PLEASE HELP!!! Write the equation of a line that goes through the point (6, 3) and is perpendicular to the line y = 4x + 1.
Tpy6a [65]

For this case we have that by definition, the equation of a line in the point-slope form is given by:

y-y_ {0} = m (x-x_ {0})

Where:

m: It is the slope of the line and (x_ {0}, y_ {0})is a point through which the line passes.

We have the following equation of the slope-intersection form:

y = 4x + 1

Where the slope is m = 4

By definition, if two lines are perpendicular then the product of their slopes is -1.

Thus, a perpendicular line will have a slope:

m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {4}\\m_ {2} = - \frac {1} {4}

Thus, the equation will be of the form:

y-y_ {0} = - \frac {1} {4} (x-x_ {0})

Finally we substitute the given point and we have:

y-3 = - \frac {1} {4} (x-6)

Option B

A bag of chips weighs 228 grams. If each chip weighs 0.12 grams, how many chips are in the bag?
Gala2k [10]

Answer:

1900

Step-by-step explanation:

so lets let x represent the total chips that in the bag.

We know that each chip weight 0.12 grams, and there are 228 grams in total.  ok so, 0.12x=228

Divided 0.12 to each side

0.12x/0.12=228/0.12

x=1900 chips Which  means there are 1900 chips in the bag. I hope this helped you<3 sorry if it didnt:(
