Consider Functions F and G

Zanzabum

Answer:

Step-by-step explanation:

We are given two functions:

$\displaystyle f(x)=\frac{x-16}{x^2+6x-40}\text{ and } g(x)=\frac{1}{x+10}$

And we want to find:

$f(x)+g(x)$

Thus:

$\displaystyle =\frac{x-16}{x^2+6x-40}+\frac{1}{x+10}$

We can factor the denominator of the first term:

$\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}$

In order to add the two terms, we must have a common denominator. To achieve this, we can multiply to second term by (x - 4). Therefore:

$\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{1}{x+10}\Big(\frac{x-4}{x-4}\Big)$

Multiply:

$\displaystyle =\frac{x-16}{(x+10)(x-4)}+\frac{x-4}{(x+10)(x-4)}$

Combine:

$\displaystyle =\frac{(x-16)+(x-4)}{(x+10)(x-4)}$

Simplify:

$\displaystyle =\frac{2x-20}{(x+10)(x-4)}$

We can expand the denominator:

$\displaystyle =\frac{2x-20}{x^2+6x-40}$

Therefore, our answer is A.

A triangle has ∠1 and ∠2 as remote interior angles with respect to exterior angle ∠3. Given that m∠1 = 50 and m∠2 = 70, Alicia r

11111nata11111 [884]

Answer:

No, 60 is the third interior angle's mesure, not the exterior ∠3.

Step-by-step explanation:

Say that ∠1=∠A=50 and ∠2=∠B=70. The remote interior angles are the angles that are not touvhing the exterior angle. So ∠3 would be the the exterior angle to ∠C. ∠C=60 as the sum of the interior angles is 180.

The exterior angle is the angle formed by extending one of the triangle's sides. A straight line has the angle 180, so∠3=180-∠C=180-60=120.

9/10 = z/8 round to the nearest tenth

jeka57 [31]

9/10 = z/8

cross multiply

9/10(10)(8) = z/8(8)(10)

9(8) = z(10)

72 = 10z

Isolate the z, divide 10 from both sides

72/10 = 10z/10

z = 72/10

z = 7.2

7.2, or D) is your answer

hope this helps
