What is the solution to the system of linear equations below? 2/5x−y=6 −2x+5y=−30 Select one: A. (-13, 14) B. (-5, -8) C. no solution D. infinitely many solutions

Answers

Answer:

D. Infinitely many solutions

Step-by-step explanation:

[tex]-\frac{2}{5}x-y=6 | -2x+5y=-30[/tex]

1.Since neither equation contains an isolated. However, we can isolate -y in the first equation by adding [tex]\frac{2}{5}x[/tex] to both sides.

Like this: [tex]\frac{2}{5}x-\frac{2}{5}x-y=6-\frac{2}{5}x[/tex]

ending up with [tex]y=6-\frac{2}{5}x[/tex]

2.Now, we can change y to a positive y. By doing so, we divide -y by the entire equation.

Like this [tex]\frac{-y=6-\frac{2}{5}x }{-y}[/tex]

Ending with [tex]y=-6+\frac{2}{5}x[/tex]

3.Now, we can plug the expression [tex]-6+\frac{2}{5}x[/tex] into the second equation as a substitute for y, and solve for x. Then, we can use x to calculate y.

Like this [tex]-2x+5(-6+\frac{2}{5}x)=-30\\ -2x-30+2x=-30\\[/tex]

4. Since -2x+2x would cancel out and leave -30=-30. This is true because we know -30 equals -30 with no variable in sight.

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y= -100 x= 100

Step-by-step explanation:    The form y=mx+b means slope m and y-intercept b; similarly, the form y=mx+a means slope m and y-intercept a. The form y=m(x-a) is essentially different from the other two forms, and means slope m and x-intercept (instead of y-intercept) a.

Okay so i’m thing that the number that is gray means that, that is the measure of the whole angle. If I am correct then that means all you have to do is subtract the angle given from the whole angle to get x. Here is what I mean.

1. (117° - 94° = 23°) so x = 23°


2. These are vertical angles, which means that they will equal each other. So x = 148°.


3. (174° - 68° = 106°) so, x = 106°


4. (50° - 32° = 18°) so, x = 18°


5. Okay so since this is a straight line, it the bottom half does not matter. The straight line equals 180°. So here is you equation.
(125° + x° + 30° = 180°. So let us add 125 & 30, which would get us 155°. Now let us subtract 155° from 180°, and that would get us, 25°. So x = 25°.


6. Once again these are vertical angles, meaning the will equal each other. So x = 113°.


7. So since x and 30° are on a straight line, x, 30° and the middle angle should equal 180°: Since the middle angle is vertical to 105°, the middle angle equals 105°. So now your equation is. 30° + 105° + x° = 180°. Now let us add 30° and 105° which would give us 135°. Now let us subtract 135° from 180° and that would give us, 45°, so therefore, x = 45°.



8. All you have to do is add all three angles. So your equation is:
(30° + 15° + 89°)
This will give you 134°. Therefore, x = 134°.


9. Once again these are vertical angles so x = 162°.


10. Okay so here your equation will be x = 90° + 29°. Imma tell you why.

Now the angle with the box in it, is obviously 90°. x is vertical from the whole angle on 90° and 29°, which means what? THEY SHOULD EQUAL EACH OTHER. So 90° + 29° = 119°. So
x = 119°.
