What is the answer to this question 2(3x-5)+3(2x+3)

12x-1

Step-by-step explanation:

Do distributive property then add like terms.

6x-10+6x+9

12x-1

x=-1  (1)

Step-by-step explanation:

you need to use distributive property, 2 times 3x equals 6x, 2 times 5 equals 10. 3 times 2x equals 6x,  3 times 3 equals 9.

6x-10+6x+9

what you do to one side you need to do to both so-10 + 10 equals 0 then 9 minus 10 equals -1. 6 minus 6 equals 0, 6 - 6 0 again.

x=-1  (1)

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
