Step-by-step explanation:
slope = 2-4/2-1 = -2
y - 2 = -2(x - 2)
y-2 = -2x +4
y = -2x + 6
Let a_1 = 5
Let d = 5 = common difference
S_n = a_1 + (n - 1)d
S_n = 5 + (n - 1)4
Answer:
3*10^4. Hope this helps!
Step-by-step explanation:
This is the concept of algebra, we are required to find a number,x, such that 87 decreased by three times a number is great than one hundred and sixty-five.
Supposed the number is x, three times the number will be:
3*x=3x
thus;
87-3x≥165
-3x≥165-87
-3x≥78
dividing both sides by -3 we get:
(-3x)/(-3x)≥78/(-3)
x≤-26
This implies that the number is less than or equal to 26
Answer: the answer is 168
