Hey the answer is trinomial
It's a linear function, so you only need 2 points and then connect them together.
Easiest way: x = 0 ->y = 1 ->(0,1)
x = 1->y = 15 ->(1,15)
Answer:29.5 kilometers
Step-by-step explanation: 16.5-3.5=13 then you add 13 and 16.5
Answer:
The measure of angle DPA is 39°
Step-by-step explanation:
step 1
Find the value of x we know that arc AB+arc BC+arc CD+arc DA=360°
substitute the values
(5x+10)°+(x+1)°+3x°+(3x+25)°=360°
Solve for x
(12x+36)°=360°
12x=360°-36°
x=324°/12=27°
step 2 Find the measure of angle DPA
we know that The measurement of the external angle is the semi-difference of the arcs which comprises
m∠DPA=(1/2)[arc DA-arc BC]
arc DA=3(27)+25=106°
arc BC=27+1=28°
substitute the values
m∠DPA=(1/2)[106°-28°]=39°
-25x is the slope
-42 is the y-intercept
