To prove the sum is 4z you can say I put an imaginary 1 in front of z because we know a variable by itself always has a one.

Solve the equation. Check your solution. (1/2 is a fraction for one half <br> s-1/2=1/2
Alchen [17]

Answer:

s = 1

Step-by-step explanation:

Given

s - \frac{1}{2} = \frac{1}{2}

Required

Solve for s

s - \frac{1}{2} = \frac{1}{2}

Add \frac{1}{2} to both sides

s - \frac{1}{2} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2}

Take LCM

s + \frac{-1+1}{2}  = \frac{1+1}{2}

s + \frac{0}{2}  = \frac{2}{2}

s +0  = 1

s = 1

What is the domain and range of the step function with the equation below f(x)=-3 x
Nostrana [21]
The function f(x)=-3x follows a linear form y=ax+b, where a is the slope and b is the y-intercept. From our function:
f(x)=-3x
f(x)=-3x+0
slope, a=-3 and y-intercept is 0. This implies that the function is a linear function, thus the domain and range will be:
domain:
(-∞,∞)

Range:
(-∞,∞)

Solve the equation 18y-6y+22=11(y-2)+y
Serhud [2]

Answer:

the answer its 44=0

Step-by-step explanation:

18y-6y+22=11(y-2)+y1

We move all terms to the left:

18y-6y+22-(11(y-2)+y1)=0

We add all the numbers together, and all the variables

12y-(11(y-2)+y1)+22=0

We calculate terms in parentheses: -(11(y-2)+y1), so:

11(y-2)+y1

We add all the numbers together, and all the variables

y+11(y-2)

We multiply parentheses

y+11y-22

We add all the numbers together, and all the variables

12y-22

Back to the equation:

-(12y-22)

We get rid of parentheses

12y-12y+22+22=0

We add all the numbers together, and all the variables

44=0

are not solution for this equation

Hope helps you and have a great day !
