Answer:
(x, y) = (5, 3)
Step-by-step explanation:
We can use the second equation to substitute for y in the first.
x = 17 -4(x -2)
5x = 25 . . . . . . . . eliminate parentheses, add 4x
x = 5
y = 5 -2 = 3
The solution is (x, y) = (5, 3).
2/3 is not equivalent to 1/3
2/6 is equivalent to 1/3
Answer: 17
Step-by-step explanation:
Answer:
B. f(g(x)) = -10x + 8
Step-by-step explanation:
When evaluating f(g(x)), substitute what g(x) is in place of g(x).
So instead of
f(g(x))
the function would be:
f(-5x + 6).
Now all you have to do is evaluate this.
To evaluate this function, substitute the value inside the f(x) for all instances of x in the equation.
f(x) = 2x - 4
f(-5x + 6) = 2(-5x + 6) - 4
f(-5x + 6) = -10x + 12 - 4
f(-5x + 6) = -10x + 8
Therefore, f(g(x)) = -10x + 8.
Answer:
y= -x-8
Step-by-step explanation:
y=mx+b
-3= -1(-5)+b
-3=5+b
-8=b
