Answer:

f(- 2) = 2

Step-by-step explanation:

To evaluate f(- 2), substitute x = - 2 into f(x), that is

f(- 2) = 2(- 2) + 6 = - 4 + 6 = 2

What is the value of y? Y Y 60 O A. 120° B. 60° C. 40° O D. 30°

Grace [21]

Answer:

B. 60°

Step-by-step explanation:

1. The measure of all angles in a triangle sum up to 180°. This means that y + y + 60 = 120.

2. (Solving)

Step 1: Simplify both sides of the equation.

$(y+y)+(60)=180$
$2y + 60 = 180$

Step 2: Subtract 60 from both sides.

$2y + 60 - 60 = 180 - 60$
$2y = 120$

Step 3: Divide both sides by 2.

$\frac{2y}{2}=\frac{120}{2}$
$y = 60$

Step 4: Check if solution is correct.

$(60)+(60)+60 = 180$
$120 + 60 = 180$
$180 = 180$

Therefore, the answer is B. 60°.
