The equation of the line that is perpendicular with y = 4 · x - 3 and passes through the point (- 12, 7) is y = - (1 / 4) · x + 4.
How to derive the equation of a line
In this problem we find the case of a line that is perpendicular to another line and that passes through a given point. The equation of the line in slope-intercept form is described below:
y = m · x + b
Where:
m - Slopeb - Interceptx - Independent variable.y - Dependent variable.In accordance with analytical geometry, the relationship between the two slopes of the lines are:
m · m' = - 1
Where:
m - Slope of the first line.m' - Slope of the perpendicular line.If we know that m = 4 and (x, y) = (- 12, 7), then the equation of the perpendicular line is:
m' = - 1 / 4
b = 7 - (- 1 / 4) · (- 12)
b = 7 + (1 / 4) · (- 12)
b = 7 - 3
b = 4
And the equation of the line is y = - (1 / 4) · x + 4.

1. Abby baked 2-dozen brownies. She took 1 dozen to her scout meeting. Her family ate 8, and she put the rest in a container in the refrigerator. How can Abby find the number of brownies left in the refrigerator?
Answers
The number of brownies left in the refrigerator is 4.
How to calculate the value?It's important to note that 1 dozen = 12
In this case, Abby baked 2-dozen brownies, she took 1 dozen to her scout meeting and her family ate 8, and she put the rest in a container in the refrigerator.
Therefore, the remaining amount will be:
= 2 dozens - 1. dozen - 8
= (2 × 12) - 12 - 8
= 24 - 12 - 8
= 4
There'll be 4 left. This illustrates the concept of subtraction.

Downhill RacerA snowboardertravels 105 metersin 7 seconds.A skier travels for4 seconds andcovers 72 metersHow far will a skier travel in 2minutes? Explain how you figured it out.
Answers
To be able to determine the distance that the skier travels, let's first determine its constant rate (speed).
A skier travels for 4 seconds and covers 72 meters.
Constant Rate (Speed):
[tex]\text{ }\frac{\text{ Distance Traveled}}{\text{ Time}}\text{ = }\frac{\text{ 72 meters}}{\text{ 4 seconds}}\text{ = }18\text{ meters/second}[/tex]Determining the distance covered in 2 minutes:
Step 1: Convert the time in minutes into seconds.
[tex]\text{ 2 (minutes) x }\frac{\text{ 60 seconds}}{\text{ 1 (minute)}}\text{ = 2 x 60 seconds = 120 seconds}[/tex]Step 2: Multiply the time by the constant rate (speed) of the skier.
[tex]\text{ Distance Traveled = 120 (seconds) x }18\text{ }\frac{\text{ meters}}{\text{ (second)}}[/tex][tex]\text{ = 120 x 18 meters}[/tex][tex]\text{ Distance Traveled = 2,160 meters}[/tex]Therefore, in 2 minutes, the skier travels 2,160 meters.

We are asked to find the greatest common factor of the above numbers.
Note:
Greatest Common Factor means Highest Common Factor (HCF).

Use the multiplication method to solve the following systems of equations. c + 3t = 7 and 3c – 2t = –12
5x – 4z = 15 and –3x + 2z = 21
–4m + 3n = 50 and 2m + n = 10
2p – 4q = 18 and –3p + 5q = 22
3a + 4b = 51 and 2a + 3b = 37
Answers
After solving the system of equations we get the values as:
c=-2 and t=3x= -57 and z=-75m=-2 and n=14p=-89 and q=-49a=5 and b=9Given the equations are as follows, we need to solve them using multiplication method:
c+3t=7 and 3c-2t=-12take c+3t=7
rearrange the terms.
c = 7-3t
substitute c value in other equation.
3(7-3t)-2t=-12
21-9t-2t=-12
21-11t=-12
-11t = -12-21
-11t=-33
t=33/11
t=3
now substitute t value in c = 7-3t
c = 7-3(3)
c=7-9
c=-2
hence t and c values are 3 and -2.
5x – 4z = 15 and –3x + 2z = 21take 5x – 4z = 15
5x = 15+4z
x=15+4z/5
substitute x value in other equation.
-3(15+4z/5)+2z=21
-45-12z+10z=105
-45-2z=105
-2z=105+45
z=-75
substitute z value in x=15+4z/5
x=15+4(-75)/5
x=-57
hence x and z values are -57 and -75.
–4m + 3n = 50 and 2m + n = 10consider, -4m+3n=50
3n = 50+4m
n=50+4m/3
substitute n value in other equation.
2m+n=10
2m+50+4m/3 = 10
6m+50+4m=30
10m=30-50
10m=-20
m=-2
substitute m value in n=50+4m/3
n = 50+4(-2)/3
n = 50-8/3
n = 42/3
n = 14
hence m and n values are -2 and 14.
2p – 4q = 18 and –3p + 5q = 22consider 2p - 4q = 18
2p = 18+4q
p = 9+2q
substitute p value in other equation.
-3p+5q=22
-3(9+2q)+5q=22
-27-6q+5q=22
-27-q=22
-q = 22+27
q = -49
now p = 9+2q
p = 9+2(-49)
p = 9-98
p=-89
hence p and q values are -89 and -49.
3a + 4b = 51 and 2a + 3b = 37consider 3a + 4b = 51
3a = 51-4b
a=51-4b/3
substitute a value in other equation.
2(51-4b/3)+3b=37
102-8b+9b=111
102+b=111
b=111-102
b=9
now, a=51-4(9)/3
a = 51-36/3
a = 15/3
a = 5
hence a and b value are 5 and 9.

The question is about scaling a map, the scale is 2miles is represented by 5 inches. This information is used to calculate the actual length when a measure of 7 1/2 inch is taken from the drawing

How to find the amount Mr Kepler paid for the tool, not including taxGiven that:
with a discount of 40% off the regular price
The regular price was $200
A discount of 40% is given to Mr Kepler. Discount represents amount less the total amount. At a 40% discount Mr Kepler paid 60%
40% = 0.4
40% discount = 1 - 0.4 = 0.6 (equivalent to 60%)
The amount Kepler paid

Knowledge of percentage is used here and the amount Mr Kepler paid is $120 not including tax
34% of 850
The statement 34% of 850 means 34 divided by 100 multiplied by 850. The division by hundred takes care of the percent, then "of" means multiplication
34% = 0.34
0.34 * 850 = 289

what percentage of students scored before 70-90 points on the exam? Round your answer to the nearest tenth of a percent?
Answers
We want to find the percentage of students that scored between 70-90 points on the examn. Also, we know that there are a total of 71 students, so we have to count the number of students who got between 70-90 points.
We see them represented on the histogram as the two largest bars, and we obtain:
[tex]\begin{gathered} 21\text{ students scored between 70-80 points} \\ 22\text{ students scored between 80-90 points} \end{gathered}[/tex]So, the total of students that scored between 70-90 points is 21+22=43.
For finding the percentage, we make the quotient between the number of students with a score of 70-90 and the total of the students in the class.
[tex]=\frac{43}{71}\cdot100=60.6[/tex]This means that approximately a 60.6% of the class students scored between 70 and 90 points.

Sparkles the Clown makes balloon animals for children at birthday parties. At Bridget's party, she made 5 balloon poodles and 1 balloon giraffe, which used a total of 15 balloons. For Eduardo's party, she used 7 balloons to make 1 balloon poodle and 1 balloon giraffe. How many balloons does each animal require?

Let p be the number of balloons required to make one balloon poodle and g the number of balloons required to make one balloon giraffe.
Then we have:
I) 5p + g = 15
II) p + g = 7
Subtracting equation II from equation I, we have:
5p - p + g - g = 15 - 7
4p = 8
p = 8/4
p = 2
Replacing p with 2 in equation II we have:
2 + g = 7
g = 7 - 2
g = 5

Find the coordinates of the other endpoint of the segment, given its midpoint and one endpointand y.)midpoint (-7.-21), endpoint (-13.-15)
Answers
Ok, we are going to use the midpoint formula
M = ( (x1 + x2) / 2 , (y1 + y2) / 2 )
(-7,-21)=((x1-13)/2 , (y1-15)/2 )
Break up this formula into two equations.
(x1-13)/2=-7 and (y1-15)/2=-21
Solve for x1 and y1 from the equations. So:
x1=(-7*2)+13
x1=(-14)+13=-1
y1=(-21*2)+15=(-42)+15=-27
So the other endpoint is (-1, -27).
