Answer:

<CPB

Step-by-step explanation:

Because <APE= right angle

<APC= Obtuse angle

<CPE= Obtuse Angle.

Also, <CPB because its the only angle below 90 degrees and an acute angle must be below 90 degrees.

100 Points! What are the classifications of each system?

alexdok [17]

Answer:

Part 1) Is a inconsistent system

Part 2) Is a consistent independent system

Part 3) Is a consistent dependent system

see the attached figure

Step-by-step explanation:

we know that

If a system has at least one solution, it is said to be consistent .

If a consistent system has exactly one solution, it is independent .

If a consistent system has an infinite number of solutions, it is dependent

If a system not have solution, it is said to be inconsistent

Part 1) we have

$x+5y=-2\\x+5y=4$

This system of linear equations has two parallel lines (their slopes are equal) with different y-intercept

The lines don't intersect

The system has no solution

therefore

Is a inconsistent system

Part 2) we have

$y=3x+4\\-2x+y=4$

we know that

If two lines have different slopes, then the lines intersect at one point and the system of equations has one solution

In this problem, the lines have different slopes (m=3 and m=2)

The lines intersect at one point

The system has one solution

therefore

Is a consistent independent system

Part 3) we have

$3x+y=4$ ----> equation A

$-6x-2y=-8$ ----> equation B

Multiply equation A by -2 both sides

$-2(3x+y)=-2(4)$

$-6x-2y=-8$ ----> equation C

Compare equation B and equation C

Are identical lines

The system has infinity solutions

therefore

Is a consistent dependent system

If x is equal to -6 which equality is true

Papessa [141]

Answer:

-5 - 3x > 10

Step-by-step explanation:

x = -6

Plug in the x value for each inequality:

-5 - 3(-6) > 10

-5 + 18 > 10

13 > 10

True

-3 - 5(-6) < -14

-3 + 30 < -14

27 < -14

False

1 - 2(-6) > 13

1 + 12 > 13

13 > 13

False

2 - (-6) < -3

2 + 6 < -3

8 < -3

False

Only one of these is true; that is the answer.

PLEASE HELP IVE POSTED THIS AND NO RESPONSE YET ! It’s an exam

solmaris [256]

Answer: 262,000? I'm just guessing

Step-by-step explanation:

one product costs $14 to produce. It is mentioned that you need to produce 14,000 products or items, so you multiply 14 by 14,000 to know the total cost of producing 14,000 items or products, the answer is 196,000, remember there is also a start-up cost of 66,000. So you must add 196,000 to 66,000 which leads to 262,000. Hope this helps :)

Do you guys the answer for number 3

ohaa [14]

Answer:

the answer is L. or the last answer

Step-by-step explanation:

you have to find the total area of the place first...

which is 21*17=357

then subtract the inner area (white area) which is

14*20=280

do 357-280 to get the remaining area and the answer is 77ft^2

hope this helps.. vote, comment, thanks, and maybe mark me brainliest lol idk
