Answer:
Step-by-step explanation:
If you're asking for the equation of a line that goes through (1,-5) and is perpendicular to y=18x+26 here's what you do.
1. find the slope of the new line by taking the negative reciprocal of the slope of the first line (
)
2. plug in the point (1,-5) and the new slope into the point slope form equation
3.Now that you have y-(-5)= -1/18(x-1) simplify
3.a y-(-5)= -1/18x + 1/18
3.b y=-1/18x - 89/18
4. final equation you get is y = -1/18 - 89/18
Step-by-step explanation:
the general slope intercept form is
y = ax + b
a is the slope, b is the y-intercept (when x=0).
1.
is already defined
y = -2x + 6
2.
the slope is expressed as ratio y/x indicating how many units y changes, when x changes a certain amount of units when going from one point to another.
(-3, -5) and (2, 5).
x changes by +5 units (from -3 to 2), y changes by +10 units (from -5 to +5).
so, the slope is 10/5 = 2
that gives us the first part of the equation :
y = 2x + b
we get b by using the coordinates of one of the points as x and y. e.g. (2, 5)
5 = 2×2 + b = 4 + b
1 = b
so, the full line equation is
y = 2x + 1
It would equal 8 because 2 times 2 equals 4, than 4 times 2 equals 8. Hope this helps!
Answer:
200 packages
Step-by-step explanation:
change 6 m to cm
100 cm = 1 m
6m * 100 cm/1m = 600 cm
we have 600 cm
take 600 cm and divide by 3 cm to close each package
600 cm /3 cm = 200 packages
