Answer:

x=8,y=0

Step-by-step explanation:

y=x-8

y=8-x

So,

x-8=8-x

x+x=8+8

2x=16

x=8

Now,

y=x-8

y=8-8

y=0

yan [13]

S=2d

4s+3d=300000-80000

4s+3d=220000, now using s=2d in this equation you get:

4(2d)+3d=220000

8d+3d=220000

11d=220000

d=20000

So each daughter gets 20000 and each son gets 40000.

The image of a parabolic lens is projected onto a graph. The image crosses the x-axis at –2 and 3. The point (–1, 2) is also on

Ierofanga [76]

Answer:

$y =-\frac{1}{2}(x +2)(x - 3)$

Step-by-step explanation:

Given

$x_1 = -2$

$x_2 = 3$

$(x,y) = (-1,2)$ --- a point on the parabola

Required

The equation

First, calculate the equation from the zeros

$y =k(x - x_1)(x - x_2)$

Substitute $x_1 = -2$ and $x_2 = 3$

$y =k(x - -2)(x - 3)$

$y =k(x +2)(x - 3)$

To solve for k, we substitute $(x,y) = (-1,2)$

$2 = k(-1+2)(-1-3)$

$2 = k(1)(-4)$

$2 = -4k$

Divide by -4

$k=\frac{2}{-4}$

$k=-\frac{1}{2}$

So, the equation is:

$y =k(x +2)(x - 3)$

$y =-\frac{1}{2}(x +2)(x - 3)$

What is the answer to7/8 ÷ 4

Blizzard [7]

4 = 4/1

When dividing fractions, we follow a rule called keep, change, flip.

7/8 * 1/4 = 7/32

7/32 is the simplest form.

Answer: Third option.

Step-by-step explanation:

These are some transformations for a function f(x):

If $f(x)-k$ , then the function is shifted down "k" units.

If $f(x-k)$ , then the function is shifted right "k" units.

Knowing this we can describe the transformation from the graph of the function $f(x) = x^2$ to the graph of the function $f(x) = (x - 3)^2-1$ . This is:

The function $f(x) = (x - 3)^2-1$ is the function $f(x) = x^2$ but shifted right 3 units and shifted down 1 units.

Therefore, the correct option is the third one.
