(x+5) (x+3)
x^2 = (x+?) (x+?)
8x+15= 5&3
8x= 5•3
15= 5+3
Answer:
Step-by-step explanation:
Because the function is a product, the zeros will occur when any term is equal to zero. For
(x-1)(x+3)(2x+1) the value will be zero when x=1,-3, or -1/2 so the points are
(-3,0), (-1/2,0), and (1,0)
Answer:
a) Let's define the variables:
t = number of tulips bought
r = number of roses bought
We know that each tulip costs $5, and each rose costs $3.
Then the total cost will be:
$5*t + $3*r
We know that Morty spent a total of $54, then we have the equation:
$5*t + $3*r = $54
We also know that he bought a total of 14 flowers, then:
r + t = 14
Then the system of equations is:
$5*t + $3*r = $54
r + t = 14
b) To solve the system, first, we need to isolate one of the variables in one of the equations. I will isolate r in the second one:
r = 14 - t
Now we can replace this into the other equation:
$5*t + $3*r = $54
$5*t + $3*(14 - t) = $54
Now we can solve this for t.
$5*t + $3*14 - $3*t = $54
$2*t + $42 = $54
$2*t = $54 - $42 = $12
t = $12/$2 = 6
t = 6
He bought 6 tulips.
Now we can use the equation r = 14 - t
r = 14 - 6 = 8
r = 8
He bought 8 roses.

Original investment = 5,175
Gain = 5,302.305
Subtract them both and get = <span>127.305</span>
