Answer:
y = 0x +3 or just y = 3
Step-by-step explanation:
m= 3-3/-6-4
= 0/-10 = 0
3= 0(4) +b
3=b
Answer:
Given
This is our initial premise.
2) Linear pairs of angles are supplementary
This one is a little questionable, as some definitions of linear pairs require supplementary angles, whereas others only require the intersection of two lines. Check your book or notes for any given theorems regarding supplementary angles.
3)

The definition of supplementary angles is that two angles are supplementary if their measures sum to
180
∘
.
4) Substitution of 1. into 3.
As with 2), this may differ based on the teacher or book. Some may prefer that you write out the equation, whereas others may be satisfied with the references as given. Check for similar examples.
5)

Subtracting

from each side of 4. gives us the above result.
6) Definition of right angle
Step-by-step explanation:
Max height is the vertex
convert to vertex form (y=a(x-h)^2+k) by completeing the square
h(t)=-16(t²-4t)+80
h(t)=-16(t²-4t+4-4)+80
h(t)=-16((t-2)²-4)+80
h(t)=-16(t-2)²+64+80
h(t)=-16(t-2)²+144
vertex is (2,144)
at t=2, the height is 144
max height is 144ft
Answer:
(2P + G) feet/min
Step-by-step explanation:
Speed of the panda = P
Speed of the giraffe = P + G
Thus,
Speed of Panda + Speed of Giraffe = approaching time
= P + P + G
= <u>2P + G</u>
Thus, The panda and the giraffe are approaching each other at a rate
of <u>(2P + G) ft/min</u>
<u></u>
