The slope is 3.

In y=mx+b, the number before x (or m) is the slope.

Is this linear, exponential, or quadratic?

Lady_Fox [76]

Linear. Each increase of 1 in x means a decrease of 3 in y, so it has a consistent slope of -3

What is 3 tens plus 7 tenths plus 8 hundredths as a decimal

Novay_Z [31]

3 tens= 30
7 tenths= 0.7
8 hundredths= 0.08

so 30+ 0.7+0.08= 30.78

If f(1) = 2 – 2 anid 9(37)<br> and g(x) = x2 – 9, what is the domain of g(x) = f(x)?

lana66690 [7]

Answer:

Step-by-step explanation:

Let divide g(x) by f(x)

$\frac{ {x}^{2} - 9 }{2 - x {}^{ \frac{1}{2} } }$

The domain of a rational function cannot equal zero so let set the bottom function to zero.

$2 - x {}^{ \frac{1}{2} } = 0$

$x {}^{ \frac{1}{2} } = 2$

Square both sides

$x = 4$

Also we can simplify the bottom denomiator into a square root function

$2 - \sqrt{x}$

The domain of a square root function is all real number greater than or equal to zero because a square root of a negative number isn't graphable.

So we must find a answer that

Disincludes 4 from the interval
Doesnt range in the negative number or infinity)
Range out in positve infinity
The answer to that is B

Let S be the universal set, where: S={1,2,3,...,18,19,20}

just olya [345]

Answer:

A∪B = {1,2,3,4,5,6,7,8,9,11,13,14,15,16,18,20}

A∩B = {1,5,6,7,8,9,11,14,15}

Step-by-step explanation:

A∪B is the elements in A or B. So, for this question, we just need to find the numbers that are in A or B. Remember not to add anything that is not in set A or B and not write the same number twice.

A∩B is the elements in A and B. Therefore, for this question, we just need to find the numbers which appeared in both set A and B.

Hope this helps :)
