Let the amount Nick gets = x
Angad gets 3x ( 3 times as much as Nick)
Peter gets 6x (Twice as much as Angad)
Add together to equal the total amount:
x + 3x + 6x = 200
Simplify:
10x = 200
Divide both sides by 10:
x = 20
Angad gets 3x = 3(20) = 60

What is the equation of a line that is parallel to y=4 that passes through (1, -5)
Answer:
y = - 5
Step-by-step explanation:
y = 4 is a horizontal line parallel to the x- axis
A parallel line must therefore be a horizontal line with equation
y = c
where c is the value of the y- coordinates the line passes through.
The line passes through (1, - 5) with y- coordinate - 5, thus
y = - 5 ← equation of parallel line
The average profit/loss of a company (in thousands of dollars) was documented for 30 months. The 5th month showed a loss of $3000, however the 25th month
showed a profit of $5000. Assuming the profitloss is linear, write the equation of the line, in slope-intercept form, that represents the profit/loss for each month x. Use
this result to predict the profit/loss after 60 months
Hint: Use the ordered pairs (5. - 3) and (25,5).

The equation of the line in slope-intercept form is y= 5x -5.
(Type an equation using x and y as the variable. Type your answer in slope-intercept form. Use integers or fractions for any numbers in the equation.)

Gina Wilson All Things Algebra Unit 3 Parallel and Perpendicular Lines
Answer:
Parallel lines are lines that do not meet while perpendicular lines are aligned 90 degrees to each other.
Step-by-step explanation:
Imagine two straight lines, drawn side by side to each other with no angle between them. When they are drawn to infinite, no point of one line would touch the other.
Perpendicular lines are two or more line that meets at a point to form a right angle, that is, separated with an angle of 90 degrees to each other.

She charges her customers a call out fee of £35, plus £30 per hour.
How much should a customer be charged for wiring a house with 10 lightswitch?
Answer:
£395.
Step-by-step explanation:
Call out fee=35
30 per hour = 2 hour to be =60
but,12 minutes in hours= 12/60= 0.2
0.2 = 0.2*30 = 6
2 hours and 12 minutes would be charge as
30 + 6 = 36
36*10 = 360
call out fee + per hour = 35 + 360 + 395

A random sample of online music video views and number of guitar sales was measured, and the computer output for regression was obtained: Coefficients Standard Error t Stat P-value Intercept 7.856710924 1.316226455 5.969118 0.001889 Music Video Views 0.094781123 0.027926367 3.393965 0.019378 R-sq. = 69.73%R-sq. (adj) = 63.68% Part A: Use the computer output to determine the LSRL. Identify all the variables used in the equation. Part B: What proportion of the variation of guitar sales is explained by its linear relationship to music video views? Explain. Part C: Determine if increased guitar sales were caused by online music video views. Explain your reasoning.
Answer:
Explained below.
Step-by-step explanation:
The regression analysis output is as follows:
Coefficients Standard Error t Stat P-value
Intercept 7.856710924 1.316226455 5.969118 0.001889
Music Video 0.094781123 0.027926367 3.393965 0.019378
Views
R-sq. = 69.73%
R-sq. (adj) = 63.68%
A
There are two variables used in this study, the independent and the dependent variable.
The independent variable is the number of online music video views and the dependent variable is the number of guitar sales.
B
The coefficient of determination R² specifies the percentage of the variation in the dependent variable (Y) that is forecasted or explained by linear regression and the forecaster variable (X, also recognized as the independent-variable).
Thus, the proportion of the variation of guitar sales that is explained by its linear relationship to music video views is 69.73%.
C
The least square regression line is:
[tex]y=7.856710924+0.094781123\cdot x[/tex]
The least square regression line implies that there is a positive relationship between the guitar sales and music video views. That is as the number of music video views increases the guitar sales increases. And vice-versa.
Thus, increased guitar sales were caused by online music video views.
The functions f(x) and g(x) are described below.
f(x) = 7x + 9
g(x) = 7x - 4
The graph of g(x) is obtained by shifting down the graph of f(x) by _____ units.
Answer:
13 units
Step-by-step explanation:
Because the c term (9 for f(x)) represents the y intercept. The y only moves the graph up or down. Since we are trying to get from 9 to -4 move down by 13 units.

What is Equation of line?The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is,
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (- 1, 0) and (0, 1).
Now,
Since, The equation of line passes through the points (- 1, 0) and (0, 1).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (1 - 0) / (0 - (-1))
m = 1 / 1
m = 1
Thus, The slope of the line in the graph is,
⇒ m = 1

Find the coordinates of the point 7/10 of the way from A (-3,-5) to B (9.4)
Answer:
(-2/17, 5/17)
Step-by-step explanation:
Given the coordinates A (-3,-5) to B (9,4), we are to find the coordinate of the point cutting the line using the ratio 7:10
Using the midpoint formula;
M(X,Y) = {(ax1+bx2/a+b, (ay1+by2/a+b))
Given
x1 = -3, y1 = -5, x2 = 9, y2 = 4, a = 7 and b = 10
get the required coordinates;
X = ax1+bx2/a+b
X = 7(-3)+10(9)/7+10
X = -21+19/17
X = -2/17
Get the Y coordinate;
Y = ay1+by2/a+b
Y = 7(-5)+10(4)/7+10
Y = -35+40/17
Y = 5/17
Hence the required coordinate is (-2/17, 5/17)
1. Sally decided to go early Christmas shopping at a local Wal-Mart. There was
a Black Friday sale and she bought a TV that was originally $200. The TV
was marked down 25%. How much did Sally pay after it was marked down?
(1 point)
Answer:
150$
Step-by-step explanation:
In order to find the answer to this question you must find twenty-five percent of two-hundred.
50% of 100 = 50
100% of 100 = 100
100% of 200 = 200
50% of 200 = 100
25% of 200 = 150
= 150$

which line is perpendicular to y=2x+4?
a. y=2x-6
b. y=-1/2x+7
c. y=-1/4x+2
d. y=-4x+3
Answer:
B
In the equation y=mx+b m is the slope of the line.
Therefore the coefficient in each of these equations is the slope.
A line with a perpendicular slope must have the inverse opposite of the actual line. For example if a line has a slope of 5, a perpendicular line to that line must have a slope of -1/5. If a line has a slope of 10, the perpendicular line has a slope of -1/10. If a line has a slope of 2 then the inverse opposite is -1/2 and that is the slope of the perpendicular line.
B is the only answer with the correct slope so B is the answer.

First do 3 divided by 3/4 and that gives you 4. Then multiply 4 by 12 and you get 48.
Answer:
45
Step-by-step explanation:
I love math, so this was fun! First, we need to know how long it would take him to walk 1 mile. We know it took 12 minutes to walk 3/4 of a mile, so we just need to figure out how long each quater is. For this problem, each quarter of a mile is 3 minutes, and so we just need to multiply that by 4. then, we know it would take him 15 mintues to walk a mile. Then, just multiply that by 3!
