If x=-5 is a zero, then the first factor of the polynomial would be (x + 5 )
To find the other two factors we can divide the polynomial by the expression (x+5).
Using synthetic division, we have:
-5 I 4 15 -24 5 (Coefficients of the dividend)
I -20 25 -5 (Multiplying each coefficient by the results of the substraction and adding)
-----------------------------------------------------------------------------------
4 -5 1 0 (Coefficients of the quotient)
The result of the division is 4x^2 - 5x + 1. Factoring it, we have:
4x^2 - 4x -x + 1 (Separating -5x into -x and -4x)
4x (x - 1) - (x -1) (Factoring each pair of terms)
(x-1)(4x-1) (Factoring using the common factor)
So the answer would be:
(x + 5 )(x-1)(4x-1)

ANSWER: (12,11), (x,y)
12 steps to the right on the x-axismaking the value a plus, and 11 steps up on the y axis making the numeral positive as well.
Answer:
x = 45
y = 15
Step-by-step explanation:
Given that:
x = pineapple smoothies
y = mango smoothies
According to given conditions:
x + y = 60.................... eq1
$2.75 x + $3.25y = $172.50 ............ eq2
By taking eq1
x + y = 60
x = 60 - y
Putting value of x in eq2
$2.75 (60 - y) + $3.25y = $172.50
By simplifying
$165 - $2.75y + $3.25y = $172.50
Adding like terms:
$0.5y = $172.50 - $165
$0.5y = $7.5
Dividing both sides by $0.5
y =7.5/0.5
y =15
Putting value of y in eq 1
x + 15 = 60
x = 60 -15
x = 45
So there are 45 pineapple smoothies and 15 mango smoothies.
i hope it will help you!
