In your notebook, set up the following subtraction in a vertical format and select the correct answer. Reduce 7y 2y 2 - 7 by 3 -

Elodia [21]

The reduction from of the equation is $\rm -2y^2+11y-10$ .

<h2>Given that</h2>

Reduce the equation; $\rm 7y +2y ^2 - 7$ by $\rm 3 - 4y$ .

<h3>According to the question</h3>

To reduce the given equation follow all the steps given below.

Reduce the equation; $\rm 7y +2y ^2 - 7$ by $\rm 3 - 4y$ .

To reduce the equation means we need to subtract one equation from another.

Then,

The reduction from the equation is,

$\rm =7y-2y^2-7-(3-4y)\\
\\
= 7y-2y^2-7-3+4y\\
\\
= 11y-2y^2-10\\
\\
= -2y^2+11y-10$

Hence, the reduction from of the equation is $\rm -2y^2+11y-10$ .

Answer:

4300 $\frac{67}{1000}$

Step-by-step explanation:

evaluate each part

4 × 1000 = 4000

3 × 100 = 300

6 × $\frac{1}{100}$ = $\frac{6}{100}$ × $\frac{10}{10}$ = $\frac{60}{1000}$

7 × $\frac{1}{1000}$ = $\frac{7}{1000}$

Thus

4000 + 300 + $\frac{60}{1000}$ + $\frac{7}{1000}$

= 4300 $\frac{67}{1000}$

Y = -2x + 1 4x + y = 9

Answer:

(4, -7)

Step-by-step explanation:

Maybe you want the solution to this system of equations.

About the easiest way to obtain it is to use a graphing calculator.

(x, y) = (4, -7)

_____

<em>Additional comment</em>

Since one of the equations gives an expression for y, it is a simple matter to substitute that for y in the other equation.

4x +(-2x +1) = 9

2x = 8 . . . . . . . . . . subtract 1 and simplify

x = 4

y = -2(4) +1 = -7 . . . use the first equation to find y
