Finalmente, el angulo C se halla por medio de la misma ley:
X >- 5
-2x -4 < 3x +21
+4 +4
-2x < 3x +25
-3x -3x
-5x < +25
-5x/-5 25/-5
X > -5
Answer:
3 and 5
Step-by-step explanation:
factor tree is more appropriate.
Answer:
x = -2, y = -8
Step-by-step explanation:
13(y + 6) - 6y = 22
=> 13y + 78 - 6y = 22
=> 7y = -56
=> y = -8
x = -8 + 6
=> x = -2
Answer:
When k(x) is 2x² - 5x + 3, k(-3) = 36.
Step-by-step explanation:
k(x) = 2x² - 5x + 3
Substitute the input of x.
k(-3) = 2(-3)² - 5(-3) + 3
Square -3.
k(-3) = 2(9) - 5(-3) + 3
Multiply 2 and 9.
k(-3) = 18 - 5(-3) + 3
Multiply -5 and -3.
k(-3) = 18 + 15 + 3
Add 18 and 15.
k(-3) = 33 + 3
Add 33 and 3.
k(-3) = 36.
