going from negative 1 to positive 7. Points are at positive 1 and positive 7."

Please help with this
Sergeeva-Olga [200]

Answer:

33.3 pounds

Step-by-step explanation:

Alright, so if she made a 100 percent on the gloves, then she sold them for 8 dollars, because 4 + 1.00(4) = 8.

48 - 8 = 40

She sold the skirt for 40 dollars, and if that's at a 20 percent profit, then we can do a proportion

\frac{40}{1.20} = \frac{x}{1.00}

If we solve for x, we figure out that x = 33.33333 repeating.

So out answer to the nearest decimal place is 33.3 pounds

Rewrite the following equation into the slope-intercept form y=mx+b.<br> y- 5 = -3(x - 12)
Norma-Jean [14]

Answer:

y = -3x + 41

Step-by-step explanation:

All you need to do is expand everything and solve for y.

y- 5 = -3(x - 12)

y - 5 = -3x + 36

y = -3x + 41

I hope this helped!
