C: y= 6
Since they are varying inversely, as one gets larger the other gets smaller and vice-versa.
Since when y=3 when x=4.....
When x gets divided by two y would get multiplied by two instead
So y=6 when x=2
4 yards by 7 yards. 2 multiplied by 14 is 28, and 4 multiplied by 7 is also 28.
Answer: 6 sticks

Given
Joe needs 
butter for each cake
One stick of butter is equivalent to 0.5 cup
So, joe need
for each cake
To bake 8 cakes, it is
Answer:
Step-by-step explanation:
xy = 42
x+y = - 2 Substitute into the top equation
y = -2 - x Put in for y
x(-2 - x) = 42 Remove the brackets
-2x - x^2 = 42 Subtract 42 from both sides.
-2x - x^2 - 42 = 0 Put in the more normal order.
-x^2 - 2x - 42 = 0 Multiply by -1
x^2 + 2x + 42 = 0
This cannot be factored. It gives complex roots as it is written. I will give you the answer but I kind of doubt the question is correct.
x1 = - 1 + 6.40i
x2 = -1 - 6.40i
Leave a comment if you have a correction.
Answer:
Move all terms to the left side and set equal to zero. Then set each factor equal to zero.
Exact Form:
x=1+√5 ,1−√5
