Which phrase matches the algebraic expression below?

3(x − 7) + 10

The required phrase is " three times the difference of x and seven plus ten

Step-by-step explanation:

The given algebraic expression is

We have to first subtract x from seven i.e. x-7 and then multiply this expression by 3 to get:

The expression is added by a constant 10 i.e. we get the final expression as:

Difference of x and seven = (x-7)

Three times difference of x and seven = 3(x-7)

Three times difference of x and seven plus ten = 3(x-7)+10.

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3
