Answer:
y = -4x + (-2)
Step-by-step explanation:
if you plug in the x values in the equation it equals y
Use the distributive property:
5*b+5*2+b=20
5b+10+b=20.
Combine like terms:
6b+10=20.
Subtract 10 from both sides:
6b+10-10=20-10
6b=10.
Divide both sides by 6:
6b/6=10/6
b=5/3=1 2/3.
Brian travels 1 2/3 hours. This means Annie travels
5(1 2/3+2)=5(3 2/3)=5(11/3)=55/3=18 1/3 hours.
Hope this helps!

- Sum of Angles: 180(n - 2)°
Step-by-step explanation:
<u>Step 1: Identify</u>
We have a polygon, so n = 4.
- Substitute [SA]: 180(4 - 2)°
- (Parenthesis) Subtract: 180(2)°
- Multiply: 360°
This tells us the sum of all angles in the shape.
<u>Step 2: Solve for </u><em><u>x</u></em>
- Set up equation: 90° + 93° + 89° + x° = 360°
- Combine like terms: x° + 272° = 360°
- Isolate <em>x</em>: x = 88°
