Answer:
−18c+83d+4x+1077
Step-by-step explanation:
combine all like terms
(2x+2x=4x)
(5d+78d=83d)
(-9*2c=-18c)
(1077=844+233)
Answer:
2.56
Step-by-step explanation:
The equation they dive u: d = 16t^2, so in the question they said what's the distance, d, if t = 0.4
So you just have to replace t with 0.4:
d = 16t^2
d = 16(0.4)^2
d = 16(0.16)
d = 2.56
Please present the relationship in a table arranged vertically:
<span>this relationship. X= 0, 2, 4, 6, Y= 0, 8.4, 16.8, 25.2 becomes:
</span><span> x y
--- -----
0 0
2 8.4
4 16.8
6 25.2
Notice that as x increases by 2 units from 2 to 4, y increases by 8.4 units to 16.8. Thus, the slope of this line is
16.8
m = -------- = 8.4
4-2
Your problem statement sounds incomplete; what were you asked to do here?
You could compare the equations of the 2 functions:
y = 4.2x and
y = 8.4x
The slope of the 2nd function is twice that of the first function. Both graphs go through the origin, (0,0).</span>
