someone help i’ll mark brainliest!!! Find the equation of the line through (7,1)
that has a slope of 1/2
Express your answer in General (Standard) Form.
Answer:
y=1/2x - 2.5
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can use the point-slope formula to write an equation for this line. The point-slope formula states :
where m is the slope and (x1 y1) is a point the line passes through .
We can substitute the slope and values from the point to give:
(y-1) = 8 (x-7)
We can also transform this equation to the slope-intercept form by solving for
y
. The slope-intercept form of a linear equation is: y=mx+b
where the m is the slope and b s the y-intercept value.
y-1= (8 times x) - ( 8 times 7)
y-1= 8x - 56
y-1 + 1= 8x- 56 + 1
y-0= 8x- 55
y= 8x - 55

considering the line negative x -6 y equals -6 what is the line perpendicular with a slope of a line perpendicular to this line what is the slope of the line parallel to this line
9514 1404 393
Answer:
perpendicular: undefined
parallel: zero
Step-by-step explanation:
The line y = -6 is a horizontal line. Between any two points on the line, the difference in y-values is zero, and the difference in x-values is non-zero. The slope of this horizontal line is the ratio of these differences:
slope = 0/(non-zero) = 0
Any parallel line will have the same slope. The slope of a parallel line is 0.
__
A line perpendicular to a horizontal line is a vertical line. It will have the equation x = constant. Between any two points on the line, the difference in y-values is non-zero, and the difference in x-values is zero. The slope of this vertical line is the ratio of these differences:
slope = (non-zero)/0 = undefined
The slope of the perpendicular line is undefined.

Unicorns love eating jelly beans! If a unicorn eats 410.7 ounces of jelly beans 6 times a day, how many ounces does it eat in one day?
Answer:
2464.2
Step-by-step explanation:
you multiply 410.7 by 6 to get this
The ounces of jellybean eaten in a day is required.
The amount of jellybean the unicorns eats in one day will be 2464.2 ounces.
The ounces of jellybean eaten at one time is 410.7 ounces
The number of times jellybean is eaten during one day is 6 times.
[tex]1\ \text{time}=410.7\ \text{ounces}[/tex]
So, for 6 times

What is the slope of the line that is perpendicular to the line that passes through the points (-1,3) and (2,-4)?

Find the slope from the 2 points.
(-12,-9) and ( 18, 6)
-2
-1/2
2
1/2
Step-by-step explanation:
the slope of a line is the ratio y/x.
that means when going from one point to the other, how many units is y changing, when x changes a certain number of units.
so, going from one point to the other here, x changes by 30 units (from -12 to +18). and y changes 15 units (from -9 to 6).
therefore, the slope is
15/30 = 1/2

IGNORE THE BOTTOM ONE PLEASE HELP
Answer:
see explanation
Step-by-step explanation:
∠ A and ∠ FCE are corresponding angles and are congruent , then
∠ A = 150°
∠ FCE and ∠ C are vertically opposite angles and are congruent , then
∠ C = 150°
∠ FCE and ∠ ECB are adjacent angles on a straight line and sum to 180°
∠ ECB = 180° - ∠FCE = 180° - 150° = 30°
∠ E = 180° - (30 + 45)° ← sum of angles in a triangle
∠ E = 180° - 75° = 105°
∠ CBE and ∠ D are same- side interior angles and sum to 180° , then
∠ D = 180° - 45° = 135°

i need step by step explanition if you can. paper depot is delivering 952 cases of paper today.300 of the cases are plain white paper twenty-eight trucks are being loaded with an equal number of cases of paper. how many cases will each truck carry
Answer:
34
Step-by-step explanation:
We actually don't care what amount of paper is white, we just need the amount per truck. If there were 2 trucks, they would each take half of the total amount of paper. If there were 3 trucks, they would each take a third of the total amount of paper. And so on for 4,5,6,etc.
For 28 trucks, they would each take a twenty-eighth of the total amount of paper. So, the amount each truck takes is just [tex]952/28=34[/tex].
So, the answer is [tex]\boxed{34}[/tex] and we're done!
