Answer:
I DONT KNOW WHAT YOU ARE ASKING
Step-by-step explanation:
Answer:
x=1
Step-by-step explanation:
(7x-1)+(2x-1)=7
7x+2x-1-1=7
7x+2x=7+1+1
9x=9
9x/9 = 9/9
x=1
Answer:
312
Step-by-step explanation:
you do 10 times 5 and then u get 6(50 + 2) and then distribute the 6 and then you get 300 + 12 and then it's 312 is ur answer
Answer:
The slope is 5/2 and the y intercept is -1
Step-by-step explanation:
To find the slope and the y intercept, we will write the equation in slope intercept form, y =mx+b where m is the slope and b is the y intercept
5x -2y =2
Add 2y to each side
5x-2y+2y =2 +2y
5x = 2+2y
Subtract 2 from each side
5x-2 = 2y+2-2
5x-2 =2y
Divide each side by 2
5x/2 -2/2 = 2y/2
5/2x -1 = y
y = 5/2x -1
The slope is 5/2 and the y intercept is -1
Answer:
(-2, 0)
Step-by-step explanation:
Use elimination: add the two systems. Because the left is equal to right, you are adding the same thing and it's legal.
-x+3y=2
+ (x+y=-2)
Add each term
-x+x + 3y+y = 2+ -2
4y=0
y=0
x+y=-2
x+0=-2
x=-2
