6x + 2x = 8x
so 8x is the right answer
Answer:
26
Step-by-step explanation:
isosceles traingle:
AB=BC
7x-13=x+29
x=7
AC= 3x+5
AC= 3(7)+5
AC= 26
improper you need to simplify which would become 2 and 2/3
2. y=2x+3
When x =0 and y= something, the 'something' is your y-intercept which is b in the y=mx+b formula. Then we look at what is changed in the x and y value to determine the m part. the x increase by 1 and y increase by 2 so the m part is 2.
3. y=-7x
Same as the last one, there is no y-inter this time because the y=0 when x=0/ So the y deceased by 7 each time and x incease by 1 so it is -7 for the m part.
