The value of x is 40 degree and y is 105 degree.

Linear pair of angles are formed when two lines intersect each other at a single point. The angles are said to be linear if they are adjacent to each other after the intersection of the two lines. The sum of angles of a linear pair is always equal to 180°.

2x - 5 + 75=180

2x+70=180

x= 110/2

x= 55 degree.

Now, y=  2x-5 = 2(55)-5 = 110- 5 = 105  (Vertically opposite angle)

Hence, the value of x is 40 degree and y is 105 degree.

Answer:

Graph D

Step-by-step explanation:

Graphs that represent functions have to correlate with each other in some way so it has to be either linear or non-linear so Graphs B and C are out of the question

To find the graph that represents a function you do the vertical line test which is when you draw a line though the x-axis and as soon as two or more points are on the same line it is no longer a function so graph a is out

By proess of elimination the function is graph D

The required solution of the given quadratic equation is [tex]{\displaystyle x={\frac {2\ - {\sqrt {(-32)}}}{2}}[/tex] and  [tex]{\displaystyle x={\frac {2\ + {\sqrt {(-32)}}}{2}}[/tex]

In elementary algebra, the quadratic formula is a formula that provides the solution(s) to a quadratic equation.

Given a general quadratic equation of the form

ax^2 + bx + c = 0

with x representing an unknown, with a, b and c representing constants, and with a ≠ 0, the quadratic formula is:

[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]

and,

Now the given quadratic equation is,

x^2 - 2x = - 9

or,  x^2 - 2x + 9 = 0

here, a = 1

b = -2

c = 9

Thus quadratic formula is given as,

[tex]{\displaystyle x={\frac {-b\pm {\sqrt {b^{2}-4ac}}}{2a}}[/tex]

[tex]{\displaystyle x={\frac {-(-2)\pm {\sqrt {(-2)^{2}-4*1*9}}}{2*1}}[/tex]

[tex]{\displaystyle x={\frac {2\pm {\sqrt {4-36}}}{2}}[/tex]

[tex]{\displaystyle x={\frac {2\pm {\sqrt {(-32)}}}{2}}[/tex]

Thus,we get,

[tex]{\displaystyle x={\frac {2\ - {\sqrt {(-32)}}}{2}}[/tex]

[tex]{\displaystyle x={\frac {2\ + {\sqrt {(-32)}}}{2}}[/tex]

Thus,the required solution of the given quadratic equation is [tex]{\displaystyle x={\frac {2\ - {\sqrt {(-32)}}}{2}}[/tex] and  [tex]{\displaystyle x={\frac {2\ + {\sqrt {(-32)}}}{2}}[/tex]

Answer: 69

Step-by-step explanation: 59+10=69

The trucks arrive 10 minutes after the first call. The first and the second truck travel for 5 miles and 8 miles respectively.

In a time difference of 3 minutes, two fire trucks are called.

The average speed of the first truck is 30 miles per hour.

The average speed of the second truck is 60 miles per hour.

The trucks totally travel for 12 miles and arrive at the same time.

Let d be the number of miles the first truck drove.

Let t be the number of minutes it took the first truck to travel.

Now, Convert 30 miles per hour to a half mile per minute and 60 miles per hour to a mile per minute as we are measuring time in minutes.

For the first truck:

d = 0.5t

The second truck traveled 12 - d miles if the first truck traveled d miles. In the event where the first truck traveled for t minutes and was called 3 minutes later, the second vehicle would have gone for t - 3 minutes.

For the second truck:

12 - d = t - 3

Therefore,

12 - 0.5t = t - 3

15 = 1.5t

t = 15 / 1.5

t = 10 minutes

The trucks arrive after 10 minutes after the first call.

Then,

d = 0.5t = 0.5(10) = 5 miles

And 12 - d = 12 - 5 = 8 miles.

Hence, the first truck traveled for 5 miles and the second truck traveled for 8 miles.

You can walk 4/5 of a mile in 1/4 of an hour (15 minutes). How far can you walk in an hour?

If you can walk 4/5 of a mile in 1/4 of an hour the equation would be:

4/5x = 1/4

multiply both sides by 4:

4(4/5x) = 4(1/4)

The hour hand that goes through 3 right angles and starts from 7 will stop at 4.

We can assume that the numbers in a clock are positioned in a circle. The angle in a circle is 360⁰, while the numbers in a clock is 12.

Hence, from each clock number to its consecutive number, the hour hand must travel 30⁰ as shown in the attached picture.

A right angle is equal to 90⁰. This is equal to 3 ⨉ 30⁰. In other words, to travel  90⁰ means to travel 3 hours.

3 right angles =  3 ⨉ 90⁰

                      = 3 ⨉ 3 hours

                      = 9 hours.

Thus, the hour hand will go to:

7 + 9 = 16

16 is equal to number 4 in a clock number.

Conclusion: If the hour hand start from 7, it will stop at clock number 4.

Answer:

(x, y) = (x 7/2, -3/4x m) x € R

The equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m

The equation is given as

2/(7 - m) = 4/(m - 5) - m/(7 -m)

Take the like terms of the above equation

So, we have

m/(7 -m) + 2/(7 - m) = 4/(m - 5)

Evaluate the like terms in the above equation

So, we have

(m + 2)/(7 -m) = 4/(m - 5)

Cross multiply the above equation

So, we have

m^2 + 2m - 5m - 10 = 28 - 4m

Evaluate the like terms

m^2 + m + 18 = 0

Using a graphing tool, we have no solution for m

Hence, the equation given as 2/(7 - m) = 4/(m - 5) - m/(7 -m) has no real solution for m

Given, that the sum of two sides of a triangle is greater than or equal to the third side.

considering 2 cm, 3 cm, 4 cm

Let the two sides be 2 cm and 3 cm

Let the third side be 4 cm

Now, sum of two sides = 2 + 3 = 5 cm

So, 5 > 4

Therefore, the given statement is false.

A triangle's total internal angles are always equal to 180 degrees. This is referred to as the triangle's angle sum property. There are three sides and three angles in every triangle, some of which may be the same. Triangles are three-sided shapes. The various kinds of triangles go by various names. The size of the angles and the length of the sides determine the type of triangle (corners). Equilateral, isosceles, and scalene triangles are the three varieties of triangles based on the length of the sides.

Nikki alone can do work to write the problem in 43 hours, and Kelly can work in 39 hours.

What are work and time?

The joule (J), sometimes known as the Newton meter (N m), is the SI unit for work. When an object is moved across a distance of 1 m with 1 N of force, one joule is equal to the amount of work that is accomplished.

Work and time are proportionate to one another. Because of this, more work can be done with more time, and vice versa.

Nikki can do the part of this problem in 1 hour = 1/x

And, Kelly can do the part of this work in 1 hour = 1/(x - 4)

So, Nikki and Kelly both can do this work in 1 hour = (1/x) + [1/(x - 4)] = 120

        = 40x - 80

                                                  = x² - 4x

        = x = 43, 2

Hence,

Nikki alone can do work to write the problem in 43 hours, and Kelly can work in 39 hours.
