Answer:
y = (x+5)(x+2)(4x-3)
Step-by-step explanation:
This is almost correct but the problem is that the signs should be flipped...
Why? If we solve for x-5=0 the answer we would get is 5, but the graph shows -5 as its zero so that doesn't match
The revised version would be the opposite signs
y = (x+5)(x+2)(4x-3)
Answer:
C = $5p + $3 where C is the final cost, and p is the number of pounds of blueberries you pick
Step-by-step explanation:
They charge a flat rate of $3 just for the bucket, and 5 per pound.
5p represents how much you'll pay based on how many pounds you pick, each pound costs $5,
C = $5p + $3 means the Cost is $5 per pound (p) plus $3 for the bucket
The number of hours since the bakery opened, plus the number of remaining boxes is equal to 42.
x + y = 42
So the number of boxes remaining is equal to y, and
y = 42 - x, the number of hours the bakery was open.
So at the start of the day, the bakery was open for 0 hours, and y, the number of boxes "remaining" at the start of the day, will be equal to 42 - 0 = 42.
Answer:
{-15, -5}
Step-by-step explanation:
The constant on the left needs to be the square of half the x-coefficient:
(20/2)^2 = 100
To get it to that value, we can add 18 to both sides of the equation:
x^2 +20x +100 = 25 . . . add 18 to both sides of the equation
(x +10)^2 = 25 . . . . . . . . write the left side as a square
x +10 = ±√25 = ±5 . . . . . take the square root
x = -10 ±5 = {-15, -5}
The solutions are x = -15 and x = -5.

The attached graph shows the solutions to ...
x^2 +20x +82 -7 = 0 . . . . . the result of subtracting 7 from both sides
