Answer:
See explanation below.
Step-by-step explanation:
Take the original number and move the decimal from right to left, one place at a time. Stop just next to the last number, and count the number of times you moved the decimal. The number of times it moved is the exponent of 10. See examples below:
285 is the same as 2.85 x 10^2
3721 is the same as 3.7 x 10^3
88700000 is the same as: 8.87 x 10^7

Find the slope using the formula [ y2-y1/x2-x1 ].
-9-(-12)/-15-(-24)
3/9
1/3
Find the y-intercept using the formula [ y = mx + b ].
y = 1/3x + b
-12 = 1/3(-24) + b
-12 = -8 + b
-4 = b
Use (18, 2) to see if the line passes through it
y = 1/3x - 4
2 = 1/3(18) - 4
2 = 6 - 4
2 = 2 TRUE
Thus, the line does pass through (18, 2).
Best of Luck!
Answer:
n² + 3n +1
Step-by-step explanation:
n(n+1) + 2n + 1
<h3>i) distribute n into the parantheses</h3>
= (n×n) + (n×1) + 2n + 1
= n² + n + 2n + 1
<h3>ii) collect like terms</h3>
= n² + 3n +1
