As with any linear equation of this sort, divide by the coefficient of the variable.
.. 470 h = 3008
.. (470 h)/470 = 3008/470
.. h = 3008/470 = 6.4
(-30 km/h) -(45 km/h) = -75 km/h . . . . . east is positive here
The velocity changed 75 km/h to the west.
See explanation below
Explanation:
The equation: 4x + 3y = -12
To plot the graph using the intercept, we need to find the y and x intercept
To get the y intercept, we replace x with 0
4(0) + 3y = -12
0 + 3y = -12
3y = -12
divide both sides by 3:
3y/3 = -12/3
y = -4
To get the x intercept, we will replace y with 0
4x + 3(0) = -12
4x + 0 = -12
4x = -12
divide both sides by 4:
4x/4 = -12/4
x = -3
Plotting the x and y intercept on the graph:
The last one......y=1/2x + 8
Answer:
He rode 2 miles.
Teresa is right.
Step-by-step explanation:
1/4 = 0.25
0.25 x 8 = 2
