-3/2
slope = rise/run
We can use the two points to calculate rise (y value change) and run (x value change)
slope = (-6)/4 = -3/2
The other number could be 6. The GCF of 6 and 24 is 6, and 6 is less than 30.
Answer:
3.657 and 7.657 to the nearest thousandth.
Step-by-step explanation:
x - y = 4
x^2 + y^2 = 72
From equation 1
x = y + 4 so
(y + 4)^2 + y^2 = 72
y^2 + 8y + 16 + y^2 - 72 = 0
2y^2 + 8y - 56 = 0
y^2 + 4y - 28 = 0
y = 3.657.
so x = 7.657.
Answer:
$27.34
Step-by-step explanation:
250 miles divided by 32 miles per gallon equals 7.8125 which is the number of gallons needed. Then multiple 7.8125 by the cost per gallon $3.50 to determine the cost of the fuel needed.
