Answer:
By definition, Proportional relationships have the following form:
y=kxy=kx
Where "k" is the Constant of proportionality.
By definition the graph of a proportional relationship is a straight line that passes through the origin (Point (0,0)(0,0) ).
Knowing this and having the relationship provided in the exercise, you can identify from the table that when:
x=0x=0 , y=32y=32
Then, the line does not pass through the origin, so you can conclude that the relationship between the temperature scales is not proportional.

How much does the refrigerator cost?
Answer: $535
Step-by-step explanation
He will be able to buy the refrigerator with the amount he deposited ($500) plus the interest generated from it ($35)(which we get by doing the following):
So the formula for interest is
Interest = (principal ×interest rate × time for which the money was deposited) / 100
Interest = ?
Principal = $500
Interest rate = 7%
Time = 1 year
Now
Interest = (500 × 7 × 1) / 100
Interest = 3500/ 100
Interest = $35
So the refrigerater's cost = 500 + 35
Cost = $ 535

Supposed (4.2 s, 9.6 ft) and (6.7 s, 12.3 ft) are points on a graph of a linear function.
What is the slope of the graph in decimal form.
The slope of the graph in decimal form is 1.08.
By geometry we know that a line can be constructed after knowing the location of two distinct points. Lines in explicit form are defined by slope and intercept, the former is calculated by the secant line equation and the intercept by solving a linear function.
If we know that [tex](x_{1}, y_{1}) = (4.2, 9.6)[/tex] and [tex](x_{2}, y_{2}) = (6.7, 12.3)[/tex], then the slope of the graph is:
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m = \frac{12.3-9.6}{6.7-4.2}[/tex]
[tex]m = 1.08[/tex]
The slope of the graph in decimal form is 1.08.

Answer:
Step-by-step explanation:
Domain means what is the lowest value of x on the graph and what is the highest. Our graph begins at an x value of -5 (but -5 is not included because the dot is not filled in) and goes all the way up to 2 (but 2 is not included either since the dot is not filled in. Therefore, the domain is
D = {x | x ∈ R, -5 < x < 2}
which means that the domain is in the set of real numbers that begin at -5 and end at 2, neither included.

Write an equation for the following real life scenario.
Use "t" to represent your variable.
Jasmine's cell phone company charges her $35 a month for phone service plus 0.50 for each text message. Her
total bill for the month was $51.
Answer:
[tex]35+0.50t=51[/tex]
Step-by-step explanation:
Since the $35 is a one-time fee, 0.50 is the rate, t is the variable, and 51 is the total bill, we can form the equation:
[tex]35+0.50t=51[/tex]
Answer:
0.50t+35=51
Step-by-step explanation:
0.50 is the amount for each text message so it becomes 0.50t (0.50 × text message). This is added to the monthly cost which is 35 dollars (+35) the question wants an equation as the answer so (=51).

(i) −2/ 5 < −1 /5 since -2 < -1 and denominators are same(ii) −5/ 7 < −3 /7 since -5 < -3 and denominators are same(iii) 2 /9 > −5 /11 as comparing negative and positive numbersStep-by-step explanation:
-2/5 and -1/5
Since -1 > -2
So, -2/5 < -1/5
(ii) -5/7 and -3/7
Since -5 < -3
So, -5/7 < -3/7

if you make $391 for 17 hours how much would you make in 13 hours
Answer:
We would make $299 in 13 hours.
Step-by-step explanation:
Hi there!
We're given:
⇒ We make $391 in 17 hours
To find how much we make in 13 hours, we must first find how much we make in 1 hour. Divide $391 by 17 hours:
391 ÷ 17 = 23
Therefore, we make $23 in 1 hour.
Multiply $23 by 13 hours to find how much we would make in 13 hours:
23 × 13 = 299
Therefore, we would make $299 in 13 hours.
