y2 - y1

x2 - x1
3 - 1 2 1
------- = -------- = --------
4 - 0 4 2
Find the y-intercept:
1 = 1/2(0) + b
1 = 0 + b
-0 -0
1 = b
The slope-intercept equation is:
y = 1/2x + 1
so its D
Answer:
Its 4/5
Step-by-step explanation:
you divisde 3/5 into the 5th. HOPE THAT HELPED!
2.)
average velocity=(change in distance)/(change in time), in this case:
v=(549 9/10)/(7 50/60)
v=(5499/10)/(470/60)
v=(5499/10)(60/470)
v=32994/470
v=70.2 km/hr

Make two position functions...
c=15t, and r=120-20(t-1)
c=15t, r=140-20t
They meet when c=r so:
15t=140-20t add 20t to both sides
35t=140 divide both sides by 35
t=4
So they will meet 4 hours after Cindy leaves at 1 pm, thus they meet each other at 5 pm.
check...
c=15(4)=60
r=120-20(4-1)
r=120-20(3)
r=60
Answer:
80 cars will maximize revenue
Step-by-step explanation:
The revenue per square meter for parked cars is ...
$2.00/5 = $0.40
The revenue per square meter for buses is ...
$6.00/32 = $0.1875
Thus the available space should be used to park the maximum number of cars.
80 cars should be in the lot to maximize income.
Answer:
(gxf)(1) = - 12
Step-by-step explanation:
Let f(x) = -4x + 7 and g(x) = 2x - 6.
(gxf)(1) = g(1)xf(1)
but : f(1) = -4(1)+7 =7-4 = 3 and g(1)=2(1)-6 =2-6 = -4
so : (gxf)(1) = g(1)xf(1) = (-4)(3)=-12
