Marrrta [24]

The value of the highlighted variables ave been determined a =6, b= 2 ,c= 6 , d = 2 , e = 6 , f = 6, g =1

<h3>What is an Expression ?</h3>

An expression are mathematical statement consisting of variables , constants and mathematical operators .

The given expression is

$\rm \dfrac{2}{x^2-36} - \dfrac{1}{x^2 +6x} = \dfrac{2}{(x+6)(x-6)}-\dfrac{1}{x(x+a)}\\\\= \dfrac{bx}{x(x+6)(x-6)}-\dfrac{x-c}{(x+6)(x+6)x}\\\\= \dfrac{dx-x+e}{x(x+6)(x-6)}\\\\= \dfrac{x+f}{x(x+6)(x-6)}\\\\= \dfrac{g}{x(x-6)}$

a = 6

b= 2

c= 6

d = 2

e = 6

f = 6

g =1

Therefore the value of the highlighted variables ave been determined.

The ratio of girls to boys in a particular classroom is 8: 7. How many boys are in the class if there are 45 students?

Dmitry [639]

9514 1404 393

Answer:

Step-by-step explanation:

Rearranging the given ratio, we can find the ratio of boys to the total.

boys : (boys +girls) = 7 : (7+8) = 7 : 15

Then the number of boys is ...

(7/15)(45) = 21

There are 21 boys in the classroom.

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y−x=−12

rodikova [14]

First isolate the "y" in the equation.

2y - x = -12 Add x on both sides

2y - x + x = -12 + x

2y = -12 + x Divide 2 on both sides to get "y" by itself

$y = \frac{-12 +x}{2}$

$y = -6 + \frac{x}{2}$

Your slope is $\frac{1}{2}$ .

For the equation of the line to be parallel to the given equation, the slopes have to be the same. So the parallel line's slope is also $\frac{1}{2}$

y = mx + b

$y = \frac{1}{2}x + b$

To find "b", you plug in the point (18,2) into the equation

$y = \frac{1}{2}x + b$

$2 = \frac{1}{2}(18) + b$

2 = 9 + b Subtract 9 on both sides

2 - 9 = 9 - 9 + b

-7 = b

Your equation is:

$y =\frac{1}{2}x - 7$
