The equation intersecting these two points is:
y = -2x + 7
When x = -4, y = 15
When x = 2, y = 3
Answer:
(3,6) ( 1,0)
Step-by-step explanation:
In this number 800 is 10 times
as much as what number.
To answer the query we can
illustrate this problem into a mathematical equation of
<span><span>
1.
</span>10 x N = 800</span>
<span><span>
2.
</span><span> 10N = 800</span></span>
<span><span>3.
</span><span> N = 800/10</span></span>
<span><span>
4.
</span><span> N = 80</span></span>
Hence, the number is 80.
Answer:
Around 25 pages / 1.5 minute(s)
Step-by-step explanation:
18 / 12 = 1.5 minutes per paper.
So, 18 + 18 = 36 + 1 = 37 minutes
12 + 12 = 24 + 1 = 25
37 / 25 = 1.5
