Answer:

x = 3/2 | y = -3

Step-by-step explanation:

Given equations:

  • y = 2x - 6. . . .(i)
  • y = -4x + 3. . . . (ii)

Substituting from equation (i) for y:

==> 2x - 6 = -4x + 3

==> 2x + 4x = 6 + 3

==> 6x = 9

<em>dividing both </em><em>sides by 3</em><em>:</em>

==> 2x = 3

==> x = 3/2

Substituting 3/2 for x in equation (i):

==> y = 2(3/2) - 6

==> y = 3 - 6

==> y = -3

How do you solve 6) n2+7n+15=5 by factoring?
charle [14.2K]
First, you need to set the equation equal to zero:

n^2 + 7n + 10 = 0

Now we factor. We need to find two numbers that add up to 7 and multiply to 10. 

2 + 5 = 7
2 * 5 = 10

Now, we just need to write this as a polynomial:

(n + 2) (n + 5)
is our answer. 

Hope this helps!

Triangle EFG has vertices E(-3,1), F(1,1), and G(4,5). Find the coordinates of the image of point of E after a translation of 3
torisob [31]

Answer:

E(-1,3) F(3,-2) G(6,2)

Step-by-step explanation:

It's just simple addition and subtraction. The x-coordinate would add 2 since it is going to the right, which is positive. The y-coordinate would subtract 3 since going down be negative.

Anyone know how to expand 5p(p-3)
Katyanochek1 [597]
I believe what your asking is just multiplying it together so 5p(p-3) would be 5p2-15p. the p2 is p squared or a little 2 on top of the p. Hope I helped!

Please help!!!!

Answer:

Step-by-step explanation:

From the figure attached,

If the figures shown are congruent (Equal in shape and size), length of all the sides must be equal.

Therefore, sides sides CD and GH must be equal in measures.

Distance between the two points (x_1,y_1) and (x_2,y_2) is given by,

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Length of the side CD having ends C(-4, 4) and D(0, 5) will be,

CD = \sqrt{(-4-0)^2+(4-5)^2}

CD = \sqrt{(16+1)}

     = \sqrt{17}

Length of GH having ends G(0, -4) and H(4, -5) will be,

GH = \sqrt{(0-4)^2+(-4+5)^2}

      = \sqrt{16+1}

      = \sqrt{17}

Therefore, m(CD) = m(GH)

Similarly, we can prove all corresponding sides of two figures equal in measure.

This shows ABCD ≅ EFGH.
