2/3h−1/3h+11=8
1/3h = -3
h = -3(3)
h = - 9
x-10=x/2
Simplify both sides of the equation.
x−10 = x
/2
x+-10 = 1/2 x
x-10 = 1/2 x
Subtract 1/2 x from both sides.
x-10-1/2 x = 1/2 x - 1/2 x
1/2 x-10 = 0
Add 10 to both sides.
1/2 x-10+10 = 0+10
1/2 x = 10
Multiply both sides by 2.
2*(1/2 x) = (2)*(10)
Your answer should be: x = 20
Find the opposite of adding 15. So it would be subtracting 15. So subtract 15 on both sides. So it would have 2/3x on the left and then 2 on the other side. (2/3x=2) Now find the opposite of multiplying 2/3. It is dividing 23/3. So divide 23/3 on both sides. So multiply 2/3 times 1/2. It would equal 3. x = 3
Hope this helps. :-)
Answer:
The correct answer is A. -1
Step-by-step explanation:
The y-intercept is simply the name of the point where the line passes through the y-axis. Since you already stated that that point comes at -1, we know the intercept is -1.
AC = 2 (MN)
AC = 2 (9)
AC = 18
