Step-by-step explanation:(4/100x)+(6/100y)=178---------(i)

2х+3y=8900-----------(i)

x+y=3600---------(ii)

where x is phone

y is pen

The system of equations that describes the situation are 4x + 6y = 17800 and x + y = 3600.

A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.

Let the cost of 1 phone is x dollars and cost of 1 computer is y dollars.

Cameron earns a 4% commission on the total dollar amount of all phone sales he makes and earns a 6% commission on all computer sales.

∴ (4/100)x + (6/100)y = 178

4x + 6y = 17800...(i)

Cameron made a total of $3600 in sales.

∴ x + y = 3600...(ii)

Now to solve the equations we'll multiply eqn(ii) by 4 or 6 to cancel out x or y, and then we'll substitute the numerical value of x or y in any of these equations.

The smallest integer is 1 and solution is (₋1)

Given, the inequality is 2x ₋ 8 ≥ ₋11

The mathematical expressions with inequalities are those with unequal sides on both sides. Unlike equations, we compare two values when we work with inequality. A statement that two things are not equal is what is meant by the word "inequality." It's possible for one of the items to be more than, smaller than, equal to, or equal to the other things.

now add 8 on both sides.

2x ₋ 8 ₊ 8 ≥ ₋11 ₊ 8

2x ≥ ₋3

dividing both sides by 2.

2x/2 ≥ ₋3/2

⇒ x ≥ ₋3/2

₋3/2 is not an integer.

hence the smallest integer value of x is 1, and solution is (₋1)

Hence we get the integer value as 1.

Just like polynomials and other expressions, you can perform basic arithmetic operations on rational expressions: addition, subtraction, multiplication, and division. A rational expression is a fraction whose numerator and the denominator is a polynomial. If f is a logical expression, then we can write f in the form of p/q, where p and q are polynomials.

Solution:

To find the restriction on a variable in the denominator, we Set the denominator equal to zero. Then we solve for X

So,

X+1 = 0

X = -1

X-4 = 0

X = 4

When we put the X= -1 or X= 4, we get 0 in the denominator, so these are restrictions variables

= (x2+4x+3)/(x2-3x-4)

= (x+1) (x+3)/(x+1) (x-4)

Now cancel the common factor (x+1)

= x+3x-4

The answer is 4. The generalized equation is y = f(x). So when the coordinate of x is 4, value of y is 2

Graph of the equation y= f(x) passes through the points (0,2), (2,4), (4,6), and (7,9).

In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.  

The points on the graph often represent the relationship between two or more things.

The coordinate plane comprises a horizontal line (x-axis) and a vertical line (y-axis), and it is divided into four quadrants named using roman numbers (I, II, III and IV).

The different points in a graph have coordinates written as ordered pairs (pairs of numbers within parentheses separated by a comma). The first number in an ordered pair (x, y) represents the value of x, and the second one represents the value of y for a given point.

Step-by-step explanation:

- For the second question you apply the same steps to #12 to get m^2-64

Answer:

40 psi

Step-by-step explanation:

We can see that the relationship is linear with pressure increasing by 5 psi for every extra 15 feet depth

The data is given from depth of 40 feet

At 40 feet, pressure = 10 psi  

At 55 feet, pressure = 15 psi

At 70 feet pressure = 20 psi

We have to use 40 as the base depth since there are no measurements less than that value. So relative depth is d - 40 and since for every 15', there is an increase of 5psi, the relative increase in pressure  per 15' is [tex]= \dfrac{d-40}{15}\cdot 5[/tex]

But the base pressure is 10psi not 0 so we have to add 10 to this equation to get the absolute psi

So the equation that connects depth (d) and pressure (p) is:

[tex]p = \dfrac{d - 40}{15}\cdot 5 + 10\\\\\textrm{At 130' depth},\\p = \dfrac{130-40}{15}\cdot 5 + 10\\= \dfrac{90}{15}\cdot 5 + 10\\\\= 30 + 10 = 40 psi\\[/tex]

If we plot these values, we can see they fit a straight line with slope = 1/3 and y-intercept = -10/3

The future value and interest earned when compounded semiannually are $13,576.14 and $4,871.58 respectively.

The future value and interest earned when compounded continuously are $13,651.47 and $4,946.91 respectively.

Compound interest is mathematically expressed as;

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

Given the data in the question;

a) Determine the accrued amount and interest when compounded semiannually ( n = 2 )

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

A = 8704.56(1 + 0.05/2)^( 2× 9 )

A = 8704.56(1 + 0.025)¹⁸

A = 8704.56(1.025)¹⁸

A = 8704.56(1.025)¹⁸

A = $13,576.14

Note that; A = Principal + Interest.

Interest = $13,576.14 - $8704.56 = $4,871.58

b) Determine the accrued amount and interest when compounded continuously.

A = P × e^(r × t)

A = 8704.56 × e^(0.05 × 9)

A = 8704.56 × e^0.45

A = $13,651.47

Note that; A = Principal + Interest.

Interest = $13,651.47 - $8704.56 = $4,946.91

The future value and interest earned when compounded semiannually are $13,576.14 and $4,871.58 respectively.

The quotient of 117 divided by 9 is 13.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

The answer thus got is called the quotient.

We have to divide 117 by 9.

Division algorithm states that,

Dividend = (Divisor × quotient) + Remainder

Remainder will be 0 if divisor is a factor of dividend.

Here dividend = 117 and divisor = 9

We know that 90 is a multiple of 9, where 90 = 9 × 10.

Remainder is 117 - 90 = 27

27 = 9 × 3

Hence 117 = 90 + 27 = (9 × 10 ) + (9 × 3) = 9 (10 + 3) = 9 × 13

So 117 / 9 = 13

Hence the quotient is 13.

Step-by-step explanation:

Step-by-step explanation:

let's just write it down in mathematical notation :

length = 2×width - 1

the perimeter is the way all around an object.

so, for a rectangle that is

2×length + 2×width

for our rectangle here

2×length + 2×width = 70

now we use the original identity of length via width and get

2×(2×width - 1) + 2×width = 70

4×width - 2 + 2×width = 70

6×width - 2 = 70

6×width = 72

width = 12

FYI

length = 2×width - 1 = 2×12 - 1 = 24 - 1 = 23
