1/4 of x students made the honor roll in the first quarter
1/4 of x plus 18 equals 105
1/4 x + 18 = 105
1/4 x + 18 - 18 = 105 - 18
1/4 x = 87
Reciprocal to isolate variable
4/1(1/4 x) = 87(4/1)
x = 348
There is a total of 348 students in 7th grade
All real numbers, domain of definition is from -infinity till + infinity
Since the total is 42 divide by two since they are the same length so it would be 21
Answer:
Average rate of change = 3
Step-by-step explanation:
- We know that the average rate of change is basically a measure of the slope of the secant line in the closed interval [a, b].
here a = -3 and b = 4
⇒ Average rate of change = f(b) - f(a) / b - a
= (27 - 6) / (4 - (-3))
= 21 / 7
= 3
Therefore, Average rate of change = 3
1. (70 - 44) / 2
2. (45.00 - 25.50) / 6
3. (75 - 39) / 3
4. (90 - 30 +10) / 3
5. (100- 30+10) / 10
6. (50 - 5) / 10
PS: / means divide or division. also remember PEMDAS
Hope this helped you (;
