Answer:
B
Step-by-step explanation:
IV does not represent y as the function of x since the ordinates share the same abscissa. As we can see in the graph {(4,-1),(4,4),(-4,-1),(-4,4)}

Answer:
D x = 18
Step-by-step explanation:
Given equation:
−2x = −36
Divide both sides by -2 to find x
−2x / -2 = −36 / -2
x = −36 / -2
x = 18
x = 18 makes the equation −2x = −36 true
Answer: <span>(x, y) → (x + 8, y – 3)
Justification:
</span>1) From the figure you can tell that the original trapezoid ABCD was translated 8 units to the right and 3 units down to yield the trapezoid A'B'C'D'.
2) Translating 8 units to the right means: x → x + 8
3) Translating 3 units down means y → y - 3
4) Therefore, the pair (x,y) is transformed into the pair (x + 8, y - 3); that is the rule (x,y) → (x + 8, y - 3)
Area of a triangle= 1/2 base times height
substitute
40=1/2*10*x
40=5x
x=8
the height is 8 inches
