the zeros and the x-intercepts are the same with different names
x -intercepts are (- 7, 0 ) and (2, 0 )
if x = a is a zero then (x - a ) is a factor
thus (x + 7 ) and (x - 2 ) are the factors
Answer:
46
Step-by-step explanation:
By arranging the numbers from least to greatest, you can find the median by locating the central number in the data set.
a)
(59, 76) and (65, 100)
y - y1 = m(x - x1)
y - 100 = (100-76)/(65 - 59)(x - 65)
y - 100 = (24/6)(x - 65)
y - 100 = 4(x - 65)
y - 100 = 4x - 260
y = 4x - 160
b)
x = 90
y = 4x - 160
y = 4(90) - 160
y = 360 - 160
y = 200
200 chirps per minute
c)
y = 120
y = 4x - 160
120 = 4x - 160
280 = 4x
x = 70
70 degrees
