(whenever you have an equality and you divide each side by a negative number you have to "switch the sign")

17 - 5y < 8y -9
-13y < -26  
<span>y< 2 is incorrect , but y > 2 is the answer</span>

Give the number of real solutions,
vovangra [49]

Answer:

No real solutions.

Step-by-step explanation:

Square both sides:

x-3=(x-1)^2\\x-3=x^2-2x+1\\x^2-3x+4=0

Evaluate the discriminant:

$\Delta =3^2-4 \times 1 \times 4$

$= 9-16=-7<0$

Since $\Delta $ is less than zero, there are no real solutions.

Please someone help me solve this question

Answer:

  D.  right 4, down 8

Step-by-step explanation:

The usual transformations applied to functions are ...

  f(x) ⇒ f(x -h) . . . . translation right h units

  f(x) ⇒ f(x) +k . . . . translation up k units

  f(x) ⇒ k·f(x) . . . . . vertical scaling by a factor of k; reflection over x-axis when k < 0

  f(x) ⇒ f(x/k) . . . . . horizontal scaling by a factor of k; reflection over y-axis when k < 0

In the above, "scaling" will be expansion when |k| > 1, compression when |k| < 1.

__

Your transformation is ...

  x^2 ⇒ (x -4)^2 -8

  f(x) ⇒ f(x -4) -8

This is translation with h=4 and k=-8. That is, it is translation right 4 units and down 8 units.

_____

<em>Additional comment</em>

Like much of math, it is all about matching patterns.
