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
5x + 3 ≥ 10
3 is adding on the left, then it will subtract on the right
5x ≥ 10 -3
5x ≥ 7
5 is multiplying on the left, then it will divide on the right
x ≥ 7/5
x ≥ 1.4
Then, the smallest integer value of x is 2
f(x)=40
x=8
so if x=2 it would be 40/8 which is 5
12 tens as in 12 10's
that equals
10+10+10+10+10+10+10+10+10+10+10+10
or 12 times 10
when multiply by 10, just move decimal place on e to the right
12.0 times 10=120
the answe ris 120
