Diego has 81 square inch tiles. He wants to use them to make a square mosaic. How long can each side of the mosaic be

s= 9

Step-by-step explanation:

Diego has 81 square inch tiles. He wants to use to make a square mosaic.

Area of the tile = 81 square inches

We know , area of the square = s^2

where 's' is the side of the square

Area is s²

Plug in 81 for area and solve for 's'

Take square root on both sides

s= 9

i hope this helps

have a great day :))

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
