Answer:
'Substitute the slope and the coordinates of point P(-3,2) in y = mx + b and then solve for b in each equation'.
Step-by-step explanation:
Kiana wants to write equations in the form y = mx + b for the lines passing through point P that are parallel and perpendicular to line q.
This equation is in the slope-intercept form where m is the slope and b is the y-intercept.
First, she finds the slope of line q and the slope of line s to be – 2. Point P is located at (-3,2).
Therefore, the step that can be used to find the y-intercept is 'substitute the slope and the coordinates of point P(-3,2) in y = mx + b and then solve for b in each equation'. (Answer)
It’s the first one ( quadratic )
Answer: 2.2 meters
Step-by-step explanation:
The data is:
The initial piece is 6.35 meters long.
We cut 25 pieces of 16.2cm each, so in pieces only we have:
25*16.2cm = 405cm
1m = 100cm
Then: 405cm = (405/100) m = 4.05m
And each time that we cut a piece, we have 4mm of waste.
Then we have 25 times the 4mm of waste, this means that the total waste is:
4mm*25 = 100mm
and 1000mm = 1m
100mm = (100/1000) m = 0.1m
So the total amount that was cut is:
4.05m + 0.1m = 4.15m
The length in the channel iron will be: 6.35m - 4.15m = 2.2 meters
