C -3/2
Just multiply the second equation by -3/2
this will make the y term = -3/4y
so adding will eliminate the y terms.
Answer:
1.09
Step-by-step explanation:

The first thing you should do is calculate how many pounds of cheese a hamburger has
1 hamburger = 1/4 pound of cheese.
Then, you can make a rule of three to know how many pounds of cheese were sold:
1 ---> 1/4
310 ---> x
Clearing x we have:
x = ((310) / (1)) * (1/4) = 77.5
Answer
they sell last saturday 77.5 pounds of cheese
Answer:
58
Step-by-step explanation:
(2)(4) + (2)(-√-100) + (√-25)(4) + (√-25)(-√-100)
= 8 - 20i + 20i + 50 = 58
Answer:
Step-by-step explanation:
given is a differntial equation in parametric form as

We can find dy/dx by dividing y' by x'

(By separating the variables and integrating)
C is arbitrary constant
When x=-2, y =-2
Substitute to get

So solutoin is

is the solution
