Answer:

Step-by-step explanation:

Here, x² + 13x = -3

Here, as x² + 13x would remain same, you have to add or subtract equivalent number from both sides,

x² + 13x + 3 = 0

Option C: $\frac{4}{5}$ is the slope of the line

Explanation:

The line passes through the points $(3,-1)$ and $(-2,-5)$

We need to find the slope of the line.

The slope can be determined using the formula,

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

Where the coordinates $(x_1,y_1)$ and $(x_2,y_2)$ are $(3,-1)$ and $(-2,-5)$

Let us substitute the points in the formula

Thus, we have,

$m=\frac{-5-(-1)}{-2-3}$

Simplifying, we get,

$m=\frac{-5+1}{-2-3}$

Adding the numerator and denominator, we have,

$m=\frac{-4}{-5}$

Cancelling the negative terms, we get,

$m=\frac{4}{5}$

Thus, the slope of the line is $m=\frac{4}{5}$

Therefore, Option C is the correct answer.

Answer: b

Step-by-step explanation:

In the last question, you wrote on a second equation "13x ...." kkk

Let's go:

We have to check each one answer in the following system:

x - 2y = 7

3x + 7y = 8

I can use the substituition method to solve this system...

x = 7 + 2y

3x + 7y = 8

3(7 + 2y) + 7y = 8

21 + 6y + 7y = 8

13y = 8 - 21

13y = -13

y = -1

x = 7 + 2.(-1)

x = 5

Finally, the correct answer is the second one (letter b).
