D because each y value is obtained by multiplying x by -2
y = -2x which is direct variation.
To solve this problem you must apply the proccedure shown below:
1. You have that:
-The length is
feet.
- The width is
feet.
- The height is
feet.
2. The box has one base. The cost of the base is:
![c1=4.20xy](https://tex.z-dn.net/?f=%20c1%3D4.20xy%20)
3. It has four sides. The cost of the sides are:
![c2=2(0.75yz)+2(0.75xy)\\ c2=1.5yz+1.5xy](https://tex.z-dn.net/?f=%20c2%3D2%280.75yz%29%2B2%280.75xy%29%5C%5C%20c2%3D1.5yz%2B1.5xy%20)
The answer is: The total cost is ![c=c1+c2\\ c=4.20xy+1.5yz+1.5xy](https://tex.z-dn.net/?f=%20c%3Dc1%2Bc2%5C%5C%20c%3D4.20xy%2B1.5yz%2B1.5xy%20)
Hello!
So let's first start out by solving the left side of the equation:
2 to the third power is 8
The right side now: -3 to the second power is -9
In total: 8- (-9)
So your answer is C) -1
I hope it helps!
Answer:
5 eggs.
Step-by-step explanation:
Well, 3/4 of 12 is 9 and 5/6 of 12 is 10. So, 12 - 9 = 3 and 12 - 10 = 2
Therefore, Matthew has 5 eggs left over.
I hope I helped ^^
Answer:
m∠A = 59°
Step-by-step explanation:
Supplementary angles mean that, when the two are combined, their total measurement will equal 180°.
It is given that one of the angles is 121°. Subtract 121 from 180:
180 - 121 = 59
m∠A = 59°
