Answer:
The equation is a function
Step-by-step explanation:
-3x + 8 = y
Reverse the function.
y = -3x + 8
Draw a graph of y vs x (below)
To determine if the relation is a function, we can use the vertical line test:
If a vertical line crosses the graph more than once in any location, the relation is not a function.
We see that at no place will a vertical line intersect the graph more than once.
The relation is a function.
Answer:
Step-by-step explanation:
x + x + 65 °+ 25° = 180° ( being sum of angles of triangle )
2x + 90° = 180°
2x = 90°
x = 45
now
<A = 45°
< B = x + 65° = 45 °+ 65 °= 110°
< C = 25°
Hope it helps :)

Answer:
Over 5 days, the pool loses 11
inches of water.
Step-by-step explanation:
Since the leaky pool is losing water at a rate of 2 inches of water each day, than we can find the amount of water the pool has lost over 5 days, by either adding 2 five times, or just multiplying 2 by 5:
2 x 
So, the total amount of water lost over 5 days is 11 inches.
