Step-by-step explanation:
the calculation is included. I hope its self explanatory
Answer:
the graph on the right-top
Step-by-step explanation:
Transferring an "x" to the right side in
, we get 
The system of inequalities is

We have y=2x+2 - ascending function with a=2, b=2
b=2 shows that ascending function intersects Y-axis is in y=2 - that situation is only on the right-top and left-down. So, we refuse left-top and right-down.
y=-x-3 - descending function with a=-1, b=-3
y<2x+2 is an area below the ascending function and we see that on the left-
is an area above the descending function
On the left-down we have an area above both functions, so we refuse this picture
Right-top is correct
Answer:
b.
Step-by-step explanation:
The given function is

Recall that the reciprocal of the cosine ratio is the secant ratio.
This implies that;



We take the inverse cosine of both sides to obtain;

0.50x + 8.75 < = 16
0.50x < = 16 - 8.75
0.50x < = 7.25
x < = 7.25 / 0.50
x < = 14.5 <===
