Answer:

a = -4, 5

Step-by-step explanation:

You're looking to find points whose limits are equal to -4, which means that they must fufill two requirements:

The values immediately outside the point are pretty much -4
The two sides must both be close to -4.

Additionally, if a point is simply equal to -4, the limit will also be equal to -4.

Dmitry_Shevchenko [17]

Answer:

For the line represented by y = 5 x − 7, the slope is 5 and the

y-intercept is -7.

Step-by-step explanation:

The equation is in Slope-intercept form.

$y=mx+b$

The letter 'm' represents the slope.

The letter 'b' represents the y-intercept.

In the equation $y=5x-7$ :

5 is the slope because it replaces 'm' in the equation. The 'm' is the slope.
-7 is the y-intercept because it replaces 'b' in equation. The 'b' represents the y-intercept.

[Right Triangles Only] Pythagorean Theorem:
$\displaystyle a^2 + b^2 = c^2$

a is a leg
b is another leg
c is the hypotenuse

Step-by-step explanation:

Step 1: Define

Identify given variables.

a = 30

b = 3

c = x

Step 2: Find x

Let's solve for the general equation that allows us to find the hypotenuse:

[Pythagorean Theorem] Square root both sides [Equality Property]:
$\displaystyle \begin{aligned}a^2 + b^2 = c^2 \rightarrow c = \sqrt{a^2 + b^2}\end{aligned}$

Now that we have the formula to solve for the hypotenuse, let's figure out what x is equal to:

[Equation] Substitute in variables:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2}\end{aligned}$
Evaluate:
$\displaystyle \begin{aligned}c & = \sqrt{a^2 + b^2} \\x & = \sqrt{30^2 + 3^2} \\& = \boxed{ \sqrt{909} } \\\end{aligned}$

∴ the hypotenuse length x is equal to √909 and the number under the square root, our answer, is equal to 909.
