Question

So how do i do like Rule: y=x+3 and the boxes are like X Y ? 4 ? 8 ? 5 like how

Answer 1

Answer:

X: 1  5  2

Y: 4  8  5

Step-by-step explanation:

Given

$Rule: y = x + 3$

X: ?  ?  ?

Y: 4  8  5

Required

Fill in the ?'s

We have that:

$y = x + 3$

When y = 4; the rule becomes

$4 = x + 3$

Subtract 3 from both sides

$1 =x$

$x =1$

When y = 8; the rule becomes

$8 = x + 3$

Subtract 3 from both sides

$5= x$

$x =5$

When y = 5; the rule becomes

$5 = x + 3$

Subtract 3 from both sides

$2 = x$

$x = 2$

So, the complete table is:

X: 1  5  2

Y: 4  8  5
