HELP!!!!

Answer:

Step-by-step explanation:

You just need the distance formula here. It's very simple to follow:

$d=\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

which, for us, looks like this:

$d=\sqrt{(13-4)^2+(19-7)^2}$ and

$d=\sqrt{9^2+12^2}$ and

$d=\sqrt{81+144}$ and

$d=\sqrt{225}$ so

d = 15

Answer:

The new points to the triangle will be:

$A(-6, 6)\\B(-6, 3)\\C(-8, 3)$

Step-by-step explanation:

Because the reflection point is at $x = -1$ , all x values will subtract their distances from $x = -1$ to get their new values. The y values remain the same.

The starting values are:

$A(4,6)\\B(4,3)\\C(6,3)$

Point $A$ is 5 units away from $x = -1$ , so we'll subtract 5 from -1 to get the new x value: $-1 - 5 = -6$ , so $A(-6, 6)$ .

Point $B$ is also 5 unit away from $x = -1$ , so we'll subtract 5 from -1 to get the new x value: $-1 - 5 = -6$ , so $B(-6, 3)$ .

Point $C$ is 7 units away from $x = -1$ , so we'll subtract 7 from -1 to get the new x value: $-1 - 7 = -8$ , so $C(-8, 3)$ .

Given that y is directly proportional to x^2 and that y=2 when x=3 find the value of y when x=6

Sergio039 [100]

Answer:y=4/3

y is directly proportional to x^2 is written as

$y \alpha {x}^{2}$ introducing a constant,

y=kx^2

but from the question, when y=2 , x=3 . putting it in the formula to get the value of k

$2 = {3}^{2} \times k$

2=9k . dividing through by 9 to get the value of k

 $\frac{2}{9} = \frac{9k}{9}$ 

 $k = \frac{2}{9}$ 

putting it in the general expression

 $y = \frac{2}{9} x$ 

the value of y when x=6

 $y = \frac{2}{9} \times 6$ 

 $y = \frac{4}{3}$ 

therefore the value of y when x=6 is

4/3
