Answer:
y = 1.6 x
y = 24
Step-by-step explanation:
The general equation of a direct variation is
y = k x
In this case
x = 10
y = 16
y = k*x
16 = 10*k
16/10 = k
k = 1.6
y = 1.6x
================
Let x = 15
y = 1.6 * 15
y = 24
Answer:
Vincent would be able to use the spa 9 more times.
Step-by-step explanation:
$135 divided by $15 = 9
(4v-3w)∧2, Its to the second power so take the exponent 2 and put it on the variables and coefficients so you would have (4∧2)(v∧2)-(3∧2)(w∧2). Then you would do the math and get 16v∧2-9w∧2 than you would add the like terms so you have 25v∧2w∧2.

Answer:
Money raised($)= 6n-50
Step-by-step explanation:
they plan to sell the hats for $10. each hat $4 to make and they spend $50 for advertising.
If their are no number of hats
Cost = 50+4n
Money gotten from the n number of hats= 10(n)
If they are to make profit, the money gotten from the sales of hats should be bigger than the total cost
Money raised = money from sales- cost
Money raised= 10n -4n-50
Money raised($)= 6n-50
