It's B. Since the slope is -8/1 x. Slope is rise/run. The other answers doesn't make sense since the x is put in a different place.
Length of bridge = 53 meters
Length changes expected due to changes in temperature = expansion or contraction by 21 millimeters (or 0.021 meters)
Let length of bridge at any given time be 'a'
As an absolute value equation, the situation can be expressed as:
⇒ |a-53| < 0.021
Solving the equation
⇒ -0.021 < a-53 < 0.021
⇒ 53 - 0.021 < a < 53 + 0.021
⇒ 52.979 < a < 53.021
Hence, the minimum length of the bridge can be 52.979 meters and the maximum length of the bridge can be 53.021 meters.
Answer: x = r + s
Step-by-step explanation:
Try to get x to one side and everything else on the other side.
r = s - x ( add a to both sides)
r + s = s - s - x
r + s = x
Answer:
4n-1
Step-by-step explanation:
Diffrence bweetween each number, 3 and -1, -1 and -5, -5 and -9 is 4
4n
find the closest numbers
4*1=4
4*0=0
4*-1=-4
4*-2=-8
now we figure out how to make these numbers into our terms of this sequence
4n-1
4*1-1=3
4*0-1=-1
4*-1-1=-3
4*-2-1=-9
so the nth term is 4n-1
Answer:
Step-by-step explanation:
So we have the equation:
Subtract 7 from both sides:
Divide both sides by 3:
So, the value of w is 4.
And we're done!
