You have not provided the complete question (value of y at a certain value of x), therefore, I cannot give u a specific final answer. However, I can explain how to solve this problem and you can apply on the numbers you have.
y varies directly with x means that as x increases, y also increases and vice versa.
This can be represented by the following equation:
y = kx
where k is the constant of proportionality.
Solving this for k, we would find that:
k = y/x
Examples:
If we are given that y = 4 at x = 2, then:
k = y/x = 4/2 = 2
If we are given that y = 1 at x = 3, then:
k = y/x = 1/3
In general, if we are given that y = a at x = b, then:
k = a/b

D= difference in height
A= Alex's height (1.6m) N= Noah's height (1.5A)
Step 1:
D=N-A
substitute N= 1.5 A in for N
D= 1.5(1.6) - 1.6
D= 2.4 - 1.6
D= 0.8 m difference in height
Step 2:
Convert meters to centimeters 1 m = 100 centimeters
0.8 x 100-80cm
Noah is 80cm taller than Alex.
Hope this helps! :)
$15.41
Multiply the $1.79 by 4 which gets you $7.16. Then, add the $7.16 to the $8.25 and that gets you $15.41.
Answer:
The slope is -5
Step-by-step explanation:
<u>Slope is the number attached to the x</u>
For this problem, y = -2/3 - 5x, the slope/number attached to the x is -5. So, the slope is -5.
Answer: The slope is -5
If you want to make 10, you can take 3 from the 13 and add it to the 7. You will then have 10+10 which equals 20.
