Use Functions Involving E Algebra 2 Lesson 7.3

1) Solving Equations: X+B = C Solve for x:x + 3 = -1

X = -5

X = -8

X = -4

X = 9

To solve the equation x + 3 = -1, we need to isolate x on one side of the equation. To do this, we can subtract 3 from both sides of the equation. This will give us x = -4 as the solution.

Explanation

To solve the equation x + 3 = -1, we need to isolate x on one side of the equation. To do this, we can subtract 3 from both sides of the equation. This will give us x = -4 as the solution.

2) Solving Equations: X+B = C Solve for x:x + 7 = 9

X = 1

X = 2

X = 3

X = 8

To solve the equation x + 7 = 9, we need to isolate the variable x. By subtracting 7 from both sides of the equation, we get x = 2. This is the correct answer because when we substitute x = 2 back into the original equation, we get 2 + 7 = 9, which is true.

Explanation

To solve the equation x + 7 = 9, we need to isolate the variable x. By subtracting 7 from both sides of the equation, we get x = 2. This is the correct answer because when we substitute x = 2 back into the original equation, we get 2 + 7 = 9, which is true.

3) Solving Equations: AX = C Solve for x:8x = 4

X = 1/2

X = 0

X = 3/2

X = 3/8

To solve the equation 8x = 4, we need to isolate x. We can do this by dividing both sides of the equation by 8. This gives us x = 4/8, which simplifies to x = 1/2. Therefore, the correct answer is x = 1/2.

Explanation

To solve the equation 8x = 4, we need to isolate x. We can do this by dividing both sides of the equation by 8. This gives us x = 4/8, which simplifies to x = 1/2. Therefore, the correct answer is x = 1/2.

4) Solving Equations: AX = C Solve for x:-6x = -2

X = -7/3

X = -5/2

X = 1/5

X = 1/3

The correct answer is x = 1/3 because when we divide both sides of the equation -6x = -2 by -6, we get x = 1/3.

Explanation

The correct answer is x = 1/3 because when we divide both sides of the equation -6x = -2 by -6, we get x = 1/3.

5) You deposit $2500 in an account that pays 5% annual interest compounded continuoiusly. Find the balance after 2 years.

$3002.17

$4280.63

$2603.86

$2762.93

A=2500e^0.05(2)

Explanation

A=2500e^0.05(2)

6) If I wanted to shift two units to the right I would...

Change the x to (x-2)

Change the x to (x+2)

Add 2 to the end of the equation

Subtract 2 to the end of the equation

A right or left translation changes the exponent. The sign need to be a negative so x-2 would give me a +2 shift. An up or down translation is produced by adding or subtracting a number after the equation.
