Subtract x from both sides and get
x-5>-2
add 5 to both sides
x>3

20 POINTS!!!

Hello from MrBillDoesMath!

Answer:

x = 0, 7

Discussion:

f(g(x)) =

f ( x^2-7x) =

1/ ( x^2 - 7x)

The points NOT in the domain are those where the denominator, x^2 - 7x = 0.

x^2 - 7x = 0 => factor x from each term

x(x-7) = 0 => one or both terms must each 0

x = 0 or x =7

Thank you,

MrB

Find the volume of each solid. Round to the nearest hundredth. Show your work

Answer is 512 cu.ft.
Volume of a cube is length x width x height
So 8 x 8 x 8 = 512

If quadrilateral ABCD rotates 90° counterclockwise about the origin, what are the coordinates of A′ in quadrilateral A′B′C′D′ ?

Georgia [21]

The coordinates of "A" would most likely replace those of "B" or be very close. Brainliest is always appreciated, feel free to ask another question, and Have a nice day!

If a coin is tossed and a number cube is rolled what is the probability of getting heads and the number cube shows 3?

Maurinko [17]

Answer:

1/12

Step-by-step explanation:

Since the probability of getting heads is 1/2 and the probability of the number cube getting three is 1/6, we multiply.

For every coin flip, there is a 1/6 chance of getting a three. But since there is another condition, we have to multiply. Multiplying both fractions make 1/12.

5. (9) Letf- ((-2, 3), (-1, 1), (0, 0), (1,-1), (2,-3)) and let g- ((-3, 1), (-1, -2), (0, 2), (2, 2), (3, 1)j. Find: a. (g f (0

Answer: g(f(0)) = 2 and (f ° g)(2) = -3.

Step-by-step explanation: We are given the following two functions in the form of ordered pairs :

f = {(-2, 3), (-1, 1), (0, 0), (1,-1), (2,-3)}

g = {(-3, 1), (-1, -2), (0, 2), (2, 2), (3, 1)} .

We are to find g(f(0)) and (f ° g)(2).

We know that, for any two functions p(x) and q(x), the composition of functions is defined as

$(p\circ q)(x)=p(q(x)).$

From the given information, we note that

f(0) = 0, g(0) = 2, g(2) = 2 and f(2) = -3.

So, we get

$g(f(0))=g(0)=2,\\\\(f\circ g)(2)=f(g(2))=f(2)=-3.$

Thus, g(f(0)) = 2 and (f ° g)(2) = -3.
