Step-by-step explanation:
<u>Step 1: Define Equation</u>
2/3x = 27
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 2/3 on both sides: x = 81/2
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 2/3(81/2) = 27
- Multiply: 27 = 27
Here we see that 27 does indeed equal 27.
∴ x = 81/2 is the solution to the equation.
The length of ST = 20.
S is located at 5, so t would need to be 20 units more than s.
t = 5 + 20 = 25
t is located at 25.
1. Factor P (x) = x^4 - 4x^3 + 3x^2:
1a. Factor out the GCF or x^2:
P (x) = x^2 (x^2- 4x + 3)
1b. Factor the trinomial. What multiplies to make 3 and adds to make -4?
(-1)+(-3) = -4 and (-1)(-3) = 3
P (x) = x^2 (x-1) (x-3)
2. Find the zeros be setting each factor equal to 0:
x^2 = 0 if x=0, with multiplicity 2
x-1 = 0 if x=1
x-3 = 0 if x=3
Your zeros are 0, 0, 1, and 3.
