What is the solution to the system shown below y=2x-1. Y=2x+3 A (0,0). B(1,-3) C(-1,3). D no solution

1 answer:

5 0

We have that
y=2x-1
and
Y=2x+3
the two lines are parallel
because the slopes are the same
m=2

we know that
If two lines are parallel, then they will never intersect

therefore
the answer is the option
D no solution

Create a graph showing the equations y=1/4x and y=1/4x-5. Explain how the graphs are the same and how their different

Eduardwww [97]

Answer:{y=1/4x-5 [-10, 10, -5, 5]}

Step-by-step explanation:

The

−

part says that the

-intercept of this line is

−

. The

-intercept is the point at which a line crosses the

axis. Therefore,

is always

for the

intercept.

The

is implying that the slope or the gradient (same thing) of this line is

. Therefore,

can be expanded to

−

Since we already know that the point

{

−

}

lies on this line, let's substitute

for

and

for

−

Now, if you choose a point for

, you can simply work out

. For example, let's say I chose

−

Now, what makes

when divided by

−

? The answer is

−

Therefore, we need

−

on the numerator. We already have

−

, and

is negative, so the number

−

fits. So the coordinates for the 2nd point is

{

−

}

−

Now, with the points we have,

{

−

}

and

{

−

}

, we can graph this by plotting the points and joining them.

You should get this graph{y=1/4x-5 [-10, 10, -5, 5]}

Ali bought a music system for rs 6375.00 and spent rs 75.00 on transportation . He sold it for 6400.00 . Find his profit or loss

pentagon [3]

Answer: Loss percent = 0.775%

Step-by-step explanation:

Here,

Total cost = Purchasing price + transportation

⇒ Total cost = 6375 + 75

⇒ Total cost = $ 6450

Selling price = $ 6400

Total cost > Selling price, hence it is a loss.

Loss percent formula :

$Loss\% =\dfrac{\text{Loss}}{Total\ cost}\times100\\\\=\dfrac{Total\ cost - Selling price}{Total \ cost}\times100\\\\=\dfrac{6450-6400}{6450}\times100\\\\=\dfrac{50}{6450}\times100=0.775\%$

Hence, Loss percent = 0.775%

How can you describe the solution 16x^2-8x+1=0

Vanyuwa [196]

(4x-1)(4x-1)=0
4x-1=0
4x=1
x=1/4

I would describe it as having a multiplicity of 2

What is the length of side x? If necessary, round your answer to two decimal places. 19 12

Valentin [98]

Answer:

D. 14.73

Step-by-step explanation:

According to Pythagoras,

19^2 = 12^2 + x^2

x^2 = 19^2 - 12^2

x^2 = 361 - 144

x^2 = 217

x = $\sqrt{217}$

x = 14.73
