Answer:
d=62
Step-by-step explanation:
180-56=124
2d=124
Divide both sides by 2
d=62
Answer:
x = - 6
Step-by-step explanation:
The x-intercept is when y =0, you are looking for a point (x, 0)
So you replace y = 0 in the equation
4x - 3y = - 24
4x - 3(0) = - 24
4x = - 24
x = - 6
Answer:
(3x -1) (3x+1)
Step-by-step explanation:
9x^2 - 1
Rewriting
(3x)^2 -1^2
This is the difference of squares a^2 -b^2 = (a+b) (a-b)
(3x -1) (3x+1)
Answer:
the answer is 2.883
Step-by-step explanation:
Because when you add 0.523+2.36, the decimal points line up together. Which make it 2.883. The student's mistake was that they didn't line the decimal points together.
50mph
Step-by-step explanation:
The image of the motion of Paul's derive is attached already.
From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.
What is average speed?
Average speed is the rate of change of total distance covered with time taken .
Average speed = 
To find the total distance covered;
Distance at time 1 = 75miles
Distance at time 4 = 225miles
Distance covered between 1 - 4 = 225 - 75 = 150miles
Time taken for the journey = 4 - 1 = 3hrs
Input the values in the equation;
Average speed =
= 50mph
