24a-18a+12a is equal to 18a
hence, divide it by 6a
so you get 3a :)
Yes because if you add forty and thirty that equals seventy plus twenty is 90 which is a right angle
Answer:
The slope-intercept form is 
Step-by-step explanation:
To find the slope, use
Replace the x and y values with the points.
Solve.
After that, find the y-intercept form.
Put the equation in point-slope form.
Replace x with 0.
Add 5 to both sides.
Convert to improper fraction form.
The y-intercept is 
Now finally, write in slope-intercept form. (y=mx+b)
m is slope, b is the y-intercept.
D=56t because if t is hrs then u would multiply 56 and t to find the miles per hour
The correlation coefficient of the data provided is -0.52.
<h3>What is the correlation coefficient?</h3>
Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.
Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.
Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52
