Solve: a no solution b infinitely many solutions

Mathematics
1 answer:
Dmitry_Shevchenko [17]3 years ago
7 0

Answer: a

no solution

Step-by-step explanation:

Solve by substitution:

1) Solve x=2y+4 for x:

x=2y+4

2) Substitute 2y+4 for x in 2y=x-6:

2y=x-6

2y=2y+4-6

3) Simplify both sides of the equation:

2y=2y-2

4) Add -2y to both sides of the equation:

2y+-2y=2y-2+-2y

5) Simplify both sides of the equation:

0=-2

Therefore, there are no solutions to the system of equations.

Solve by elimination:

You can't solve this system of equations by elimination

Solve by graphing:

The equations are parallel to each other, therefore they never cross, so, there are no solutions.

Width: 4 feet

Step-by-step explanation:

Length: L

Width: 2L - 8

2L + 2(2L - 8) = 20

2L + 4L - 16 = 20

6L = 36

L = 36/6

L = 6

W= 2(6)-8 = 4

True or false? To begin an indirect proof, you assume the converse of what you intend to prove is true.
djyliett [7]

Answer:

The statement is false.

Step-by-step explanation:

To begin an indirect proof, you assume the converse of what you intend to prove is true. This is false.

Rather the correct answer is that to begin an indirect proof, you assume the inverse of what you intend to prove is true.

The converse can be either true or false, depending on what the original statement is, so assuming the converse is pointless.

Find the Area of the figure below, composed of a rectangle with two semicircles removed. Round to the nearest tenths place.
Allisa [31]

Answer:

21.8

Step-by-step explanation:

hii so basically first we find the area of the 9 by 8 and subtract the area of the semicircles.

area of circles are πr^2, so in this situation

π4^2 which is 16π.

with this, the semicircle which is half a circle would give us

16π/2 which is 8π.

but then, we have two semicircles removed so we would have as an answer:

(9*8)-8π+8π

72-16π

then you would have to round so

16π is around 50.2

so 72-50.2 is 21.8

i hope this helped you <33
