Answer: -3

Concept:

Here, we need to understand the idea of evaluation.  

When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.

Solve:

<u>Given information</u>

x= -3

<u>Given expression</u>

5x - 4 [7 + (2x - 4)]

<u>Substitute x value into the expression</u>

=5(-3) - 4 [7 + (2(-3) - 4)]

<u>Simplify by multiplication</u>

=-15 - 4 [7 + (-6 - 4)]

<u>Simplify value in parentheses</u>

=-15 - 4 [7 + (-10)]

<u>Simplify value in bracket</u>

=-15 - 4 [-3]

<u>Simplify by multiplication</u>

=-15 - (-12)

=-15 + 12

=\boxed{-3}

Hope this helps!! :)

Please let me know if you have any questions

The function f(x) is given by the set of ordered pairs.
NISA [10]

The true equation will be f(6) = 0. Then the correct option is C.

<h3>What is a function?</h3>

A statement, principle, or policy that creates the link between two variables is known as a function.

The function f(x) is given by the set of ordered pairs.

{(1,0), (–10,2), (0,6), (3,17), (–2,–1)}

Then the function can be written as

f(abscissa) = ordinate

Then the function will be

f(0) = 6

Then the correct option is C.

The product of two numbers is 240. The first number is 8 less than the second number. Write an equation can be used to find x
DaniilM [7]

Answer:

The equation x = y-8

The equation  (y-8) y = 240

The first number x = 12 and second number y =20

Step-by-step explanation:

<u>Explanation</u>:-

<u>Step(l)</u>:-

Let 'x' be the first number and 'y' be the second number

Given the product of two numbers is 240

Given  data        x y = 240 …(l)

Given data the first number is 8 less than the second number.

                       x = y-8...(ll)

Substitute (ll) in equation (l) , we get

                           (y-8) y = 240

                           y^{2} -8y -240 =0

                            y^{2} -20y+12y -240 =0

                           y(y -20)+12(y -20) =0

                           (y +12)(y -20) =0

                          y = -12 and y = 20

              Y= -12 is not satisfied

              we can choose y = 20

<u>Step(ll):</u>-

Given data x =y-8

  substitute value y = 20 in x = y -8

                                             x = 20-8 = 12

<u>Final answer</u>:-

The first number x = 12 and second number y =20
