Answer:

Explanation is written below.

Step-by-step explanation:

                                                1)

Given the line

[tex]y = -4x + 8[/tex]

Comparing with the slope-intercept form of the line equation

[tex]y=mx+b[/tex]    

Where m is the slope and b is the y-intercept

So, the slope of the line = m = -4

Thus, the equation of the line that is parallel to y = -4x + 8 and passes through the point (5, 1), using point slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]  

Here, m is the slope and (x₁, y₁) is the point

substituting the values m = -4 and the point (5, 1)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

y-1 = -4 (x - 5)

y-1 = -4x+20

y = -4x+20+1

y = -4x + 21

                                                    2)

Given the equation

[tex]y = -4x + 8[/tex]

Comparing with the slope-intercept form of the line equation

[tex]y=mx+b[/tex]    

Where m is the slope and b is the y-intercept

So, the slope of the line = m = -4

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: 1/4

Thus, an equation of the line that is perpendicular to y = -4x + 8 and passes through the point (5,1), using point slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]  

Here, m is the slope and (x₁, y₁) is the point

substituting the values m = 1/4 and the point (5, 1)

[tex]y-1\:=\:\frac{1}{4}\:\left(x\:-\:5\right)[/tex]

Add 1 to both sides

[tex]y-1+1=\frac{1}{4}\left(x-5\right)+1[/tex]

[tex]y=\frac{1}{4}x-\frac{1}{4}[/tex]

Answer:

4 kg of sugar would contain [tex] 1.2 \times 10^9 [/tex] crystals.

Step-by-step explanation:

Given that 3kg of sugar contains 9 × 10⁸ crystals, let "x" represent the number of sugar crystals 4kg of sugar would contain.

Thus, set up a proportion as follows:

3 kg : 9 × 10⁸ = 4 kg : x

[tex] \frac{3}{9 \times 10^8} = \frac{4}{x} [/tex]

Solve for x. Cross multiply.

[tex] 3 \times x = 9 \times 10^8 \times 4 [/tex]

[tex] 3x = 36 \times 10^8 [/tex]

[tex] 3x = 3.6 \times 10^9 [/tex]

Divide both sides by 3

[tex] \frac{3x}{3} = \frac{3.6 \times 10^9}{3} [/tex]

[tex] x = 1.2 \times 10^9 [/tex]

4 kg of sugar would contain [tex] 1.2 \times 10^9 [/tex] crystals.

Answer:

1/4

Step-by-step explanation:

The drawing of the square is introduced in the image attached below.

In this question we must determine the location of the four vertices of the square. A square is a quadrilateral with four sides of equal lengths and four right angles. Hence, the side length equals a quarter of the perimeter. The locations of all points can be found by using the following three operations:

[tex]B(x,y) = A(x,y) + (5, 0)[/tex]  (1)

[tex]C(x,y) = B(x,y) + (0, 5)[/tex]   (2)

[tex]D(x,y) = C(x,y) + (-5,0)[/tex]   (3)

If we know that [tex]A(x,y) = (-3, 5)[/tex], then the coordinates of the remaining vertices are:

[tex]B(x,y) = (-3, 5) + (5,0)[/tex]

[tex]B(x,y) = (2,5)[/tex]

[tex]C(x,y) = (2,5) + (0,5)[/tex]

[tex]C(x,y) = (2, 10)[/tex]

[tex]D(x,y) = (2,10) + (-5, 0)[/tex]

[tex]D(x,y) = (-3, 10)[/tex]

Now we draw the square with a graphing tool (i.e. Desmos).

Answer: $284.80

look when you are trying to find the percent of a number you need to turn the percent into a decimal then multiply the decimal by the number:

1st. 40% as a decimal is 0.40 because as a fraction 40% is 40/100 so that means that 1.00 is 100 and 0.40 is 40%

Answer:

Figure 1: x = 120°

Figure 2: x = 54°

Figure 3: x = 64°

Step-by-step explanation:

Every triangles interior angles will add up to 180°

Figure 1: 30 + 30 + x = 180

60 + x = 180

x = 120

Figure 2: 104 + 22 + x = 180

126 + x = 180

x = 54

Figure 3:

part 1: 154 + z = 180

z = 26

part 2: 90 + 26 + x = 180

116 + x = 180

x = 64

Answer:

1. 120

2. 54

3. 64

Step-by-step explanation:

1.

   30 + 30 = 60

   180-60 = 120

2.

    104 + 22 = 126

    180 - 126 = 54

3.

    180 - 154 = 26

    26 + 90 = 116

Answer:

X=3

Step-by-step explanation:

this is a heptagon (7sides) so all the angles must add to 900 degrees

you have to add them all up

135+(5x-4)+(3x+31)+(4x+15)+(6x-8)+120+(7x-64)=900

25x+225=900

25x+225-225=900

25x=675

25x/25=675/25

x=3

The value of x in the given hexagon is 19.8°.

A polygon is a closed more than two-sided and can be made up of a finite number of straight line segments and is a type of planar figure in geometry.

Each line of the polygonal circuit's segments is referred to as its edges or sides.

We know the sum of interior angles in a hexagon is 720°.

∴ 135° + (5x - 4)° + (3x + 31)° +  (7x - 64)° +  (4x + 15)° +  (6x - 8)° +  120° = 720°.

5x + 3x + 7x + 4x + 6x = (720 - 135 + 4 - 31 + 64 - 15 + 8 - 120)°.

25x = 495°.

x = 19.8°.
