Substitution method...need help.. started but cant finish
trapecia [35]

Solve either equation for either variable. Since the second one has y on its own, the easiest choice is to solve that for y.

-5x + y = 13   ⇒   y = 5x + 13

Now substitute this into the other equation to eliminate y and rewrite it entirely in terms of x :

-3x + 3y = 3   ⇒   -3x + 3 (5x + 13) = 3

Simplify and solve for x :

-3x + 15x + 39 = 3

12x = -36

x = -3

Substitute this into either original equation to solve for y. Plugging x = -3 into the first equation would give

-3 (-3) + 3y = 3

9 + 3y = 3

3y = -6

y = -2

So the solution to the system of equations is (x, y) = (-3, -2).

Which of the following values are solutions to the inequality -10_>6x-4
qaws [65]

Answer:

3rd option

Step-by-step explanation:

- 10 ≥ 6x - 4 ( add 4 to both sides )

- 6 ≥ 6x , then

6x ≤ - 6 ( divide both sides by 6 )

x ≤ - 1

Thus x = - 1 is a solution to the inequality

How to determine the missing angle
Elena L [17]
To determine the missing angle you simply subtract the angle you know from 180 because a flat line is 180 degrees. If it is a circle you subtract the number from 360. Hope this helps!
