Answer:
8
Step-by-step explanation:
Given,
f(x) = 8(x)
To value of a function at any point can be calculated by substituting that value in place of x.
Therefore,
f(1) = 8(1) = 8
f(2) = 8(2) = 16
The change over the interval from x=1 to x=2 can be calculated using 
=> 
=> 8

Answer:
I think there is an error in the question, I assume it reads:
4x+2y=20
x+3y=50
If not, please make appropriate corrections to the question.
Answer: x=-4, y=18
Step-by-step explanation:
4x+2y=20
Simplify, divide by two,
2x+y=10.....................(1)
x+3y=50....................(2)
Multiply (2) by 2
2x+6y=100 ....................(2a)
Subtract (1) from (2a)
2x+6y - (2x+y) = 100 - 10
5y = 90
y=18..............................(3)
Substitute (3) into (1)
2x+(18)=10
2x = 10-18 =-8
x=-4 ............................(4)
Substitute (3) and (4) into (1) for verification
2x+y = 2(-4)+18 = 18-10 = 10 checks.
Substitute (3) and (4) into (2) for verification
x+3y=-4+3(18) = -4+54 = 50 checks.
Have a nice day!
5 and 6 is 65 and 3 and 2 is 25 so I would say add 65 and 25
Answer:
Divide. Answer is 4
Step-by-step explanation:
First, divide.
Since you can't have a third of a box, you need the next number up, which is 4.
