Answer:
32 units squared
Step-by-step explanation:
Split up the figure into easy to find area parts. So, theres 2 triangles, and in the middle of those, you can make a square. And that would make the top part a large triangle! Now find the area of these
Large triangle: 1/2 (4)(10) = 20
Smallest triangle: 1/2(2)(2) = 2
Medium triangle: 1/2(6)(2) = 6
Square: 2*2 = 4
Now add them all up! 20+2+6+4 = 32 units squared!
Answer:
x = -4, -2
Step-by-step explanation:
<u>Key skills needed: Quadratics, Factoring, Solving for Roots</u>
1) We are given : and we need to solve for the roots.
2) You have to factor.
You need to find what factors of 8 add up to 6.
The factors of 8 are --> 1,2,4,8
The 2 factors that add up to 6 and multiply to equal 8 are --> 2 & 4
3) This means it would become ---> .
4) Set x + 4 = 0 and get x = -4 as one root
Set x + 2 = 0 and get x = -2 as another root.
The 2 roots are -4, and -2

Answer:
The exact charge per cubic foot of water usage is 4 Cents.
Step-by-step explanation:
Let the per cubic foot charge be $ 'x' and the fixed charge be $ 'y'.
A household using 1100 cubic feet was billed $ 114.
Therefore, we get the equation,
.......( A )
And other household 1500 cubic feet was billed $ 130.
Therefore, we get the equation,
......( B ).
Now, we subtract equation A from equation B.
.....( B )
......( A )
__________________
So, we get,
.
Therefore,
Cents.
So, the exact charge per cubic foot is 4 Cents.
Answer:
Step-by-step explanation:
We can denote this increase with the function , where is value after years.
Substituting , we get:
I think that the slope is 3/7
