Answer: D) -2 |x| - 2

Step-by-step explanation:

A v-shaped graph is an absolute value graph.

The general form of an absolute value equation is: y = a |x - h| + k

where (h, k) represents the vertex and "a" represents the vertical stretch (aka slope).

The vertex of the given graph is (0, 2), however the graph is inverted (upside-down) which is a reflection across the x-axis. Therefore,

a = -2
(h, k) = (0, -2)

B) A(t) = 106260

Step-by-step explanation:

A) 5000 is the initial amount, 1 + 0.012 is the interest rate, and t represents the years.

B) When we plug 21 into the equation, we get 106260.

Answer:

Step-by-step explanation:

If e = 7, you would replace e in the expression e - 2 with 7 so that the expression becomes 7 - 2 which results in 5.

Rewrite as a simplified fraction.

Kitty [74]

The simplified fraction is $\frac{25}{3 }$ .

Solution:

Given expression:

$3.8 \overline{3}$

$3.8 \overline{3}=8.33333...$

Let x = 8.33333... -------- (1)

Multiply by 10 on both sides.

10x = 83.3333... -------- (2)

Subtract (1) from (2),

10x - x = 83.3333... - 8.33333...

9x = 75

Divide by 7 on both sides, we get

$$x=\frac{75}{9}$

$$x=\frac{25\times 3}{3 \times 3}$

Cancel the common factor 3.

$$x=\frac{25}{3 }$

$$ 3.8 \overline{3}=\frac{25}{3 }$

Hence the simplified fraction is $\frac{25}{3 }$ .
