9 to the 12th power divided by 9 to the 8th power

1 answer:

6 0

9 to the 4th power. The bases are the same so you can leave them alone and simply subtract the powers, in this case it would be 12 minus 8, leaving you with 4, making the answer 9 to the 4th power.

What is the equation of the line? Use y = mx+b

Olegator [25]

Answer:

y = - $\frac{1}{2}$ x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 2) ← 2 points on the line

m = $\frac{2-3}{4-2}$ = - $\frac{1}{2}$

Note the line crosses the y- axis at (0, 4) ⇒ c = 4

y = - $\frac{1}{2}$ x + 4 ← equation of line
