Answer:

D. 100.

Step-by-step explanation:

-m + 0.02 + 2.1m = -1.45 -4.81m

Multiply by 100:

-100m + 2 + 210m = -145 - 481m

What type of polynomial is 3x+x to the second power +4
mina [271]

The answer is quadratic.


A quadratic equation takes this form:


<em>ax^2+ bx + c</em>


The "a,""b,"and "c" represent numerical coefficients.


This is how your equation looks:


3x + x^2 + 4


Now it is standard that we organize the polynomial in descending order so it will look like this:


x^ 2 + 3x + 4


(commutative property of addition says that the arrangement will not affect the result)


It matches the quadratic polynomial form.


<em>* You might be thinking, x to the second power has no number next to it though, well actually it does. The numerical coefficient of x to the power of two in this case is actually 1. It's just that in math, it is not necessary to put the one anymore. It is already assumed. </em>

Write an equation of the line parallel to 3x + 5 = 2y that has a y-intercept of -1
denpristay [2]

Answer:

3x - 2 = 2y

Step-by-step explanation:

The equation of a line in slope- intercept form is

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

Rearrange 3x + 5 = 2y into this form by dividing all terms by 2

\frac{3}{2} x + \frac{5}{2} = y ← in slope- intercept form

with slope m = \frac{3}{2}

Parallel lines have equal slopes and c = - 1, thus

y = \frac{3}{2} x - 1 ← in slope- intercept form

Multiply through by 2

2y = 3x - 2 ← equation of line
