Abed says he has written a system of two linear equations that has an infinite number of solutions. One of the equations of the system is y = 3x – 1. Which could be the other equation?

Answers

Answer 1

Answer: y = 3x + 23x – y = 23x – y = 1 3x + y = 1

Answer 2

Answer:

The correct answer is:

Any equation that is a multiple of y=3x-1.

Explanation:

In order to graph as the same line, the equations must be the same. This means that all pieces of the first equation must be multiplied by the same factor, or the equation must be rewritten.

In which quadrant is the number –14 – 5i located on the complex plane? I II III IV

Answers

Answer:

III

Step-by-step explanation:

go 14 left and 5 down, and you're in the third quadrant

Answer:

III (Third quadrant)

Step-by-step explanation:

Okay, in terms of complex numbers, the x axis is the imaginary scale while the y axis is the real scale. And this works just like a normal x and y axis! We can break down -14-5i into -5i and -14, and -5i is the imaginary number on the x axis, so we move five units to the left from the origin. -14 is the real number, so we then move down 14 units, and we end up with a coordinate that is in the III, or third, quadrant. Hope this helps! :)

Which characteristic of a data set makes a linear regression model unreasonable? a slope close to 0 a correlation coefficient close to 0 a slope close to –1 a correlation coefficient close to –1

Answers

Answer:

A correlation coefficient close to zero

Step-by-step explanation:

This makes linear regression unreasonable because the correlation coefficient shows how related the data points are, -1 and 1 being very strong and 0 being uncorrelated. So the line of best fit would not make sense because the data points are random in relation to one another.

Answer: B. A correlation coefficient close to zero

Step-by-step explanation:

Write an equation for the linr that is parallel to the given lin and passes through the given point. y=5x+10; (2,14)y=1/5x+4
y=-1/5x-4
y=5x=68
y=5x+4

Answers

y = 5x + 10...slope here is 5. A parallel line will have the same slope.

y = mx + b
slope(m) = 5
(2,14)...x = 2 and y = 14
now we sub and find b, the y int
14 = 5(2) + b
14 = 10 + b
14 - 10 = b
4 = b

so ur parallel equation is : y = 5x + 4
