EXPLANATION
When x=6 and y=13 x+y = 6 + 13 = 19
x + y = 19
I think that is the first one
Answer:
im not quite sure sorry
Step-by-step explanation:
Let's break it down quick
since (8*5) is in parenthesis, you have to do it first which would equal 40. 10*2=20*8 is 160. Since there is a negative in between that and 3*40 you must solve 3*40 first, which equals 120. Now,
160-120= 40
The answer to the question is 40.
1. y= 1,3,5,7,9
2. y= -1, -8, -5, -2, 1
5. y= -3, -2, -1, 1
method:- just substitute the value of X into the equation given in each question.
example:- if x=2 and given equation is y=2x + 3 find y. so y= 2(2)+3= 7
