Answer:
2a + 3b = 5
b = a - 5
Step-by-step explanation:
2a + 3b = 5
b = a - 5
You can write this another way:
2a + 3(a-5) = 5 ( I added the second formula in the first one )
Now you gotta factor out:
2a + 3a - 15 = 5
Here im gonna do plus 15
2a + 3a = 20 ==> 5a = 20
Now if you divide by 5, you get: a = 4
Now you can fill in the second formula again
b = a - 5 (ill fill this in now)
b = 4 - 5 = -1
So, this makes:
a = 4 , b = -1
Answer:
solution:
x = pounds of cashews = 20
y = pounds of peanuts = 70
Step-by-step explanation:
x = pounds of cashews
y = pounds of peanuts

4.75x + 2.50y = 3.00*90
x + y = 90
---
put the system of linear equations into standard form
---
4.75x + 2.50y = 270
x + y = 90

Answer:
Step-by-step explanation:
Hello, first, let's use the product rule.
Derivative of uv is u'v + u v', so it gives:
Now, we distribute the expression of f(x) and find the derivative afterwards.
