non-proportional
Step-by-step explanation:
Given equation:
[tex]y=x+3[/tex]
Create a table of ordered pairs using the given equation:
[tex]\begin{array}{| c | c | c |}\cline{1-3} x & x+3 & y\\\cline{1-3} -3 & -3+3 & 0\\\cline{1-3} -2 & -2+3 & 1\\\cline{1-3} -1 & -1+3 & 2\\\cline{1-3} 0 & 0+3 & 3\\\cline{1-3} 1 & 1+3 & 4\\\cline{1-3} 2 & 2+3 & 5\\\cline{1-3}\end{array} \implies \begin{array}{| c | c |}\cline{1-2} x & y\\\cline{1-2} -3 & 0\\\cline{1-2} -2 & 1\\\cline{1-2} -1 & 2\\\cline{1-2} 0 & 3\\\cline{1-2} 1 & 4\\\cline{1-2} 2 & 5\\\cline{1-2}\end{array}[/tex]
Graph
As the given equation is linear, plot two of the ordered pairs and draw a straight line through them. (See attachment).
Proportional Relationship
A relationship in which two quantities vary directly with each other.
y varies directly as x:
[tex]y=kx[/tex]
(where k is some constant)
To find if the relationship is proportional using the table, find the ratio [tex]\dfrac{y}{x}[/tex] of each row. If the ratio is the same, the relationship is proportional.
[tex]\begin{array}{| c | c | c |}\cline{1-3} x & y & \dfrac{y}{x}\\\cline{1-3} -3 & 0 & 0\\\cline{1-3} -2 & 1 & -0.5} \\\cline{1-3} -1 & 2 & -2 \\\cline{1-3} 0 & 3 & \text{-}\\\cline{1-3} 1 & 4 & 4\\\cline{1-3} 2 & 5 & 2.5\\\cline{1-3}\end{array}[/tex]
Graphs of proportional relationships pass through the origin (0, 0).
Therefore, the relationship is non-proportional because:
The ratios of y/x of each row of the table are not the same.The graph does not pass through the origin.There is the addition of a constant in the given equation, which means that y does not vary directly as x.A riverbank has been colonized by mink.

Answer:

Step-by-step explanation:
The formula for area of a rectangle is A= length times width. They gave you the area of the entire rectangle. But because this is a shape with a cutout, you still need the area of the missing section.
A= 1*4 = 4 units
Now subtract that from 49.
A=49 - 4= 45 square units
Answer:
49-4 = 45
Step-by-step explanation:

is this a function?
ignore the graph above the one with the dots lol
Answer:
No.
Step-by-step explanation:
Use a vertical line test.
Vertical line test: If you can draw a vertical line and it does not cross two points in the line, then it is a function.
So, we draw a line.
Draw it through 9,0
It intercepts two points so No. This is not a function.
Hope this helps plz hit the crown :D

Mary borrowed $840 from her friend to help pay for a trip. She paid him $40 every
week until the debt was paid.
How many weeks did it take Mary to pay her debt?
A. 40
B. 35
C. 32
D. 21
Answer:
d.21
Step-by-step explanation:
840/40=21
Answer:
21 Weeks
Step-by-step explanation:
$840 ÷ 4 weeks = 21
You can also reverse work this by multiplying $40 by the other choices!
$40 x 40 = $1600
$40 x 35 = $1400
$40 x 32 = $1280
$40 x 21 = $840
As we can see, D is the only answer that makes sense, therefore 21 weeks is the answer.

1 Evaluate the expression 2a + b - 3 when a=5 and b=2. Please click on "show your work" to set up the problem and show your work. Then, enter your answer in the box to the right. You must complete both of these steps.
Answer:
9
Step-by-step explanation:
From the question,
We are to evaluate the expression : 2a + b - 3 when a=5 and b=2.
We substitute 5 for a and 2 for b in the given expression
2a + b - 3
= 2(5) + 2 - 3
= 10 + 2 - 3
= 12 - 3
= 9

Answer:
x = -8

Step-by-step explanation:
Step 1: Define Equation
x + 5 = -3
Step 2: Solve for x
Subtract 5 on both sides: x = -8Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: -8 + 5 = -3Add: -3 = -3Here we see that -3 does indeed equal -3.
∴ x = -8 is the solution to the equation.
Answer:
[tex]x=-8[/tex]
Step-by-step explanation:
Subtract 5 from both sides.
[tex]x=-3-5[/tex]
Simplify [tex]-3 -5[/tex] to [tex]-8[/tex]
[tex]x=-8[/tex]
let check if the answer is correct
[tex]x+5=-3[/tex]
Let [tex]x=-8[/tex]
[tex]-8+5=-3[/tex]
Simplify [tex]-8+5[/tex] to [tex]-3[/tex]

A plumber charges a one-time fee of $50 plus a fixed hourly rate (h) in dollars. The plumber works at a customer's house for 2 hours and charges a total of $100. Find the hourly rate the plumber charges.
Answer:
$25 an hour
Step-by-step explanation:
use this equation y = hx + 50
y is the money earned and x is the hours worked
plug in 100 for y and 2 for x
100 = 2h + 50
solve for h
50 = 2h
25 = h
he charges $25 an hour

The student council sold jars of mixed nuts at their bazaar they were given 40 empty jars. They paid $19.60 for the nuts and $11.20 for decorative ribbon they made a profit of 98￠on each of the 40 jars sold. How much did they charge for each jar
Answer:
[tex]\$1.75[/tex]
Step-by-step explanation:
Total amount paid for the nuts is $19.60
Total amount paid for the ribbons is $11.20
Profit made on each jar is 98￠= $0.98
Cost price of the nuts and ribbon for the 40 jars is [tex]19.6+11.2=\$30.8[/tex]
Cost price for nuts and ribbonn for one jar = [tex]\dfrac{30.8}{40}=\$0.77[/tex]
Selling price is the sum of the cost price and profit.
Selling price for one jar = [tex]0.77+0.98=\$1.75[/tex]
They charged [tex]\$1.75[/tex] for each jar.
