Answer:
Equation of the line is y = -x + 4
Step-by-step explanation:
When the two lines having their slopes 
and 
are perpendicular to each other then 
If is the slope of the line passing through two points (0, 3) and (4, 7) then
= 
= 1
Now slope of the second line perpendicular to first line will be
= 
= -1
Slope intercept form of the equation of a line is represented by
y = mx + c
where m = slope
c = y intercept
Since the line is passing through (-1, 3) and slope = -1, therefore,
3 = -1 + c
c = 4
Now we plug in these values in the equation.
y = -x + 4
Equation of the line is y = -x + 4
30 x 60
Step-by-step explanation:
the length of the perimeter would be 180, subtract 60ft for the fencing replaced by the wall and you meet the maximum 120ft
30X60 gives you the largest area with 1800ft^2
Answer:
least to greatest: -16/32, -8/20, 3/5
Step-by-step explanation:
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.
He should spend at least $4.00 on each 4.00/22
