You were right because you work backwards. so start with 80 and multiply that by 2 to get 160. Then divide that by 10 to get 16
Answer:
10 cm
Step-by-step explanation:
The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d
Using Pythagoras' identity in one of the right triangles, then
d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )
d = = 10 cm

Answer:
-6
Step-by-step explanation:
The y-intercept is represented by 'b' in the slope-intercept equation ...
y = mx +b
Solving for b, we find ...
b = y - mx
Using the given values, we find b to be ...
b = -9 -(-3)(1) = -6
The y-intercept is -6.
