Help meee will give brainly! Find the domain of the function f(x)=5x−9 . DONT SAY I DONT KNOW

Mathematics
1 answer:
Agata [3.3K]2 years ago
7 0

Answer and Step-by-step explanation:

\frac{5}{x-9}

The domain is all real numbers <u>except</u> 9 (positive)

This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is <u>not</u> included.

Ian needs to save at least $85.00 for a new pair of basketball shoes. He has $25.00 in his piggy bank, and can save $12.00 from
sweet [91]

Answer:

x = 6; 6 weeks

Step-by-step explanation:

Hi!!

Okay, so here is the equation needed to solve:

85.00 = 25.00 + 12.00x

Subtract 25 from both sides

85 -25 = 25 - 25 + 12x

Then, you get:

55 = 12x

Divide 55 by 12

55/12 =x

so x = 6

Hope this helps!

The coordinates of the points below represents the vertics of a rectangle
Tanya [424]

Not sure what the question is, but I'm guessing you want to find out the area of the rectangle.

The distance between points P and Q is 4.

The distance between points Q and R is 3.

So the area is 3 * 4 = 12.
