The difference between two numbers is 19. Half the larger number plus twice the smaller number is 12. What are the numbers?
This is the equation I came up with but I can't make it work.
x-y=19
1/2x+2y=12
Answer:
y= 7/5x or f(x)= 7/5x
Step-by-step explanation:
The x intercept is -5 which as a point is (-5,0)
The y intercept is 7 which as a point is (0,7)
- find slope
m=7/5
2. write equation
- (The equation can be written as either y equals or the function of x equals)
- y=7/5x
- f(x)=7/5x
I believe if I did the expression correctly, the solution is 1
Answer:25 /77
Step-by-step explanation:
77 x - 8 = 17
Collect like terms
77 x = 17 + 8
x= 25 /77
