75/15 is 5, so 15 would be 20%
because 15 is a fifth or 75
The function would be f (x) = 0.4x - 4.
Explanation
We can see that this is linear, since it increases at a constant rate. We find the slope using the formula
m=(y₂-y₁)/(x₂-x₁) = (0.8-0.4)/(12-11) = 0.4/1 = 0.4
We use point-slope form to write the initial equation:
y-y₁ = m(x-x₁)
y-0.4 = 0.4(x-11)
Using the distributive property:
y-0.4 = 0.4*x - 0.4*11
y-0.4 = 0.4x-4.4
Add 0.4 to both sides:
y-0.4+0.4 = 0.4x-4.4+0.4
y=0.4x-4
The answer is I don't know because if you add them both you get 5 and 6.
Answer:
The Answer is that one box of Oranges costs $7.13 and one box of Apples costs $12.99.
Step-by-step explanation:
Let o = oranges and a = apples
Equation 1:
3o + 14a = 203
Solve for o:
3o = 203 - 14a
o = 203/3 - 14/3a
o = 67.66 - 4.66a
Equation 2:
11o + 11a = 220
Substitute:
11(67.66 - 4.66a) + 11a = 220
744.26 - 51.26a + 11a = 220
-40.26a = 220 - 744.26
-40.36a = -524.26
a = -524.26/-40.36 = $12.99 for a box of Apples
Solve for oranges, o:
o = 67.66 - 4.66a
o = 67.66 - 4.66(12.99)
o = 67.66 - 60.53 = $7.13 for a box of Oranges
Hope this helps!! Have an Awesome day!!! :-)
