MARKING BRAINLIEST PLZ HELP! You are given the following five lines:
Line 1: y=-2x + 9
Line 2: y= 1/2x + 1
Line 3: y= 2x + 2
Line 4: 6x - 3y = 6
Line 5: 4x + 2y = 4

Part A: Which two lines could be used to create a system of equations that has no solution? Explain your answer

Part B: Which two lines could be used to create a system of equations that has many solutions? Explain your answer

Part C: Which two lines could be used to create a system of equations that has one solution? Explain your answer​

Answer:

y = -3x - 5

Step-by-step explanation:

-2y = 6x + 10

divide both sides by -2

y = -3x - 5

2h*0.2

2h is h doubled

20% becomes 0.2

Answer:

I can't solve this completely for you, but I'll help you figure it out.

Step-by-step explanation:

All you need to do is choose a number to plug in for x, I'd start with zero and work my way up. Do this for all equations to solve for solutions to your problem.

Answer:

-1/6

Step-by-step explanation:

To get the slope we need the equation in the form y=mx+c, and m is the slope.

2x+12y=192

12y = -2x + 192

y = -2/12 x + 16

-2/12 is the slope but this can be simplified to -1/6

Answer:

Option A

The system of inequalities

x + y ≤ 200

4x + 3y ≤ 750

Step-by-step explanation:

Let the

Number of Adults = x

Number of campers = y

A summer camp cookout is planned for the campers and their families.

There is room for 200 people.

x + y ≤ 200

Each adult costs $4, and and each camper costs $3. There is a maximum budget of $750.

Maximum means the total cost is equal to or less than $750

$4 × x + $3 × y ≤ $750

4x + 3y ≤ 750

The system of inequalities

x + y ≤ 200

4x + 3y ≤ 750

Option A is correct

Answer:

d

Step-by-step explanation:

Answer:

D. x=6

Step-by-step explanation:

4x-9=15

Add 9 on both sides

Now the equation will be

4x=24

Divide 4 on both sides which will end up giving you

x=6

Help with what?

Step-by-step explanation:

Answer:

£53

Step-by-step explanation:

According to the scenario, the computation of the given data are as follows,

1 turkish Lira = £0.17

Now convert £312 into turkish lira

So it can be calculated below:

= £0.17 × £312

= £53.04

After converting into turkish lira, it is £53

Answer:

CD = 25 ft

Step-by-step explanation:

[tex] \triangle CDE \sim \triangle RST[/tex]

[tex]\therefore \frac{CD}{20}=\frac{40}{32}[/tex]

(Corresponding sides of similar triangles are in proportion)

[tex]\therefore \frac{CD}{20}=\frac{5}{4}[/tex]

[tex]\therefore CD = \frac{5}{\cancel 4}\times \cancel {20} \:\:\blue{\bold{5}} [/tex]

[tex]\therefore CD = 5\times 5[/tex]

[tex]\therefore CD = 25\: ft[/tex]

Answer:

CD = 25 ft

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{CD}{RS}[/tex] = [tex]\frac{CE}{RT}[/tex] , substitute values

[tex]\frac{CD}{20}[/tex] = [tex]\frac{40}{32}[/tex]  ( cross- multiply )

32CD = 800 ( divide both sides by 32 )

CD = 25

Answer:

C) 8 : 14

Step-by-step explanation:

From the Question, we have

Six butterfly stroke laps

Eight freestyle Laps.

Total number of laps = (6 + 8)laps

= 14 laps

Hence,

The ratio of freestyle laps to total laps is:

Freestyle laps : Total laps

= 8 : 14

Option C is correct.

Answer:

question 2 answer. option. a. 55

Step-by-step explanation:

diameter of semi circular window is 35 inches

the radius is 17.5

perimeter of semicircular window =pie x radius

= 22 /7 ×17.5

=55 inches

The height of the triangle is 0.00625.The correct option is D

A density graph must have an area under it equal to 1. The range of speeds in this problem, 320-0 = 320, is the base of the density graph, which is shaped like a triangle. By multiplying the base by half of the triangle's height, we can determine the density graph's area.

Let h represent the triangle's height. The triangle's area is then:

1 = (1/2)320h

calculating h:

h = 1 / (320/2) = 0.00625

Therefore, option D is appropriate because the triangle's height is 0.00625.
