Answer
You can multiply the first equation by 4 and the second equation by 3.
You can multiply the first equation by 4/3.
You can multiply the first equation by 3.
Explanation
When solving a system of equations by elimination, you want to add or subtract the equations to "get rid" of a variable.
To do that, one of the variables in both equations have to have the same coefficient.
The first answer possible gives x the coefficient of 12 for both equations. You would get 12x+4y=52 and 12x-9y=39. You could subtract those equations to get 13y=13.
The second way gives x the coefficient of 4. You would multiply the first equation by 4/3 to get 4x+4/3y=52/3. You can subtract to get one variable, and then solve from there. Although, multiplying for 4/3 is annoying, so it's not suggested.
You can also "get rid" the the y. Multiply the first equation by 3 to get 9x+3y=39. You can add these equations. When you add 9x+3y=39 and 4x-3y=13 you get 13x=52.
Answer:
Both f(x) and g(x) have the same output value at x = 5
Step-by-step explanation:
When we are writing a function, while x gives the input value, writings like f(x), g(x) or h(x) will represent the output values of the input value of x
Now, looking at the relation, we are told that the value of f(x) = g(x) at x = 5
What this mean is that at x = 5; the output value of g(x) is the same as the output value of f(x)
Hence, we can conclude that both functions have the same output value at the given input value of x = 5
