Answer:
k=7,y=2.33 and y=k/x^2
Step-by-step explanation:
y=k/x^2
7=k/1
k=7
y=k/x^2
y=7/3
y=2.33

Answer:
A + B = 24
16A + 20B = 434
Step-by-step explanation:
To write a system of equations for this scenario, let's say that A represents the number of hours machine A ran, and B represents the number of hours machine B ran.
The first equation will be:
A + B = 24
because the total number of hours ran is 24.
The second equation will be:
16A + 20B = 434
because the total number of items made is 434.
A + B = 24
16A + 20B = 434
First solve for one variable, and let's just do A.
Using the first equation, A + B = 24, A is equal to 24 - B.
Substitute this value to the second equation.
16 (24 - B) + 20B = 434
384 - 16B + 20B = 434
4B = 50
B = 12.5
Now use this value of B to find the value of A.
A + 12.5 = 24
A = 11.5
Machine A ran for 11.5 hours, and Machine B ran for 12 hours.
Answer:
do you need an equation for this because if so it is
y - 2 = 7 (x - 4)
Step-by-step explanation:
you just use y - y = m (x - x)
Answer: There are 60060 ways to do so.
Step-by-step explanation:
Since we have given that
Number of linden trees = 6
Number of white birch trees = 4
Number of bald cypress trees = 3
Total number of trees = 6 +4 +3 =13
So, Number of ways that the landscaper plant that trees are evenly spaced is given by
Hence, there are 60060 ways to do so.
Let, the Age of Michelle = x
Age of Steve = x + 15
After 8 years, (x + 15 + 8) = 2(x + 8)
x + 23 = 2x + 16
2x - x = 23 - 16
x = 7
So, x + 15 = 22
In short, Age of Michelle is 7 & Age of Steve is 22 Years
Hope this helps!
