Answer:
y = 
x + 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
here m = , hence
y = x + c ← is the partial equation
To find c substitute (- 10, 6) into the partial equation
6 = - 2 + c ⇒ c = 6 + 2 = 8
y = x + 8
Answer:
18
Step-by-step explanation:
it is 18 because you would 36 divided by 4 to get 9. Then you would do 9 plus 6 to get the answer 18
Answer:
x=4 and y=1
Step-by-step explanation:
Equation 1) 3x+8y=20
Equation 2) 5x+3y=23
Equation 1) 5(3x+8y=20 )
Equation 2) 3(5x+3y=23)
15x+40y=100
15x+9y=69
(Take away 40y from 9y and 100 from 69)
31y = 31
y=1
Substitute y=1 into equation 1)
3x+8=20
(Take away 8 from both sides)
3x=12
(Divide by 3)
x=4
We have the following limit:
(8n2 + 5n + 2) / (3 + 2n)
Evaluating for n = inf we have:
(8 (inf) 2 + 5 (inf) + 2) / (3 + 2 (inf))
(inf) / (inf)
We observe that we have an indetermination, which we must resolve.
Applying L'hopital we have:
(8n2 + 5n + 2) '/ (3 + 2n)'
(16n + 5) / (2)
Evaluating again for n = inf:
(16 (inf) + 5) / (2) = inf
Therefore, the limit tends to infinity.
Answer:
d.limit does not exist
Write it out as a set of equation:
Let x be number of 8 cent stamps, y be 10 cent stamps, and z be 2 cent stamps.
x=y
z=x+y
8x+10y+2z=440
Lets first solve for x:
from x=y and z=2x(from first equation) the last equation is
8x+10x+4x=440
22x=440
x=20
know that x=20, you also know that y=20 as well, since z=x+y, z=40.
So 20 8-cent stamps, 20 10-cent stamps, and 40 2-cent stamps.
