Answer:
sqdance can solve this one easily
Step-by-step explanation:
41.2%
percent change = ((new value) - (old value))/(old value) × 100%
... = (634,000 -449,000)/(449,000) × 100% . . . . fill in given values
... = 185,000/449,000 × 100% . . . . . . . do the subtraction
... ≈ 0.412027 × 100% . . . . . . . . . . . . . . do the division
... = 41.2027% ≈ 41.2% . . . . . . . . . . . . . do the multiplication
3(3x+1) (2x-1)
18x^2 -3x-3
Factor out a 3
3(6x^2 -x-1)
ok so for the 2 ft pillows the perimeter would be 8 ft and for the 1 ft pillows the perimeter would be 3 ft. So you would need 8(2)+3(3)=16+9=25 so she needs 25 feet of trimming.
C.y = 3x + 4
We have two points, so we can find the slope
m = (y2-y1)/ (x2-x1)
= (7--2)/ (1--2)
= (7+2)/(1+2)
= 9/3
=3
The slope is 3
We can find the point slope form of the line
y-y1 = m(x-x1)
y-7 = 3(x-1)
Distribute
y-7 =3x-3
Add 7 to each side
y-7+7 = 3x-3+7
y = 3x+4
This is in slope intercept form (y=mx+b)
