4 0

Answer: y = -4x + 3

Step-by-step explanation:

y = mx + b

=> y = -4x + b

Find "B":

y = -4x + b

=> 3 = -4(0) + b

=> b = 3

so y = -4x + 3

-2(3x-2) + 2x = -6X - 10
julsineya [31]

Answer:

x =  - 3

Step-by-step explanation:

- 2(3x - 2) + 2x =  - 6x - 10

=  >  - 6x - 4 + 2x =  - 6x - 10

=  >  - 4x - 4 =  - 6x - 10

=  >  - (4x + 4) =  - (6x + 10)

=  > 4x + 4 = 6x + 10

Keeping all like terms in L.H.S ,

=  > 6x - 4x = 4 - 10

=  > 2x =  - 6

=  > x =  \frac{ - 6}{2}  =  - 3

Consider the Polynomial P(x)=x^3-5x^2-x+5. is (x-5) a factor?
Alborosie

Answer:

Option B, Yes, the remainder is 0, so x-5 is a factor of P(x)

Step-by-step explanation:

<u>Step 1:  Factor</u>

p(x) = x^3 - 5x^2 - x + 5

<em>p(x) = (x - 5)(x + 1)(x - 1)</em>

<em />

<em>Yes, the remainder is 0 so, x-5 is a factor of p(x)</em>

<em />

Answer:  Option B, Yes, the remainder is 0, so x-5 is a factor of P(x)

8.5x+51.86=-11.5x+51.76
solniwko [45]
Add, -11.5x and move it over to 8.5x

Then, subtract them together and you get 20x + 51.86 = 51.76

And you move (subtract) 51. 86 over to 51.76, subtract that and you get             20x = -0.1

Divide, and your answer is -200
