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.

❗ The way I solved this problem doesn't involve me using point-slope form like the problem tells you to use❗

⭐ Perpendicular lines have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to

⭐What does "opposite reciprocal" mean?

⭐What is slope-intercept form?

We can find the equation of the perpendicular line by:

1. Substituting the slope into the point-slope form equation:

⭐ Perpendicular lines have a slope that is the opposite reciprocal of the slope of the line it is perpendicular to

The slope of the line the perpendicular like is perpendicular to is [tex]\frac{-1}{2}[/tex].

Therefore, the slope of the perpendicular line is [tex]2[/tex]

Substitute the slope into the point-slope form equation.

[tex]y = 2x + b[/tex]

Now, all we have to do is solve for b.

2. Substituting the given coordinate into the point-slope form equation:

We are given the coordinate (6,9).

[tex]y = 2x + b[/tex]

[tex]9 = 2(6) + b[/tex]

[tex]9 = 12 + b[/tex][tex]-3 = b[/tex]

Substitute "b" into the point-slope form equation.

[tex]y = 2x + 3[/tex]

Answer:

g(x) = f(x) + 4 → Graph #5

h(x) = f(x + 4) → Graph #6

k(x) = f(x) - 4 → Graph #4

m(x) = f(x - 4) → Graph #3

Step-by-step explanation:

g(x) = f(x) + 4 → Graph #5

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the y-values of f(x) up by 4.

⭐ Graph #5 exhibits this transformation because I took the point (0,1) and shifted it up 4 units to get (0,5). Graph #5 is the only graph that showed point (0,5).

h(x) = f(x + 4) → Graph #6

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the x-values of f(x) by -4.

⭐ Graph #6 exhibits this transformation because I took point (0,1) and shifted it left 4 units to get (-4,1). Graph #6 is the only graph that showed point (-4,1).

k(x) = f(x) - 4 → Graph #4

⭐ This transformation of f(x) means that to get g(x), you have to shift all of the y-values of f(x) down by 4.

⭐ Graph #4 exhibits this transformation because I took point (0,1) and shifted it down 4 units to get (0,-3). Graph #4 is the only graph that showed point (0,-3)

m(x) = f(x - 4) → Graph #3

⭐ This transformation of f(x) means that to get to g(x), you have to shift all of the x-values of f(x) right by +4.

⭐ Graph #3 exhibits this transformation because I took point (0,1) and shifted it right 4 units to get (4,1). Graph #3 is the only graph that showed point (4,1).

I used a calculator on this so it must be correct

Pam needs to save $905 per year for seven years to have enough for her first year with the help of her two grandfathers.

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

To compare two numbers, a, and b, we can write two inequalities:

a < b when a is less than b

a > b when a is greater than b.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

We may write two inequalities to compare two numbers, a and b:

a < b

a > b

If a is less than b, then the first inequality is true and the second is false. If a is greater than b, then the first inequality is false and the second is true. Otherwise, if a and b are equal, then both inequalities are false.

We can determine which inequality is true by comparing the values of a and b and using the rules of inequality.

For example, if a=3 and b=5, then we can determine that a < b is true and a > b is false because 3 is less than 5.

On the other hand, if a=8 and b=2, then we can determine that a < b is false and a > b is true because 8 is greater than 2.

When two lines are crossed by a transversal, a number of angle pairs are formed. The sum of the measures of these angle pairs can be used to solve for unknown angles in the diagram.

Here are some of the angle pair relationships that hold for two lines crossed by a transversal:

Using these relationships, you can set up equations to solve for unknown angles in the diagram. For example, if you are trying to find the measure of angle A, you might use the fact that corresponding angles are congruent to set up the equation "m<A = m<D". Then, you can use other angle pairs to find the measures of the other angles, and solve the system of equations to find the measure of angle A.

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.

Ex. Because the zero point is set arbitrarily and does not indicate the complete absence of temperature, the Fahrenheit scale is an interval scale.

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).

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.

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

The best estimate of the solution to the system of equations will be (1, 4). Then the correct option is C.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The system of the equations is given below.

2x + 3y = 12            ...1

4x + 2y = 10           ...2

Divide the equation 2 by 2, then we have

2x + y = 5            ...3

Subtract equation 3 from equation 2, then we have

2x + 3y - 2x - y = 12 - 5

2y = 7

y = 3.5

y ≈ 4

Then the value of 'x' is calculated as,

2x + 3.5 = 5

2x = 1.5

x = 0.75

x ≈ 1

m is slope

c is y-intercept

We are given two equations of two lines as;
