Answer:
w= 7/4 +1/4 √89 OR w= 7/4 -1/4 √89
Step-by-step explanation:
2w^2-8w-1= (w-2)^2
Multiply (w-2)^2 by (-1)
2w^2-8w-1= -w+2^2
Add w to both sides
2w^2-7w-1= 4
Add 1 to both sides therefore that -1 cancels
2w^2-7w=5
Get the equation equal to 0 by subtracting 5 from both sides
2w^2-7w-5=0
Use the quadratic formula to solve
x= -(-7) plus or minus √(-7)-4(2)(-5)/2(2)
7 plus or minus √89/4
Answer: y = -3x - 2
Step-by-step explanation:
y = -3x - 2
yint = -2
slope = -3/1

Step-by-step explanation:
Answer:
At first instance, they can eat 3 SMALL pizzas together, while the total number of pizzas they can eat if there are subsequent instances is
3 × (Number of instance)
Step-by-step explanation:
Here, we have a word math problem, with Joey and his 2 friends who can eat the same amount as him
That is if the amount Joey can eat is x then each of his two friends can eat x hence total amount Joey and the two friends can eat is
x + 2x = 3x,
Where x is an number eaten per person at an instant
Therefore, if they decide to order all SMALL pizzas, the number of pizzas they can eat at the first instant is 3 × 1 = 3 SMALL pizzas
at subsequent instance, the number of pizzas eaten in total is 3·x pizzas.
