Answer: the first one is True and the second one is false
Step-by-step explanation:
3 + 5x = 23
so replace x with 4 you get 3 + 5 * 4 = 3 + 20 = 23
this is equal to 23 so it is true
2x - 6 = 9
do the same you get
2 * 8 - 6 = 9
16 - 6 = 10
the answer is 10 not nine therefore it is false
Answer:
A. 5
Step-by-step explanation:
Parallel lines have the same slope.
present value of annuity = annual payment * [ 1 - (1+i)^-n ]/i
=>
12500 = 128.04 * [1-(1+9%/12^-n]/9%/12
=>n = 42 payments
The answer in fraction form is exactly 1/13
The approximate answer in decimal form is 0.076923
To get this answer, note how there are four cards that have "2" on them. This is out of 52 total. So we divide the values: 4/52 = 1/13. Don't forget to fully reduce as much as possible.
To go from 1/13 to 0.076923, you would use a calculator or long division
Answer:
a) see graph
b) No
Step-by-step explanation:
The given relation is
{
}
The arrow diagram is shown in the attachment.
b) The relation is not a function because -2 alone maps onto two different y-values.
One-to-many relation cannot be a function.
