X^3+4x^2+5x+2 is the answer
The third one, this is because you take your y2 and y1 values (y2=0 and y1=9 because these are the two y values given to you from each coordinate) and subtract 0-9. then you do the same, but with the x2 and x1 values. so your x1 value is 3 and your x2 value is 0, so you subtract 0 from 3. divide your second answer from the first answer, to get a gradient of -1/3 x. now using the first coordinate (0,9) you know that the y coordinate is 9. as the x value =0, we know that the line is passing through the y axis at 9 so 9 is your y intercept. this gives you the equation -1/3x+9. hope this helped and wasn't too confusing!

_____________
Answer:
x = -6
Step-by-step explanation:
Let the number be x
<u>Condition:</u>
=> 10-3x = x+22
<u><em>Let's Solve it:</em></u>
=> -3x-x = 22-10
=> -2x = 12
<em>Dividing both sides by -2</em>
=> x = -6
4 big mice and 3 small mice because 4 X 25=100; 3 X 10=30
100+30=130
is that right?
