Answer:
4. -1/2 and 2
5. N and R
Step-by-step explanation:
Well if you want me too do 5 I’ll do 4 too.
So for #4 it’s actually pretty simple we just have to seperate y that’s it.
So first we have to get y by itself by subtracting 3x to the other side so the equation looks like this now
.
Now we have to take away the 6 and to do that we divide it to all the numbers and variables. Which gets us
.
So m and b are -1/2 and 2.
So we have to graph y = -1/2x + 2 so look at the image below.
So looking at the image we can see it passes through the points N and R.
Answer:
(6 , 3)
Step-by-step explanation:
Given
x + 3y =15 ------- equation 1
4x + 2y = 30 --------- equation 2
x = 15 - 3y
Put value of x in equation 2
4 (15 - 3y) + 2y = 30
60 - 12y + 2y = 30
-10y = -30
divide by '-10' on both sides
y = 3
now, put value of y in equation 1
x + 3(3) = 15
x + 9 = 15
x = 15 - 9
x = 6
So , (x , y) = (6 , 3)
12x-3y=21
4x-y=7
I hope this helps
1 = A 2= H 4= J 5= D
i don't know the answer to 3 though sorry
hope this helps if u have any questions let me know and also if u could mark this as brainliest i would really appreciate it!
