Answer:
67
Step-by-step explanation:
We are given the expression:
and asked to evaluate when w=9, x=7, and y=1.
The expression does not contain the variable y, so we can disregard it.
However, the expression does have the variable x and w. We can substitute 9 in for w and 7 in for x.
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
First, multiply 9 and 7.
9*7=63
Next, add 63 and 4.
The expression wx+4 when evaluated for w=9 and x=7 is equal to 67.
