A,b,d,e,f,h would be similar because they are all quadrilaterals (they all have four sides) and c,g would be the same because they are both triangles
Answer:
a. The constant = 45
b. The unit rate is 45 miles per hour
c. d = 45t
Step-by-step explanation:
a. ∵ d ∝ t
∴ d = kt
∵ d = 90 at t = 2
∴ 90 = k(2)
∴ k = 90 ÷ 2 = 45
∴ The constant of proportionality is 45
b. ∵ k = d(miles) ÷ t(hours) = 45
∴ The unit rate is 45 miles per hour
c. The equation is ⇒ d = 45t
Here is the answer that Siri gave me
Answer:
<em>y = - </em>
<em> x + 3 </em>
Step-by-step explanation:
y = mx + b
m =
and "b" is y-intercept with coordinates (0, b)
(0, 3) ⇒ <u><em>b = 3</em></u>
(4, 1), (6, 0)
m =
= -
<em>y = - </em>
<em> x + 3</em>
