Answer:

x = -2

Step-by-step explanation:

a parabola  is symmetric (has a mirror image)

a parabola has ONE vertex (a highest or lowest point).

thus a line that goes through the vertex is it's axis of symmetry.

x = 5 , x=99, x=102 are vertical lines that intersect the x axis no matter what the y value is....

your axis of symmetry is a line that looks like  X= SOMETHING

the "something" is the X value of the vertex, which is (-2,3)

this the equation x = -2 is the answer ... see the image

A new car is purchased for 20000 dollars.The value of the cat depreciates at 12.5% per year.What will the value of the car be, t
NemiM [27]

Answer:

$460.38

Step-by-step explanation:

Use the exponential decay formula, y = C(1 - r)^t

Plug in the original price, depreciation rate, and amount of time:

y = 20000(0.875)^11

y = 460.38

So, the car's value after 11 years will be $460.38

Please help! 25 points!<br> Write the equation of a line with slope 3/2 and Y-Intercept -2.
Juli2301 [7.4K]
Hello there!

For this question, we can use slope-intercept form of a line. The following equation is the format for slope-intercept form:
y=mx+b

In this equation, m is the slope and b is the y-intercept. The slope and y-intercept is given. Thus, we just "plug in" the given values into the equation to get our answer. Replace "m" with "3/2" and replace "b" with "-2". After doing so, you get the following equation for the line.

y= \frac{3}{2} x-2

That should be your answer. Hope this helps! :)

How to solve (including answer) x^2+8x+7=0 by factoring
sesenic [268]
Since the first term in the equation is x^{2}, you know that each group you make will have to have an x in it. Now, you need to figure out what times what equals 7 and adds up to 8. You can list all of the numbers that multiply to seven until you find the right numbers.

-1 x -7
1 x 7

1 and 7 add to eight and multiply to seven, so those will be the numbers in your groups. This makes your factored groups (x + 1)(x + 7).
