X=-48 and y=-13
substitute the first equation into the second. you will get 2(0.25x-1)=(2/3)x+6.
that simplifies to .5x=(2/3)x+8 solve from there to get x=-48. substitute that into the first equation to get y=(-48/4)-1 therefore, x=-48 and y=-13

F(x)=2/3x+9x<br> What is the value of f(12)?
andreev551 [17]

Answer:

116

Step-by-step explanation:

To find f(12), plug in 12 as x in the equation:

f(x) = 2/3x + 9x

f(12) = 2/3(12) + 9(12)

f(12) = 8 + 108

= 116

So, f(12) = 116

Use the dot product to determine whether v and w are orthogonal.
nata0808 [166]

Answer:

B. The vectors v and w are orthogonal because their dot product is <u> 0 </u>

Step-by-step explanation:

Given that :

v=  - i - j  

w= - i + j

Therefore;

vw = ( - i - j )  ( - i + j )

Taking each  set of integer of the vector into consideration:

vw = ( -1 × - 1) ( -1 × 1)

vw = 1 - 1

vw = 0

Hence, we can conclude that :

The vectors v and w are orthogonal because their dot product is <u> 0   </u>

Describe what happens to the exponential function when the value of "k" is<br> positive. *
Schach [20]

Answer:

Step-by-step explanation:It isn’t. There are really 4 different versions of the exponential function. Positive (like the growth of money invested at 5%), negative (like the US debt constantly becoming more negative), positive decay (like the half life of a radioactive element), or negative decay ( pay half your loan amount in year 1, 1/4 in year two, 1/8 in year three, you in theory will never pay your loan completely but the debt is growing closer to zero.
