Answer: 27, 28 and 29
Step-by-step explanation:
Since the panels take three consecutive numbers of bolts to attach to the wall, let the numbers be y, y+1 and y+2.
y+y+1+y+2 = 84
3y+3=84
3y = 84 - 3
3y = 81
y = 27
Therefore, the bolts are 27, 28 and 29 respectively
Answer:
y = -1/2x - 2
Step-by-step explanation:
If it's parallel, that means that the slope is the opposite of the one in the given equation, meaning that 2 would be flipped and turned negative into -1/2.
Then, fill in the x and y values to get the y-intercept.
1 = -1/2(-6) + b
1 = 3 + b
-2 = b
So your answer is y = -1/2x - 2
Answer:
x = 4
Step-by-step explanation:
Given
- 8 - x = x - 4x, that is
- 8 - x = - 3x ( add 3x to both sides )
- 8 + 2x = 0 ( add 8 to both sides )
2x = 8 ( divide both sides by 2 )
x = 4
Answer:
x=0, x=5
Step-by-step explanation:
x²-5x+8=8
x²-5x=0
x(x-5)=0
x=0 , x-5=0
x=5
