Mathematics
1 answer:
AnnZ [28]3 years ago
5 0

Answer:

y = 4x - 26

Step-by-step explanation:

The change in y is 4 when the change in x is 1.

So the slope is change in y/change in x = 4/1 = 4

y = mx + b

30 = 4(14) + b

30 = 56 + b

b = - 26

Therefore,  y = 4x - 26

Please Help Me!!!!! The displacement of a particle d (in km) as a function of time t (in hours) is given by: d(t) = 2t^3 + 5t^2
seraphim [82]

Answer:

Step-by-step explanation:

hello,

for t = 4 hours

d(4)=24^3+54^2-3=2*64+5*80-3=128+80-3=205

this is 205 km

d is differentiable and

d'(t)=6t^2+10t

and

d'(4)=6*4^2+10*4=6*16+40=96+40=136

this is 136 km/h

d' is differentiable and

d''(t)=12t+10

and

d''(4)=12*4+10=48+10=58

this is 58 \ km/h^2

Step-by-step explanation:o

x + y = 10........(1)

x - y = 14..........(2)

Adding (1) and (2)

2x = 24

x = 24/2

x = 12

And x + y = 10.......(1)

12 + y = 10

y = 10 - 12

y = -2

The number are 12 and -2
