50d^2 - 98e^2

Factor out 2.

2(25d^2 - 49e^2)

We now factor the difference of two perfect squares within the parentheses.

2(5d - 7e)(5d + 7e)

This is as far as we can factor.

Done!

Choose the equations that are not linear equations. - x - y = 2, x^2 + y = 4, x/2 - y^3 = 1, x = 5
tekilochka [14]

Answer:

  • x^2 + y = 4
  • x/2 - y^3 = 1

Step-by-step explanation:

Any equation with a product of variables, or with a variable in an exponent or denominator, is <em>not a linear equation</em>. Here, "product of variables" includes powers and roots—any expression with an exponent other than 1, or a total of exponents other than 1.

Line m includes the points (-3, 3) and (-4,-6). Line n has the same slope as line m and
Sveta_85 [38]

For this case we have that by definition, the equation of a line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

The slope of a line is given by:

m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}

We have that the line m passes through the following points:

(x_ {1}, y_ {1}): (-3,3)\\(x_ {2}, y_ {2}): (-4, -6)

So, the slope of the line m is:

m = \frac {-6-3} {- 4 - (- 3)} = \frac {-9} {- 4 + 3} = \frac {-9} {- 1} = 9

Line n has the same slope so the equation is of the form:

y = 9x + b

We have as data that the y-intercept is -\frac{2} {3}. Thus, we have that the equation of line n is:

y = 9x- \frac {2} {3}

ANswer:

y = 9x-\frac {2} {3}
