I need help combining like terms 2-x^3-4+3y+y+y+5
OLEGan [10]

Answer:

-x³ + 5y + 3

Step-by-step explanation:

It helps to rewrite the given polynomial according to its degree (exponent), in <u>descending</u> order. Also, for variables without a coefficient, it helps to include "1" with it to make it less confusing when combining like terms.

- x³ + 3y + ( 1 )y + ( 1 )y + 5 + 2 - 4

One way to simplify a polynomial is to combine the like terms if there are any. Two or more terms in a polynomial are like terms if they have the same variable(s) with the same exponent.

- x³ is the only term with an exponent of 3, so we wouldn't have to combine it with other terms. We need to combine the terms with the variable "y," as they have the same degree of 1.

- x³ + 5y + 5 + 2 - 4

Lastly, combine the constants (5 + 2 - 4):

- x³ + 5y + 3

Which of the following points is a solution to the system of equations shown?
puteri [66]
Using Substitute method:

Replace y value of equation 2 into equation 1:
4x + (x+6) = 1

Solve for x:
4x + x + 6 = 1
5x = 1 - 6
5x = -5
x = -5/5
x = -1

Pick any of the two equation, replace x with it's value -1 and solve for y:
y = (-1) + 6
y = -1 + 6
y = 5

Solution: (-1, 5)

The equation that represents this description is h = 20c + 60 because hours (h) is our dependent variable and cost (c) is our in
MrRissso [65]

Answer:

c= 20h + 60

Step-by-step explanation:

The correct dependent variable for this equation is "c" cost of Mr Z's tutoring. The independent variable is "h" hours of tutoring. This is because the independent variable h hours should determine the cost of tutoring c. Therefore the equation can be interpreted: if there are h hours of tutoring which cost 20 per hour, total cost is equal c. Also slope of the equation is 20, coefficient of h.
