I need help with this problem. <br>

Zina [86]

Answer:

(1,4)

Step-by-step explanation:

Let's this of $y=\sqrt{x}$ which is it's parent function.

How do we get to $y=-\sqrt{x-1}+4$ from there?

It has been reflected about the a-axis because of the - in front of the square root.

It has been shifted right 1 unit because of the -(1) in the square root.

It has been moved up 4 units because of the +4 outside the square root.

In general:

$y=a(x-h)^2+k$ has the following transformations from the parent:

Moved right h units if h is positive.

Moved left h units if h is negative.

Moved up k units if k is positive.

Moved down k units if k is negative.

If $a$ is positive, it has not been reflected.

If $a$ is negative, it has been reflected about the x-axis.

$a$ also tells us about the stretching factor.

The parent function has a starting point at (0,0). Where does this point move on the new graph?

It new graphed was the parent function but reflected over x-axis and shifted right 1 unit and moved up 4 units.

So the new starting point is (0+1,0+4)=(1,4).

Which expression can be written as k square root 3 where k is an integer

Damm [24]

Answer:

A simple expression is $\sqrt{48}$ = 4 $\sqrt{3}$

Step-by-step explanation:

Surds are irrational numbers expressed with respect to a square root. There are some basic rules required when dealing with surd.

Integers are numbers that do not have a decimal or fractional part i.e whole numbers. So, a simple expression that can be written as k square root 3 where k is an integer is $\sqrt{48}$ .

So that,

$\sqrt{48}$ = $\sqrt{16 * 3}$

= 4 $\sqrt{3}$

What is the y-intercept for 10x+4y=20

stiv31 [10]

Answer:

Step-by-step explanation:

Hi,

find the x- and y-intercepts:

10x + 4y = 20

finding x-intercept when y = 0

10x = 20

x = 2 Pt(2,0) the x intercept

finding y-intercept when x = 0

4y = 20

y = 5 Pt(0,5) the y intercept

What's the expression for the sum of two and the quotation of a number x and five ??

7nadin3 [17]

X + x = 2
1 × 5 = 5
So it would be blank plus blank gives you x=2
Then blank times blank gives you x=5

PLZ HELP I WILL MARK BRAILNLEIST!! 20. b) Find the side length of the square. [No label is required.] *

iogann1982 [59]

Answer:

The length of one side is 13 feet.

Step-by-step explanation:

To start, a square is 4 sides that are equal in length. This means that when you have a problem like this, you need to set the equations equal to each other like:

$2x+5=6x-11$

In order to solve a problem like this, with the same variables on different sides, start by subtracting the smaller variable from both sides. In this case, you would be subtracting 2x from both sides, which would leave us with:

$5=4x-11$

After that, you solve it like a normal one-step equation. Add 11 to both sides.

$16=4x$

Now, divide both sides by 4 and you will know how much $x$ is worth.

$4=x$

Now that we know how much $x$ is worth, we can plug that into either of the equations given to us. It doesn't matter which since they are equal to each other.

$2(4)+5$

That would give us 13.
