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.

Two numbers total 86 and have a difference of 12. Find the two numbers.

mestny [16]

Let the two numbers be x and y.

x + y = 86
+
x - y = 12
_________
2x + 0 = 98
__________

2x = 98

x = 98/2

x = 49

From x + y = 86

49 + y = 86

y = 86 - 49

y = 37

The numbers are 49 and 37.

Find x =

olga nikolaevna [1]

If they proportional, it implies

(x+2)/(x-1) = 8/10

Or 10x +20 = 8x-8

Or 2x = -28 or x = -14
