can someone at least help me with this math problem that i'm getting frustrated with. 2y^3-4x^2-4-1+3x^2-3y^3-y^3

ans= -2y^3-x^2-5

Step-by-step explanation:

(i) write the question nicely again.

(ii) collect the like and unlike terms.

(iii)solve (add and minus ) according to their like and unlike terms.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
