Answer:

[tex]\sf y = \dfrac{5}{2}x +\dfrac{17}{2}[/tex]

Step-by-step explanation:

 [tex]\sf y =\dfrac{5}{2}x+1[/tex]

  m= 5/2

Parallel lines have same slope.

      Slope y-intercept form: y = mx +b

Here, m is the slope and b is the y-intercept

[tex]\sf y = \dfrac{5}{2}x + b[/tex]

Point (-3,1) passes through the required line. Substitute (-3,1) in the above equation and find 'b'.

        [tex]\sf 1 = \dfrac{5}{2}*(-3)+b\\\\1 =\dfrac{-15}{2}+b\\\\[/tex]

 [tex]\sf 1 +\dfrac{15}{2}=b\\\\\dfrac{2+15}{2}=b\\\\\\ \boxed{b= \dfrac{17}{2}}[/tex]

Using proportions, the number of planes in each city after 8 hours is given as follows:

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using operations such as multiplication and division, with the given ratios.

One example of application of proportions is for percentage problems, as the total amounts are multiplied by the decimal equivalent of the percentage to find the equivalent amounts.

The planes in Los Angeles after 8 hours are given as follows:

Hence the amount is:

0.7 x 30 + 0.25 x 12 + 0.125 x 8 = 25.

The planes in St. Louis after 8 hours are given as follows:

Hence the amount is:

0.2 x 30 + 0.25 x 12 + 0.5 x 8 = 13.

Initially, there were 50 planes, and 25 + 13 = 38 are in either Los Angeles or St. Louis, hence the remaining 50 - 38 = 12 are in Dallas.

Answer:

[tex]tan(x)=\frac{44\sqrt{89}}{89}[/tex]

Step-by-step explanation:

tan is defined as: [tex]tan(x)=\frac{opposite}{adjacent}[/tex]

sin is defined as: [tex]sin(x)=\frac{opposite}{hypotenuse}[/tex]

cos is defined as: [tex]cos(x)=\frac{adjacent}{hypotenuse}[/tex]

We can also define tan as: [tex]tan(x)=\frac{sin(x)}{cos(x)}[/tex]

because plugging in the definitions of sin and cos in we get: [tex]tan(x)=\frac{(\frac{opposite}{hypotenuse})}{(\frac{adjacent}{hypotenuse})}\\\\tan(x)=\frac{opposite}{hypotenuse}*\frac{hypotenuse}{adjacent}\\\\tan(x)=\frac{opposite}{adjacent}[/tex]

which you'll notice is the original definition of tan(x)

So using this definition of tan(x) we can use the givens sin(x) and cos(x) to find tan(x)

[tex]sin(x)=\frac{44}{45}\\\\cos(x)=\frac{\sqrt{89}}{45}\\\\tan(x)=\frac{sin(x)}{cos(x)}[/tex]

plugging in sin(x) and cos(x) we get:

[tex]tan(x)=\frac{\frac{44}{45}}{\frac{\sqrt{89}}{45}}\\\\tan(x)=\frac{44}{45}*\frac{45}{\sqrt{89}}\\\\tan(x)=\frac{44}{\sqrt{89}}[/tex]

We usually don't like square roots in the denominator, and from here we want to rationalize the denominator which we do by removing the square root from the denominator.

We can do this by multiplying the fraction by: [tex]\frac{\sqrt{89}}{\sqrt{89}}[/tex] which doesn't change the value of the fraction since it simplifies to 1, but it gets rid of the square root in the denominator

[tex]tan(x)=\frac{44}{\sqrt{89}}*\frac{\sqrt{89}}{\sqrt{89}}\\\\tan(x)=\frac{44\sqrt{89}}{89}[/tex]

Answer:

x° = 100°

Step-by-step explanation:

Straight line angles add up to be 180°

Angles opposite eachother aka "vertical angles" are the same measurements.

The equation of the line that is perpendicular to y = 2x + 3 and passes through the point (−4, 8) is y = - 1 / 2 x + 6(y equals negative one-half times x plus 6)

The equation of the line is perpendicular to y = 2x + 3 and passes through the point (−4, 8).

Therefore, perpendicular lines follows the rule:

m₁m₂ = -1

Hence,

2m₂= -1

m₂ = - 1 / 2

Therefore, let's find the slope of the line using (-4, 8)

8 = - 1 / 2 (-4) + b

b = 8 - 2

b = 6

Therefore, the equation of the line is y = - 1 / 2 x + 6

The given expressions have been evaluated to be equivalent or not equivalent as follows:

The distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a specific number, the same output (result) would be produced as when each addend is multiplied respectively by the number, and the products are added together.

Mathematically, the distributive property of multiplication is given by this expression:

a(b + c) = ab + ac.

Next, we would determine whether or not the given expressions are equivalent:

3x + 12 and 3(4 + x):

Opening the bracket, we have:

3(4 + x) = 3x + 12 (Equivalent).

2(3x - 30) and 6 - 30;

Opening the bracket, we have:

2(3x - 30) = 6x - 60

2(3x - 30) = 6 - 30 (Not equivalent).

4(5 - 4x) and 20x - 16;

Opening the bracket, we have:

4(5 - 4x) = 20 - 16x

4(5 - 4x) = 20x - 16 (Not equivalent).

The value of the area are;

Rectangle A = 54 square units

Triangle B = 2 square units

Rectangle C = 6 square units

Whole figure = 62 square units

The formula for determining the area of a rectangle is expressed as;

Area = lw

Where;

From the figure shown, we have two rectangles

Area of the bigger rectangle;

Length = 9

Width = 6

Now, substitute the value

Area = 9(6)

Multiply through

Area = 54 square units

Area of the smaller rectangle

Length = 9 - 7 = 2

Width = 9 - 6 = 3

Substitute the values

Area = 2(3)

Multiply through

Area = 6square units

The formula for area of a triangle is expressed as;

Area = 1/2 base× height

Base = 9 - 6 = 3

Height = 9 - 2 = 3

Substitute the value

Area = 1/ 2 ×2(3)

Area = 6/ 3

Area = 2

The total area = Rectangle A + rectangle B + Triangle

Total area = 54 + 6 + 2

Total area = 62 square units

Step-by-step explanation:

multiply both numbers together

The other side of the fence based on the information illustrated is 6.5 feet.

It should be noted that the perimeter of a rectangle is illustrated as:

= 2(length + width)

In this case, the width is given as 7/2 = 3.5 feet.

It should be noted that the perimeter is given as 20 feet.

Therefore, the length will be:

2(length + width) = 30

2(length + 3.5) = 20

2Length + 7 = 20

2L = 20 - 7

2L = 13

L = 13/2
