"Explain why the solution of a system of linear equations is the point of intersection of their graphs"
Can you please explain this to be in a simpler form?

Answers

Answer 1

Answer:

Step-by-step explanation:

The solution of a system of linear equations is the point of intersection of their graphs because the intersection represents the only x or y values that will satisfy both/all equations. The graph visually shows that the intersection of these equations is the only spot on the graph that all of the equations have in common. This means that only this spot will satisfy all equations. For example, the intersection may be (0,1); this means that for all equations an x value of 0 will always result in the y value of 1. However, an x or y value that satisfies one equation may not satisfy the others if they do not lead to the desired outcome.

if i’m not mistaken it should be 55 because if you find the area of the whole triangle and subtract the mini rectangle you should get the shape
i’m pretty sure the answer is 15. this is because i split the triangle into 2 parts, then i multiplied 5x4 for the first triangle which equals 20, but then u have to divide it by 2 bc the formula for a triangle is A=1/2 (b x h) so then the answer for the first triangle is 10. now you have to do it to the other little triangle which gives u 5. at this point you have to add 10+5 which gives you 15. therefore the answer for this question is 15. i hope this helps!

Answers

Answer:

l = 14

Step-by-step explanation:

The perimeter of a rectangle is

P =2(l+w)

The width is x-6

w = x-6

The length is 8 units longer than the width

l = w+8

l = x-6+8

l = x+2

We can substitute this into the equation for Perimeter, which is given as 40

40 = 2(x+2 + x-6)

Combine like terms

40 =2 (2x-4)

Divide by 2

40/2 = 2/2 (2x-4)

20 = 2x-4

Add 4 to each side

20+4 =2x-4+4

24 = 2x

Divide by 2

24/2 =2x/2

12=x

We want to know the length

l = x+2

l =12+2

l = 14

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Multiply the length that you have been given by 2

2: Then, subtract the result from the perimeter.

3: You now have the total length for the remaining 2 sides.

4: Width or height is the number divided by 2.

28m⁷n⁵

Step-by-step explanation:

You would first multiply 14 by 2. You would then multiply (which is really addition when it comes to exponents) your like-term exponents.

(14m²n⁵)(2m⁵) =28m⁷n⁵

14(2) = 28

m² + m⁵=m⁷

n⁵ + 0 = n⁵

Answer:

[tex]28 {m}^{7} {n}^{5} [/tex]

Step-by-step explanation:

14*2=28; m^2*m^5=m^7.

When you're working with multiplication of powers, you have to add the exponents. For example

[tex] {x}^{4} \times {x}^{2} = {x}^{6} [/tex]

Because

[tex] {x}^{4} = x \times x \times x \times x \\ {x}^{2} = x \times x \\ {x}^{4} \times {x}^{2} = x \times x \times x \times x \times x \times x = {x}^{6} [/tex]

You and your friends went to UNO's for dinner (way back in 2019). Together the total bill for your meals was $40. You have a 15%-off coupon for the meal! Then, after the discount, a 7% sales tax is applied. What is the final price, after the discount and the tax, that you are your friends have to pay for the meal?

Answers

Answer:

$36.38

Step by step explanation:

First, we need to find out what 1% of $40 dollars is. To do this, we divide 40 by 100.

This gives us $0.40.

To then find out fifteen percent of $40, you then times $0.40 by 15.

This gives us 6 dollars.

Now, to work out the discount, we take 6 from 40.

$40 - $6 = $34

Now we have to work out the tax.

Again, we have to work out what 1% of $34 is.

This gives us $0.34

Then times that by 7 to find 7%

0.34 x 7 = $2.38

Since this is tax we have to add instead of subtracting.

$34 + $2.38 = $36.38 as the final bill.

The answer to your question is $36.38
