x * x = x^2
x * -3 = -3x
5 * x = 5x
5 * -3 = -15
x^2 -3x + 5x -15

Answer:
Hi there!
Your answer is:
Smallest number: 24
Median number: 25
Largest number: 26
Step-by-step explanation:
three consecutive numbers:
n, n+1, n+2
5(n+2)= (n+1+n)3 -17
5n+10= (2n+1)3-17
5n+10= 6n+3 -17
5n+10= 6n-14
-6n
-n+10= -14
-10
-n= -24
/-1
n= 24
<em><u>This</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>your </u></em><em><u>number.</u></em><em><u> </u></em><em><u>Now</u></em><em><u>,</u></em><em><u> </u></em><em><u>plug</u></em><em><u> </u></em><em><u>this</u></em><em><u> </u></em><em><u>back</u></em><em><u> </u></em><em><u>into</u></em><em><u> </u></em><em><u>your</u></em><em><u> </u></em><em><u>previo</u></em><em><u>us</u></em><em><u> </u></em><em><u>equations</u></em>
24, 24+1, 24+2
Simplify
Smallest number: 24
Median number: 25
Largest number: 26
Hope this helps
Answer:
x - 2y + 1 = 0
Step-by-step explanation:
This line goes through the points (-3, -1) and (3, 2). Going from the first oint to the second, we see that x increases by 6 (this is the 'run') and y increases by 3 (this is the 'rise'). Thus, the slope is m = rise / run = 3/6 = 1/2.
Starting with the slope-intercept form y = mx + b, we get
y = 2 = (1/2)(3) + b, or (after multiplying all terms by 2):
4 = 3 + 2b, or 1 = 2b, or b = 1/2
Then the equation of this line is y = mx + b, or y = (1/2)x + 1/2.
We must put this into standard form. Multiplying all terms by 2 yields
2y = x + 1, or x - 2y + 1 = 0
