The answer is in slope form : Y=1x+5
Reason: all you do is (rise/run) to get the slope. So take (5/5)=1x (slope). Also, your intercept is +5.

Answer:
17.37
Step-by-step explanation:
y varies inversely as the square root of x
Mathematically:
y = k.root x
We first find k here
To find k, we were made to know that y is 21 and x = 361
k = y/root.x
k = 21/root. 361
k = 21/19
now what is y when x = 247
From y = k.root x
y = 21/19 * root 247
y= 21/19 * 15.72
y = 17.37
Answer:
According to the first image, 1 cupcake costs $1.5.
So, we can use the rule of three to complete the table.
If 1 cupcake costs $1.5, 5 cupcakes would be $1.5(5)=$7.50
And 18 cupcakes would be $1.5(18)=$27.
However, $18 how many cupcakes represent?
Therefore, 12 cupcakes costs $18.
So, the table would be:
Cupcakes Prices
5 $7.50
12 $18
18 $27
