Whatever decimals you choose, b HAS to be greater than a. It can't be the other way around where a is greater. So a possible answer could be, b=0.9 and a=0.3

You are making hair bows out of ribbon. You have 3/4 yard of ribbon and each bow takes 1/8 of a yard of ribbon. How many bows ca
Svetlanka [38]

Answer:

6 bows

Step-by-step explanation:

First find a common denominator. In this case, it would be eight. So now you would multiply your numerator by however much you multiplies your denominator.

3/4 would become 6/8.

6/8 divided by 1/8 is 6.

Factor out completely: 4a^2c^2-(a^2-b^2 c^2)^2
Alex17521 [72]

The expression 4a^2c^2 - (a^2-b^2+c^2)^2 has to be factored.

4a^2c^2 - (a^2 - b^2 + c^2)^2

=> (2ac)^2 - (a^2 - b^2 + c^2)^2

=> (2ac - a^2 + b^2 - c^2)(2ac + a^2 - b^2 + c^2)

=> (b^2 - (a^2 - 2ac + c^2))((a^2 + 2ac + c^2) - b^2)

=> (b^2 - (a - c)^2)((a + c)^2 - b^2)

=> (b - a + c)(b + a - c)(a + b + c)(a - b + c)
<span>
The factorized form of 4a^2c^2 - (a^2-b^2+c^2)^2 is (b - a + c)(b + a - c)(a + b + c)(a - b + c)</span>

A.(0,-3)<br> B.(3,0)<br> C.(0,3)<br> D.(-3,0) <br> Help please
Vinvika [58]

Answer:

Step-by-step explanation:

the solution to the system

= find the intersection of two lines

method( one )

solve the equations ( find(x , y) )

( 1 ) y = -x +3

( 2 ) y = x - 3

now , we let ( 1 ) + (2 )

we have 2y =0  ,thus y = 0

from ( 1 ) y = - x +3 , we know y = 0  ,

we rewrite ( 1 ) as 0 = -x + 3,thus x = 3

method( two)

see the intersection point of two lines

so the ans is B.(3 , 0)
