Remark
Watch out for the -4<=x<=6 thing. It causes lot's of problems if you are not careful.
Solution.
The second best answer is A and if that restriction, -4<=x<=6, wasn't there, the answer would be A.
When y = - 4, the x value falls outside the restricted domain ( -4<=x<=6) we have been given. so B is not the answer.
When x = - 4 you have to read straight down to see what the y value is. It is - 2. So this is your answer. Only exactly what is the answer. They ask for the minimum value and that is a y value in this case.
So the answer is C <<<<< Answer.
When y = 1 , x = - 2 1/2. That is within the domain, but it is not the minimum value so D is wrong.
Answer:
x=5, y=10. (5, 10).
Step-by-step explanation:
12x+6y=120
4x+y=30
-------------
2x+y=20
4x+y=30
----------------
y=20-2x
4x+(20-2x)=30
4x+20-2x-30
2x-30-20
2x=10
x=10/2
x=5
4(5)+y=30
20+y=30
y=30-20
y=10
-3x+5y=10 (add 3x on both side)
5y=3x+10 ( divide 5 to each term)
y=3/5x+2
slope is 3/5
y-intercept is 2
Answer:
Step-by-step explanation:
V = l * h * w
You know the volume (570), the width (6), and height (5). Plug it in and you get 570 = 6 * 5 * l. You can further simplify and get 570 = 30l. To undo multiplication, you must divide. 570/30 = 19.
