What value of X makes the equation true -7x - (-5-x) = -9(2x-1) -1
Bond [772]

Answer:

x = 1/4

Step-by-step explanation:

-7x - (-5-x) = -9(2x-1) -1

-7x + 5 + x = -18x + 9 - 1

combine like terms:

-6x + 5 = -18x + 8

add 18x to each side of the equation:

12x + 5 = 8

subtract 5 from each side:

12x = 3

divide both sides by 12:

x = 3/12 = 1/4

The point (x, y) is proportional to the point (2, 5). Select all the true statements.
Mnenie [13.5K]

Step-by-step explanation:

(x, y) is a solution to y = 5/2X

(x, y) is a solution to y=x+3.

The ratio of Y/X is equivalent to 5/2

Point (x, y) is the same point as (5, 2).

A straight line through points (2, 5) and (x, y) will pass through the origin.

What is the degree of this polynomial -2a^3b^2+5ab^5+7b^4+8
Vlad1618 [11]
For this case we have the following polynomial:
 -2a ^ 3b ^ 2 + 5ab ^ 5 + 7b ^ 4 + 8

 We observe that we have a polynomial of two varibles.
 Variables: a and b
 The degree of the polynomial is given by the highest sum of the exponents of the variables.
 We have then for the following term:
 5ab^5

 The sum of the exponents is:
 5 + 1 = 6

 Therefore, the polynomial is of degree 6.
 Answer:
 
the polynomial is of degree 6.
