60 + 4*60= full price
$300=full price
I got 4*60 in the equation because 80% is 4 time 20%
The full price of the lawn mower is $300
Answer:
y = -3x + 2
Step-by-step explanation:
First, find the slope using rise over run (y2 - y1) / (x2 - x1)
Plug in the points:
(-7 + 4) / (3 - 2)
-3/1
= -3
Then, plug the slope and a point into y = mx + b to find b:
y = mx + b
-4 = -3(2) + b
-4 = -6 + b
2 = b
Then, plug b and the slope into the equation:
y = -3x + 2 is the equation
Answer:
(a/b)^k=a^k/b^k
Step-by-step explanation:
Using the laws of exponents, we know that (a/b)^k=a^k/b^k.
I couldn't get it to format correctly so just know that the "/" are for the fraction signs and the "^" is for the exponent marking.
