Answer: velocity-time graph
Step-by-step explanation: The principle is that the slope of the line on a velocity-time graph reveals useful information about the acceleration of the object. If the acceleration is zero, then the slope is zero (i.e., a horizontal line). If the acceleration is positive, then the slope is positive (i.e., an upward sloping line).
Answer: option C is the correct answer
Step-by-step explanation:
The y-intercept of the function is the point on the y or vertical axis at which the straight line cuts through it. The value on the y axis is read off as the y-intercept .
The equation of a straight line is modelled using the slope - intercept equation of
y = mx + c
Where m is the slope( change in value of y/ change in value of x.
c = the y-intercept
Looking at the function given,
f(x)=4 – 5x? Where f(x) is the same as y in our slope intercept equation.
Rearranging the function, it becomes
f(x)= – 5x +4
The intercept is 4
Option C is the correct answer.
Answer: The original price of washing machine is $250.
Step-by-step explanation:
Since we have given that
Rate of decline in normal prices = 17%
Amount of normal price reduced by = $42.50
Let the original price be x
According to question,
Hence, The original price of washing machine is $250.
