Answer:

c= 9

Step-by-step explanation:

first you would need to get the variable alone

next you would take the one and since it is subtraction you would do the opposite addition

then you would add one to each side and the two ones cancel each other out so the you add 8 and 1 and get nine so c would equal 9

Steps to solve:

c - 1 = 8

~Add 1 to both sides

c - 1 + 1 = 8 + 1

~Simplify

c = 9

Best of Luck!

What is the discontinuity of the function f(x)=x^2-3x-28/x+4?

Hitman42 [59]

Answer:

Option D is correct that is (-4,-11).

Step-by-step explanation:

We have been given an expression:

$f(x)=\frac{x^2-3x-28}{x+4}$

We need to find the points of discontinuity

We will first factorize the given expression

$\frac{x^2-7x+4x-28}{x+4}$

$\Rightarrow \frac{x(x-7)+4(x-7)}{x+4}$

$\Rightarrow \frac{(x+4)(x-7)}{x+4}$

Hence, the point of discontinuity is where denominator gives value zero

So, $x+4=0\Rightarrow x=-4$

Point of discontinuity is -4

hence, after removing the point of discontinuity the function left is:

$f(x)=x-7$

Hence, put x=-4

$f(-4)=-4-7=-11$

Therefore, option D is correct that is (-4,-11).

The ratio of Holly's age to that her aunt is 4:9. When holly was born her aunt was 15 years old. How old is holly's aunt now?

Lyrx [107]

Answer:

27 years

Step-by-step explanation:

Let Holly's age be h and Aunt's age be a. We can setup 2 equations and solve.

1. $\frac{h}{a}=\frac{4}{9}$

2. a - 15 = h

We can plug in equation 2 into equation 1 to solve for aunt's age:

$\frac{h}{a}=\frac{4}{9}\\\frac{a-15}{a}=\frac{4}{9}\\9(a-15)=4a\\9a-135=4a\\5a=135\\a=\frac{135}{5}=27$

Holly's aunt's age is 27
