Hi there! The first answer is correct.
You start with $5 and save $10 a week until you have at least $45. This situation is represented by the equation, because the variable 10w makes sense with this story and because we have a greater than or equal sign. This means that the left side of the inequality (the savings) must be greater than or equal to $45.
Answer:
d x / d y = -x2 - 2 y + 8 / 2 x y + 6
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
The first thing you would want to do is to draw it out. Once you've drawn it out, you want to add the "imaginary lines" so the trapezoid will form into a rectangle. Then find out the area which is L * W. The area for the rectangle is 20.
Finally you want to take those imaginary pieces and find the area of those. Which would be three and then you want multiply by two since there is two of them. The last thing you need to do is subtract the six from 20.
<u>Therefore the answer is 12.</u>
In y=kx , subst. -30 for x and 3 for y. Then solve the resulting equation for k:
3 = k(-30).
Dividing both sides by -30, we get:
-3/30 = -1/10 = k
The constant of proportionality is k = -1/10.
18/3(3)
18/9
2 would be your final answer
