The grid of numbers with a row and column sum of 30 is
3 15 12
17 11 2
10 4 16
<h3>How to prepare the grid?</h3>
The grid in the question has a row sum and column sum of 15
The question implies that we create a similar grid with a row sum and column sum of 30
Represent the grid as follows:
a b c
d e f
g h j
So, we have the following sum of rows
a + b + c = 30
d + e + f = 30
g + h + j = 30
And, we have the following sum of rows
a + d + g = 30
b + e + h = 30
c + f + j = 30
Using trial by error, we have:
3 + 15+ 12 = 30
17 + 11 + 2 = 30
10 + 4 + 16 = 30
When the columns are added, we have
3 + 17 + 10 = 30
15 + 11 + 4 = 30
12 + 2 + 16 = 30
Hence, the grid of numbers is
3 15 12
17 11 2
10 4 16

#SPJ1
The domain is the set of all numbers. The range is also the set of all real numbers.
Why is this the case? Because the line extends forever in both directions along the x and y axis. We can plug in any x value and solve for y, or vice versa, and we don't have any restrictions for the input or output.
-----------------------
To write "the set of all real numbers" in interval notation, you would write 
This is the interval from negative infinity to positive infinity, spanning the entire real number line.
A
given that y varies directly as x, then the relationship is
y = kx ← k is the constant of variation
To find k use the given condition x = 3 when y = 24
y = kx ⇒ k =
=
= 8
y = 8x
Hello,
Answer C
center (0,0)
b=3
c=7==>a²=c²+b²=49+9=58
x²/58+y²/9=1
