Can someone please help me

Answer:

5

Step-by-step explanation:

A square is a regular polygon. It has four lines of symmetry and four sides.

A regular pentagon has 5 sides and 5 lines of symmetry. The number of lines of symmetry in a regular polygon is equal to the number of sides.

When the folded part sits perfectly on top (all edges matching), then the fold line is a Line of Symmetry.

Answer:

5). y = -2x + 8

6). y = (4/3)x + 1

Step-by-step explanation:

5).

First find the slope

(y2 - y1) / (x2 - x1)  or rise/run

(2 - 0) / (2 - 3) = -2

-2 is your slope

Now use the equation below for using coordinates for finding slope intercept form.

y - y1 = m(x - x1)

y1 = y number of given coordinate

x1 = x number of given coordinate

m = slope

y - 2 = (-2)(x - 2)

Distribute

y - 2 = -2x + 4

Get y by itself by adding 2 to both sides.

y - 2 = -2x + 4

  +2           +2

y = -2x + 8

6).

Repeat the same process for 6 as done in 5

Find the slope

(y2 - y1) / (x2 - x1)  or rise/run

(5 - 1) / (3 - 0) = 4/3

4/3 is your slope

Now use the equation below for using coordinates for finding slope intercept form.

y - y1 = m(x - x1)

y1 = y number of given coordinate

x1 = x number of given coordinate

m = slope

y - 5 = (4/3)(x - 3)

Distribute

y - 5 = (4/3)x + (-4)

Get y by itself by adding 5 to both sides.

y - 5 = (4/3)x + (-4)

  +5                  +5

y = (4/3)x + 1

Answer:

The first answer = t ≥-7

Step-by-step explanation:

If one side of an inequality is multiplied by a negative number, to find an equivalent inequality the “direction” of the inequality has to change (for example, ≥ has to change to ≤ ). Find a so that y > x is equivalent to − 3 y < a x.

The real part is positive and imaginary negative, hence the sum of the complex number will be in the 4th quadrant

The standard representation of complex number is given as z = x+iy

where

x is the real part

y is the imaginary part

From the graph shown;

z1 = 7 + 3i

z2 = -3 - 5i

Take the sum

z1+z2 = (7-3) +(3i-5i)

z1 + z2 = 4 - 2i

Since the real part is positive and imaginary negative, hence the sum of the complex number will be in the 4th quadrant

[tex](10.3(2.5)+3.1(2))\div 110[/tex]

Step-by-step explanation:

[tex]A_1[/tex] = Area of 1st rectangle = [tex](10.3\times 2.5)\ \text{ft}^2[/tex]

[tex]A_2[/tex] = Area of 2nd rectangle = [tex](3.1\times 2)\ \text{ft}^2[/tex]

Answer:

Ratio of two corresponding sides of the similar kites = 3/8

Step-by-step explanation:

A kite has two pairs of congruent consecutive sides

Perimeter of a kite, P = 2(a + b)

Let the sides of the first kite be a and b; and the side of the second kite be e and f

Kite ABCD:

24 = 2(a + b)

12 = a + b

a = 12 - b

Kite EFGH

64 = 2(e + f)

32 = e + f

e = 32 - f

For a kite to be similar, the ratio of the side must be the same.

Considering a to correspond to e and b to correspond to f, therefore:

b/f = 12 - b/32 - f

32b - bf = 12f - bf

32b = 12f

b/f = 12/32

b/f = 3/8

Answer:

a = 3, b = -1

Step-by-step explanation:

a = 5b + 8

a = -10b - 7

5b + 8 = -10b - 7

Add 10b from both sides;

15b + 8 = -7

Subtract 8 from both sides;

15b = -15

Divide both sides by 15;

b = -1

Lets substitute b;

a = 5b + 8

a = 5(-1) + 8

a = -5 + 8

a = 3

Step-by-step explanation:

Given

Direct variation between y and x

Where x represents hours and y represents number of buttons

y = 2450 when x = 7

Required

Solve for x when y = 5250

Since it's a direct variation, we have that

2450 buttons = 7 hours

5250 buttons = x

Cross Multiply both expressions

2450 * x = 7 * 5250

2450x = 36750

Divide through by 2450

x = 36750/2450

x = 15

Hence, it'll take 15 hours to manufacture 5250 buttons

Step-by-step explanation:

-12 is your answer. We start by multiplying -3 four times, so multiplying a positive and a negative equals a negative: (+)x(-)=(-)

Answer: -12

Explanation: When multiplying integers, if the signs are the same, the product is positive, and if the signs are different, the product is negative.

Since the signs are different, the product is negative.

So a positive times a negative always equals a negative.

Therefore, 4 × -3 = -12.

Answer:
