Answer:
8 ten dollar bills
20 fifty dollar bills
Step-by-step explanation:
x = number of 10 dollar bills
y = number of 50 dollar bills
x+y = 28
10x+50y = 1080
Multiply the first equation by -10
-10x -10y = -280
Add this to the second equation
-10x -10y = -280
10x+50y = 1080
-----------------------
40y = 800
Divide by 40
40y/40 = 800/40
y = 20
Now find x
x+y =28
x+20 = 28
x = 28-20
x= 8

Step-by-step explanation:
Answer:
1) y = tan(xlnx-x+tan⁻¹(3) + 1)
2)
Step-by-step explanation:
1) y' = ln(x)(1 + y²), y(1) = 3 Ans y= tan(x lnx-x+1+tan⁻¹(3))
solution:
y' = ln(x)(1 + y²)
using condition y(1) = 3
tan⁻¹(3)=-1+c
c = tan⁻¹(3) + 1
now,
tan⁻¹(y)=xlnx-x+tan⁻¹(3) + 1
y = tan(xlnx-x+tan⁻¹(3) + 1)
2) y' = 9x² √(1 + x)³ (1 + y²), y(0) = 3
let 1+x³=u
inserting value of 'u' in equation above
inserting value y(0) = 3
c = tan⁻¹(3) - 2
Answer:
a = 6
b = 3/4
Step-by-step explanation:
They both need to have the same slope.
The slope in the first equation is 6
That means that the second equation must have a = 6
They both need to have the same y intercept
The second equation has a y intercept of 3/4
Therefore b in the first equation, must be 3/4
