Need to find angle z please help. Angle x and y are 56 degrees.

Answer:

27 ) x = 15°,

28 ) x = 18°

Step-by-step explanation:

27 ) We are given angle measures of 85 degrees, consecutively 6x + 5, each forming a linear pair;

85 + ( 6x + 5 ) = 180 ⇒ by definition of linear pair we have two measures of angles that add to 180°,

85 + ( 6x + 5 ) = 180 ⇒ take out ( ),

85 + 6x + 5 = 180 ⇒ combine like terms,

90 + 6x = 180 ⇒ subtract 90 from either side of equation,

6x = 90 ⇒ divide 6 on either side of equation,

Solution; x = 15°

28 ) We are given angle measures of 110 degrees, consecutively 3x + 16, each forming a linear pair;

110 + ( 3x + 16 ) = 180 ⇒ by definition of linear pair we have two measures of angles that add to 180°,

110 + ( 3x + 16 ) = 180 ⇒ take out ( ),

110 + 3x + 16 = 180 ⇒ combine like terms,

126 + 3x = 180 ⇒ subtract 126 from either side of equation,

3x = 54 ⇒ divide 6 on either side of equation,

Solution; x = 18°

Answer: The tax rate would get higher the more money you make

Answer

7m x 5m = 35, then multiply by 100, so then the answer is 3,500

Step-by-step explanation:

The number of tiles that can fit in the living room is 7000.

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

As per the given dimension of the living room,

7m by 5m

Area = 7 x 5 = 35 m²

Area of one tile = 50 cm² = 0.005m²

With this surface area the number of tiles that can be fit,

35/0.005 = 35000/5 = 7000

Hence "The number of tiles that can fit in the living room is 7000".

Step-by-step explanation: Plato answer

The three programs or services are supported by taxes are fire departments, Medicare and public education

A tax is a sum of money that people pay to the government for the services provided by the government.

The three programs or services that are supported by taxes are:

Fire departments: Taxes are used to fund fire departments that provide emergency services such as firefighting, rescue, and medical assistance.

Medicare: Taxes are used to fund Medicare, a federal health insurance program for people who are 65 or older, certain younger people with disabilities, and people with End-Stage Renal Disease.

Public education: Taxes are used to fund public education, including elementary, middle, and high schools, as well as public colleges and universities.

Shopping malls and theaters are not typically supported by taxes.

They are usually privately owned and funded by their owners.

Hence, the three programs or services are supported by taxes are fire departments, Medicare and public education

Answer: a = -5

Step-by-step explanation:

-3 (9a+2)=129

-27a -6 = 129

-27a = 129+6

-27a = 135

a = -135/27

Answer:

a= -5

Step-by-step explanation:

To solve the equation, we want to find out what a is. In order to do this, we have to get a by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

-3(9a+2)=129

-3 is being multiplied by 9a+2. The opposite of multiplication is division, so divide both sides by -3.

-3(9a+2)/-3=129/-3

9a+2=129/-3

9a+2=-43

2 is being added on to 9a. The opposite of addition is subtraction, so subtract 2 from both sides.

9a+2-2= -43-2

9a= -43-2

9a= -45

a is being multiplied by 9. The opposite of multiplication is division, so divide both sides by 9.

9a/9= -45/9

a= -45/9

a=-5

Answer:

6

Step-by-step explanation:

To solve this, you need to have your equation in slope-intercept form.  This is y=mx+b, where m is the slope and b is the y-intercept.

y - 5 = 6(x - 4)

y - 5 = 6x - 24

y = 6x - 19

The slope, m, is equal to 6.

Answer:

a = -5

b = 2

Step-by-step explanation:

a+b=-3

a-b= -7              +

2a  = -10

a = -10/2

a = -5

a + b = -3

-5 + b = -3

b = -3 + 5

b = 2

Answer:

Answer:

3/5

Step-by-step explanation:

First one   18^2 - 4(-1)(81)  > 0    so no repeated root

Second one     (-3)^2  - 4(3) (-168)  >  0    so no repeated root

Third one   (-4) - (4) (1) (-4)  > 0      so no repeated root

Fourth one  (-30)^2  - 4(25) (9)   =  900 - 100(9)  =  0      repeated root

Note  this factors  as  (5x - 3)^2  

(5x - 3)^2  = 0     take both roots

5x - 3  = 0

5x  = 3

x  =  3/5   = repeated root

The quadratic expression [tex]25x^{2} -30x+9[/tex] has repeated root and the repeated root is 3/5

Let, [tex]ax^{2} +bx+c=0[/tex] is a quadratic.

Then the expression ([tex]b^{2}-4ac[/tex]) is called the discriminant of the quadratic.

If  [tex]b^{2}-4ac[/tex] = 0 then we can say that the quadratic has a repeated real root.

The discriminant of [tex]-x^{2} +18x+81[/tex] is,

[tex]b^{2}-4ac[/tex] = [tex]18^{2}-4(-1)(81)[/tex] = 324+324=648 > 0

So, This quadratic has no repeated root.

The discriminant of [tex]3x^{2} -3x-168[/tex] is,

[tex]b^{2}-4ac[/tex] = [tex](-3)^{2}-4(3)(-168)[/tex] = 9+2016 = 2025 > 0

So, This quadratic has no repeated root.

The discriminant of [tex]x^{2} -4x-4[/tex] is,

[tex]b^{2}-4ac[/tex] = [tex](-4)^{2}-4(1)(-4)[/tex] = 16+16 = 32 > 0

So, This quadratic has no repeated root.

The discriminant of [tex]25x^{2} -30x+9[/tex] is,

[tex]b^{2}-4ac[/tex] = [tex](-30)^{2} -4(25)(9)[/tex] = 900-900 = 0

So, This quadratic has repeated root.

The discriminant of [tex]x^{2} -14x+24[/tex] is,

[tex]b^{2}-4ac[/tex] = [tex](-14)^{2}-4(1)(24)[/tex] = 196-96 = 100 > 0

So, This quadratic has no repeated root.

The equation [tex]25x^{2} -30x+9[/tex] = 0 has repeated root.

Simplifying the equation we get,

[tex]25x^{2} -30x+9[/tex] = 0

⇒ [tex](5x)^{2}-2(5x)(3)+3^{2}[/tex] = 0

⇒ [tex](5x-3)^{2}[/tex] = 0

⇒ 5x-3 = 0

⇒ 5x = 3

⇒ x = 3/5

The repeated root is 3/5.

Answer: 28 degrees farenheit

Step-by-step explanation: add 22 and 6 for the total of how many degrees -6 is from 22.

If the  temperature at dawn is -6°F but by noon it is 22°F.Then 28°F  is the difference in temperatures

Two or more expressions with an Equal sign is called as Equation.

The temperature at dawn is -6°F

The temperature at dawn in afternoon is 22°F.

We need to find the difference in temperatures.

Difference is nothing but subtracting one number with another number.

Now subtract  -6°F from 22°F.

22°F-(-6°F)

Twenty two degree fahrenheit plus six degree fahrenheit

22°F+6°F

If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.

A linear equation is in the form:

y = mx + b

Where m is the rate of change and b is the intial value of y.

Let x represents the activity level and y represents the number of meals eaten. Given that:

y = 0.23x + 4.1

For an activity level of 9 (x = 9):

y = 0.23(9) + 4.1 = 6.17

2. the slope is -10 and y-intercept is 1

Step-by-step explanation:

hope this helps!

Answer:

B. The slope is –10, and the y-intercept is 1.

Step-by-step explanation:

Our equation is y = -10x + 1. Notice that this is of the form y = mx + b, which is called the slope-intercept form because it literally gives us the slope and y-intercept in the equation:

- m: this is the slope value

- b: this is the y-intercept

Here, m = -10, which means the slope is -10. Also, b = 1, so the y-intercept is 1.

Thus, the answer is B.
