A + b = 61 a > b a = 2b + 4
2b + 4 + b = 61
3b + 4 = 61
3b = 57
b = 19
Answer:
f(-x) is a reflection of f(x) in the y-axis
Step-by-step explanation:
–f (x) reflects the function in the x-axis (that is, upside-down). f (–x) reflects the function in the y-axis (that is, swapping the left and right sides).
trapezoid area = 1/2(a+b) h
area= 1/2 (120 + 145) 50
area = 25(265)
= 6,625 yards
For 11 on the dot plot its only supposed to be 2 dots because u only see two 11’s the mean is 78/15 which equals 5.2 the mode is 5 the range is 11-1 which equals 10
The sum will be:
sigma(i = 1 to infinity, 30*(2/5)^i)
->

Which is equal to 30/(3/5) = 50
