Explain the properties used to solve inequalities and how they are different from properties of equality

The lengths of the four sides of such a quadrilateral as indicated in the task content are; 26, 27, 28 and 29.

It follows from the task content that the length of the four sides of the quadrilateral in discuss be determined.

Since the lengths are consecutive integers, we can take.the lengths as;

x, (x+1), (x+2), (x+3).

Hence, the sum of the lengths is equal to 110 as follows;

x + (x+1) + (x+2) + (x+3) = 110

4x + 6 = 110

4x = 104

x = 26 which is the shortest of all sides.

Ultimately, the length of the four sides are; 26, 27, 28 and 29.

The coordinate of point B from the given coordinates is (6, -9)

The formula for calculating the midpoint of coordinates is expressed according to the formula:

M(x, y) = {(x₁+x₂)/2, (y₁+y₂)/2}

Given the coordinate points M (2, -2) and A (-2, 1)

Substitute

2 = (x₁+x₂)/2

2 = -2+x₂/2

4 = -2 + x₂

x₂ = 6

Similarly;

Substitute

-2 = (1+y₂)/2

-4 = 1+x₂/2

-8 = 1 + y₂

y₂ = -9

Hence the coordinate of point B from the given coordinates is (6, -9)

Step-by-step explanation:

If the system has infinitely many solutions, then

     [tex]\sf \boxed{\bf \dfrac{a_1}{b_1}= \dfrac{a_2}{b_2}= \dfrac{c_1}{c_2}}[/tex]

    ax + by = 12  ⇒ a₁ = a  ; b₁ = b ; c₁ = 12

    2x + 8y =60  ⇒ a₂ = 2  ; b₂ = 8 ; c₂ = 60

[tex]\sf \dfrac{a}{2}= \dfrac{b}{8}= \dfrac{12}{60}\\\\\\ \dfrac{a}{2}= \dfrac{12}{60}\\\\a = \dfrac{12}{60}*2\\\\a = \dfrac{2}{5}[/tex]

                         [tex]\sf \dfrac{b}{8}= \dfrac{12}{60}\\\\ b = \dfrac{12}{60}*8\\\\b = \dfrac{8}{5}\\[/tex]

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

The function of the graph is,

y = 2x² + ax + b

The graph intersects the x-axis at the points (-7/2, 0) and (2, 0).

Now,

Since, The graph intersects the x-axis at the points (-7/2, 0) and (2, 0).

Hence, The points must satisfy the graph of the function.

So, Points (-7/2, 0) and (2, 0) are satisfy the function y = 2x² + ax + b.

When point (-7/2, 0) satisfy the function y = 2x² + ax + b

Then,

0 = 2 × (-7/2)² + a × (-7/2) + b

0 = 49/2 - 7a/2 + b

7a/2 - b = 49/2 .... (i)

And, When point (2, 0) satisfy the function y = 2x² + ax + b

Then,

0 = 2 × (2)² + a×2 + b

2a + b = -8    .... (ii)

Add equation (i) and (ii) we get;

7a/2 - b + 2a - b = 49/2 + (-8)

11a/2 = 33/2

11a = 33

a = 3

And, 2a + b = -8

2 × 3 + b = -8

b = -8 - 6

b = -14

Hence, The value of a is 3.

The value of b is -14.

Answer:

x = -7

Step-by-step explanation:

Solve for x:

5 - 4 x + 3 (3 x + 5) = -15

3 (3 x + 5) = 9 x + 15:

(9 x + 15) - 4 x + 5 = -15

Grouping like terms, 9 x - 4 x + 5 + 15 = (-4 x + 9 x) + (5 + 15):

((-4 x + 9 x) + (5 + 15)) = -15

9 x - 4 x = 5 x:

5 x + (5 + 15) = -15

5 + 15 = 20:

5 x + 20 = -15

Subtract 20 from both sides:

5 x + (20 - 20) = -20 - 15

20 - 20 = 0:

5 x = -20 - 15

-20 - 15 = -35:

5 x = -35

Divide both sides of 5 x = -35 by 5:

(5 x)/5 = (-35)/5

5/5 = 1:

x = (-35)/5

The gcd of -35 and 5 is 5, so (-35)/5 = (5 (-7))/(5×1) = 5/5×-7 = -7:

Answer: x = -7

The next arrival in the sequence 3:00 pm, 12:30 pm, 10:00 pm,... is 7:30 A.M.

The given sequence is 3:00 pm, 12:30 pm, 10:00 pm,...

Let us first find the difference between the arrivals from the given sequence

3:00 pm - 12:30 pm = 2:30

12:30 pm - 10:00 pm = 2:30

Since, each arrival time is 2 hours and 30 minutes prior to the previous arrival time.

Therefore, the next arrival is:

10:00 pm - 2:30 = 7:30 am
