The coordinates along the directed line segment is (-4, 5/3)
What is line segment ratio?This involves dividing a line into proportional ratios
How to find the coordinates of the point?The points are given as:
A = (-7, 2)
B = (2, 1)
The ratio on the segment can be represented as;
m : n = 1 : 2
So, we have the coordinates of the point that lies along the directed line segment to be
Point = 1/(m + n) * (mx₂ + nx₁, my₂ + ny₁)
So, we have:
Point = 1/(1 + 2) * (1 * 2 + 2 * -7, 1 * 1 + 2 * 2)
Evaluate
Point = 1/3 * (-12, 5)
Evaluate the products
Point = (-4, 5/3)
Hence, the coordinates of the point is (-4, 5/3)

Question: Carly is saving money babysitting on the weekends. last month, she saved $120. this month, carly saved 30% more than she saved last month. how much did she save this month?
Answer: Goodmorning: } It's $156.
Step-by-step explanation: you would change the 30% to a decimal by moving the decimal point two spaces to the right.
this would get you .30 or .3
you would then multiply the $120 by .3
you would get 36
then since she saved 30% MORE you would add the 36 to the 120 and get 156.

What is decimal number and division?
Decimal numbers are those numbers which consist of an integer part and a fractional part.
Decimal are of two types-
Terminating decimals are those decimals which has finite number of figures after decimal point
Non terminating decimals are those decimals which has infinite number of figures after decimal point.
Division is the process by which value of single unit can be calculated from the value of multiple unit
The number which is divided is the dividend, the number by which dividend is divided is the divisor, the result obtained is the quotient and the remaining part is the remainder.
There is a well known formula in division
Divisor x Quotient + Remainder = Dividend
Here,
Denominator of fraction = 9 = [tex]3^2[/tex]

Your friend
needs a trumpet for 1 year. She says she
should buy a trumpet because the cost
to rent one for 1 year is about the same
as the cost to buy one. Do you agree?
Explain.
Based on the cost to rent the trumpet, I agree that the trumpet's buying price is almost the same as the cost to rent the trumpet.
How to find the cost of the trumpet?The trumpet would cost about $575 to be bought if the friend decided to buy it outright.
If they decided to rent the trumpet however, the rental cost of the trumpet would be:
= Initial fee + (Monthly fee x Number of months in year)
The initial fee is $25 and the monthly fee is $45. The total cost to rent the trumpet in a year is:
= 25 + (45 x 12)
= 25 + 540
= $565
The cost of renting is $565 and this is close to the cost of buying which is $575.

You have 270 ft^2 of carpet. You want to install carpeting in a room that is 20 ft long and 15 ft wide. Do you have enough carpet? Explain how you know. (1pt)
Answer: No, there isn't enough carpet
Explanation:
The room is 20 feet by 15 feet. The floor area is length*width = 20*15 = 300 square feet, which is larger than the 270 sq ft of carpet you have available. Therefore, you don't have enough carpet. The amount needed is 300-270 = 30 sq ft
Answer:
No
Step-by-step explanation:
20 ft*15 ft=300 ft^2
you need to cover 300 ft^2
you only have 270 ft^2
so you can't cover it

Identify the correct equation of a line that passes through the points \displaystyle \left(-6,-10\right)(−6,−10) and \displaystyle \left(6,-2\right)(6,−2).
The equation of the line that passes through the points ( -6,-10 ) and ( 6,-2 ) is y = (2/3)x - 6.
How to determine the equation of a line from two points?The equation of line is expressed as;
y = mx + b
Where m is slope and b is the y-intercept.
Given the data in the question;
Point 1( -6,-10 )
x₁ = -6y₁ = -10Point 2( 6,-2 )
x₂ = 6y₂ = -2First, we determine the slope "m" of the line.
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
m = ( -2 - (-10) ) / ( 6 - (-6) )
m = ( -2 + 10 ) / ( 6 + 6 )
m = 8 / 12
Slope m = 2/3
Next, we determine the y-intercept "b"
y = mx + b
-10 = (2/3)(-6) + b
-10 = -12/3 + b
-10 = -4 + b
b = -10 + 4
b = -6
Now that the values of slope m and y-intercept b is known, plug these into y = mx + b to determine the equation of the line.
y = mx + b
y = (2/3)x + (-6)
y = (2/3)x - 6
Therefore, the equation of the line is y = (2/3)x - 6.

Matinee. Please write the system of equations.
(SHOULD BE 3 EQUATIONS)
Answer:
x= number of matinee tickets sold = 900
y= number of student tickets sold = 1800
z= number of regular tickets sold = 5800
steps below.
If this helped please mark my answer as the brainliest, thank you!
Answer:
System of equations:
[tex]\begin{cases}m + s + r = 8500\\5m + 6s + 8.5r = 64600\\s = 2m\end{cases}[/tex]
(where m is the number of Matinee tickets sold, s is the number of Student tickets sold and r is the number of Regular tickets sold).
Step-by-step explanation:
Given information:
Total tickets sold = 8,500Total proceeds = $64,600Cost of Matinee ticket = $5Cost of Student ticket = $6Cost of Regular ticket = $8.50Twice as many Student tickets were sold than Matinee tickets.Define the variables:
Let m = number of Matinee tickets sold.Let s = number of Student tickets sold.Let r = number of Regular tickets sold.Equation for the total tickets sold:
m + s + r = 8500Equation for the total proceeds:
5m + 6s + 8.5r = 64600Equation for twice as many Student tickets were sold than Matinee tickets:
s = 2mTherefore, the system of equations is:
[tex]\begin{cases}m + s + r = 8500\\5m + 6s + 8.5r = 64600\\s = 2m\end{cases}[/tex]
Solving the system of equations
To solve the found system of equations, substitute the third equation into the first equation and isolate r:
[tex]\implies m+2m+r=8500[/tex]
[tex]\implies 3m+r=8500[/tex]
[tex]\implies r=8500-3m[/tex]
Substitute the found expression for r and the third equation into the second equation and solve for m:
[tex]\implies 5m+6(2m)+8.5(8500-3m)=64600[/tex]
[tex]\implies 5m+12m+72250-25.5m=64600[/tex]
[tex]\implies 72250-8.5m=64600[/tex]
[tex]\implies 8.5m=7650[/tex]
[tex]\implies m=900[/tex]
Therefore, the total number of Matinee tickets sold was 900.
Substitute the found value of m into the third equation and solve for s:
[tex]\implies s=2(900)[/tex]
[tex]\implies s=1800[/tex]
Therefore, the total number of Student tickets sold was 1800.
Substitute the found value of m into the found equation for r and solve for r:
[tex]\implies r=8500-3(900)[/tex]
[tex]\implies r=8500-2700[/tex]
[tex]\implies r=5800[/tex]
Therefore, the total number of Regular tickets sold was 5800.

equation that is perpendicular to 5x +3y=-21 and passes through (-5,1)
The equation of line perpendicular to the line 5x + 3y = -21 will be;
⇒ y = 3x/5 + 4
What is Equation of line?
The equation of line with slope m and passes through the point
(x₁, y₁) is;
⇒ y - y₁ = m (x - x₁).
Given that;
The equation of perpendicular line is,
⇒ 5x + 3y = -21
And, The point on the line will be (-5 , 1)
Now,
The product of the slopes of the perpendicular line will be -1.
Slope of the perpendicular line 5x + 3y = -21 is;
5x + 3y = -21
y = - 5x/3 - 21/3
y = -5x/3 - 7
dy/dx = m₁ = -5/3
So, The slope of line which is perpendicular to the line is;
m₁ m₂ = -1
m₂ = -1/m₁
m₂ = 3/5
So, The equation of line perpendicular to the line 5x + 3y = -21 and passes through the point (-5, 1) is;
⇒ y - y₁ = m (x - x₁).
⇒ y - 1 = 3/5 (x - (-5)).
⇒ y - 1 = 3/5 (x + 5)
⇒ 5 (y - 1) = 3 (x + 5)
⇒ 5y - 5 = 3x + 15
⇒ 5y = 3x + 15 + 5
⇒ 5y = 3x + 20
⇒ y = 3x/5 + 4
Thus, The equation of line perpendicular to the line 5x + 3y = -21 will be;
⇒ y = 3x/5 + 4
