okay so the answer is a. and b. since how you put them they are the same. so the answer is -4 x 8
hope this helps
The -3 in f(-3) is the X coordinate, so you need to find where the line is on the Y coordinate at that point.
The line is at Y = -9
Answer:
No
Step-by-step explanation:
To calculate the number of tiles needed
divide 4m by 0.2m for row of tiles ⇒ 20 tiles per row
divide 3m by 0.2m for column of tiles ⇒ 15 tiles per column
number of tiles = 20 × 15 = 300
number of packs = 300 ÷ 10 = 30
cost = 30 × £34.99 = £1049.70
Since she has £1000 to spend and £1049.70 > £1000
She does not have enough to cover the wall
