Answer:

x, xy, z

Step-by-step explanation:

In mathematics, a variable is a symbol or letter, such as "x" or "y," that represents a value. In algebraic equations, the value of one variable is often dependent on the value of another. For example, in the equation below, y is the "dependent variable" because its value is based on the value assigned to the "independent variable" x.

D Question 5 5. Given A is between Y and Z and YA = 14x, AZ = 10x and YZ = 12x + 48, find AZ<br>

Anna007 [38]

Answer:

Step-by-step explanation:

If A is in between Y and Z, then;

YA+AZ = YZ

Given.

YA = 14x,

AZ = 10x and

YZ = 12x + 48

Substitute into the formula

14x+10x = 12x+48

Find x;

24x = 12x+48

24x-12x = 48

12x = 48

x = 48/12

x = 4

Get AZ

AZ = 10x

AZ =10(4)

AZ = 40

Subtract 7x^2−5xy+8y^2 from −2x^2−15xy+9y^2

Ghella [55]

Answer:

$y^2-10xy-9x^2$

Step-by-step explanation:

We want to subtract $7x^2 -5xy+8y^2$ from $-2x^2-15xy+9y^2$ .

We set up the subtraction problem as follows:

$(-2x^2-15xy+9y^2)-(7x^2-5xy+8y^2)$ .

We expand the brackets to obtain;

$=-2x^2-15xy+9y^2-7x^2+5xy-8y^2$ .

We regroup the terms to obtain;

$=9y^2-8y^2-15xy+5xy-2x^2-7x^2$ .

We now simplify to obtain;

$=y^2-10xy-9x^2$ .
