Step-by-step explanation:
What is the solution to this equation?
(1/4)^x+1 =32
A.) -2
B.)7/-2
C.)2
D.) 3/2
The slope of the line that best models the situation is the rate of change in the level of the pool. From the given problem, the rate of change is 0.5 / day. Thus, the slope is 0.5. The answer to this item is letter B.
Quadrilateral. If you add the angles up on any quadrilateral, it equals 360 (it should always add to 360 for a quadrilateral)
Because the left side is eclipsed in an absolute value, we have two possible values of x, denoted by:
2x+4 = 12 and -(2x+4) = 12
Solving for both of these, we are presented with the two values of x:
x = 4 and x = -8
A should be the right answer because 4*5/4=5 + 5*2=10 and 5+10=15.
