(a) The rate that the point 8,28 represents is 3.5 cm/s since 28/8 = 3.5
(b) The unit rate is 3.5 cm/s since the rate is constant.
(c) The two points lie on the same line and that both points results to a rate of 3.5 cm/s.<span />
Answer:
∠B = 41°
Step-by-step explanation:
∠BCD is an exterior angle of the triangle
The exterior angle is equal to the sum of the 2 opposite interior angles, thus
∠A + ∠B = 113
72 + ∠B = 113 ( subtract 72 from both sides )
∠B = 41°
Answer:
y = 6.5
Step-by-step explanation:
Using a ratio
10 13
----- = -----------
10+5 13+y
10 13
----- = -----------
15 13+y
Using cross products
10(13+y) = 13*15
10(13+y) = 195
130+10y = 195
Subtract 130 from each side
10y = 65
Divide by 10
y = 65/10
y = 6.5
Answer:
y = -0.5x + 3
