The answer is the third one aka C.

There must not be two points on the same y-axis because that doesn't make a function but a relation instead.

C. doesn't have 2 points on same y-axis and therefore the third picture is the relation that's a function.

Answer:

Step-by-step explanation:

For the function $y=-5x$ , all coordinates this line passes through should make this inequality true.

$\begin{case}y=5(-7)=35\\y=-2(-5)=10\\y=2(-5)=-10\end{case}$

This corresponds with table B.

Answer:

Step-by-step explanation:

ΔABC is congruent with ΔDEF. That means the corresponding sides are congruent.

Look at the order of the letters. EF are the last two letters of ΔDEF. So this corresponds with the last two letters of ΔABC. Therefore, EF ≅ BC.

EF ≅ BC

x² + 8x = 48

x² + 8x − 48 = 0

(x + 12) (x − 4) = 0

x = -12 or 4

Since x can't be negative, x = 4.

Renata and her family go through an average of more than 15 cans of sparkling water each day. They buy cases of 24 cans at $3.50

DENIUS [597]

Answer:

The inequality required to express the above condition is x ≥ 18.75

Step-by-step explanation:

Renata and her family go through an average of more than 15 cans of sparkling water each day.

The number of cases of 24 cans of sparkling water.

We can take the number of cases to be x.

Each case is said to cost $3.50.

An inequality for the number of cases that Renata's family go through in 24 days can be written as

x ≥ $\frac{15 \times 30}{24}$ ⇒ x ≥ $\frac{450}{24}$ ⇒ x ≥ 18.75

Therefore the inequality required to express the above condition is

x ≥ 18.75
