Write the algebraic expression for: the sum of a number and 5 decreased by twice the number.
Vera_Pavlovna [14]

The algebraic expression for: the sum of a number and 5 decreased by twice the number is (n + 5) - 2n

<h3>Algebra</h3>

let

  • The unknown number = n

sum of a number and 5

= n + 5

decreased by twice the number

= -2(n)

= - 2n

sum of a number and 5 decreased by twice the number

= (n + 5) - 2n

= n + 5 - 2n

= 5 - n

Therefore, the algebraic expression which can be used to represent; the sum of a number and 5 decreased by twice the number is (n + 5) - 2n

The trick here is to substitute points given
f(x) = a \times {b}^{x}
substituting point A x-value =b
f(b) = a \times  {b}^{b}
turns out false since (b,a*b^b) !=(b,0)
substituting point B x-value=0
f(0) = a \times  {b}^{0}  = a
turns out true since (0,a)=(0,a)

we already got f(x) at x =0 which is not the point (0,0)
so c is false
substituting D x-value=a
f(a) = a \times  {b}^{a}

hence B is the correct answers
