Simplify the following:
8/(1/3)
Multiply the numerator of 8/(1/3) by the reciprocal of the denominator. 8/(1/3) = (8×3)/1:
8×3
8×3 = 24:
Answer: 24
Answer:
2
Step-by-step explanation:
The average rate of change from x=1 to x=2 is the same as finding the slope of a line at x=1 and x=2.
So we are going to need to corresponding y coordinates.
What y corresponds to x=1? y=3
What y corresponds to x=2? y=5
So we have the ordered pairs (1,3) and (2,5).
Line the points up vertically and subtract vertically then put 2nd difference over 1st difference.
(2 , 5)
-(1 , 3)
-----------
1 2
The average rate of change is 2/1 or just 2.
Now since we were asked to find the average rate of change given the function was a line, it really didn't matter what two points you used on that line.
Answer:
15 cm, 15 cm, 11 cm
Step-by-step explanation:
let the equal sides be x then the third side is x - 4
The perimeter is the sum of the 3 sides and is 41 cm , then
x + x + x - 4 = 41
3x - 4 = 41 ( add 4 to both sides )
3x = 45 ( divide both sides by 3 )
x = 15
x - 4 = 15 - 4 = 11
The sides are 15 cm, 15 cm, 11 cm
Find the slope soooo its (y2-y1/x2-x1)= -4/4 so -1 is slope
equation is y=-x+4
