Answer:
$10,000 invested in CD
$18,000 invested in money market
Step-by-step explanation:
<u>Complete Question:</u>
<em>Jorge invested $28,000 into two accounts. The amount he put in his money market account was $2,000 less than twice what he put into a CD. How much did he invest in each account?</em>
Let money put in CD be x
So
Money put in money market will be 2x - 2000
Alltogether, that is 28,000. Thus, we can write:
x + (2x-2000) = 28,000
Solving, we get:
x + (2x-2000) = 28,000
x + 2x - 2000 = 28,000
3x = 30,000
x = 30,000/3 = 10,000
$10,000 invested in CD
We know 2x - 2000 invested in money market, so:
2(10,000) - 2000 = $18,000 invested in money market
First, let's define your variables!
x=cost of tickets for adults
y=cost of tickets for kids...
You know that they sold 900 tickets, which means the combination of x and y equals 900.
Therefore one equation is...
x+y=900
We also have to take care of the second equation...
We know that 13x represents the total cost of ADULT tickets
We know 7y represents the total cost for the children...
Which means...
13x+7y=11000
There are you equations! (bolded)

Answer:
(x - 3)² + (y + 4)² = 90 or [3√10)²
Step-by-step explanation:
We need to calculate the radius of this circle. To do this we calculate the distance from the center (3, -4) to the point (6, 5).
As we move from (3, -4) to (6, 5), x (the run) increases by 3 and y (the run) increases by 9. Thus, the distance between these points, according to the Pythagorean Theorem, is
r = √[3² + 9²], or r = √90, or r = 3√10.
Using the standard equation of the circle, (x - h)² + (y - k)² = r², we obtain
(x - 3)² + (y + 4)² = 90 or [3√10)²
Answer:
<h2>Option A, C and D is the three possible solution.</h2>
Step-by-step explanation:
Each Television earns $72 and each Computer earns $90.
The manager’s target is to make at least $360.00 a day.
It is <u>not clarified the exact number of Televisions and Computers</u>.
Hence, as per the given condition, 
.
Now we just need to check the given options, whether they satisfy the above equation, or not.
Except the option B, each inequality indicates a value greater than 360.
Hence, option B can not be the possible solution.
