Howdy!
To do this we first have to find the unit rate of 2,600.
2,600/4=650 each week. Then, we just multiply 650x20, with 20 being the number of weeks.
650x20=13,000<---Answer

Answer:
∠CAD = 44⁰
∠ACD = 44⁰
∠ACB = 136⁰
∠ABC = 22⁰
Step-by-step explanation:
To calculate m∠CAD;
Line AD = Line DC,
thus ∠CAD = ∠ACD = ¹/₂(180 - 92°) [sum of angles in a triangle.]
∠CAD = ¹/₂ x 88 = 44⁰
Also, ∠ACD = 44⁰
To calculate m∠ACB;
∠ACB = 180 - ∠ACD [Sum of angles on a straight line]
∠ACB = 180 - 44
∠ACB = 136⁰
To calculate m∠ABC;
Line CB = Line CA
Thus, ∠ABC = ∠CAB = ¹/₂(180 - ∠ACB) [sum of angles in a triangle.]
∠ABC = ¹/₂(180 - 136)
∠ABC = ¹/₂ x 44
∠ABC = 22⁰
Lines that are parallel have the same slope, and I'm going to guess you meant y= 1/2x + 8.
So already starting we know the other equation is y= 1/2x + b. But now we have to find b.
We do this by plugging in the coordinate given.
2=1/2(-2) + b
2= -1 + b
3 = b
This means the equation you want is y= 1/2x + 3.
I hope this helps!
