Answer:
The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship ⇒ last answer
Step-by-step explanation:
* Lets explain how to sole the problem
- Proportional relationship describes a simple relation between
two variables
- In direct proportion if one variable increases, then the other variable
increases and if one variable decreases, then the other variable
decreases
- In inverse proportion if one variable increases, then the other variable
decreases and if one variable decreases, then the other variable
increases
- The ratio between the two variables is always constant
- Ex: If x and y are in direct proportion, then x = ky, where k
is constant
If x and y in inverse proportion, then x = k/y, where k is constant
* Lets solve the problem
# Last table
∵ x = 3 and y = 6
∴ x/y = 3/6 = 1/2
∵ x = 5 and y = 10
∴ x/y = 5/10 = 1/2
∵ 1/2 is constant
∵ x/y = constant
∴ x and y are proportion
* The ordered pairs (3 , 6) , (5 , 10) show a proportional relationship
Answer:
slope-intercept form y= -2/3 x + 490 slope is -2/3 y intercept is (0.490)
Step-by-step explanation:
2x+3y= 1470
3y= 1470-2x
y= 1470/3- 2/3 x
y= -2/3 x+ 490
slope is -2/3 and y intercept is 490 when x =0
the graph represent the amount of sandwiches that Sal's shop sold, where x is the number of sandwiches and y is the number of wraps sold. so that x won't exceed 735 sandwiches : 0≤x≤735 and 0≤ y≤490.
<u>total profit is 1593.</u>
2x+3y= 1593
y= -2/3 x + 531
similar : the two functions have the same slope -2/3
difference: 0≤ y≤531
0≤x≤796.5
the two line are parallel
