What is the coefficient of x in the following expression?

1 - 10x + 4y
Evaluate the following expression for x = 15.

LaTeX: \frac{1}{5}1 5x - 12

(1) The coefficient of x in this expression is -10.

(2) The value of the expression for x = 15 is -9.

Step-by-step explanation:

(1)

A coefficient is a numerical value that is placed before a variable or is multiplied by the variable in an algebraic equation.

For example, in the algebraic equation 4x² + 5y the coefficient of variable y is 5.

The expression given is:

1 - 10 x + 4 y

The coefficient of x in this expression is -10.

(2)

The expression provided is:

Compute the value of the expression for x = 15 as follows:

Thus, the value of the expression for x = 15 is -9.

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
