Solve the system of equations by substitution

scoundrel [369]

Answer:

(x, y) = (1, 3)

Step-by-step explanation:

given the 2 equations

x + y = 4 → (1)

y = 3x → (2)

Substitute y = 3x into (1)

x + 3x = 4

4x = 4 ( divide both sides by 4 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

y = 3 × 1 = 3

solution is (1, 3 )

Limits of a Function

Novay_Z [31]

We are given the equation:

$\lim_{x \to 1} \frac{f(x)-8}{x-1} = 10$

which can be rewritten as:

$\frac{\lim_{x \to 1}[f(x)-8]}{\lim_{x \to 1}[x-1]} = 10$

$\lim_{x \to 1}[f(x)-8] = 10*\lim_{x \to 1}[x-1]$

$\lim_{x \to 1}[f(x)-8] = \lim_{x \to 1}[10x-10]$

which means that..

$f(x) - 8 = 10x - 10$

$f(x) = 10x - 10 + 8$

$f(x) = 10x - 2$

Finding the limit:

 $\lim_{x \to 1} f(x) = \lim_{x \to 1} (10x - 2)$ 

 $\lim_{x \to 1} f(x) = 10(1) - 2$ 

 $\lim_{x \to 1} f(x) = 8$
