Answer:

Step-by-step explanation:
we know that
The total vertical distance (total miles North) traveled is equal to

Remember that


substitute


Answer:
slope=0
Step-by-step explanation:
Slope (m) = ΔY
/ΔX
=0
ΔX = -3 – 6 = -9
ΔY = 8 – 8 = 0
Distance (d) = √ΔX2 + ΔY2 = √81 = 9
Equation of the line:
y = 0x + 8
When x=0, y = 8
Answer:
0.6820
Step-by-step explanation:
Given data
Angle= 47°
Hence we want to find
cos 47°
From calculator
cos 47°=0.681998
to 4 dp
0.6820

Answer: The answer is (22, 15).
Step-by-step explanation: Given that 'x' represents the number of cars Leonard has and 'y' represents the number of cars Liam has.
Then, according to the given information, we have

Multiplying the first equation by 2 and adding to the second equation, we have

So,

Therefore, Leonard has 22 cars and Liam has 15 cars.
Thus, (22, 15) is the solution to the given system.
