The total amount accrued, principal plus interest, from simple interest on a principal of $1,500.00 at a rate of 3.5% per year for 30 years is $3,075.00. With a principal of £1,500.00 and an interest rate of 3.5% over a 30-year period, Sarah-Jane will save UK £1,575.00. It is undoubtedly a wise investment because the original UK £1,500 doubled.
What is Simple Interest?Simple interest is a quick and simple formula for figuring out how much interest will be charged on a loan. The daily interest rate, the principal, and the number of days between payments are multiplied to calculate simple interest.
What is the formula for Simple interest?A = P(1 + RT)
A=Final Amount
P = Principal
R = Rate of Interest
T = Time period
Here,
A = $3,075.00
I = A - P = $1,575.00
A = P(1 + rt)
First, converting R percent to r a decimal
r = R/100 = 3.5%/100 = 0.035 per year.
Solving our equation:
A = 1500(1 + (0.035 × 30)) = 3075
A = $3,075.00
$3,075.00 is the total amount accrued from simple interest on a principal of $1,500.00 at a rate of 3.5% per year for 30 years (principal plus interest). In a 30-year loan with a £1,500.00 principal and a 3.5% interest rate, Sarah-Jane will save UK £1,575.00. The original UK £1,500 doubled, so it is unquestionably a smart investment.

What is the equation of a line that passes through the point (2, −10) and is parallel to 14x+2y=6 ?
Enter your answer in the box.
The equation of the line passes through (2, -10) and to parallel to 14x +2y = 6 is 7x + y = 4
In the above question,
The equation of the line = 14x + 2y = 6
2y = 6 - 14x
y = [tex]- \frac{14x - 6}{2}[/tex]
y = -(7x - 3)
y = -7x + 3
The inclination of a line with respect to the horizontal is measured numerically is called as Slope
Slope of the given line = -7
The slope of a line parallel to the given line would be the same as they both are parallel to each other, hence the needed line's slope is also -7
The point through which is passes = (2, -10)
We need to find the equation of the line which passes through (2, -10) and to parallel to 14x +2y = 6
The equation of a line parallel to the given 14 x + 2 y = 6, and passing through the point (2, -10) is
[y - (-10)] = (-7)[x - 2]
y + 10 = -7x + 14
7x + y = 14 - 10
7x + y = 4
Hence, the equation of the line passes through (2, -10) and to parallel to 14x +2y = 6 is 7x + y = 4

Under her cell phone plan, Mayerlin pays a flat cost of $55 per month and $5 per
gigabyte. She wants to keep her bill under $70 per month. Write and solve an
inequality which can be used to determine x, the number of gigabytes Mayerlin can
use while staying within her budget.
The inequality can be represented as 55 + 5x < 70
what is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:

What is the value of x?
V
Answer:
x = 20
Step-by-step explanation:
4x + 1 and 2x + 41 are alternate exterior angles and are congruent , then
4x + 1 = 2x + 41 ( subtract 2x from both sides )
2x + 1 = 41 ( subtract 1 from both sides )
2x = 40 ( divide both sides by 2 )
x = 20

[tex]g(f(\text{x})) = -3\text{x}^2+3[/tex]
[tex]g(f(2)) = -9[/tex]
=======================================================
Explanation:
Let's compute g(f(x))
We do this by starting with the outer function g(x). Then replace every x with f(x). Then plug in the definition of f(x) as shown below.
[tex]g(\text{x}) = \text{x}-1\\\\g(f(\text{x})) = f(\text{x})-1\\\\g(f(\text{x})) = 4-3\text{x}^2-1\\\\g(f(\text{x})) = -3\text{x}^2+3\\\\[/tex]
At this point, we then plug in x = 2 so we can find that...
[tex]g(f(\text{x})) = -3\text{x}^2+3\\\\g(f(2)) = -3(2)^2+3\\\\g(f(2)) = -3(4)+3\\\\g(f(2)) = -12+3\\\\g(f(2)) = -9\\\\[/tex]

A literal equation is one that is mostly made up of letters. Examples of literal equations include formulas.
What is literal equation?A literal equation is one that is mostly made up of letters. Examples of literal equations include formulas. Every variable in the equation "literally" represents a crucial aspect of the overall relationship that the equation expresses. Multiple letters or variables make up a literal equation. Examples include the formula for calculating speed (v=Dt) and the area of a circle (A=r2). In this part, we resolve straightforward one-variable equations.
Alternatively,
Ax +By = C
Any sign that crosses over equal(=) signs always change
In this case, Ax crosses over to C
By = C - Ax
To eliminate y from By, then
By/y = (C - Ax) /y
y cancel out y on the left side
B = (C - Ax) /y

Danae is choosing between two jobs. One job pays an annual bonus of $1,500 plus $120 per day worked. The second job pays an annual bonus of $2,500 plus $110 per day worked. Which equation can be solved to determine after how many days, d, Danae would make the same amount of money regardless of the job she chooses?
a.) 120d + 110d = 1,500 + 2,500
b.) 120 + 110 = 1,500d + 2,500d
c.) 120d + 1,500 = 110d + 2,500
d.) 120d + 2,500 = 110d + 1,500
The equation that can be solved to determine the number of days when both jobs would have the same cost is 120d + 1,500 = 110d + 2,500.
What is the equation?The equations that would be formed would be linear equations. A linear equation is an equation that has a single variable that is raised to the power of one. A linear equation is a straight line when it is drawn on a graph.
The equation that represents the total bonus of the first job is: fixed pay + total variable pay

1,500 + 120d
The equation that represents the total bonus of the second job is: fixed pay + total variable pay
$2,500 + ($110 x d)
$2,500 + $110d
When the amount at both jobs are equal, the two above linear functions would be equal
