Answer:
A store is offering a 14% discount on all items. Write an equation relating the sale price S for an item to its list price L.
Step-by-step explanation:
Yes there is a proportional relationship between the original price of an item and its price after the discount assuming a store is offering a 20% discount on all items
Let p represent original price of the commodity
Let the current price be:
Current price (p1)=Original price-Discount amount
Current price (p1)=P-Px20%)
Current price (p1)=p(1-20%)
Current price (p1)=0.8P
Hence:
P1=0.8P
P1÷P=0.8
Based on the above there is a proportional relationship between the original price of an item and its price after the discount.
Inconclusion Yes there is a proportional relationship between the original price of an item and its price after the discount assuming a store is offering a 20% discount on all items.

6. In a jar of 650 marbles, 20% of the marbles are red.
How many marbles are not red

20% of 650
1/5 of 650
130=red
520= not red
Answer:
520
Step-by-step explanation:
20% are red which means 130 are red
650-130= 520
or you could look at it this way
if 20% is red that means 80% is not red
80% of 650 is 520

What is the equation, in slope-intercept form, of the line with a slope of -1/3 and y-intercept of (0, 9)? Choices in picture below
Step-by-step explanation:
The formula is y=mx+b, with m representing the slope, x representing the x coordinate, and b representing the y-intercept. Since -⅓ is the slope, that means that the equation starts off as y=-⅓. We know that the y-intercept is where the line meets the y-axis, so the y-intercept is 9. Since 9 (the y-intercept) is being added, that means the equation is y=-⅓+9.
Answer:
y=-⅓+9

How many kilograms of rice will each person get if 6 people share 1-2 of a kilogram of rice equally?
Answer:
1/12
Step-by-step explanation:
So if a man has 1/2 kg of rice then he shares to 6 people equally.
So all you have to do is just take the total amount of rice then divide it to 6 people.
So 1/2 ÷ 6 equals to 1/12 in fraction form.

Give an example of a two variable function that is not continuous at (1,2) . Explain why your example works.
Answer:
A two-variable function is something like:
z = f(x, y).
We want this function to not be continuous at (1, 2), this means that x = 1 and y = 2.
Now, a easy way to make a function not continuous at a given point, we can have a denominator that is equal to zero at that particular point, and this is because we can not divide by zero
For example, we could have:
[tex]f(x, y) = \frac{1}{(x - 1) + (y - 2)}[/tex]
The denominator is (x - 1) + (y - 2)
When x = 1, and y = 2, this is equal to zero, then this function is not continuous in the point (1, 2).

The equations 3x-2y=-14 and 3x+y=-11 are plotted on the same set of axes. what are the coordinates of a point that's common to both equations? how do you know?
Answer:
14
Step-by-step explanation:
Answer:
(-4, 1)
Step-by-step explanation:
Solve it as a system of equations:
[tex]3x-2y=-14\\3x+y=-11[/tex]
subtract the two equations
[tex]-3y = -3[/tex]
divide both sides by -3
[tex]y=1[/tex]
Plug this into the equation 3x + y = -11 to solve for x
[tex]3x + 1 = -11\\[/tex]
subtract 1 from both sides
[tex]3x = -12[/tex]
divide both sides by 3
[tex]x = -4[/tex]
So the answer is (-4, 1)
