How many solutions does the system 2y=10x-14 and 5x-y=7 have

Answers

Answer 1

Answer:

Answer: 1 solution at (2.8, 7)

Answer 2

Answer:

Answer:

All real numbers

Step-by-step explanation:

Take 2y=10x-14 and divide both sides by 2. Once you do that, you get y=5x-7. Use substitution and plug that into 5x-y=7. You get 5x-(5x-7)=7 which eventually simplifies to 7=7 which shows that you can plug in an infinite number of solutions so the answer is all real numbers.

Answers

Answer:

Not telling you the answer that just the steps, that would be cheating.

Step-by-step explanation:

1. Mulitply 1000 by the fraction.

2. Simplify it(the numbers 1000 and 2 to 500 and 1)

3. Then divide the exponents(you know this I taught you:)

4. You then will get your answer! (hint: it has a negative exponent :)

5. Please try not to use Brainly next time, try it yourself:) or I may take points off, ask me next time.

When x ≠ 0, the expression x²/2x⁵ × 1000 simplifies to 500/x³. This is obtained by simplifying the fraction and then multiplying by 1000.

To simplify the expression (x²/2x⁵) × 1000, we can start by simplifying the fraction within the parentheses.

First, let's deal with the fraction x²/2x⁵. We can simplify it by using the rule of exponents, which states that x^m/x^n = x^(m-n) when dividing with the same base. In this case, we have x²/2x⁵, so:

x²/2x⁵ = (x²)/(2x⁵) = (x²/x⁵) * (1/2) = x^(2-5) * (1/2) = x^(-3) * (1/2).

Now, we have the fraction x^(-3) * (1/2). To simplify this further, we can rewrite x^(-3) as 1/x^3. Therefore, the expression becomes:

(1/x^3) * (1/2) = 1/(2x³).

Now that we've simplified the fraction within the parentheses, we can multiply it by 1000:

(1/(2x³)) * 1000 = 1000/(2x³) = 500/x³.

So, the expression x²/2x⁵ × 1000 simplifies to 500/x³ when x ≠ 0.

What is the next logical statement in the proof below?given: M is the midpoint of AB
prove:2(AM) = AB
a) AM+AM=AB
b) AM=AB-MB
c) AB=AM+MB
d) M (A+B)=AB

Answers

First, we have write down, in the language of mathematics that M is the midpoint of AB. This means that AB will have two parts, each of them ending with (or beginning with) M. This is how we do it:

c) AB=AM+MB

The correct answer is AM+AM=AB I know what test this is.
