Answer:
A.
Step-by-step explanation:
The graph of the y-axis would be x=0
Take two points from both functions. You
will find out that both slopes are the same.
Also you can see that the functions have different y-intercepts.
If the functions have the same slope but different y-intercepts they are parallel to each other
I hope this helps
We know that
<span>total surface area of the composite solid=surface area of the pyramid+surface area of the cube
surface area of the pyramid=4*area of lateral triangle side
area of lateral triangle side=12*9/2----> 54 in</span>²
surface area of the pyramid=4*54---> 216 in²
surface area of the cube=5*[12*12]----> 720 in²
total surface area of the composite solid=216 in²+720 in²---> 936 in²
the answer is the option
<span>936 square inches </span>
12 - 7 is 5. you can count down 7 times from 12 like: 12, 11, 10, 9, 8, 7, 6, 5.

Answer:
8) 42 in²
9) 33 cm²
10) 112 yd²
Step-by-step explanation:
8) The area is given by the formula ...
A = 1/2(b1 +b2)h
A = (1/2)(9 in +5 in)(6 in) = 42 in²
__
9) The area is half the product of the lengths of the diagonals.*
A = 1/2(d1)(d2)
A = 1/2(6 cm)(11 cm) = 33 cm²
__
10) As in the previous problem, ...
A = 1/2(14 yd)(16 yd) = 112 yd²
_____
* This formula works for any quadrilateral with perpendicular diagonals.
