Given: 3x + 1 = -14; Prove: x = -5
MrRissso [65]

Answer:

x = -5

Step-by-step explanation:

Solve for x:

3 x + 1 = -14

Subtract 1 from both sides:

3 x + (1 - 1) = -14 - 1

1 - 1 = 0:

3 x = -14 - 1

-14 - 1 = -15:

3 x = -15

Divide both sides of 3 x = -15 by 3:

(3 x)/3 = (-15)/3

3/3 = 1:

x = (-15)/3

The gcd of -15 and 3 is 3, so (-15)/3 = (3 (-5))/(3×1) = 3/3×-5 = -5:

Answer:  x = -5

Directions: Graph each function using a table of Graph each values, then identify its key characteristics.
Tom [10]

Answer:

Step-by-step explanation:

Given function is,

y=(\frac{1}{2})^x

In the given exponential function,

Base of the function = \frac{1}{2}

By the property of an exponential function,

1). If the base is between 0 and 1, function will be a growth function.

2). If the base is greater than 1, function will be a decay function.

Therefore, given function is a decay function.

Input-output table,

x             -2                -1               0                1                 2

y      (\frac{1}{2})^{-2}=4     (\frac{1}{2})^{-1}=2     (\frac{1}{2})^{0}=1   (\frac{1}{2})^1=\frac{1}{2}      (\frac{1}{2})^2=\frac{1}{4}

By plotting these points we can get the graph of the function.

Domain: (-∞, ∞)

Range: (0, ∞)

y-intercept: 1

Asymptote: y = 0

Danny is 603/4 inches tall . His twin sister is 58 1/8 inches tall.How much taller is Danny than his twin sister.
Mazyrski [523]

Answer:

2 5/8 inches

Step-by-step explanation:

This is a subtraction problem.

You must subtract 58 1/8 inches from 60 3/4 inches.

We need a common denominator for the fractions.

The LCD of 4 and 8 is 8.

60 3/4 = 60 6/8

58 1/8 = 58 1/8

60 3/4 - 58 1/8 = 60 6/8 - 58 1/8 = 2 5/8

Answer: 2 5/8 inches
