Answer:
2y - 3x = -15
Step-by-step explanation:
Slope of the line 4x + 6y = 1 is as shown below;
Rewrite in slope intercept form;
6y = -4x+1
y = -4x/6 + 1/6
y = -2x/3 + 1/6
mx = -2/3x
m = -2/3
The slope of the line perpendicular M = -1/(-2/3)
M = 3/2
Get the x and y intercept of 2x+3y = 18
x intercept occurs when y = 0
2x + 0 = 18
x= 18/2
x = 9
y intercept occurs when x = 0
0 + 3y = 18
3y= 18
y = 18/3
y = 6
The line passes through the point (9,6)
Write the equation in point slope form
y - y0 = m(x-x0)
y - 6 = 3/2(x-9)
2(y-6) = 3(x-9)
2y - 12 = 3x - 27
2y - 3x = -27 + 12
2y - 3x = -15
This gives the required equation
.Write an expression equivalent to -3 + 2/3y - 4 - 1/3y
Answer:
−7+y/3 is the same as that, but simplified.
Answer:
y/3-7
Step-by-step explanation:
The answer is the solved equation of -3+2/3y-4-1/3y.
Subtract 4 from -3 to get -7
= -7+2/3y-1/3y
Combine 2/3y and -1/3y to get 1/3y
-7+1/3, or just y/3-7.

Pam needs to save $905 per year for seven years to have enough for her first year with the help of her two grandfathers.
How Much Money Must Be Saved Every Year?Pam needs to save $903 each year to have enough for her first year of college tuition with the help of her two grandfathers.
To calculate this, we first need to add up the total amount of money Pam's two grandfathers are offering to contribute:
Grandfather 1: $6321
Grandfather 2: $6321
Total Contribution: $12642
We then subtract this total contribution from the total cost of tuition for the first year:
Tuition: $6321
Total Contribution: -$12642
Total Amount Needed: $6321
Finally, we divide this total amount needed by the number of years Pam has to save:
Total Amount Needed: $6321
Years: 7
Amount Needed to Save Each Year: $903

What is a zero measurement?
The quantity or complete absence of the thing being measured is represented by the zero point.
Ex. Because the zero point is set arbitrarily and does not indicate the complete absence of temperature, the Fahrenheit scale is an interval scale.
What exactly is a random zero point?Zero degrees on either scale is not a "true" zero because it is an arbitrary number. The absence of temperature does not occur at the zero point; It's just a random number on the scale. Other examples of common interval scales include: Age and SAT scores (one is culturally determined).
Which scale has a point at zero?In addition, on a ratio scale, the distance between two variables is also the same. Furthermore, a proportion scale has a genuine zero point, meaning the worth of zero isn't erratic.

Mrs.Vernon paid $72 interest for a 2-year loan at 9% annual interest. How much money did she borrow?
Vernon borrowed an amount of $400.
What is Interest Rate?Interest rate is the amount a borrower has to pay which is also a percentage of the principal amount, which is the amount loaned. Annual interest rate is this amount which the borrower has to pay once in an year.
Let the money Vernon borrowed = x
Annual interest rate = 9%
Interest paid for 1 year = x × 9%
Interest paid for 2 years = x × 9% × 2
Interest paid for 2 years is given as $72.
⇒ x × 9% × 2 = 72
x × 18% = 72
x × (18/100) = 72
0.18 x = 72
x = 72/0.18
x = 400
Hence the money Mrs. Vernon borrowed is $400

The median of 5,8,6,9,11,4 is 7.
The median is the middle point in a dataset—half of the data points are smaller than the median and half of the data points are larger.
Here we have to find the median of 5,8,6,9,11,4.
Arranging the given data/observations in ascending order:-
4, 5, 6, 8, 9, 11
Here we can see that there are 6 numbers given
so, n= 6
Where the number of terms is even.
We know that the formula to find the value of the median whose n value is given,
Median= {(n/2 +1 )th term +(n/2)th term} / 2
We can now substitute the value of n in the above formula, we get
Median= {(6/2+1) +(6/2)} / 2
We can now simplify the above step, we get
Median= 3rd observation + 4th observation / 2 = 6+8/2 = 7

what does it mean when a company's corporate spread tightens
A corporate (or credit) spread is the extra interest a lender demands to make up for the extra risk they take on by financing the business.
Companies borrow money from their investors through the use of bonds, which are debt instruments. Better performance and low-risk perceptions for businesses cause bond spreads to narrow. The corporate spread decreases when people have favorable and low-risk impressions about the company issuing the bond since it is the extra interest paid over the interest from US Treasury bonds.
A bond is an IOU that specifies the amount of reward the IOU holder will get upon repayment of the borrowed funds. Basis points are typically used to calculate this interest rate. The matching government bond yield is typically considered for determining spread. The spread decreases as the danger increases.
Basis points are a standard unit of measurement for the corporate spread. These are "hundredths of a percent" more than the interest rate on Treasury bonds. Accordingly, a spread of 100 basis points is equal to 1% more than the yield on government bonds.
Spreads that are getting tighter indicate a company's assessment of risk is getting better. This is because investors have enough faith in the business to invest in it in exchange for reduced spreads. Strong financial statements, improved loan servicing, or a generally stable market impression could all be to blame for this.

It reflects off the mirror and strikes a wall 9.5m away at point P. By what distance does the laser spot on the wall move if the mirror is rotated by 10??
As per the tangent formula, the distance does the laser spot on the wall move if the mirror is rotated by 10 is 2.9m
While we looking into the given question we have identified the following values,
Previous distance = 9.5
And the angle = 30 degrees
Rotated angle = 10 degrees
And the distance is considered as x.
Then as per the tangent formula, it can be written like the following,
=> tan 30/9.5 = tan 10/x
When we apply the tangent value, then we get,
=> 0.5773/9.5 = 0.1763/x
When we perform the cross multiplication, then we get,
=> 0.5773x = 9.5 x 0.1763
=> 0.5773x = 1.6749
Then the value of x is obtained as,
=> x = 1.6749/0.5773
=> x = 2.9012

A set has the closure property under a particular operation if the result of the operation is always an element in the set. If a set has the closure property under a particular operation then we say that the set is “closed under the operation.” The closure property of the division tells that the result of the division of two whole numbers is not always a whole number. Whole numbers are not closed under division that is a ÷ b is not always a whole number.
