Last month, when Joe took his puppy to the veterinarian, the puppy weighed 5.4 pounds. This month, the puppy weighed 7.56 pounds

tino4ka555 [31]

<u>Answer:</u>

40%

<u>Step-by-step explanation:</u>

We are given that last month, Joe's puppy weight 5.4 pounds while this month, the puppy weighed 7.56 pounds.

We are to find the percentage increase of the weight of the puppy

We know that the formula of percentage increase if given by:

<em>Percentage increase = (new value - initial value)/initial value × 100</em>

So substituting the given values to get:

Percentage increase in puppy's weight = $\frac{7.56-5.4}{5.4} \times 100$ = 40%

What is the slope if the line through the points 2/3, 4/7 and 2/3, 11/7

Umnica [9.8K]

The fromula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

We have the points $\left(\dfrac{2}{3},\ \dfrac{4}{7}\right)$ and $\left(\dfrac{2}{3},\ \dfrac{11}{7}\right)$

Substitute:

$m=\dfrac{\frac{11}{7}-\frac{4}{7}}{\frac{2}{3}-\frac{2}{3}}=\dfrac{\frac{7}{7}}{0}\ !!!!$

<h3>Answer: slope is undefined.</h3><h3 />

It's a vertical line: $x=\dfrac{2}{3}$

Solve x^2 – 2x – 15 = 0 using the zero product property.

lawyer [7]

You could just factor out the Trinomial and find the zeros of the equation,

x^2 - 2x -15 = (x - 5)(x + 3) = 0,

x - 5 = 0 and x + 3 = 0, so x = 5,-3 AKA answer choice C
