Answer:

Not a function.

Does not pass vertical line test.

Step-by-step explanation:

Something called a vertical line test is used to determine if a relation that has been graphed is a function or not.

We say if it passes then it is a function.

It will pass if you are able to draw infinitely many vertical lines covering the whole graph and each vertical line either touches your relation once or none.

If a single vertical line that you draw touches more than once, then it isn't a function.

When I say draw, I don't mean you should physically do it, but more so imagine it.

Now this particular relation is not a function because I can find a vertical line that touches more than once. Take the vertical line x=5 for example.

It will touch at (5,-6) and (5,6). You cannot have an x assigned to more than one y.

Jimmy paid off a mortgage by paying $775 per month for 12 years. What was the original amount of the mortgage if the interest ra

valentinak56 [21]

Answer:

The original amount of the mortgage was $66231.45.

Step-by-step explanation:

In order to find the original amount of the mortgage, you can use the following formula to calculate the present value:

PV=FV/(1+r/n)^nt

PV=present value

FV=future value= 775*12*12=111.600

r=rate of interest=0.0440

n= number of compounding periods= 2

t= time in years=12

Now, you can replace the values on the formula:

PV=111600/(1+(0.0440/2))^2*12

PV=111600/(1.022)^24

PV=111600/1.685

PV=66231.45

According to this, the answer is that the original amount of the mortgage was $66231.45.

What’s the equation in slope-intercept form?

Varvara68 [4.7K]

You can take any 2 points from the table and calculate the slope, as follows:
-2-(-4) 2
m = slope = ---------- = ------ = -1/5
-5 - 5 -10
The slope-intercept form is y = mx + b. You already know m (which is -1/5), and have several points from which to choose to obtain x and y. Let's use the given point (-2, -1).

Then -1 = (-1/5)(-2) + b, or -1 = 2/5 + b. Solve for b.

-5 = 2 + 5b, so 5b = -7, and b = -7/5.

The desired equation is y = (-1/5)x - 7/5.

Escape park owner was 30% of each order to include long boards he wants to know how many long boards to order out of a total of

Nataliya [291]

Answer:

He should order 15 long boards

Question:

Escape park owner want 30% of each order to include long boards he wants to know how many long boards to order out of a total of 50 skateboards

Step-by-step explanation:

Let x and y represent the number of long board and the total number of skateboard to order.

Given that 30% of each order to include long boards;

x = 30% of y

x = 0.3y .....1

But, the total number of skateboard is given as 50

y = 50

From equation 1

x = 0.3y = 0.3(50)

x = 15

He should order 15 long boards

What is the domain of the function f(x) = 2x^2 - 3?

SpyIntel [72]

Domain: Set of all real numbers

If you want to express the domain in set-builder notation, then you'd write something like $\left\{x|x\in\mathbb{R}\right\}$ which is fancy notation to basically say "x is any real number"

If you want to write the domain in interval notation, then you'd write $\left(-\infty, \infty\right)$ which is the interval from negative infinity to positive infinity. In other words, the entire real number line.

-----------------------------------------------------------------

The domain is the set of all real numbers because we don't have any restrictions to worry about. There are no division by zero errors. There are no cases where we have to worry about taking the square root of a negative number, or anything similar. Any number can replace x to generate an output for y.
