Answer:
a(n) = -8n -9
a(28) = -233
Step-by-step explanation:
a(n) = a(1) + (n - 1)d
n is the nth term, a(1) is the first term, d is the common difference.
*d = -25 - (-17) = -8
a(n) = -17 + (n - 1)(-8)
= -17 + (-8n + 8)
= -17 - 8n + 8
= -8n - 9
For the 28th term
a(28) = -8(28) - 9
= -224 - 9
= -233
Answer:
1 + 2
Step-by-step explanation:
When we look at the number line, we can see that the inequality is:
x ≤ 19
This means that all values of "x", must be equal to or less than 19.
To find the correct answer choices, we must keep that equation in mind.
1. at most 19 cups - this answer choice does work, because it shows that 19 is the limit (which is what our inequality represents)
2. 19 cups or less - this answer choice works as well because it shows that 19 is the maximum and all other values of "x" must be below that.
3. more than 19 cups - this goes against our inequality, since "x" can't exceed 19. This means that this answer choice must be incorrect.
4. a minimum of 19 cups - this answer choice also cannot be correct since it shows that "x" can go over 19 (which we know is false).
5. no fewer than 19 cups - this is also wrong because it wants "x" to go over the value of 19, which it can't do.
It could be the x-axis or the y-axis (not enough information)
