Answer:

Option (a)

Step-by-step explanation:

Slope of a line passing through two points $(x_1,y_1)$ and $(x_2,y_2)$ is given by,

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

Slope of the line passing through (-4, 3) and (6, 3) will be,

m = $\frac{3-3}{6+4}$

m = 0

In other words, slope of any line parallel to x-axis is zero.

Therefore, Option (a) is the answer.

Solve x^2 +14x=15 by completing the square

ivanzaharov [21]

Answer:

x = -15 and x = 1

Step-by-step explanation:

Since we have to use the complete the square method, we first need to <u>rewrite the equation</u> in the form $x^{2}+2ax+a^{2}=(x+a)^{2}$ .

This results in $x^{2} + 14x + 7^{2} = 15 + 7^{2}$ .

Next, we <u>simplify the equation</u> to get $x^{2} +14x+7^{2} = 64$ .

<u>Factoring </u>the left side gives us $(x+7)^{2} = 64$ .

Finally we <u>solve the equations</u>: $x+7=\sqrt{64}$ and $x+7=-\sqrt{64}$ .

This gives us x=1, and x=-15
