Multiply the bottom equation by 2 and you'll get

4x + 2y = 12
2x - 2y = 6

Then combine the two equations and the y's will cancel out and you'll get

6x = 18

Divide by 6.

x = 3

4x+2y = 12
x+ y = 3
Times the bottom one by -2
4x+2y=12
2x-2y=-6
Cancel out the 2y and -2y and add 4x and 2x, 12 and -6 together
6x=6
divide by 6 for x
x=1
your answer is 1

Find the equation of the line passing through the points (1, -2) and (-2, 7). Write the equation in slop-intercept from.

alex41 [277]

Y=-3x+1 because in the points the equation will be y+2=-3(x-1) this converted into slope intercept form is y=-3(x-1)

What are the roots to<br> the equation<br> 2x² + 6x-1=0?

lys-0071 [83]

Answer:

The roots of equations are as m = $\frac{-3}{2} + \frac{\sqrt{11} }{2}$ And n = $\frac{-3}{2} - \frac{\sqrt{11} }{2}$

Step-by-step explanation:

The given quadratic equation is 2 x² + 6 x - 1 = 0

This equation is in form of a x² + b x + c = 0

Let the roots of the equation are ( m , n )

Now , sum of roots = $\frac{ - b}{a}$

And products of roots = $\frac{c}{a}$

So, m + n = $\frac{ - 6}{2}$ = - 3

And m × n = $\frac{ - 1}{2}$

Or, (m - n)² = (m + n)² - 4mn

Or, (m - n)² = (-3)² - 4 ( $\frac{ - 1}{2}$ )

Or, (m - n)² = 9 + 2 = 11

I.e m - n = $\sqrt{11}$

Again m + n = - 3 And m - n = $\sqrt{11}$

Solving this two equation

(m + n) + ( m - n) = - 3 + $\sqrt{11}$

I.e 2 m = - 3 + $\sqrt{11}$

Or, m = $\frac{-3}{2} + \frac{\sqrt{11} }{2}$

Similarly n = $\frac{-3}{2} - \frac{\sqrt{11} }{2}$

Hence the roots of equations are as m = $\frac{-3}{2} + \frac{\sqrt{11} }{2}$ And n = $\frac{-3}{2} - \frac{\sqrt{11} }{2}$ Answer

What is the side length of a cube with a volume of 2197 cm3?

Nataliya [291]

The side length of a cube would be the cube root of its volume, because it's length, width and height are all the same. So the answer is 13

Complete the two-column proof by providing a reason for each of the five statements.

koban [17]

I will only be writing the reasons for each and you can respond if you need clarification for anything:

1. given

2. opposite sides of a parallelogram are congruent (and a rectangle is a parallelogram so the properties apply)

3. def rectangle

4. SAS (side angle side congruence theorem)

5. CPCTC (congruent parts of congruent triangles are congruent)
