Answer:
Arav is 30 and Pawan is 40
Step-by-step explanation:
We can call Arav's age x and Pawan's age x + 10, therefore we can write the following equation:
1/7((x + 10) - 5) = 1/5(x - 5)
1/7(x + 5) = 1/5(x - 5)
5(x + 5) = 7(x - 5)
5x + 25 = 7x - 35
-2x = -60
x = 30 so x + 10 = 40
Answer:
The 2nd one
Step-by-step explanation:
2 1/3 are greater then 2 1/6
Answer:
-11
Step-by-step explanation:
The answer to the first one sould be -11
2x^3 +5x^2−x−6
Write 5x^2 as 4x^2 + x^2......and we have.....
2x^3 + 4x^2 + x^2 - x - 6
2x^2 ( x + 2) + ( x + 2)(x - 3)
(x + 2) [ 2x^2 + x - 3]
(x + 2) (2x +3) (x - 1)
x^3−4x^2−3x+18 = 0
Using some synthetic division, we have
3 [ 1 - 4 -3 18 ]
3 -3 -18
_______________
1 -1 -6 0
The remaining polynomial is x^2 - x - 6 which factors as (x - 3) ( x + 2)
So .... the factored form is (x - 3) ( x - 3) ( x + 2) = ( x + 2) ( x - 3)^2 = 0
D. Raisin is your answer!!!
Answer:
y=-3/13x-89/13
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=(-8)-(-5)/5-(-8)
m=-3/13
y-y=m(x-x1)
y-(-8)=-3/13(x-5)
y+8= -3/13x+15/13
-8 -8
y=-3/13x-89/13
