Answer:
Step-by-step explanation:
x = 1.0
how:
we know that the Hyp of the small triangle is 
since we know that , then
= 1^2 + 1^2 by Pythagoras theorem
so each side is 1 :)
The greatest commons factors are for 12 is 1,2,3,4,6,12 because 2 × 6 = 12, or 4 × 3 = 12, or 1 × 12 = 12 hope that help!
Answer:

Step-by-step explanation:
Let the weight of the bag of sand with an unknown weight be given as "x" pounds. Then, the difference between the weight of an average bag of sand which is given to be as 22.3 pounds, is given as
. Therefore, the absolute value function describing the difference between the weight of an average bag of sand and a bag of sand with an unknown weight will be given as:
.
Let us represent this by f(x) or y. And thus, we get:

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!
