The equation of the perpendicular line is y = (1/8)x + 15/4.

We are given the equation of a straight line. The equation is y = -8x - 3. The slope of the given line is -8. We need to find the equation of the straight line that is perpendicular to the given line and passes through the coordinates (2, 4).

The slope of the perpendicular line will be the negative reciprocal of the slope of the given line. Let the slope of the perpendicular line be represented by the variable "m".

m = -1/(-8) = 1/8

The equation of the perpendicular line using the slope-point form can be written as given below.

y = mx + c

y = (1/8)x + c

The line passes through the point (2, 4).

4 = (1/8)2 + c

4 = (1/4) + c

c = 4 - (1/4)

c = 15/4

Hence, the equation of the perpendicular line is y = (1/8)x + 15/4.

The complete question is given below.

Answer:

80y-24z

Step-by-step explanation:

A situation in which the person can afford 9 t-shirts and one 1-sweatshirts, but not 3 T-shirts and 8 sweatshirts are when the value of the gift card is $100 and the price of each t-shirt is $10.

The relation between two unequal expressions is defined as inequality.

Given that, the person can afford 9 T-shirts and 1 sweatshirt but not 3 t-shirts and 8 sweatshirts.

Let the value of the gift card be y.

Let the cost of one shirt and one sweatshirt be t and s respectively.

Then, the inequality for the condition that "the person can afford 9 T-shirts and 1 sweatshirt" is:
9t + s ≤ y

The inequality for the condition that " the person cannot afford 3 t-shirts and 8 sweatshirts" is:

3t + 8s > y

Now, let the person buys 1 sweatshirt in any situation, then from inequalities (1) and (2):

9t + 1 ≤ y

3t + 8 > y

Hence, the system of inequalities is:

9t + 1 ≤ y

3t + 8 > y

The graph of the inequalities is shown.

Let the value of the gift card be $100 and the price of each t-shirt is

t =$10, then

9(10) + 1 ≤ 100

91≤100, true

And,

3(10) + 8 > 100

38 > 100, false

Hence, a situation in which the person can afford 9 t-shirts and one 1-sweatshirts, but not 3 T-shirts and 8 sweatshirts are when the value of the gift card is $100 and the price of each t-shirt is $10.

The amount owed by the debtor is $10865

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865

Hence, the value of the amount after 6 years is $10865

The expression for the perimeter of the rectangle is 34u - 10 centimeters.

Perimeter of the rectangle:

Perimeter is known as the total length or distance of its boundary on all sides.

The formula that is used to calculate the perimeter of a rectangle is, perimeter of a rectangle = 2(l + w),

where 'l' is the length and

'w' is the width of the rectangle.

Given,

The width of the rectangle is (10u + 3) and the length of the rectangle is (7u - 8)

Now, we need to find the perimeter of the rectangle.

We know that the formula of the rectangle is

Perimeter = 2(l + w)

where l refers the length that is (7u - 8) and w refers the width that is (10u + 3).

Now, we have to apply these values on the formula, then we get,

=> Perimeter = 2((7u -8) + (10u + 3)

When we simplify the equation, then we get,

=> Perimeter = 2((10u + 7u) + (-8 +3))

=> Perimeter = 2(17u - 5)

=> Perimeter = 34u - 10

Therefore, the perimeter of the rectangle is 34u - 10 centimeters.

The farmer purchased a tractor for 50,000 so you start with that:

Remaining Amount = 50,000(1-r)^t

Decay rate would be 0.10 because you have to CONVERT 10% to decimal form.

Answer:

$23,914.85 (nearest cent).

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{9 cm}\underline{General form of an Exponential Function}\\\\$y=ab^x$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the initial value ($y$-intercept). \\ \phantom{ww}$\bullet$ $b$ is the base (growth/decay factor) in decimal form.\\\end{minipage}}[/tex]

The given scenario can be modelled as an exponential equation.

The initial value (a) is the purchase cost of the tractor.

As the tractor depreciates by 10% each year, the value of the tractor is 90% of the previous year's value. Therefore, the base (b) is 0.9.

Therefore, the equation is:

[tex]\boxed{y=50000(0.9)^x}[/tex]

where:

To find the value of the tractor in 7 years, substitute x = 7 into the equation:

[tex]\implies y=50000(0.9)^7[/tex]

[tex]\implies y=50000 \times 0.4782969[/tex]

The slope of the line which is perpendicular to the given line 3x+18y=108 is (6).

We already know the equation of a line in slope intercept form y = mx + b and we also know that perpendicular lines that have slopes which are negative reciprocals of each other.

Given a line 13x + 18y=108, this slope intercept form can be written as,

3x + 18y = 108

18y = 108 - 3x

y = (108 /18) - (3/18)x.

y = (6) - 1x/6.

y = -(1/6)x + 6.
