Which expression is equivalent to (8^2)-4 ??
Tamiku [17]

Answer:

Option C \frac{1}{8*8*8*8*8*8*8*8}

Step-by-step explanation:

we have

(8^{2})^{-4}

Remember that

(a)^{-b} = \frac{1}{a^{b}}

(a^{b})^{c}=(a)^{b*c}

therefore

(8^{2})^{-4}=(8)^{-4*2}=(8)^{-8}

(8)^{-8} = \frac{1}{8^{8}}

\frac{1}{8^{8}}=\frac{1}{8*8*8*8*8*8*8*8}

Answer: Linear

The equation is y = 2x-5

Slope = 2

y intercept = -5

====================================================

Explanation:

Each time x goes up by 1, y increases by 2. This directly leads to a linear equation due to the same rate of change no matter where you are in the table.

The slope is rise/run = 2/1 = 2 because "y increases by 2 each time x increases by 1".

We could use the slope formula to see this. Pick on any two rows to plug in the coordinates. I'll use the last two rows

m = (y2-y1)/(x2-x1)

m = (3-1)/(4-3)

m = 2/1

m = 2

This confirms the slope is 2.

The positive slope means that the line goes uphill as you move from left to right.

---------------

The y intercept is b = -5 because the y intercept always happens when x = 0. This applies to any function, whether it's linear or not.

Together with m = 2 as the slope and b = -5 as the y intercept, we go from y = mx+b to y = 2x-5 as our linear equation

As a way to check, plug in something like x = 1 to find that...

y = 2x-5

y = 2*1-5

y = 2-5

y = -3

The table shows that x = 1 and y = -3 pair up together in the same row, so that confirms x = 1. I'll let you verify the other x values.
