Answer:

Step-by-step explanation:

---------

7 | 62 03

----------

148 | 13 03

11 84

-----------

78^2 = 6084.

We observe that 78^2 < 6203.

79^2 = 6241.

We observe that 79^2 > 6203.

Hence the number to be added to 6203 is 6241 - 6203 = 38.

6203 + 38 = 3241

= 79 * 79

= 79.

Therefore 38 should be added to 6203 to obtain a perfect square.

$If\ Z\ is\ directly\ proportional\ to\ X\ then\ \frac{Z}{X}=const.\\------------------------\\X=15\ and\ Z=45\\\\X=23\ and\ Z=?\\\\\frac{Z}{23}=\frac{45}{15}\to\frac{Z}{23}=3\ \ \ \ |multiply\ both\ sides\ by\ 23\\\\\huge\boxed{Z=69}$

Step-by-step explanation:

Step 1: Define

Find points from graph.

Point (0, 3)

Point (10, 8)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute [SF]: $m=\frac{8-3}{10-0}$
Subtract: $m=\frac{5}{10}$
Simplify: $m=\frac{1}{2}$
