Answer:

See Step by step explanation

Step-by-step explanation:

(g+f)(x) = g(x) + f(x) = 7x-1\\(g'f)(x) = g(x)f(x) = (3x-1)(4x) = 12x^{2}-4x\\(g-f)(-2) = -(-2)-1 = 1

George walks to a friend's house. He walks 750 meters North, then realizes he walked too far. He turns around and walks 250 mete
Hunter-Best [27]

What is the slope of a line that has a y-intercept but no x intercept
IRINA_888 [86]

Answer:

The slope of a line that has a y-intercept but no x-intercept will be zero.

Step-by-step explanation:

If the line has no x-intercept, then it never intersects the x-axis, so it must be parallel to the x-axis.

If a line does not have an x-intercept, it means it would never intersect the x-axis.

Thus, it must be parallel to the x-axis, meaning its slope will be zero. It would be just a horizontal line.

For example, y=9 is the line equation that does not have an x-intercept and its slope is zero.

Therefore, the slope of a line that has a y-intercept but no x-intercept will be zero.

How to solve -8+squre root (5a-5)=-3
sertanlavr [38]

Answer:

a=6

Step-by-step explanation:

Given equation:

-8+\sqrt{5a-5}=-3

Solving for unknown variable a

Adding 8 both sides by additive property of equality.

+8-8+\sqrt{5a-5}=-3+8

\sqrt{5a-5}=5

Squaring both sides to remove the square root.

(\sqrt{5a-5})^2=5^2

5a-5=25

Adding 5 both sides by additive property of equality.

5a-5+5=25+5

5a=30

Dividing both sides by 6 to isolate a

\frac{5a}{5}=\frac{30}{5}

∴ a=6
