Answer:
B
Step-by-step explanation:
It has a slope of -1/4
and it's y intercept is 2
y = -1/4x + 2
Answer:
x=20
Explanation to Answer:
Use distributive property for the first step. Meaning you multiply the 0.1 by the x and 80. You will now get 0.1x+8+0.2x=14.
For the second step, collect like-terms. Add the 0.2x to the 0.1x and you should 0.3x+8=14.
For the third step, move the constant to the right. Subtract the 8 by itself and it will cancel out. Subtract the 14 by 8 and you will get 6. Your new equation should be 0.3x=6.
Divide both sides by 0.3. Just like in the third step with 8, 0.3 will cancel itself. When divide 6 by 0.3, you will get your answer, x=20.
You're welcome, and I hope this helps!
Answer:
10x
Step-by-step explanation:
By definition
So we just need to multiply the two functions
Step-by-step explanation:
You can solve this by splitting it into a net and calculating the areas of each shape
Count the triangles: 4
rectangles: 1
area of a triangle: 0.5 x b x h
area of a square : L x W
4(0.5 x b x h) + L x W = surface area
