Answer:
what are the given values for x?
Step-by-step explanation:
i don't know what the given values for x are
but if you know them, here's an example
let's say x=4
y=(4)+2
y=6
Answer:
To find the perimeter of a circle the equation is P = 2 * Pi * R. Pi = 3.142 and R = radius. now if you know the diameter The equation is P = Pi * D.
Step-by-step explanation:
So we plug 53 in to
P = 2 * 3.142 * R
And come out with
P = 2 * 3.142 * 53
P = 333.052
And if Lily wants to sew half of it take 333.052/2
The answer is Lily will need 167 cm of braid
I hope this helped if some a thanks and a 5 stars would be appreciated.
Have a good rest of your day.
The height of flagpole is 49.5 feet.
Step-by-step explanation:
Given,
Shadow casted by streetlight = 2 foot
Height of streetlight = 9 feet
Ratio of shadow to height = 2:9
Shadow casted by flagpole = 11 foot
Let,
x be the height of flagpole
Ratio of shadow to height = 11:x
Using proportion
Ratio of shadow to height :: Ratio of shadow to height
Product of mean = Product of extreme
Dividing both sides by 2
The height of flagpole is 49.5 feet.

Answer:
The relationship is not a function.
Step-by-step explanation:
A relation is a function if and only if for each value of the variable x there exists a single value of f(x).
This means that if for a single value of x there is more than one value of y then the relation is not a function.
For the case shown in the image we have two variables.
The variable Months on the axis of abscissas and the variable days on the axis of the ordinates.
Note that for the month of February there are 2 different values of number of days, 29 and 28. Therefore, the relationship is not a function.
Answer:
y = 2.4
Step-by-step explanation:
If y varies inversely as x, it means there's an inverse relationship between y and x, that is if x is increasing, y is decreasing and vice versa. In such instance, we have to find the constant of proportionality "k"
Hence,
y~1/x
y=k/x
When y =-6 and x =-2, we insert these values to find the value of the constant "k"
-6 = k/-2
k = 12.
Using this value of k to determine value of y when x =5 becomes:
y = 12/5
y = 2.4
