21 is the correct answer

(x - 3) - 5 = 13 Leave the term with x on the left hand side.

x - 3 - 5 = 13 When the sign crosses over the equality sign, it changes

x = 13 + 3 + 5

x = 21

I hope this helps.

My son wants to make and equilateral triangle eith sticks and strings. Explain how he could do this?

Ivanshal [37]

Answer:

Step-by-step explanation:

1. Cut six desired measures of string to properly wrap and tied around each end of the three sticks

2. Once fastened, bring two of the sticks together making one the bottom (base) and the other a side (angle).

3.Cut a tiny piece of rope to interlock with the rope you already have tied on the ends.

4.Tie the ends together with the new cut of string and make your desired angle as you tighten it.

5. Mirror Step 4 for the other end of the bottom stick (base), while most importantly mirroring the desired angle of step 4.

This should give you a proper equilateral triangle made out of sticks and string or anything of these two materials.

Identify the domain and range of each function. Make sure to provide these answers using inequalities.

yulyashka [42]

Answer:

a. Domain: (-∞, ∞)

Range: (0,∞)

b. Domain: (-∞, ∞)

Range: (0,∞)

c. Domain: (-∞, ∞)

Range: (-∞,0)

d. Domain: (-∞, ∞)

Range: (-∞,0)

e. Domain: (-∞, ∞)

Range: (0,∞)

Step-by-step explanation:

$a. y= 3(2)^x \\b. y= 7(0.4)^x \\c. y = -2(0.6)^x \\d. y = -3(4)^x \\e. y = 2(22)^x$

These equations are all exponential functions. Exponential functions are curves which approach a horizontal asymptote usually at y=0 or the x-axis unless a value has been added to it. If it has, the curve shifts. None of these have that and their y - values remain between 0 and ∞. This is the range, the set of y values.

However, the range of exponentials can change based on the leading coefficient. If it is negative the graph flips upside down and its range goes to -∞. C and D have this. Their range is (-∞, 0)

In exponential functions, the x values are usually not affected and all are included in the function. Their domain is (-∞, ∞). All of these equations have this domain.

a. Domain: (-∞, ∞)

Range: (0,∞)

b. Domain: (-∞, ∞)

Range: (0,∞)

c. Domain: (-∞, ∞)

Range: (-∞,0)

d. Domain: (-∞, ∞)

Range: (-∞,0)

e. Domain: (-∞, ∞)

Range: (0,∞)
