Answer:

step 2 is where she made her mistake

Step-by-step explanation:

- 4x + 1 > 9 ( subtract 1 from both sides )

- 4x > 8

divide both sides by - 4 , reversing the symbol as a result of dividing by a negative quantity.

x < - 2

Answer:

D. There are points on the graph with the same x-coordinate but different y-coordinate.

Step-by-step explanation:

A relation is a function if and only if each element of the range, corresponding with y-axis, is associated with only one element of the domain, corresponding with x-axis. In this case, the graphed relation is not a function, since for all element of the domain, except 0, are related to two distinct elements of the range.

Hence, correct answer is D.

Hey! This is due at like 11 pm!
rewona [7]

Answer:

7

Step-by-step explanation:

Use the Pythagorean Theorem

a^2 + b^2 = c^2

a and b are either opposite or adjacent

c is the hypotenuse.

1. Look for the right angle. (the little box). The right angle "points" to the hypotenuse. In this case, the hypotenuse is 25.

2. Because we know the hypotenuse is 25. We know that 24 is our adjacent. Meaning our missing side is the opposite.

3. Plug in the numbers. 24^2 + b^2 = 25^2

4. Solve:

24^2 + b^2 = 25^2

576 +b^2=625

b^2 = 625-576

b^2 = 49

\sqrt{b^2} = \sqrt{49}

b = 7

Hope this helps! Lmk if you have questions.
