The equation 38 = 9k will be true when k equals 38/9. (Do 38 divided by 9 to get k, k equals 38/9, which can't be simplified any more.)

A certain economy's consumption function is given by the equation C(x) = 0.65x + 9 where C(x) is the personal consumption expend

ipn [44]

Answer:

1) $C(0) = 9$

2) $C(50) =41.5$

3) $C(100) =74$

Step-by-step explanation:

Given : A certain economy's consumption function is given by the equation $C(x) = 0.65x + 9$

where, C(x) is the personal consumption expenditure in billions of dollars, and x is the disposable personal income in billions of dollars.

To find :

1) C(0)

Put x=0 in the given equation,

$C(0) = 0.65(0)+ 9$

$C(0) = 9$

2) C(50)

Put x=50 in the given equation,

$C(50) = 0.65(50)+ 9$

$C(50) =32.5+9$

$C(50) =41.5$

3) C(100)

Put x=100 in the given equation,

$C(100) = 0.65(100)+ 9$

$C(100) =65+9$

$C(100) =74$

-1/6 + 2/3 ( 9 + - 3/4) + - 1/2

Liono4ka [1.6K]

First simplify the section in the parenthesis.
-1/6 + 2/3(8 1/4) + -1/2
Then multiply 2/3 by 8 1/4.
-1/6 + 5 1/2 + -1/2
Add -1/2 to 5 1/2.
-1/6 + 5
Add 5 to -1/6.
4 5/6 is the fully simplified answer.
Hope this helps!
