Interms 10. The sum of a certain number and a second number is -42. The first
number minus the second number is 52. Find the numbers.
56​

the first number and the second number is 5 and -47 respectively

Step-by-step explanation:

Let us assume the first number be x

And, the second number be y

According to the question

x + y = -42

x - y = 52

x = 52 + y

Now put the value of x in the first equation  i.e.

x + y = -42

52 + y + y = -42

2y = -42 - 52

2y = -94

y = -47

And, x is

x + y = -42

x -47 = -42

x = 5

Hence, the first number and the second number is 5 and -47 respectively

the answer is c

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
