Answer: x = -3
Step-by-step explanation:Step by step solution :
Step 1 :
Pulling out like terms :
1.1 Pull out like factors :
-x - 3 = -1 • (x + 3)
Equation at the end of step 1 :
Step 2 :
Solving a Single Variable Equation :
2.1 Solve : -x-3 = 0
Add 3 to both sides of the equation :
-x = 3
Multiply both sides of the equation by (-1) : x = -3
One solution was found :
x = -3
Given parameters:
y varies directly as w;
This interpreted implies that as y increases, we increases by a certain factor or amount;
So, y ∝ w
y = kw
where k is the constant of proportionality
Now, given that y = 8 and w = 2
Input in the equation to solve for k;
8 = k x 2
Solving k gives, k = 4
Now to the second part,
if v is directly proportional to w;
v = k w
So v = 4w
The equation that relates v to w is v = 4w
Evaluate the trigonometric expression using sum and difference formulas.
So if they lost 2 yards on the first play and on the following three plays they lost 2 yards they lost 4 yards total because it doesnt say they lost 2 yards on each of the three play so they would only lose 4 yards
