Which algebraic expression is a polynomial? 3m2n-2m/n+1/n

Lesechka [4]

Answer:

d) $7mn+\frac{3m}{2}+\frac{5n}{4}$

Step-by-step explanation:

Which algebraic expression is a polynomial?

$a)3m^2n-\frac{2m}{n}+\frac{1}{n} \\b)\frac{2mn}{5}-\frac{\sqrt{m} }{4} +4m^5\\c)\frac{4m^3}{n^2}-3mn^5+\sqrt{8}\\d)7mn+\frac{3m}{2}+\frac{5n}{4}$

Answer: A polynomial is an expression with variables and coefficients separated by addition and subtraction. The following are used when determining if an expression is a polynomial:

i) Variables of a polynomial must not have negative exponent.

ii) Variables of a polynomial must not have fractional exponent.

iii) Dividing by an exponent is not allowed

iv) Exponent radicals are not allowed.

a) $3m^2n-\frac{2m}{n}+\frac{1}{n}$ is not a polynomial because dividing by an exponent is not allowed.

b) $\frac{2mn}{5}-\frac{\sqrt{m} }{4} +4m^5$ , is not a polynomial because exponent radicals are not allowed (√m)

c) $\frac{4m^3}{n^2}-3mn^5+\sqrt{8}$ is not a polynomial because dividing by an exponent is not allowed.

d) $7mn+\frac{3m}{2}+\frac{5n}{4}$ is a polynomial

Write the equation of a line that passes through points (0,4) and (-2,-3) in slope intercept form

Otrada [13]

y=mx+b is the equation of a line;

m=slope , b= y-intercept

You can find the slope with this following equation: (y(2)-y(1))/(x(2)-x(1))

In this case the points are (0,4) and (-2,-3). The first set being (0,4) and the second (-2,-3). This means (0,4) can be expressed as (x(1),y(1)) and (-2,-3) expressed as (x(2),y(2)). Plugging these numbers into the slope equation gives us: (-3-4)/(-2-0) = -7/-2 = 7/2.

m= 7/2 ; so we have : y= (7/2)x+b

We are give a set of points which it passes through, we can simply plug them in:

4 = (7/2)(0)+b (0 is the x and 4 is the y)

We get 4 = 0 +b .... 4=b

our final equation is : y=(7/2)x+4
