When the following expression is written in simplest form, what is the coefficient of the variable term? -2.5y + 8y - 10.5y -5 5.5 0 -21

-5

Step-by-step explanation:

-2.5y + 8y - 10.5

= 5.5y - 10.5y

= -5y

The coefficient of the variable y is -5.

-5

Step-by-step explanation:

Option 1 is correct. -5

Step-by-step explanation:

Given:The given expression is.

Write the given expression in simplest form.

Add negative term of y.

The simplest form of given expression is

Therefore, the coefficient of the variable term is -5

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

the answer is y < -3 or   y > 3

-3y > 7 + 2

-3 y > 9

y < -3
