Answer:

The correct answer is option C.

Step-by-step explanation:

(3x^2 + 3x + 5) + (7x^2 - 9x + 8) = 10x^2 - 12x + 13

3x^2 + 3x + 5 + 7x^2 - 9x + 8= 10x^2 - 12x + 13

x^2(3+7)+x(3-9)+5+8= 10x^2 - 12x + 13

10x^2-6x-13=10x^2 - 12x + 13 (wrong)

10x^2-6x-13\neq 10x^2 - 12x + 13

Error made by Lucia was that she added coefficient of x. She must be subtracting those coefficients.

Hence,the correct answer is option C.

Step-by-step explanation:

349 ---100%

x ------ 20%

x= (349×20)÷100

x=69.8

349-69.8=279.2

279.2 ---100%

x-----7%

x=(279.2×7)÷100

For the function f(x) = -4x - 5, what are the outputs for the inputs -4, 1, 3, and 11?
Anika [276]

We have to find the output values for the given input values of the function given as,

  • f(x) = -4x - 5

Here, x = Input value of the function

And f(x) = Output values

By substituting the input values of x as,

For x = -4,

f(-4) = -4(-4) - 5

      = 16 - 5

      = 11

For x = 1,

f(1) = -4(1) - 5

    = -4 - 5

    = -9

For x = 3,

f(4) = -4(3) - 5

     = -17

For x = 11,

f(11) = -4(11) - 5

     = -44 - 5

     = -49

       Therefore, Option (A) will represent the output values for the given input values.
