Answer:
options 4 and 6 I believe
<span>6x – 7y = 16
2x + 7y = 24
This system is easily solvable by the elimination method as the y-terms are opposites of each other. You may add the two equations together and they will cancel out.
</span> 6x – 7y = 16
2x + 7y = 24
+___________
8x – 0 = 40
8x = 40
x = 5
Substitute 5 for x into either of the above equation and solve algebraically for y.
2x + 7y = 24
2(5) + 7y = 24
10 + 7y = 24
7y = 14
y = 2
Check work by plugging both x- and y-values into each original equation.
6x – 7y = 16 => 6(5) – 7(2) = 16 => 30 – 14 = 16
2x + 7y = 24 => 2(5) + 7(2) = 24 => 10 + 14 = 24
Answer:
x = 5; y = 2

-14,-8,-5,-4,-2,0,1,3,5,8,12
Step-by-step explanation:
the least is always in order from the greater negative number and to the greater positve number
Answer:
30
Step-by-step explanation:
Vcone=(1/3)hpir^2
d/2=r
18/2=d/2=9=r
h=18
v=(1/3)(18)(pi)(9^2)
V=(6)(pi)(81)
V=486pi
V=1526.04 ft³
