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.

The circumference of the hub cap of a tire is 83.96 centimeters. Find the area of this hub cap. Use 3.14 for . Use pencil and pa
Bess [88]

Answer:

Area = 561.2485 square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.

Step-by-step explanation:

As we know the circumference of a circle is 2\pi r

The radius of the hub cap needs to be devised to determine the area

83.96 = 2* 3.14*r

r = \frac{83.96}{2*3.14}

r = 13.37 centimeters

Area of the hub cap = \pi r^{2}

Substituting the devised value of r in the above equation, we get -

3.14 * 13.37^2\\

561.2485 square centimeter

If the circumference of the hub cap would have been smaller, then its radius would have been smaller and subsequently its area would also have been less.
