A gardener has 8 pounds of fertilizer. He packs the fertilizer into 5/8 pound bags. What is the maximum number of 5/8 pound bags he can pack?
so first you multiply 8 pounds times 5 from 5/8 which is 40/8 pounds bags
now how many 8s can fit in 40
40 divided by 8 =5
so he can pack 5 maximum bags
(1)
we are given

we can use quadratic formula


now, we can compare and find a , b and c
we get

now, we can plug these values into quadratic formula


we can simplify it



so, we will get solution
{−3+i, −3−i}.........Answer
(2)
we are given equation as

Since, Jamal solve this equation by completing square
so, firstly we will move constant term on right side
so, subtract both sides by 14


we can write

so, we will add both sides by 4^2

we get

Answer:
If Abraham divides them into 2 separate groups, he should have 17 marbles on each group.
Step-by-step explanation:
Part A:
Express the given number of hours and velocities of the cyclist as ordered pairs. The time (number of hours) can be our abscissa (x-coordinate) and the velocities can be our ordinate (y-coordinate). The coordinates are therefore (2, 18) and (4, 4). The equation that can be formed in this is established through the two-point equation.
(y - y₁) = ((y₂ - y₁)/(x₂ - x₁))(x - x₁)
Substitute the known variables.
(y - 18) = ((4 - 18)/(4 - 2))(x - 2)
Simplifying the equation,
y - 18 = -7(x - 2)
y = -7x + 32
<em>ANSWER: y = -7x + 32
</em>Part B: This can be graph in the Cartesian plane and numbers 1 to 8 can be substituted to y and take note of the ordered pairs for each point. The slope of the line should be -7 and the y-intercept is 32.<em>

Try a few:
1+3+5=9 too small
5+7+9= 21 just right
The greatest integer is 9
