Explanation:
Angles 1 and 3 are vertical angles, which are always congruent.
Vertical angles form when we have an X shape like this. They are opposite one another. Angles 2 and 4 form the other pair of congruent vertical angles.
Answer:
f(-2) means that x = -2
f(-2) = 65
Step-by-step explanation:
f(x) = 6(8 - x) + 5
f(-2) = 6(8 + 2) + 5
f(-2) = 6(10) +5
f(-2) = 60 + 5
f(-2) = 65
It is -1, you first make the -1 positive but then the negative sign outside makes that 1 turn -1
I think the mean with outliers excluded are called trimmean.
Answer: x = 7 or x = -8
x² + x - 56 = 0
⇔ x² + 8x - 7x - 56 = 0
⇔ x(x + 8) - 7(x + 8) = 0
⇔ (x - 7)(x + 8) = 0
⇔ x - 7 = 0
or x + 8 = 0
⇔ x = 7 or x = -8
