Pls help, I cannot do this and it is due 8-28-20

Answer:

Step-by-step explanation:

The slope of a line between two points can be found by using the formula

[tex]m = \frac{y2 - y1}{x2 - x1} [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(5,–10) and (-3,-10)

Their slope is

[tex]m = \frac{ - 10 + 10}{ - 3 - 5} = \frac{0}{ - 8} = 0[/tex]

We have the final answer as

Slope = 0

Hope this helps you

Answer:

Step-by-step explanation:

[tex] \sf{x + 3(2x - 5) = 6}[/tex]

Distribute 3 through the parentheses

⇒[tex] \sf{x + 6x - 15 = 6}[/tex]

Collect like terms

⇒[tex] \sf{7x - 15 = 6}[/tex]

Move constant to right hand side and change it's sign

⇒[tex] \sf{7x = 6 + 15}[/tex]

Add the numbers

⇒[tex] \sf{7x = 21}[/tex]

Divide both sides of the equation by 7

⇒[tex] \sf{ \frac{7x}{7} = \frac{21}{7} }[/tex]

Calculate

⇒[tex] \sf{x = 3}[/tex]

Hope I helped!

Best regards!

The value of x is 3 for the equation x + 3(2x-5) = 6.

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

The given equation is x + 3(2x-5) = 6

x plus three times of two times of x minus five equal to six.

We need to find the value of x.

x + 3(2x-5) = 6

Apply distributive property.

x+6x-15=6

7x-15=6

Add 15 on both sides

7x=6+15

7x=21

Divide both sides by 7

x=3

Hence, the value of x is 3 for the equation x + 3(2x-5) = 6.

Answer:

Proportional: second and third, non-proportional: first and fourth

Step-by-step explanation:

Proportional relationships are linear functions that pass through the origin. Using this definition, we can conclude that the proportional relationships are the second and third options whereas the non-proportional relationships are the first and fourth options.

Answer:

proportional relationship: the second one and the third one the first and the fourth one

Non-proportional relationship: the first and the fourth one

Step-by-step explanation:

Like the first person said, a proportional relationship is when a linear line passes thru the origin, which is known as (0,0), so the second and the third are the only ones that do that, plus they have a y-intercept of a 0 and the others don't.

Answer: The last one  15[tex]g^{2}[/tex] +15g

Answer:

46 and 64

Step-by-step explanation:

4 + 6 = 10

6 + 4 = 10

64 - 46 = 18

b=7×10(opposite angle of parallelogram)

b=70

3x+10+b=180(cointerior angles)

3x=10

x=33.33

a+70=180(cointerior angles)

a=110

Answer:

x = 4

y = -3

Step-by-step explanation:

We can use substitution, elimination, or graphically.

Step 1: Rearrange first equation

2x + 4y = -4

2x = -4 - 4y

x = -2 - 2y

Step 2: Rewrite systems of equations

x = -2 - 2y

3x + 5y = -3

Step 3: Substitution

3(-2 - 2y) + 5y = -3

-6 - 6y + 5y = -3

-6 - y = -3

-y = 3

y = -3

Step 4: Find x using y

2x + 4(-3) = -4

2x - 12 = -4

2x = 8

x = 4

Graphically:

Use a graphing calc and analyze where the 2 lines intersect.

Answer:

Step-by-step explanation:

Answer:

No.

Step-by-step explanation:

A function must past the Vertical Line Test. We know that our equation x² + y² = 5 is a circle, and so some x-values have the same y-values, etc. Since not every x-value has its own y-value, our equation is not a function.

We can see this using a graph:

Since the vertical line test passes 2 points with the same x-value, it is not a function.

Answer:

2x-3=-21.

2x=-21+3.

2x=-18.

x=-18/2.

x= -9.

Answer:

[tex]\Huge \boxed{2x-3=-21}[/tex]

Step-by-step explanation:

Let the number be x.

The difference of two values is the result from subtracting them.

[tex]2x-3=-21[/tex]

Add 3 to both sides.

[tex]2x=-18[/tex]

Divide both sides by 2.

[tex]x=-9[/tex]

The number is -9.

Answer:

Step-by-step explanation:

To solve the equation

(2x - 1) + (4x + 9) = 32

First of all remove the parenthesis

That's

2x - 1 + 4x + 9 = 32

Simplify

We have

6x - 8 = 32

Add 8 to both sides

Thats

6x - 8 + 8 = 32 + 8

6x = 40

Divide both sides by 6

That's

[tex] \frac{6x}{6} = \frac{40}{6} [/tex]

We have the final answer as

[tex]x = \frac{40}{6} [/tex]

Answer:

  D) 10000 feet

Step-by-step explanation:

We are told that for some actual altitude, the reading is ...

  30,000 ft = (1 -25%)altitude = 0.75×altitude

Multiplying by 4/3, we have ...

  (4/3)(30,000 ft) = altitude = 40,000 ft

To get to 30,000 ft, the plane must descend ...

  40,000 ft -30,000 ft = 10,000 ft

Answer: 10 treats per seal, and there are 5 treats left.

Step-by-step explanation:

The zookeeper has 85 treats, and want to divide them into seals, in such a way that the treats left is minimized,

Then we want to find the multiple of  that is closer to 85 (from below)

We know that: 8*10 = 80 is a multiple of 8, and the next one is:

8*11 = 88, but this is larger than 85, so we discard this option.

Then we will divide 80 treats into 8 seals, and we will have:

85 - 80 = 5 treats left.

Then each one of the 8 seals gets:

80/8 =  10 treats.

Answer:

Step-by-step explanation:

Since there are 7 students in a classroom to fill a front row containing 3 seats, we will apply the combination rule since we are to select 3 students from the total number of 7 students in the class.

In combination, if r objects are to be selected from a pool of n objects, this can be done in nCr number of ways.

nCr = n!/(n-r!)r!

Selecting 3 students from 7 students to fill the seats can therefore be done in 7C3 number of ways.

7C3 = 7!/(7-3)!3!

7C3 = 7!/(4)!3!

7C3 = 7*6*5*4!/4!*3*2

7C3 = 7*6*5/6

7C3 = 7*5

7C3 = 35

Hence there are 35 different ways that the student can sit in the front assuming there are no empty seats.

Answer:

  11,180

Step-by-step explanation:

The usual assumption for organic growth is that it is exponential. Here, the number increased by a factor of 1000/200 = 5 in 8 hours. For t in hours, a model for population might be ...

  b = (initial value)·(growth factor)^(t/(period of growth))

  b = 200(5^(t/8))

Using t = 20, the predicted population is ...

  b = 200(5^(20/8)) = 200·5^2.5 ≈ 11,180

There might be about 11,180 bacteria in 20 hours.
