Answer:

mathematics is important so you know how to solve problems. there are a lot of ways in the future you might use math. you use math in other subject too.

Step-by-step explanation:

Answer:

The slope would be 5, answer B.

You can find this by doing y2 - y1/ x2 - x1.

Hope this helps.

Answer:

8.) x=115 degrees

9.) y=102 degrees

Step-by-step explanation:

8.) A triangles total degrees is 180, so 180-50=130. now the missing angles are congruent, so 130/2=65. and now we're working on the bottom right angle. which is 65. what we need can be added to the angle we just found to add up to 180, so reverse it. 180-65=115. so x=115 degrees.

9.) because y is congruent to the angle across from it, we can just assume y and 78 is equal to 180. 180-78=102. so y=102 degrees. Hope this helps!

Answer:

5x-(-4x-6) = 10

Step-by-step explanation:

Given the expression

y=−4x−6 ..... 1

5x−y=10... 2

To get the required equation we will substitute equation 1 into 2

5x-y = 10

5x-(-4x-6) = 10

5x+4x+6 = 10

9x+6 = 10

9x = 4

x = 4/9the required equation is 5x-(-4x-6) = 10

Answer:

5x - (-4x - 6) = 6

Answer:

Two squares are congruent if they have the same side length

Step-by-step explanation:

The dimensions of a square are the side length of the square and in a square, all sides are equal

Therefore, given that two quadrilaterals are squares, and the side length of each of the given quadrilateral are equal, the quadrilateral are said to be congruent.

Answer:

Option (C)

Step-by-step explanation:

Let the relation between amount of money (m) and Time (t) is represented by the equation,

m = ct + b

Where c = Investment per week

b = Ben already had the amount before investment

From the question,

c = $5 per week

b = $100

Therefore, equation will be,

m = 5t + 100

If duration of the investment 't' = 8 weeks

Amount in the account after 8 weeks,

m = 5(8) + 100

m = $140

Option (C) is the correct option.

Answer:

  C.  x ≥ 1

Step-by-step explanation:

The content of the radical must be non-negative in both cases. The square of x is already non-negative for any x.

  15(x -1) ≥ 0

  x -1 ≥ 0 . . . . divide by 15; next, add 1

  x ≥ 1 . . . . . matches choice C

Complete Question:

The growth of baby girl Claire is displayed in the graph below. (4, 22) (14, 30)

Answer:

Point Slope: [tex]y - 22 = 0.8(x - 4)[/tex]

Slope Intercept: [tex]y = 0.8x +18.8[/tex]

y intercept: [tex]b = 18.8[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (4,22)[/tex]

[tex](x_2,y_2) = (14,30)[/tex]

Solving (a) Point slope

Using point slope form, an equation is of the form

[tex](y_2 - y_1) = m(x_2 - x_1)[/tex]

First, we need to solve for slope (m):

Make m the subject

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substitute values for x and y

[tex]m = \frac{30 - 22}{14 - 4}[/tex]

[tex]m = \frac{8}{10}[/tex]

[tex]m = 0.8[/tex]

Next, we form a linear relationship

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

Where

[tex]m = 0.8[/tex] and [tex](x_1,y_1) = (4,22)[/tex]

[tex]y - 22 = 0.8(x - 4)[/tex]

Solving (b): Slope Intercept

[tex]y - 22 = 0.8(x - 4)[/tex]

Open Bracket

[tex]y - 22 = 0.8x - 3.2[/tex]

Add 22 to both sides

[tex]y - 22 +22= 0.8x - 3.2 + 22[/tex]

[tex]y = 0.8x +18.8[/tex]

Solving (c): The y intercept

The general form of an equation is:

[tex]y = mx + b[/tex]

Where b represents the y intercept

By comparison with [tex]y = 0.8x +18.8[/tex]

[tex]b = 18.8[/tex]

1/2 x 3/4 = x

x =

3/8

or rather

0.375

The resultant of multiplication of fraction 1/2 x 3/4 is 3/8.

What is mathematic expression?

A mathematical expression expression in mathematical is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Here it is given the multiplication of fractions 1/2 x 3/4 which can be solved by multiplying 1 and 3 of numerator and placing at numerator of result and also by multiplying 2 and 4 of denominator and placing at denominator  of result.

1/2 x 3/4 = (1x3)/ (2x4) = 3/8

Therefore, the resultant of multiplication of fraction 1/2 x 3/4 is 3/8.

Answer:

Step-by-step explanation:

Expanding the first statement using the distributive property yields -1.5x - 2.5. The two formulations are not equal because the constant term does not have the same sign as the second expression. Furthermore, if you replace x with a value and evaluate each equation, the results will not be equal.

Answer:

B.  [tex]Cos ^{-1}[/tex] [tex]\frac{6.3}{9.8}[/tex]

E.  [tex]Sin^{-1}[/tex] [tex]\frac{7.5}{9.8}[/tex]

Step-by-step explanation:

The trigonometric functions are applied when given a side and one of the angles of a right angled triangle.

Sine θ = [tex]\frac{opposite}{hypotenuse}[/tex]

Cosine θ = [tex]\frac{adjacent}{hypotenuse}[/tex]

Tangent θ = [tex]\frac{opposite}{adjacent}[/tex]

Given that; hypotenuse = 9.8, opposite side = 7.5 and adjacent side = 6.3.

Then,

Sin θ = [tex]\frac{7.5}{9.8}[/tex]

⇒ θ = [tex]Sin^{-1}[/tex] [tex]\frac{7.5}{9.8}[/tex]

Also,

Cos θ = [tex]\frac{6.3}{9.8}[/tex]

⇒ θ = [tex]Cos ^{-1}[/tex] [tex]\frac{6.3}{9.8}[/tex]

So, the appropriate answers to the given questions are options B and E.

Total number of matches = 306 matches

Step-by-step explanation:

Given:

Total number of team = 18

Per team number of play = 2

Find:

Total number of matches

Computation:

Total number of matches = [(Total number of team x 2)(Total number of team -1)]/2

Total number of matches = [(18 x 2)(18-1)]/2

Total number of matches = 612 / 2

Total number of matches = 306 matches
