Answer:

Meow Island has a linear function.

Step-by-step explanation:

Meow Island increases by multiply the input by 3 for each coordinate. On the other hand, Purr Island increases by adding 4. Linear functions increase with multiplication, not by addition, and so Meow Island increases linearly.

Answer:

$\boxed{2\pm \frac{\sqrt{2}}{2}}$

Step-by-step explanation:

$2x^2-8x=-7$

$\sf Add \ 7 \ on \ both \ sides}.$

$2x^2-8x+7=-7+7$

$2x^2-8x+7=0$

$ax^2 +bx+c=0$

$\sf Apply \ quadratic \ formula.$

$a=2 \ \ \ b=-8 \ \ \ c = 7$

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

$x=\frac{-(-8)\pm\sqrt{(-8)^2-4(2)(7)}}{2(2)}$

$x=\frac{8\pm\sqrt{64-56}}{4}$

$x=\frac{8\pm\sqrt{8}}{4}$

$x=\frac{8\pm2\sqrt{2}}{4}$

$x=2\pm \frac{\sqrt{2}}{2}$

A rectangular cracker has a length of 5 centimeters and an area f 20 square centimeters. Find its perimeter.

iren [92.7K]

Answer:

18cm

Step-by-step explanation:

We have the length of the rectangle but we need to find the width which we'll call w. Area is a, l is length.

a = l * w

20 = 5 * w

divide both sides by 5 to cancel the multiplication by 5 on the right side

4 = w

The rectangle is going to have two sides that are the length of l, and two sides that are the the length of w. We're looking for the perimiter p.

p = 2l + 2w

p = (2 * 5) + (2 * 4)

p = 18

When reflecting a figure across the x-axis, why does the y-value always change signs?

kati45 [8]

Answer:

see description

Step-by-step explanation:

When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis.

What is 520 divided by 8

erastova [34]

First see how many times can 8 go into 52. So 8 goes 6 times, and it equals to; 48
Now subtract 48 from 52; 52-48= 4

Finally bring down the 0 next to the 4; 40

Now to get you final answer find out how many times can 8 go into 40; 5
Since it goes exactly 5 times then your final answer would be; 65
Hope this helps! :)
