What is the value of the function at x = 3?<br><br> Enter your answer in the box.
butalik [34]

Answer:

4

Step-by-step explanation:

Recall a linear function, is a line on a graph made up of an infinite amount of points which satisfy the relationship. That means at x=3 there is a specific point on the line with an output. The value of a function at x=3 asks, what is the output y value for the input x value?

To find it, we locate 3 on the x-axis. We draw a vertical line directly to the line following the grid line. We mark the point on the line. We then draw a horizontal line directly to the y-axis following the grid line. The point we hit on the y-axis is the value of the function.

Here it is 4.

-6(x+7)=-4x-2<br> How many solutions does it have
geniusboy [140]

Answer:

Equation have Unique solution i.e x=-20

Step-by-step explanation:

Given Equation:

-6(x+7)=-4x-2

Solving the Equation for 'x'.

           -6(x)-6(7)=-4x-2\\\\-6x-42=-4x-2

Adding '4x'  both sides:

             -6x+4x-42=-4x+4x-2\\\\-6x+4x-42=-2\\\\-2x-42=-2

Adding '42' both sides:

               -2x-42+42=-2+42\\\\-2x=40

                        x=\frac{40}{-2} \\\\x=-20

The equation have Unique solution with the value of x=-20
