Answer:
1. zeros are -2 and 1
2. zeros are -1 and 3
3. zeros are -3 and 1
4. zeros are -1
5. no zeros
6. no zeros
Step-by-step explanation:
Zeros are points on the graph that are x-intercepts; in the graph we can see that they cross -2 and 1 on the 1st equation, -1 and 3 on the 2nd equation, -3 and 1 in the 3rd equation, and -1 in the 4th equation. Since it intersects no x-intercepts in the 5th and 6th equation, it has no zeros.
Answer:
30ft
Step-by-step explanation:
2*5=10
2*4=8
2*2=4
4*2=8
10+4+8+8=30
Car A Car B
d=rt d = rt
d = ra * 2.4 d = rb 4
ra = rb+22
distances are the same so set the equations equal
ra * 2.4 =rb *4
substitue in for ra
(rb+22) 2.4 =rb *4
distribute
2.4 rb +52.8 = 4 rb
subtract 2.4 rb from each side
52.8 = 1.6 rb
33 = rb
Car b travels at 33 miles per hour
Car a = 33+22
Car a = 55 miles per hour
The answer is d because if you multiply -5.6° by 4 you will get -22.4°
