What is y=4/5x+2 written in standard form
shepuryov [24]

Answer:

4x-5y=-10

Step-by-step explanation:

we know that

The equation of the line in standard form is in the form

Ax + By = C

where

A is a positive integer, and B, and C are integers

In this problem we have

y=\frac{4}{5}x+2 ----> equation of the line in slope intercept form

Convert to standard form

Multiply by 5 both sides

5y=4x+10

4x-5y=-10

Evaluate. –1.65 + (–3.4)
elena55 [62]
Hey there! 

This seems like a algebraic expression

SO,
Remember: negative and negative = positive
                      positive and positive = positive
                     positive and negative = negative
                       negative and positive = negative

In this problem we will be doing negative and negative so that means our answer will be a negative 

Firstly, lets line up our decimals to solve this problem (once when you do that , you can solve it easier)

-1.65 &#10;\\ +&#10;\\ (-3.4)&#10;

Answer: 
-5.05

Good luck on your assignment and enjoy your day

Step-by-step explanation:

6. The fraction can be written as;

\frac{x^2}{2y} /\frac{y^2}{4} \\\\\frac{x^2}{2y} *\frac{4}{y^2} \\\\

Divide 4 by 2

=\frac{2x^2}{y^3}

7.

The fraction can be written as;

\frac{b^2}{6} /\frac{b}{a}

introduce product sign as

\frac{b^2}{6} *\frac{a}{b} \\\\=b*a/6\\=\frac{ab}{6}

8.

The fraction can be written as;

\frac{x}{y} /\frac{yx}{2}

Introduce product sign

\frac{x}{y} *\frac{2}{yx} \\\\=\frac{2}{y^2}

9.

The fraction can be written as;

\frac{x}{y^2} /\frac{x}{y} \\\\\\=\frac{x}{y^2} *\frac{y}{x} \\\\\\=\frac{1}{y}

10.

The fraction is simplified to;

\frac{x}{3y} /\frac{9}{x} \\\\\\\frac{x}{3y} *\frac{x}{9} =\frac{x^2}{27y}
