7 0

Answer:

2 ; 10

Step-by-step explanation:

a + B = 12

a - B = 8

a = 12 - B

(12 - B) - B = 8

a = 12 - B

12 - 2B = 8

B = 2

A = 10

Solve each inequality below. Represent the solutions on number lines. 7x − 2 < 3 + 2x
LekaFEV [45]
Hi, I would be glad to help you here. 

<span>7x − 2 < 3 + 2x 

Move terms 

7x - 2x - 2 < 3 

Collect the like terms

(7x - 2x) = 5x (<3 + 2 stays the same) 

Calculate 

5x (<3 + 2 = 5) 

5x <5 

Divide both sides of the inequality by (5) giving you, 

x < 1 

So, finally in a total the correct answer here is (x < 1)

What are the zeros of the function? what are their multiplicities?<br> f(x)=x^4-4x^3+3x^2
-Dominant- [34]
Since each term contains x, x= 0 is one answer Also as x^2 is a factor  it has duplicity 2.
Factoring:-

x^2 (x^2 - 4x + 3) = 0
x^2( x - 3)(x - 1) = 0

so x = 3 and x = 1 are also zeros


Answer:-   x = 0 (duplicity 2), x = 1 and x = 3.
