When graphed, a system of equations forms two lines that overlap completely. What is the solution set of this system of equations? Explain why it has this solution set.

Answer:

NaruSaku for sureee

Answer:

0.6b - 3c

Step-by-step explanation:

Multiply 0.2 and 3b

0.2 x 3b = 0.6b

Then multiply 0.2 and 15c

0.2 x 15c = 3c

We can't add these, 3c and 6b because they have different letters.

different letter vs. different letter =

don't add

different letter vs. normal number like 5 =

dont add

same letter vs. same letter =

add

normal number vs. normal number =

add

This all goes the same for dividing, subtracting, and multiplying

I hope this helped! :)

|60| = 60, and 60 is the same as 60

Answer:

r=4 d=8 a = 16π c = 8π

d=6 r=3 a=9π c=6π

a=36π r=6 d=12 c=12π

Answer: x = 5, y = 2; Solution = (5, 2)

Step-by-step explanation:

Substitution

2x + y = 12

x + 2y = 9

x + 2y = 9

Subtract 2y from both sides

x = 9 - 2y

Now, substitute x for (9 - 2y) in the first equation

2x + y = 12

2 (9 - 2y) + y = 12

Distribute 2

18 - 4y + y = 12

18 - 3y = 12

Subtract 18 from both sides

-3y = -6

Divide both sides by -3

y = 2

Now to find x, substitute 2 for y in (x = 9 - 2y)

x = 9 - 2y

x = 9 - 2(2)

x = 9 - 4

x = 5

Solution: (5, 2)

Elimination

2x + y = 12

x + 2y = 9

Multiply the second equation by -2 to find y

2x + y = 12

(x + 2y = 9) -2

2x + y = 12

-2x - 4y = -18

Add both equations

2x and -2x are cancelled out

You get:

-3y = -6

Divide both sides by -3

y = 2

Substitute 2 for y in any of the equations to find x

I chose x + 2y = 9

x + 2y = 9

x + 2 (2) = 9

x + 4 = 9

Subtract both sides by 4

x = 5

Solution = (5, 2)

Btw you can use any of these methods, I used both so you could know that you get the same answer no matter the method.

Hope I helped!

The function would be y = 0.45x, x being the number of seconds, y being the items he can ring up.

For example (this is an example only to show how this equation works), if we were looking at how many items the cashier can ring in 5 seconds, we would make the equation y = 0.45(5), and with multiplication, we can find that they would ring 2.25 items ( y = 2.25 )

Answer:

As sunlight passes through the atmosphere, it heats up the surface of Venus. Most of this heat cannot escape back into space because it is blocked by the very thick atmosphere of Venus. The heat becomes trapped and builds up to extremely high temperatures

Answer:

Equation- s + 456 = 437 (I'm not completely sure if this is what your wanting but it is possible to solve the problem with this equation. if this isn't what you need I can write another)

Step-by-step explanation:

s represents the starting height.

s + 456 = 437

first subtract 456 from either side, 437 - 456 = -19.

s = -19 (I'm not sure if this is correct it's been a few months since I've used variables for equations but I tried)

Answer:

16 ft

Step-by-step explanation:

We start by converting 1yd to ft,

1yd = 3ft

So in the smaller triangle, we have 3ft, 4.5ft. Using Sine, Cos, and Tan rule. We know that

TanΦ = opposite / adjacent

TanΦ = 3ft / 4.5ft

TanΦ = 0.667

Φ = Tan^-1 0.6

Φ = 33.69

This means that the angle of elevation is 33.69°

Using this angle, and the same tan rule again, we gave

Tan 33.69 = opp/24

0.667 = opp/24

opp = 24 * 0.667

opp = 16 ft

answer is b=16

hope that helped loll
