Answer:
2.5
Step-by-step explanation:
2.5(4k+2) =12k
2.5*6k=12k
{ 3 x - 2 y = 30 * ( 2 )
2 x + 3y = - 19 * ( -3 )
↓
6 x - 4 y = 60
- 6x - 9 y = 57
______________
-13 y = 117
y = 117 / - 13
y = - 9
For x :
3 x - 2y = 30
3 x - 2 ( -9) = 30
3 x + 18 = 30
3 x = 30 - 18
3 x = 12
x = 12 / 3
x = 4
x = 4 and y = -9
hope this helps!
6. x=9
7. x=-36
8. x=-5
9. -8
----
1. x less than or equal to -36
#2lazy2dotherest you gave a ton if you just make us do it you will never learn how to do it. Or next time just give us more points then we can do all. but otherwise, peace
Answer:
x=-10
Step-by-step explanation:
2x-8=4x+12
-2x. - 2x
-8=2x+12
-12. - 12
-20 = 2x
-10=x
The two graphs in the second picture are the graphs of exponential functions. You can detect it from the L shaped graphs.
The very first graph represents a linear function. A straight line always represents a linear function. In a Linear function, the change in the values of y is constant throughout in relative to change in x values.
The final graph represents a quadratic function rising on both ends.
Therefore, option b and c are the correct answers
