Answer:
170 km/h
Step-by-step explanation:
This problem is represented in the Figure below. So, we can find the components of each vector as follows:
Therefore:
So:
Finally, the magnitude is:
Slope-intercept form: y = mx + b
(m is the slope, b is the y-intercept or the y value when x = 0 --> (0, y) or the point where the line crosses through the y-axis)
Since you know:
m = -2
b = 5 Substitute/plug it into the equation
y = mx + b
y = -2x + 5
U multiply it as u would multiply a two digit and a one digit number step by step only then u have to multiply the second number like u did to the other number and u add a zero then add them and u get ur answer
