SCORPION-xisa [38]3 years ago
4 0

Answer:

5' 10"

Step-by-step explanation:

We subtract by converting into one measurement. We will choose inches.

8'4"= 96"+4"=100" since 8' has 8(12) inches

2'6"=24+6=30" since 2' has 2(12) inches

Subtract.

100"-30"=70"

We convert back into feet and inches by dividing by 12.

70/12= 5' 10"

⦁ Determine if the equation represents a direct variation. .8x = 1.6y ⦁ Suppose y varies directly with x. Write a direction vari
Mkey [24]
Part A:

Given that 

0.8x=1.6y\Rightarrow x= \frac{1.6}{0.8} y=2y

Thus, x = ky where k = 2.

Therefore, the given equation is a direct variation.


Part B:

If y varies directly as x, then y = kx.

Given that y = 5 when x = 2, then

5=2k \\  \\ \Rightarrow k=\frac{5}{2} =2.5 \\  \\ \Rightarrow y=2.5x

When x = 12, y = 2.5(12) = 30.



Part C:

If y varies directly as x, then y = kx.

Given that y = 9 when x = -6, then

9=-6k \\ \\ \Rightarrow k=-\frac{9}{6} =-\frac{3}{2} \\ \\ \Rightarrow y=-\frac{3}{2}x

It can be seen that the equation above satisfies all the rows of the given table, therefore, y varies with x for the data in the question and the equation for the direct variation is y=-\frac{3}{2}x



Part 4:

If y varies directly as x, then y = kx.

Given that y = 1 when x = -2, then

1=-2k \\ \\ \Rightarrow k=-\frac{1}{2} \\ \\ \Rightarrow y=-\frac{1}{2}x

It can be seen that the equation above does not satisfies the other rows of the given table, therefore, y does not vary with x for the data in the question.
