Answer:
4m^(4)−3m^(3)−6m^(2)+5m
Step-by-step explanation:
Answer:
x=−2+3√2
Step-by-step explanation:
x2+4x+4−18=18−18
x2+4x−14=0
For this equation: a=1, b=4, c=-14
1x2+4x+−14=0
x=
−b±√b2−4ac
2a
x=
−(4)±√(4)2−4(1)(−14)
2(1)
x=
−4±√72
2
x=−2+3√2 or x=−2−3√2
Answer:
100 students on each bus
Step-by-step explanation:
100*4 is 400 so there might be just 4
Answer:
$420
Step-by-step explanation:
(100 - 40)x = 60x
60x - 20 = 40x
0.4x = $168
x = $168/0.4 = $420
Use slope intercept form for equation, which is y = mx +b. m is slope and b is the y-intercept.
Find slope by change in y over change in x. So pick two points, for example (0, 24) and (2, 20). Slope (m) will be
(y2-y1)/(x2-x1)
= (24-20)/(0-2)
= 4/-2
m = -2
Y-intercept is 24.
Equation is y = -2x + 24
