Answer:

it is B: yes the lines do not intersect at a 90 degree angle.

Step-by-step explanation:

if it intersected at a 90 degree angle, then it would have the 90 degree angle symbol and the figure would look like a cross, rather than an X shape.

here is an example of a figure that is perpendicular with a 90 degree angle:

Answer:

x = 2.8

Step-by-step explanation:

17x+1+20x-14 = 90

Combine like terms.

37x-13 = 90

Add 13 on both sides.

37x-13 = 90

     +13   +13

37x = 103

Divide both sides by 37.

37x = 103

/37     /37

x = 2.8

(I rounded up, but if you need a more specific number, just search up 103 divided by 37.)

Answer:

Width = 6 m and lenght = 7 m

Step-by-step explanation:

Let x be the width of the rectangle.

lenght = 2x - 5

Perimeter means the addition of all sides of the rectangle.

Thus, x + x + 2x - 5 + 2x - 5 = 26

2x + 2x + 2x = 26 + 10

6x = 36, x= 6

Therefore, width is 6 m and lenght is 2 (6) -5 == 7 m

Hope it helps :)

Answer:

x=5

Step-by-step explanation:

Set the 2 equations equal to each other and solve for x.

11x-28=7x-8

add 28 to both sides (-8+28=20)

11x=7x+20

subtract 7x from both sides (11x-7x=4x)

4x=20

divide both sides by 4 to isolate x (20/4=5)

x=5

Answer: (5x + 2)(5x+2)

Step-by-step explanation: I just did a quiz with the same question

The factor of the given expression are (5x + 2)(5x+2)

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

We will recognize that the first (25x^2) and last (4) terms are perfect squares. The middle term is double the product of the roots of those squares is;

 2(5x)(2) = 20x

Which means the given expression is a perfect square trinomial, and that it is the square of (5x+2).

 25x^2 +20x +4

= (5x +2)^2

= (5x +2)(5x +2)

Here, we have a=5x, b=2.

Answer:

5

Step-by-step explanation:

Answer:

d = 12.5

Step-by-step explanation:

Second term = a + d

Third term = a + 2d

a + d + a + 2d = 27

2a + 3d = 27

Fourth term = a + 3d

Fifth term = a + 4d

a + 3d + a + 4d = 77

2a + 7d = 77

2a + 3d = 27 (1)

2a + 7d = 77 (2)

Subtract (1) from (2) to eliminate a

7d - 3d = 77 - 27

4d = 50

Divide both sides by 4

d = 50/4

= 12. 5

d = 12.5

Substitute d = 12.5 into (1)

2a + 3d = 27

2a + 3(12.5) = 27

2a + 37.5 = 27

2a = 27 - 37.5

2a = -10.5

a = -10.5 / 2

= -5.25

a = -5.25

The common difference of the sequence is 12.5.

Given that,

The sum of the 2nd and 3rd terms of an arithmetic sequence is 27,

And the sum of the 4th and 5th terms is 77.

We have to determine,

The common difference of the sequence?

According to the question,

Let d is the common difference of the sequence,

The second term to the arithmetic series is,

[tex]\rm Second \ term= a+d[/tex]

And the third term to the arithmetic series is,

[tex]\rm Third \ term= a+2d[/tex]

The sum of the second and third terms of the sequence is 27.

[tex]\rm Second \ term + third \ term = 27\\\\a+d + a+2d = 27\\\\2a + 3d = 27[/tex]

The fourth term to the arithmetic series is,

[tex]\rm fourth \ term= a+3d[/tex]

And the fifth term to the arithmetic series is,

[tex]\rm fifth \ term= a+4d[/tex]

The sum of the fourth and fifth terms of the sequence is 77.

[tex]\rm fourth\ term + fifth \ term = 77\\\\a+3d + a+4d = 77\\\\2a + 7d = 77[/tex]

On solving both the equations,

[tex]\rm 2a + 3d = 27\\\\2a + 7d = 77[/tex]

Subtract equation 1 from equation 2,

[tex]\rm 2a + 3d - (2a + 7d) = 27-77\\\\2a +3d -2a-7d = -50\\\\-4d = -50\\\\d = \dfarc{-50}{-4}\\\\d = \dfrac{25}{2}\\\\d = 12.5[/tex]

Hence, The required common difference of the sequence is 12.5.

Answer:

y + 1 = [tex]\frac{3}{4}[/tex](x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (1, - 1) and (x₂, y₂ ) = (5, 2)

m = [tex]\frac{2+1}{5-1}[/tex] = [tex]\frac{3}{4}[/tex]

using (a, b) = (1, - 1 ), then

y - (- 1) = [tex]\frac{3}{4}[/tex](x - 1) , that is

y + 1 = [tex]\frac{3}{4}[/tex](x - 1)

The required price of a plastic watch in the sale is $2.40.

Given that,
to determine the sale price of a plastic watch originally priced at $4.80 if the sale is 50%.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
A plastic watch was originally priced at $4.80.
After 50% the price is = 50% * 4.80
                                     = 4.80 * 50 / 100
                                     = 4.80 * 1/2
                                     = $ 2.40

Thus, the required price of a plastic watch in the sale is $2.40.

Answer:

a = (3 + 2b) / 3

Step-by-step explanation:

1) Move 2b to the right.

-3a + 2b = -3

-3a = -3 - 2b

2) Leave only a on the left.

a = (-3 - 2b) / (-3)

a = -(3 + 2b) / (-3)

a = (3 + 2b) / 3
