Answer:
C. y = 2x -4
Step-by-step explanation:
We can use the points (0, -4) and (2, 0).
y = mx + b (m is slope, b is y-intercept)
m = delta y / delta x
m = 4 / 2
m = 2
y = 2x + b
We can plug in (2, 0):
0 = 4 + b
b = -4
y = 2x - 4
P(x) = √x
for x = 0 → √0 = 0 and p(0) = 0
for x = 1.44 → √1.44 =1.2 and p(1.44) = 1.2
for x = 2.25 → √2.25 = 1.5 and p(2.25) = 1.5
for x = 3.24 → √3.24 = 1.8 and p(3.24) = 1.8
for x = 4.41 → √4.41= 2.1 and p(4.41) = 2.1
for x = 5.29 → √5.29 = 2.3 and p(5.29) = 2.3
Here r ur terms : (9x^2) , (-5x) , (-7)......so there r 3 terms
constant : a number by itself...no variables....so ur constant is -7
Caroline's soccer practice starts at a quarter after 4 P.M. And ends at 5 P.M. How many minutes does her soccer practice last?
