The answer to what plus what equals 56 is 1+55.
Answer:
3 iii
Step-by-step explanation:
I hope this helps with your question :)
So you know:
1) There are 180° in a triangle.
2) A straight line is also 180°.
So the three angles in the triangle are
2x, 103-x, and (180-(6x-7)).
Solve for x!
2x + 103-x + (180-(6x-7)) = 180
2x + 103-x + 180-6x+7 = 180
-5x = -110
x = 22
Answer:
f(g(2)) = 51
Step-by-step explanation:
The expression f(g(2)) means you are to use g(2) as the argument for the function f(x).
__
The value of a function is found by substituting the argument value in the defining expression, then simplifying the result.
Here, we do that in steps, working outward from the innermost parentheses, as required by the Order of Operations.
g(2) = 7(2^2) = 7·4 = 28 . . . . . put 2 where x is in g(x) = 7x^2, evaluate
f(g(2)) = f(28) = 2(28) -5 = 56 -5 = 51 . . . . . . put 28 where x is in f(x) = 2x -5
f(g(2)) = 51

Many graphing calculators will let you define functions. You can use the calculator to compute the value for you. A spreadsheet can do the same thing.
