Answer:

x = 0

y = 3

Step-by-step explanation:

-x - 2y = - 6

0 - 2(3) = -6

6 = 6

-3x + 2y = 6

-3(0) + 2(3) = 6

0 + 6 = 6

PLEASE HELP!!
PSYCHO15rus [73]

<u><em>Answer:</em></u>

The bird is approximately 9 ft high up in the tree

<u><em>Explanation:</em></u>

The required diagram is shown in the attached image

Note that the tree, the cat and the ground form a right-angled triangle

<u>Therefore, we can apply special trigonometric functions</u>

<u>These functions are as follows:</u>

sin(\alpha)=\frac{opposite}{hypotenuse} \\ \\ cos(\alpha)=\frac{adjacent}{hypotenuse} \\ \\tan(\alpha)=\frac{opposite}{adjacent}

<u>Now, taking a look at our diagram, we can note the following:</u>

α = 25°

The opposite side is the required height (x)

The adjacent side is the distance between the cat and the tree = 20 ft

Therefore, we can use the <u>tan function</u>

<u>This is done as follows:</u>

tan(\alpha)=\frac{opposite}{adjacent}\\ \\ tan(25)=\frac{x}{20}\\ \\x=20tan(25) = 9. 32 ft which is 9 ft approximated to the nearest ft

Hope this helps :)

Two students Are reading a novel Ashley read 10 pages per day Carly reads eight pages per day but she starts early and is alread
iren [92.7K]

Answer:

  • P = 10D
  • P = 8D +40

Step-by-step explanation:

Ashley's page count is ...

  P = 10D

Carly's page count is ...

  P = 8D +40

_____

The page count is the product of the pages per day and the number of days. Since Carly started with a page count of 40, that is added to the product.

Need help???! Explanation too please
Natalija [7]

Answer:

When X=Y every number on either side is the same, for example 1(X)=1(Y)

Step-by-step explanation:

This is because when X=Y the X value isn't altered in any way to equal Y, so they are the same number, hope this helped!

Consider the graph of the function f(x)=2x.
77julia77 [94]

Given:

The parent function is:

f(x)=2^x

The other function is:

g(x)=2f(x)

To find:

The statement that describes a key feature of function g.

Solution:

We have,

f(x)=2^x

g(x)=2f(x)

Using these two functions, we get

g(x)=2(2)^x

Putting x=0, we get

g(x)=2(2)^{(0)}

g(x)=2(1)

g(x)=2

The y-intercept of the function g at (0,2). So, option A is correct and option B is incorrect.

We know that g(x)\to 0 as x\to -\infty and it will never intersect the line y=0. It means the horizontal asymptote of the function g is

Therefore, the correct option is A.
