Well... if 450 is 90% of the crates then 500 is 100%. 450 crates is 0.90% of 500 crates.
The slope point form is

m is the slope
x1, y1 are the coordinates of a point on the line
The slope of the line is -1
m = -1
point (-5, -4) lies on the line
x1 = -5 and y1 = -4
Let us substitute them in the form above

Remember (-)(-) = (+)

The equation of the line in the slope-point form is y + 4 = -1(x + 5)
Answer:
13
Step-by-step explanation:
Let the number be x.
ATQ x+22=455/x. x^2+22x=455. x=-35 or 13. Since x is positive, x=13
15.48 + 5.16 = p because you have to do the reverse. to find "p" you have to add the amount you subtracted.
6y - 4(y - 1) +6
6y - 4y -4(-1) + 6
6y - 4y +4 + 6
2y + 10
