Answer:
The amount invested are $2600 and $11400 respectively
Step-by-step explanation:
<em>Let the first amount be x</em>
Given:
(First Investment)
Principal (P1) = x
Rate (R1) = 4.5%
Time (T) = 1 year
(Second Investment)
Principal (P2) = 4x + 1000
Rate (R2) = 6%
Time (T) = 1 year
Income = $801
Calculating the income from the first investment;
Substitute values for P1, R1 and T
Calculating the income from the second investment;
Substitute values for P2, R2 and T
So:
Multiply through by 100
Collect Like Terms
Divide through by 28.5
Recall that; the second invest
Amount Invested = 4x + 1000
This gives
Hence;
<em>The amount invested are $2600 and $11400 respectively</em>
Answer:
Step-by-step explanation:
Eight friends went to a hockey game. The price admission per person was $x. This means that the total amount paid by the eight friends for admission would be
8 × x = $8x
Four of the friends paid and extra $6 each for a player guide book. This means that the total amount paid by four of the friends for the player guide book would be
4 × 6 = $24
Therefore, the expression that represents the total amount spent by the eight friends would be
8x + 24
For something to be a function, the input (x value) can only have one output (y value). If an x value has more than one y value, it is not a function.
A.) When x = 1, it has 5 y values. This is not a function
B.) -2 and -1 have two y values. This is not a function
C.) 1 and 2 have two y values. This is not a function
D.) Each input has only one output. This is a function. (Inputs can share the same outputs)
Your answer is D
