There are three steps
1 rearrange the equation so "y" is on the left and everything else is on the right
2 plot the "y=" line (make it a solid line for y< or y> and a dashed line for y< or y>)
3 shade above the line for a "greater than" (y> or y>) line under that or below the line for a less than (y< or y< line under it)
Answer:
One number is 4.2, the other is 18.8
Step-by-step explanation:
1.) x+y=23
(x+6y)x2=4
2.) (x+6y)x2=4 = 2x+12y=4
3.)Use elimination/substitution to solve
2x+12y=4 = x+6y=2 = x=2-6y
2-6y+y=23
4.)Solve for y
2-5y=23 -> -5y=21 -> y=4.2.
5.)Solve for x
x+4.2=23
x=18.8
I may be wrong so let me know if I am
The answer is D.9 , you just have to do an average wich is (12+6)÷2 and there you have it
Answer:
f(5)=70
Step-by-step explanation:
what f(5) means is put 5 in for x
so, 3(5)^2-5
3(5*5)-5
3(25)-5
75-5
70
