Answer:
x=-1, y=-5 ---> (-1, -5)
Step-by-step explanation:
so you want to plug one equation into the other. so start off by plugging y=−4x−9 into the y value of 4x−y=1-----> 4x-(-4x-9)=1. now subtract and isolate x which ends up being x=-1. now plug the x=-1 into either equation and isolate and solve for your y value which ends up being y=-5. you can check you answer by plugging both the x and y you found into one equation and making sure the answer it gives is true. ;)
7 is the absolute value for positive and negative 7, because they are 7 spaces away from the 0 on the number line.
Hope it helps.
Answer: 1350
Step-by-step explanation:
So 1.5 x 900= 1350
Answer:
12 y
Step-by-step explanation:
π. x².y = ⅓. π (½x) ².h
=> eliminate π,
x²y = ⅓. ¼x².h
=> eliminate x²,
y = 1/12 h
h = 12 y
so, height of the cone = 12 y
