The sum of two numbers is -64. Their difference is -10. Find the numbers. The smaller number is:
The larger number is:

smaller: -37, larger: -27

Step-by-step explanation:

say one number is x the other one is y

x+y = -64

x-y = -10

subtract the two equations to get

2y = -54

y = -27

x = -37  

-27 is larger, -37 is smaller

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

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.
