Step-by-step explanation:
-25 + 14 ÷ (5-3)
= -25 + 14 ÷ (2)
= - 25 + 7
= - 18
Answer:
d.) 81
Step-by-step explanation:
f(2) would be 27 and 27x3 is 81.
81/3=27
27/3=9
Add all the sides then divide by how many sides it is
Answer:
Option B
Step-by-step explanation:
Lets open the brackets of L.H.S.
Lets substract q² from both the sides.
Lets divide both the sides by q.
You can identify the lines and their colour either by
1. the y-intercepts.
First equation has a y-intercept of 3 and second has a y-intercept of 2.
So first equation is blue, and second is red.
2. the slopes
First equation has a negative slope (so blue), and second has a positive slope (so red).
Now work on each of the equations.
1. first equation (blue)
If we put x=0, we end up with the equation y≤3, the ≤ sign indicates that the region is BELOW the BLUE line.
2. second equation (red).
If we put x=0, we end up with the equation y>2, the > sign indicates that the region is ABOVE the RED line AND the red line should be dotted (full line if ≥).
So at the point, it won't be too hard to find the correct region.
To confirm, take a point definitely in the region, such as (-6,0) and substitute in each equation to make sure that both conditions are satisfied.
