Step-by-step explanation:
Amount of money spend in 1 day = x
So, amount of money spend in 7 days = (7x)
⇒ Amount of money spend in 1 week = (7x)
Amount of money saved in 1 week = y
∴ Income in 1 week = (7x + y)
So, income in 3 weeks = [3 x (7x + y)]
= (21x + 3y)
First what your gonna do is find the slope. So y2-y1/x2-x1 so 17-12/220-120= 5/100 so 1/20. Then you have to put that into slope intercept form. So y=1/20x + b. Then plug in points for x and y. I’ll use 12 and 120. So 12 = 1/20(120)+ b = 12=6+b then subtract 6 from both sides to get b= 6. So your answer is y= 1/20x +6
It seems like you already have it but you haven't done the work all the way through yet. anyway Here:

Answer:
58 square units
Step-by-step explanation:
Take the shaded figure as a full larger rectangle minus the rectangular part which is not shaded.
Area of the full larger rectangle:
Area = length × width
Length = |12 - 2| = 10 units
Width = |8 - 1| = 7 units
Area = 10 × 7 = 70 units²
Area of the unshaded small rectangle:
Length = |10 - 4| = 6 units
Width = |3 - 1| = 2 units
Area = 6 × 2 = 12 units²
Area of the shaded figure = 70 - 12 = 58 square units
