Answer:

Step-by-step explanation:

Well you only want the two equations so here they are.

x + y = -7

5*x + y = 1

I should give you the answer.

x = 2

y = -9 I think. These answers were done in my head.

Which translation for: y = (x+3)^2+4<br><br> If you can't see the picture zoom in.

Savatey [412]

Answer:

The answer is B.

Step-by-step explanation:

The original graph of y = x^2 has a vertex at (0,0)

The formula for graph translations is y = (x-#)^2+#

The number inside the parentheses is a horizontal translation.

So, we are given y = (x-(-3))^2+#

The vertex of the graph moves 3 points left, since the number is negative (-3).

The number at the end of the equation is a vertical translation.

So, we are given y = (x+3)^2+4

The vertex of the graph moves 4 points up, since the number is positive (4).

The new vertex is at (-3,4)

PLEASE HELP

lilavasa [31]

Those two functions just miss each other so there are no real solutions. Every polynomial with complex coefficients has complex solutions.

$2x^2 + 2 = 3x$

$2x^2 - 3x = -2$

$2( x^2 - \frac 3 2 x) = -2$

$x^2 - \frac 3 2 x = -1$

$x^2- \frac 3 2 x+ (\frac 3 4)^2= -1 + (\frac 3 4 )^2$

$(x - \frac 3 4)^2 = -\frac 7{16}$

$x - \frac 3 4 = \pm \sqrt{ -\frac 7{16}}$

$x = \frac 3 4 \pm \frac i 4 \sqrt{7}$

$x = \frac 1 4(3 \pm i \sqrt{7})$

Find all solutions for w by breaking the absolute value into the positive and negative components.
w = 7, -1
Hope this helps! :)
