When you graph a system of two linear equations, which outcome is NOT possible?

Mathematics

Bumek [7]3 years ago

A. The lines do not intersect, so there are no solutions.

This is true, if the line's never intersect and don't have a common/same point, there are no solutions.

B. The lines intersect at one point, so the system has one solution.

This is true because they have 1 same point so they have 1 solution

C. The lines intersect in two different points, so the system has two solutions.

This is not possible, straight lines can only intersect 1 time. If the lines are curved, then they can intersect more than once

D. The graphs of the two equations are the same line, so there are infinitely many solutions.

This is true because they will <u>always</u> have the same points, so they will have an infinite number of solutions

calculate the scale factor of abc to def enter answer as a whole number or as a fraction into lowest terms
SVETLANKA909090 [29]

Answer:

Scale is 1/6

Step-by-step explanation:

Since all sides and angles are identical these are congruent triangles

3 ways to solve:

Scale Factor = DE / AB = 12/72 = 1/6

Scale Factor = DF/AC = 7/42 = 1/6

Scale Factor = EF/CB = 11/66 = 1/6

HELP PLEASE I HAVE A COUPLE MORE! Please help and fast would be great! BRAINLEST!!!
Harlamova29_29 [7]

Answer:

b. slope: -5; y-intercept: 7

Step-by-step explanation:

We are given the equation:

y + 5x = 7

To find the slope and y-intercept of the line, it would be helpful to get the equation into slope-intercept form. The slope-intercept form of a line is:

y = mx + b

where m is the slope and b is the y-intercept.

Lets get the given equation into slope-intercept form.

y + 5x = 7

Subtract 5x from both sides.

y = -5x + 7

Now we have the equation in slope-intercept form. By looking at the equation, we can see that the slope is -5 and that the y-intercept is 7.

The correct answer choice would be b.

I hope you find my answer and explanation to be helpful. Happy studying.
