Answer:

see explanation

Step-by-step explanation:

Given

\frac{9}{a^2+9a+20} , \frac{7a}{a^2+11a+28}

Factor the denominators of both fractions

\frac{9}{(a+4)(a+5)} , \frac{7a}{(a+4)(a+7)}

The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)

Multiply numerator/denominator of first fraction by (a + 7)

Multiply numerator/denominator of second fraction by (a + 5 )

\frac{9(a+7)}{(a+4)(a+5)(a+7)} , \frac{7a(a+5)}{(a+4)(a+5)(a+7)} , then

\frac{9a+63}{(a+4)(a+5)(a+7)} , \frac{7a^2+35a}{(a+4)(a+5)(a+7)}

Solve the following system of equations using the substitution method.
BartSMP [9]

Answer:

B

Step-by-step explanation:

First label the equations.

6x +3y= 18 -----(1)

y= -2x +5 -----(2)

subst. (2) into (1):

6x +3(-2x +5)= 18

6x +3(-2x) +3(5)= 18 (expand)

6x -6x +15= 18

15= 18 (simplify)

(reject)

There is no solution.

<u>Further explanation</u><u>:</u>

If I rewrite the first equation into the form of y=mx+c, I would get

6x +3y=18

3y= 18 -6x (bring y term to one side)

y= 6- 2x (÷3 throughout)

y= -2x +6

Notice that the gradients of both lines are equal ( -2). This implies that they are parallel to each other and will never meet. Hence there are no solutions.
