Answer:
Last option, a translation of 1.5 units left, 0.5 unit up, then a reflection across the x-axis
Step-by-step explanation:
Let's pick any random point. So let's just chose point L. Comparing point L to point L', we can already see that the options given are incorrect. For example, the first option with just translations is incorrect because when we do translate point L 1.5 units left and then 1.5 units down, it does not line up with point L'. For the second and third options, we know that L(-2.5, 1.5) and L'(-4,-2). Therefore, there must be some sort of shift left, right, up, or down, to go from coordinates with decimals to coordinates with whole numbers, leaving the last option, D, as the correct one.
If B is between A and C, and AB=3x+1, BC=2x-7, and AC=24, then find the value of x and the value of AB
let assume AC is straight line and B is on line
AB + BC = AC
3x+1 +2x -7 = 24
5x -6 = 24
5x = 30
x = 6
Simplify by opening the bracket;
x(x^2+6y^2)
=
Volume=areabase times height
base=traignele
area=1/2 times base times height=1/2 times 10 times 12=60
height=20
volume=60 times 20=1200 cubic feet
2nd option
