Answer:

(d) y = -5/2x -3

Step-by-step explanation:

All of the offered choices are in slope-intercept form, so it makes sense to put the given equation in that form. Solving for y, we get ...

5x +2y = -4

2y = -5x -4 . . . . . subtract 5x

y = -5/2x -2 . . . . . divide by 2

The system of equations will have no solution if the equations are "inconsistent." That will be the case when the slope is the same, but the y-intercepts are different. That means you're looking for an answer of the form ...

y = -5/2x +c . . . . . . where c is not -2

This matches the last choice:

y = -5/2x -3

2x≤4

I'm not sure how else to help you in this situation, without you providing me with more information. If you want the solution for x, you would just divide both sides by the coefficient of the variable, or 2, resulting in the inequality:

x ≤ 2

Hope this helps! Comment if you need to add info or have any more questions about this problem.

Descibe the mothod of solving problems with numbers in standard form ?? I have 5 MIN

BlackZzzverrR [31]

Answer: A standard equation is set up like this: Ax + By = C (where A, B, and C represent numbers). To find the slope (or the rate at which something changes) you must divide the value of A by the value of B (A / B).

Answer:

50.4 km (Answer B)

Step-by-step explanation:

From this information, we are able to create a proportion, 2cm/21km= 4.8cm/x km (x representing the actual distance). After cross-multiplying and simplifying, you get an answer of 50.4km. Hope this helps!
