A, B & C form a triangle where Z BAC = 90°. AB = 2.7 mm and CA = 5.3 mm.
Find the length of BC, giving your answer rounded to 1 DP.
BC = mm

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the answer.

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
