Mrs. Jones husband thought he could fix the clogged sink drain. In doing so he lost the drain snake down the pipe and had to call a plumber. Roto-Rooter charged a $50 home visit fee and an hourly rate of $35 an hour.
Write an equation in slope-intercept form to represent the total cost of the plumbers fees.
y represents the total cost and x represents the number of hours.
Write another equation where t represents the total cost and h represents the number of hours.
What does the y-intercept represent in this problem?
What does the slope represent in this problem?
The plumber was at Mrs. Jones house for 4 hours. What is the total cost for the plumbers visits?
For lunch with her friend, Kristionna is purchasing several side items that cost a total of $18, plus 2 sandwiches. The total cost of the meal is $32 and is represented by the equation 2x + 18 = 32. How much does each sandwich cost?
A) $14
B) $22
C) $7
D) $28
Answer:
C
Step-by-step explanation:
thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.
First, subtract 18 from both sides to eliminate it.
2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14
Next, separate the 2 from the x by dividing it from both sides:
2x = 14 ----> 2x/2 = 14/2 ----> x = 7
By solving this equation, we find that x, or one sandwich, costs $7.
At a school carnival, tickets can be purchased to participate in different activities. The table shows the total cost for different numbers of tickets.
What is the constant of proportionality that relates y , the total cost in dollars, to x , the number of tickets purchased?
PLZ I HAVE TO FINISH THIS TEST TODAYYY
Answer:
4 tickets for $1
Step-by-step explanation:
I just divided 8 with 2.00 and got 4.
The value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.
What is a proportional relationship?It is defined as the relationship between two variables when the first variable increases, the second variable also increases according to the constant factor.
It is given that:
At a school carnival, tickets can be purchased to participate in different activities.
The data are shown in the picture.
From the data:
y ∝ x
Removing the proportional sign:
y = kx
Plug x = 8
y = 2
2 = 8k
k = 1/4
Thus, the value of the constant of proportionality that relates y, the total cost in dollars, to x, the number of tickets purchased is 1/4.

Look at this inequality: 12−4x ≤ 20
Which of these shows the solution to this inequality?
Question options:
Answer: The last line is the answer
12 - 4x < 20
20 - 12 = 8
-4x = 8
-4/4 = 8/-4
x = -2
New inequality: x > -2
Step-by-step explanation:
The correct option is d. The solution to the linear inequality 12 - 4x ≤ 20 is x ≥ -2 by solving the inequality.
To solve this inequality, to isolate the variable x.
Step 1
subtract 12 from both sides of the inequality:[tex]12 - 12 - 4x \leq 20 - 12,[/tex]
which simplifies to[tex]-4x \leq 8.[/tex]
Step 2 :
Divide both sides of the inequality by -4. However, when divide by a negative number, the direction of the inequality sign must be flipped. So x ≥ -2, indicating that x is greater than or equal to -2.Therefore, the solution to the inequality is x ≥ -2. The correct option is d.

The solution to the following equation is x=0
6x+7= 1/2x+7
True
or
False
(The 1/2 is a fraction)
Answer:
True
Step-by-step explanation:
To see if that is the solution, lets solve the equation.
6x + 7 = 1/2x + 7
Subtract 1/2x from each side to bring it to the right
6x - 1/2x + 7 = 7
Subtract 7 from each side to bring it to the left
6x - 1/2x = 7 - 7
Simplify it
5.5x = 0
Divide 5.5 from each side to leave x alone.
x = 0
The answer is true. I hope this helps!
