The 3 inside angles of a triangle need to equal 180 degrees.
You are given 2 of the angles that are 60 degrees each
The total of the 2 angles you know is 60 + 60 = 120 degrees
So y = 180 - 120 = 60 degrees
Answer:
The system of equations is
y = 0.25(x - 10)² + 6
y = -0.7941x - 0.2938
Answer:
Los coeficientes (coefficients)
Step-by-step explanation:
Un número multiplicado por una variable es un coeficiente. 3 y 15 se multiplican por x, por lo que esos números son coeficientes.
(A number multiplied by a variable is a coefficient. 3 and 15 are both being multiplied by x so those numbers are coefficients.)

1. Expand
- 3 - 4m = 28m - 28 - 7m
2. Simplify 28m - 28 - 7m to 21m - 28
- 3 - 4m = 21m - 28
3. Add 4m to both sides
- 3 = 21m - 28 + 4m
4. Simplify 21m - 28 + 4m to 25m - 28
-3 = 25m - 28
5. Add 28 to both sides
- 3 + 28 = 25m
6. Simplify - 3 + 28 to 25
25 = 25m
7. Divide both sides by 25
1 = m
8. Switch sides
m = 1
