Answer:
option ( c ) is correct !!
Step-by-step explanation:
Given equations :-
y = -6x + 9 ________ ( i )
y = -3x + 3 .....( ii )
Equating both i and ii
-6x + 9 = -3x + 3
-6x + 3x = 3-9
-3x = -6
x = -6/-3
x = 2
Also, y = -3x + 3
y = -3(2) + 3
y = -6 + 3
y = -3
So, ( x , y ) = ( 2 , -3 )
Okay... so the y intercept it automatically 9. so that's out of the way. Now you narrow it down to a or b. the first number, with x is -3x. Thats your slope. easy as that
Answer:
44fps, or 44:1
Step-by-step explanation:
it is already a unit rate
b.
Bedroom area
Lenght = 5 squares
= 5 × 1/4 inchi
= 5/4 inchi
Width = 4 squares
= 4 × 1/4 inchi
= 1 inchi
Large area = 5/4 × 1 inchi
= 5/4 inchi
Living room
Lenght = 7 squares
= 7 × 1/4 inchi
= 7/4 inchi
Width = 4 squares
= 4 × 1/4 inchi
= 1 inchi
Large area = 7/4 × 1 inchi
= 7/4 inchi
Total Area
Bedroom area + Living room area
= 5/4 + 7/4
= (5+7)/4 inchi
= 12/4 inchi
= 3 inchi
1 square yard = 1296 square inches
so 1 square inches = 1/1296 square yard
3 inchi = 3×1/1296
= 3/1296
= 1/432
Cost = 1/432 × $18
= $1/24
It would cost $1/24 to carpet the bedroom and living room.
