a LINEar function has well, the graph of a straight line, so this isn't that.
is it a relation? well, yes, because the y-value correlates with the x-value, so one depends or relates to the other.
is it a non-linear function? well, a function has to pass the <u>vertical line test</u>, meaning if we draw vertical lines they must touch the graph only once on their way down.... and in this case it seems they do, so it is non-linear clearly, and it's also a function.
Answer:
Mary- $18
Jane- $30
Step-by-step explanation:
Add the numbers in the ratio together to get 8, and multiply 8 by the variable of x. Divide the total amount of money that both girls earned by 8. You will get x=6. Multiply 6 by 3 to get the amount of money Mary earned, which is 18, and multiply 6 by 5 to get the amount of money Jane earned, which is 30.
x(3+5) = $48
3x + 5x = $48
8x = $48
8x/8 = $48/8
x = $6
3($6):5($6) = $18:$30
The lengths of the diagonals are 16 and 48 feet.
To find the area of a kite, you multiply the lengths of the diagonals by each other and divide by 2. All we need to do is fill in the information in the formula and solve for the missing side.
A = pq/2
384 = (x(3x))/2
768 = 3x^2
256 = x^2
16 = x
Now, just multiply this diagonal of 16 by 3 to find the other diagonal of 48.
You'd solve it like this
6y-3 (4/3y-2)
6y-4y+6 (use the distributive property and multiply all the numbers inside the parentheses by -3)
2y+6 (add like terms)
That's pretty much it
