Answer:
second option
Step-by-step explanation:
Given
f(x) = - 
+ 9
- 18x³
To find the zeros let f(x) = 0, that is
- + 9 - 18x³ = 0 ( multiply through by - 1 )
- 9 + 18x³ = 0 ← factor out x³ from each term
x³ (x² - 9x + 18) = 0 ← in standard form
x³(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x³ = 0 ⇒ x = 0 with multiplicity 3
x - 3 = 0 ⇒ x = 3 with multiplicity 1
x - 6 = 0 ⇒ x = 6 with multiplicity 1
She needs to buy two 1 gallon cans
high 9 ft=1side=9ft
2 sides=18ft
140-18=122 122/2=61 the other side is 61ft
Area 61x9=549 squared ft
549/300=1.83 cans
She will need to buy two 1 gallon cans
Step 1: simplify the equation by using the distributive property where applicable and combining like trems
Step 2: Collect all the variables on one side by either adding or subtracting.
step 3:Using inverse operations for addition and subtraction can removecontants ,toget the vaiables and constants on opposite sides.
Step 4:Inverse operations, such as multiplying and dividing can be used to eliminate coefficients in front of variables to get the variables by themselves
Answer:
2x-3y=20
12x+8y=-192
Solution
In the determinant of the matrix to find the variable "x" [Ax], we replace the coefficients of "x" (2 and 12) by the independent terms (20 and -192 respectively).
In the determinant of the matrix to find the variable "y" [Ay], we replace the coefficients of "y" (-3 and 8) by the independent terms (20 and -192 respectively).
Answer:
-4 + 4
Step-by-step explanation:
because when you add a negative number with a positive number the sum will always equal 0
