Answer:

Choice a
y = 2x -5

Step-by-step explanation:

The slope-intercept form of a line is y = mx + b where m is the slope and b the y-intercept

The given line has slope = 2

A parallel line will have slope = 2 also

So the only choice is 2x + 5 which is choice a

Logarithmic scale: A measurement scale in which the position is marked using the logarithm of a value rather than the actual value.

A logarithmic equation includes a logarithm in the variable x.

An exponential equation is one in which the variable is represented by an exponent. A logarithmic equation is one in which the logarithm of a variable-containing expression is used.

For logarithmic equations, log b (x) = y is equivalent to b^y = x such that x > 0, b > 0 and b is not equal to 1.

In the given problem, b = 2, x = 1/2, and y = -1.

b =2

x = 1/2

y = -1

Substituting the values of b, x and y into the equation b^y = x;

2^(-1) = 1/2

therefore, the value of the given equation log₂1/2=1 is 1/2.

By applying the laws of indices to each of the expression, the simplified expressions are matched as follows:

An exponent can be defined as a mathematical operation that is used to raise a quantity to the power of another and it is generally written as bⁿ.

In Mathematics, laws of indices can be defined as the standard principles and rules that are used for simplifying a mathematical equation or expression that involves powers of the same base.

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In order to evaluate an expression, you should apply the PEMDAS rule, where operations within the parenthesis are first of all evaluated, followed by exponent, and then multiplication or division from the left side of the expression to the right. Lastly, the operations of addition or subtraction would be performed from left to right.

By applying the laws of indices to each of the expression, the simplified expressions are as follows:

5³ ÷ 5⁻¹ = 5⁽³ ⁻⁽⁻¹⁾ = 5⁽³ ⁺ ¹⁾ = 5⁴     ⇒ 5³ ÷ 5⁻¹ = 5⁴

5³ × 5⁻¹ = 5⁽³ ⁺ ⁽⁻¹⁾ = 5⁽³ ⁻ ¹⁾ = 5²

a⁻ⁿ = 1/aⁿ ≡ 5⁻⁴ = 1/5⁴

Step-by-step explanation:

0.3(6y+15)=1.8y+4.5

Step 1: Simplify both sides of the equation.

0.3(6y+15)=1.8y+4.5

(0.3)(6y)+(0.3)(15)=1.8y+4.5(Distribute)

1.8y+4.5=1.8y+4.5

Step 2: Subtract 1.8y from both sides.

1.8y+4.5−1.8y=1.8y+4.5−1.8y

0y+4.5=4.5

Step 3: Subtract 4.5 from both sides.

0y+4.5−4.5=4.5−4.5

0y=0

Step 4: Divide both sides by 0.

0y/0 = 0/0

y=0

The constraints of the equation will be x > 13 y and 340 x + 670 y < 5650.

Let the number of new bicycles be x

Let the number of new treadmills be y.

Cost of 1 new bicycle = $ 340

Cost of 1 new treadmill = $ 670

Also, he must spend less than $ 56,50

Now, the constraints for this will be:

x > 13 y

x greater than 13 y

340 x + 670 y < 5650

340 x plus 670 y less than or equal to 5650

Therefore, the constraints of the equation will be x > 13 y and 340 x + 670 y < 5650 .

Answer:

(1, 7 )

Step-by-step explanation:

- 2x - 4y = - 30 → (1)

- x + y = 6 → (2)

multiplying (2) by 4 and adding to (1) will eliminate y

- 4x + 4y = 24 → (3)

add (1) and (3) term by term to eliminate y

- 6x + 0 = - 6

- 6x = - 6 ( divide both sides by - 6 )

x = 1

substitute x = 1 into either of the 2 equations and solve for y

substituting into (1)

- 2(1) - 4y = - 30

- 2 - 4y = - 30 ( add 2 to both sides )

- 4y = - 28 ( divide both sides by - 4 )

y = 7

solution is (1, 7 )

Mr. Lawson is to pay the smallest amount of interest that is allowed in the City Credit Union which is a simple interest would be 1632.

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100

To determine the smallest amount of interest.

We have to calculate the simple interest of each bank

United Bank : 4% interest rate and 6 years

S.I. of United Bank = 8000 × 4/100 × 6 = 1920

Nations First :3.8% interest rate and 7 years

S.I. of Nations First = 8000 × 3.8/100 × 7 = 2128

City Credit Union :5.1% interest rate and 4 years

S.I. of City Credit Union = 8000 × 5.1/100 × 4 = 1632

Priority Bank : 4.2%interest rate and 5 years.

S.I. of Priority Bank = 8000 × 4.2/100 × 5 = 1680

So the smallest amount of interest would be City Credit Union which is 1632.

Therefore, Mr. Lawson is to pay the smallest amount of interest that is allowed in the City Credit Union which is a simple interest would be 1632.

The value of y or the perpendicular of the is 180 rounded to nearest tenth.

Here we have to use Trigonometry

Trigonometry is basically the study of the relationship between the sides and angles of the right-angle triangle.  Thus , trigonometry helps to find the missing or unknown angles or sides of a right-angle triangle using the trigonometric formulas, functions or trigonometric identities. In trigonometry, the angles can be are generally  measured in degrees

Here we will use Tan α

Tan α = Perpendicular / Base

From the given figure we know that base is given as 350 feet and α is 27°

Tan 27° = y/ 350

0.509 = y / 350

y = 350 × 0.509

Adult tickets costs $63.8

Children tickets costs $13.2

Let x represent the adult tickets and y to represent the cost of children tickets

x + y= 77..........equation 1

36x + 17y= 2,297........equation 2

From equation 1

x= 77-y

Substitute 77-y for x in equation 2

36(77-y) + 17y = 2297

2772 - 36y= 2297

-36y= 2297-2772

-36y= -475

y= 475/36

y= 13.2

Substitute 13.2 for y in equation 1

x + 13.2 = 77

x= 77-13.2
x= 63.8

Hence adult tickets costs $63.8 and children tickets costs $13.2

If Carl Brownstein is a golf course groundskeeper whose annual gross pay is 45,500, and he has exemptions of 3000, and the state tax on the first 2500 is 1.5% and 3% on amounts over 2,500 then the state income tax of Carls is C- 1237.50.

The state income tax of Carls can be calculated as follows;

First, we subtract the exemption of 3000 from the annual gross pay as follows;

45500 - 3000 = 42500

As the percentage tax on the first 2500 is 1.5%, it can be calculated as follows;

1.5/100 × 2500 = 0.015 × 2500 = 37.50

The percentage tax on amounts over 2500 is 3%, therefore we can calculate the tax on the remaining amount as follows;

42500 - 2500 = 40000

3/100 × 40000 = 0.03 × 40000 = 1200

The total state income tax can be calculated by addition;

Tax on the first 2500 + Tax on the amount over 2500

37.50 + 1200 = 1237.50

Hence the state income tax of Carl is calculated to be 1237.50

Depreciation means value falling

10 is the scrap value which means the value that will remain after the product is properly used up.

depreciation for one year will be calculeted through

(original value - scrap value)/ no of years of use

(500 - 10)/3

= 163 is the annual rate of depreciation

If no scrap value is given, then you will simply divide the value by the no. of years of use

b. annual depreciation = 163

original value = 500

500 - 163(x) = worth of the poster after x years
