Answer:
We know that, two quantities are proportional when they vary directly with each other.
i.e. quantities x and y are proportional when they have the relation y = kx, where k is any constant called constant of proportionality.
Since, the quantities are in relation y = kx.
So, for x = 0 we get that the value of y = 0.
As, the point ( 0,0 ) satisfies this relation i.e. it is a solution of y = kx.
Hence, in proportional relationship, the graph will pass through ( 0,0 ).
Answer:
D. x + 2y² - 7
Step-by-step explanation:
it because it has 3 terms
We can subsitute since
23x+4=y and
4-2x=y
therefor
23x+4=y=4-2x
so
23x+4=4-2x
minus 4 on both sides
23x=-2x
add 2x to both sides
25x=0
divide both sides by... uh oh
I guess x=0
sub
4-2(0)=y
4-0=y
4=y
the solution is (0,4)
Answer:
59 cups ;
10 cups
Step-by-step explanation:
Given that he fitted model :
c = 2t - 89
Where, c = cups of lemonade sold ; t = high temperature
On a day when high temperature is 74 degrees ; cups of lemonade sold
Hence,
c = 2t - 89
c = 2(74) - 89
c = 148 - 89
c = 59 cups
Sunday is expected to be 5 degree warmer than on Saturday :
The number of cups sold on Sunday using the fitted model should be :
Difference in temperature between Saturday and Sunday multiplied by the slope value
Slope value from the model = 2
Temperature difference = 5
Difference in Number of cups :
2 * 5 = 10 cups
Number of lemonade sold on Sunday will be 10 cups more than that sold on Saturday
