Answer:
Step-by-step explanation:
Putting value of z = 3
6(3)2+ 2(3) + 10
6(9) + 6 + 10
54 + 16
70
Answer:
5
Step-by-step explanation:
5 time 5 is 25
25 time 5 is 125
Range is the y-values and since the arrows extend off the graph, we can assume it goes on forever so
answer: (-infinity,+infinity)
make sure it’s parenthesis, not brackets
Answer:
27.5 (is greater than) -2.5
>
Step-by-step explanation:
Distribute 5/3 to 6x and 9, (5/3•6x)+(5/3•9)=10x+15.
Set 10x+15 equal to 2x-5
10x+15=2x-5
(get rid of the smaller slope)
-2x -2x
8x+15=-5
+15 +15
8x=10
(divide by 8 to get the value of x)
8x divided by 8=x
10 divided by 8=1.25
x=1.25
Plug the known value of x back into the equations.
10(1.25)+15=27.5
2(1.25)-5=-2.5
27.5 (less than or equal to) -2.5 is incorrect. It would be
27.5 (is greater than) -2.5
