Explanation. Please Help!!!
Svetach [21]

Answer:

The domain is y > 3

Step-by-step explanation:

y = 2⁻ˣ + 3

As x approaches -∞, y approaches ∞.

As x approaches ∞, y approaches 3.

So the range is y > 3, and there is an asymptote at y = 3.

Compared to the parent function y = 2ˣ, it is reflected over the y-axis and shifted up 3 units.

The false statement is "the domain is y > 3".  Domain describes the possible values of x.  Range describes the possible values of y.

Seven times the smaller of two numbers added with two times the larger number is 635. While seven times the larger number decrea
Mandarinka [93]

Answer:

Step-by-step explanation:

x = smaller number, y = bigger number

7x + 2y = 635

7y - 2x = 871....rearrange...-2x + 7y = 871

7x + 2y = 635....multiply by 2

-2x + 7y = 871...multiply by 7

----------------------------------

14x + 4y = 1270 (result of multiplying by 2)

-14x + 49y = 6097 (result of multiplying by 7)

--------------------------------add

53y = 7367

y = 7367/53

y = 139

7x + 2y = 635

7x + 2(139) = 635

7x + 278 = 635

7x = 635 - 278

7x = 357

x = 357/7

x = 51

solution : x = 51 and y = 139 or (51,139)

Can someone help this one is really throwing me off? Thanks
Anna007 [38]

These given angles are vertically opposite which means their measure is equal. Let's find x with the help of the equation..~

\sf3x - 5 = 145

Move the constant to the right-hand side and change its sign

\sf \: 3x = 145 + 5

Add the numbers

\sf \: 3x = 150

Divide both sides of equation by 3

\boxed{ \tt \: x = 50}
