Answer:A
Step-by-step explanation:
The slope is -3 (You can do rise over run or (y2 - y1)/(x2 - x1)) and the y-intercept is 4,so the equation is y=-3x+4
Answer:
As a reduced fraction: minutes, which is 24 minutes
Step-by-step explanation:
Sam's speed is 1 lawn in 40 minutes. Vanessa's speed is 1 lawn in 60 minutes. If they both work together, the total speed is:
Which means that the total speed would be 5 lawns in 120 minutes. To find the time it would take to mow one lawn at that speed, we need to invert that speed so we get minutes per lawn:
Answer:
13,000
Step-by-step explanation:
250×52=13,000. I used a calculator
Cancel the (n+1) on the numerator and the (n+1) on the denominator
-----------------------------------------------------------------------------------------------------------
Change the divide fraction to a multiplication fraction
Take out common factors
The (10-x) from the numerator is cancel with (10-x) in the denominator
The 9 is also canceled
Combine the fractions
Simplify
The answer is 2 angle fgh because the outside angle is larger than 180 degrees
