a_sh-v [17]

Answer:

x = $ 16,000 , y = $13,000 z= $11,000

Step-by-step explanation:

given,

Investment amount $40,000

three investments yielding = $3,500

three investments are 7%, 9%, and 11%

second and third are $3,000 and $5,000 less than the first

0.07 x + 0.09 y + 0.11 z = $ 3,500

x + (x - 3000 ) + (x - 5000) = $ 40,000

3x = $48,000

x = $ 16,000

y = 16000 - 3000 = $ 13,000

z = 16000 - 5000 = $ 11,000

the investment by each

x = $ 16,000 , y = $13,000 z= $11,000

105,159 rounded to the nearest ten thousand

IceJOKER [234]

If you look at the hundereds place you see it is under the number 5 which means you would drop 1, 5, & 9 and the answer would be 105,000. If the number was above 5 you would have had to make it 106,000.

A system of linear inequalities is shown above. ( in the picture )

astraxan [27]

Answer:

C. (0, -3)

Step-by-step explanation:

The given system is

$- 2x - 3 \leqslant y$

$y - 1 \: < \: \frac{1}{2} x$

The point that satisfies both inequalities is the solution to the system.

When x=0 and y=-3.

We substitute into the first inequality to get:

$- 2(0) - 3 \leqslant - 3 \\ - 3 \leqslant - 3...true$

We again substitute into the second inequality to get:

$- 3- 1 \: < \: \frac{1}{2} (0) \\ - 4 \: < \: 0....true$

The point (0,-3) is a solution to the system of inequalities.
