The equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2
What is the Point-slope form?The equation of the straight line has its slope and given point.
If we have a non-vertical line that passes through any point(x1, y1) and has a gradient m. then general point (x, y) must satisfy the equation
y-y₁ = m(x-x₁)
This is the required equation of a line in a point-slope form.
We know that Point-Slope Form:
y - y₁ = m(x- x₁)
Where x₁ - x coordinate and y₁ - y coordinate
m - slope
Point (8,-4)
Then Slope m = 1/2
Now the equation as;
y + 4 = 1/2(x - 8)
y = -1/2(x -4) - 4
y = -x/2 + 2 - 4
y = -x/2 - 2
Hence, the equation of the line that passes through the point (8,-4) and has a slope of 1/2 is; y = -x/2 - 2

An equation of a line perpendicular to the line represented by the equation y = -
1/2 x - 5 and passing through (6,4) is what?
Answer:
y= 1/2x+1
Step-by-step explanation:
Answer:
[tex]y=2x-8[/tex]
Step-by-step explanation:
First, remember that perpendicular lines have opposite and reciprocal slopes to the original line. That means for this line, your slope will be 2 (flip the fraction and change the sign). So we have:
[tex]y=2x+b[/tex]
Next, plug in the point that it passes through in order to find the y-intercept (b).
[tex]4=2(6)+b[/tex]
[tex]4=12+b[/tex]
[tex]b=-8[/tex]
So your equation will be:
[tex]y=2x-8[/tex]

Hey, I don´t understand the graphing part of inequalities.
Answer:
See explaination
Step-by-step explanation:
While graphing inequalities, think of the inequality sign as an equal sign.
So, y=mx+b.
Say the inequality was y>3x+7, I would think fo the > as an equal sign.
So, in your head, "write" it like this: y=3x+7. Hope this helps.

Franklin school is having a Popsicle party for its nine hundred fifty four students.The secretary there will some Popsicle left over to share with the teachers. Each student will get two Popsicle. Popsicle come in boxes that have one dozen Popsicle. There are twenty-five boxes in cartoon, how many boxes of Popsicle? Show your work.
Answer:
175 boxes
Step-by-step explanation:
There are a total of 954 students since each student will get two popsicles that would mean we need a total of 1,908 popsicles (954 * 2). Since each box contains 12 popsicles then we simply divide the total number of popsicles needed by the number of popsicles that fit in each box to find the total number of boxes.
1,908 / 12 = 159 boxes
Since there are 25 boxes per carton we divide 159 by 25
159 / 25 = 6.36
Now we see that we need at least 6.36 cartons of popsicles, but since we can't get 6.36 we would need to get 7 cartons which would bring a total of
7 * 25 = 175 boxes
Finally, we would end up with 175 boxes of popsicles which would be enough for all the students and have leftover for the teachers.
6. If m∠COD=8x+13, m∠BOC=3x-10, and m∠BOD=12x-6, find m∠BOD
Answer:
Step-by-step explanation:
Given
m∠COD=8x+13,
m∠BOC=3x-10, and
m∠BOD=12x-6
The following addition property is true;
<BOD = <BOC + <COD
Substitute
12x-6 = 3x-10+8x+13
12x-6 = 11x+3
12x-11x = 3+6
x = 9
Get <BOD
<BOD = 12x-6
<BOD = 12(9)-6
<BOD = 108-6
<BOD = 102°
A group of ‘n' friends decided to rent a condominium for a one week vacation in Florida. They decided to share the weekly rent of ‘m' dollars equally. If due to an unanticipated reason two members of the group couldn't make the trip, and the rest of the friends decided not to charge the two who pulled out for the rent; what will be the additional amount each of the remaining friends must pay for renting the condominium?
Answer:
2m / n² - 2n
Step-by-step explanation:
Given that:
Number of friends = n
Weekly rent = $m
To share rent fee equally :
Each friend will pay : $m / n
If 2 of the friend couldn't make the trip:
Additional amount to be shared by the others = 2(m/n) = 2m/n
Hence additional fee per friend who eventually made the trip:
Additional amount to be shared / number of friend who eventually made the trip
= (2m/n) ÷ (n - 2)
= 2m / n * 1 / n - 2
= 2m / n(n-2)
= 2m / n² - 2n

When dividing each of the numbers $$3759$$ and $$4139$$ by some positive integer number, the remainder happened to be equal to $$16$$. What is the smallest possible value of the divisor?
Answer:
The smallest possible value of the divisor is 19
Step-by-step explanation:
The given numbers for division are;
3759 and 4139, the remainder = 16
Let x represent the number
Therefore, we have;
x > 16
x is a factor of 3759 - 16 = 3743, and x is also a factor of 4139 - 16 = 4123
The factors of 3743 obtained from an online resource are 1, 19, 197, 3759
The factors of 4123 obtained from an online resource are 1, 7, 19, 31, 133, 217, 589, 4123
The common factors of 3743 and 4123 are 1, 19
Given that x > 16, we have, x = 19
Therefore, the smallest possible value that will divide both 3759 and 4139 whereby the remainder is 16 = 19

Answer:
100°
Step-by-step explanation:
first you need to find the other angle. to do so do 180-135=45
so you know 2 angles now. 35° and 45°. Add these angles (you get 80°)
then 180-80=100
Select the correct answer. Which statement is true about this equation? -9(x + 3) + 12 = -3(2x + 5) − 3x A. The equation has one solution, x = 1. B. The equation has one solution, x = 0. C. The equation has no solution. D. The equation has infinitely many solutions.
Answer:
its D
Step-by-step explanation:
-9(x + 3) + 12 = -3(2x + 5) − 3x
-9x-27+25 = -6x-15-3x
-9x-15 = -9x - 15
same on both sides
so x has infinitely many solutions
The equation has no solutions. Option C is correct.
To figure out which statement is true for equation -9(x + 3) + 12 = -3(2x + 5) − 3x.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
-9(x + 3) + 12 = -3(2x + 5) − 3x.
Simplification,
LHS
= -9(x + 3) + 12
= -9x -21 + 12
= -9x -9
RHS,
= -3(2x + 5) − 3x
= -6x - 15 - 3x
= -9x - 15
Equation RHS and LHS,
-9x - 15 = -9x -9
-15 = -9
Implies, the value of x terminate means the given expression has no solution,
Thus, the equation has no solutions. Option C is correct.
