Bob has some 10 lb weights and some 3lbs weights. together, all his weight add up to 50 lbs. if x represents the number of 3 lb weights and y represents the number of 10 on weights, which equation can be used to find the number of each type of weight bob has?

You can write the equation as 50 = 3x + 10y or the other way around 3x +10y = 50

Hope it helps (:

ok

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.
