What is line equation?
For a line equation for the form of y=m x+b, the slope is m. m=7
The first step to answering this question is to find the slope of the first line. To do that, we need to put it in slope-intercept form.
y=7x+5 => y=7x+5
So the slope of this line is 7. Perpendicular lines have a negative reciprocal slope, so the slope of the perpendicular line is 7. Using that and the point (1,3) we can make an equation for the line in point-slope form: We can then convert this into slope intercept form.
=> y=7x+5

If I was born in 2008, how many years do I need to be 18?
Answer:
4 more years
Step-by-step explanation:
you were born in 2008, you should be 14 now or soon, by the end of the year. So 4 in 4 years you would be 18.
Answer: Simple, you are 14 right? So 4 more years
Step-by-step explanation:
Add 14+4 and you'll get 18.
Suppose you deposit $100 in Account A with
a simple interest rate of 3.4%, and $300 in
Account B with a simple interest rate of 1.8%.
One year later, you get
a bank statement
that
shows the interest for Account A is
$3.40 and the
interest for Account B is $540.00.
a. Which account statement is incorrect?
b. What may have been the bank's error?
The account statement for Account B is incorrect.
What is simple rate of interest?
Simple rate of interest is a type of interest calculation where interest is calculated only on the principal amount of a loan. Simple interest is calculated periodically, usually monthly or annually, as a fixed percentage of the principal. It is different from compound interest, which applies interest to both the principal and the accumulated interest. It is simpler to calculate than compound interest, and is generally used for short-term loans.
Given: Account A: $100, 3.4% and Account B: $300, 1.8%
We know, Simple Interest = Principal × Rate × Time
Interest for Account B = $300 × 1.8%
= $5.40
The bank statement after one year should be $5.40 instead of $540.00.
Hence, Account B's statement is incorrect.

A state seal, which is round, hangs in the capitol building. It has a radius of 2 yards. What is the seal's diameter?
Step-by-step explanation:
you do understand that the diameter of a circle is simply 2 times the radius, yes ?
imagine a circle and you draw a radius line (from the center of the circle to the circle arc).
and now imagine to draw another radius line, just in the opposite direction.
when you look at the result, you have 1 straight line going from the circle arc to the circle arc and passing through the center of the circle. that is what a diameter is.
how long is it ? well, we drew 2 radius lines to create this line. so, it is 2×radius long.
so, the diameter of the seal is
2×2 = 4 yards
If ur good at geometry can u help Solve for m given that the perimeter of the triangle is 19 centimeters.
Answer:
m = 7cm
Step-by-step explanation:
Perimeter of a triangle is all the sides added up, so a+ b + c.

the initial population of a town is 100,231 and it grows with a doubling time of 98 years. what will the population be in 31 years?
If the initial population of a town is 100,231 and it grows with a doubling time of 98 years, the population after 31 years is 124803
The initial population of the town = 100231 people
The doubling time = 98 years
We have to find the population in 31 year
The exponential function will be
f(t) = fo(2)^(t/98)
f(t) is the population of the town in t years
fo is the population of the town in t = 0 years
t is the number of years
2 because it doubling time
The value of t = 31 years
Substitute the values in the function
f(31) = 100231×(2)^(31/98)
Do the arithmetic operations
f(31) = 100231 × 1.245
f(31) = 124803.23
f(31) ≈ 124803
Therefore, the population after 31 years is 124803

The explicit formula for the given arithmetic sequence is aₙ = 23 + (n - 1)11. Here the first term is a1 = 23 and the common difference is d = 11.
What is the explicit formula for an arithmetic sequence?The explicit formula for an arithmetic sequence gives the nth term of the sequence. I.e.,
aₙ = a1 + (n - 1)d
Here a1 is the first term; d is a common difference, it is calculated by
d = aₙ₊₁ - aₙ = aₙ₋₁ - aₙ
Calculation:The given sequence is 23, 34, 45, 56,...
Here the first term a1 = 23
So, the common difference between the terms in the sequence is
d = 34 - 23 = 11
Then, the explicit formula for the given sequence is
aₙ = a1 + (n - 1)d
⇒ aₙ = 23 + (n - 1)11

The circumference of a circle is 11π cm. What is the area, in square centimeters? Express your answer in terms of π.
Answer:
The area of the circle is 30.25π cm^2.
Step-by-step explanation:
The circumference of a circle is equal to the diameter of the circle times π. Therefore, if the circumference of the circle is 11π cm, the diameter must be 11 cm.
The formula for the area of a circle is A = πr^2, where r is the radius of the circle. The radius of the circle is half the diameter, so the radius is (1/2) * 11 cm = 5.5 cm.
Substituting this value for r into the formula for the area of a circle, we get:
A = π * (5.5 cm)^2
= π * 30.25 cm^2
= 30.25π cm^2
Therefore, the area of the circle is 30.25π cm^2.

the coupon
When we apply coupon before promotional discount, we have to pay $396.
When we apply promotional discount first and then coupon, we have to pay $392
Given,
The coupon amount = $40
Promotional discount = 10%
The rent per hour = $100 + 20% gratuity
The rent for 4 hours including gratuity = (100 × 4) + (100 × 4 + 10/100) = $480
We have to find the amount for the situations given below;
a) The coupon is applied before the promotional discount;
Here,
Coupon deduction;
480 - 40 = $440
Promotional discount deduction;
10% of 440 = 44
Then,
440 - 44 = $396
We have to pay $396.
b) The promotional discount is applied before coupon;
Here,
Promotional discount deduction;
10% of 480 = 48
Then,
480 - 48 = $432
Coupon deduction;
432 - 40 = $392
