Beginning with the equation 2x + 8y = 12, write an additional equation that would create:

kramer

Answer:

[see below]

Step-by-step explanation:

A system of equations with no solution would show parallel lines. We just have make a equation that is parallel to the original equation.

The slope of 2x + 8y = 12 is $-\frac{1}{4}$ , and it's y-intercept is $\frac{3}{2}$ .

Since parallel lines have the same slope but not the same y-intercept, I would use $y=-\frac{1}{4}x+3$ .

Any equation that has -1/4 as the slope would work.

When graphed together, they show as a system with no solution.

Hope this helps.

Factorize the following: <br>49x² - 25

creativ13 [48]

Answer:

(7x+5)(7x-5)

Step-by-step explanation:

We can use the difference of squares equation which states that when a number is multiplied like: (ax+b)(ax-b) then it equals (ax-b). In this equation, since there is no "b" in the typical ax^2+bx+c, we can recognize that the answer is not a square, but a difference of squares.
