Answer:
When x = 12, y = 4, and z = 2, 8x + 2yz = 112.
Step-by-step explanation:
8x + 2yz
Substitute variables given:
x = 12
y = 4
z = 2
8(12) + 2(4)(2)
Multiply 8 and 12.
96 + 2(4)(2)
Multiply 2 and 4.
96 + 8(2)
Multiply 8 and 2.
96 + 16
Add 96 and 16.
112.
In order to find the answer to this question, you would need to find the Greatest Common Factor of 16 and 12 which would be 4 because 4 is the greatest amount that you can divide both 12 and 16 by. So the soonest both ships will leave together again will be in 4 days.
The variables x and y vary inversely. When y is 5 x is 3, so when y is 15 x is 9.
The slope is 3 and the y-intercept is (0, 9.4)
