Answer:

Ben is incorrect

The solutions are x>-3 and x < 3

Step-by-step explanation:

we have

$-x^{2} +9 > 0$

Multiply by -1 both sides

$x^{2} -9 < 0$

Adds 9 both sides

$x^{2} < 9$

The solutions are

$x < 3$

and

$-x < 3$ -----> Multiply by -1 both sides ----> $x > -3$

therefore

The solution is the interval (-3,3)

Quiana has 5 times more text messages from Yolanda than from Pierre. Quiana has 30 text messages from Yolanda. Which equation ca

VladimirAG [237]

Answer:

$p=\frac{30}{5}$

Step-by-step explanation:

Quiana has 5 times more text messages from Yolanda than from Pierre, we also know that she actually has 30 text messages from Yolanda. In other words, 30 texts from Yolanda is 5 times more text messages than from Pierre.

Thus, if we call p the number of texts messages from Pierre we would have that

$p=\frac{30}{5}$ (since 30 texts from Yolanda is 5 times more than p, we can divide by 5 to find p)

And if we solve this equation we would get that Quiana has 6 text messages from Pierre
