What is the slope? I really suck at math

This is not a function, therefore, the slope is undefined.

I would propose using a VERTICAL LINE TEST. This test is to check vertically if there are more than one coordinates/points in one vertical line. That line is vertical, and there are many points, which makes it not a function. And if it is not a function, then the slope is undefined.

The slope, also, is the average rate of change. The formula you use to find the slope is $\frac{y(2) - y(1)}{x(2) - x(1)}$ . You would take any coordinates and insert them into this formula.

Slope would be undefined because there are many many y-values for one x value. This is impossible for ANY function. To be specific, the correct equation that names the graph is x=4. Please note that this is not a function. If it goes straight up, it is UNDEFINED!!!

Hope I helped!

The answer is D

Barbara deposited $300 in the bank. If the bank pays her simple interest at the rate of 4 percent per year, how much money will

grigory [225]

Answer:

309

Step-by-step explanation:

The formula for simple interest is

A = P(1 + rt)

where A is the amount of money in the account

P is the principal invested

r is the interest rate in decimal form

t is the time invested in years

We know

P = 300

r = 4% = .04

t = 9 months = 9 months * 1 year/12 months = .75 year

Substituting into the equation

A = 300(1 + .04*.75)

=300 (1+.03)

=300(1.03)

= 309

I have to transfer this graph into a vertex form equation, but I'm not sure how to.

tino4ka555 [31]

Answer: y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2

Step-by-step explanation:

vertex form is y=a(x-h)^2 + k

here we can see the vertex is (3,0) which is (x,y). Or (h,k) in this case.

so to plug that into vertex form, we now have y=a(x-3)^2 + 0. or just y=a(x-3)^2.

now we need to find "a" which is the leading coefficient. to do that we can plug in the (6,-6) for the x and y parts of the above equation. so we'd have

-6=a(6-3)^2. which goes to -6=a(2)^2 which is -6=4a. divide each side by 4 to get a = -2/3. plug this in for a

the final equation would be y = -2/3(x-3)^2 + 0 or y = -2/3(x-3)^2
