Step-by-step explanation:
I'll do line A for you and you can use the formulas to solve lines B and C yourself, since its good for you to practice doing these questions yourself
a)
The gradient, m, is calculated using m = (y2-y1)/(x2-x1) where x1,x2,y1 and y2 can be any ordered pairs on the line. I'm going to use (4,0) and (7,3) as the 2 points.
m = (3-0)/(7-4) = 3/3 = 1
b)
The y-intercept is where the line intersects with the x-axis. In this case (0,-4)
c)
The equation of a linear line is y=mx+b (or c depending on which country you are from)
y = 1x-4
y=x-4
Now try the other 2 lines yourself!

128 * 9 = 1152
1152/8 = 144
So it can fill 144 cups
Answer:
true
Step-by-step explanation:
Since their wise or intelligent guess
If you are asking which ratio is equivalent to 8 then it is neither. They are both simplified to 3:1. 54/18= 3, 18/6= 3. If you were asking if they were equivalent to each other the answer is yes.
Answer:
252 cm²
Step-by-step explanation:
Lateral surface area = area of the 3 triangular surfaces (the base is not included)
Area of 1 triangular face = ½*bh
b = 12 cm
h = 14 cm
Area = ½*12*14 = 6*14
Area = 84 cm²
✅Lateral surface area = 3(84) = 252 cm²
