The answer is 5. After adding all the numbers I divided it by how much number there is so 3+3+4+4+5+5+5+5+6+7+8 which = 55 and then divide by 11 cus that’s how much numbers there’s are which makes the answer 5

A system of equations is given below. y=1/2x-3 and -1/2x-3. Which of the following statements best describes the two lines?

pantera1 [17]

"They have different slopes but the same y-intercept, so they have one solution" is the statement which best describes the two lines.

Answer: Option D

<u>Step-by-step explanation:</u>

Given equations:

$y=\left(\frac{1}{2} \times x\right)-3$

$y=\left(-\frac{1}{2} \times x\right)-3$

As we know that the slope intercept form of a line is

y = m x + c

So, from equation 1 and equation 2 we can see that

$m_{1}=\frac{1}{2} \quad \text { and } c_{1}=-3$

$m_{2}=-\frac{1}{2} \text { and } c_{2}=-3$

So, from the above expressions, we can say that both lines have different slopes but have same y – intercept with one common solution when x = 0.

How do I solve this equation ???

Anastaziya [24]

To solve for the variable $b$ , we have to make it alone. The first thing we do is add $6.5$ to both sides of the equation:

$13.7b-6.5+6.5=-2.3b+8.3+6.5\\13.7b=-2.3b+14.8$

Now add $2.3$ to both sides:

$13.7b+2.3b=-2.3b+14.8+2.3b\\16b=14.8$

Finally, divide both sides by 16 to get the final answer:

$\frac{16b}{16} =\frac{14.8}{16}$

Therefore,

$b=0.3$

Hope this helps!
