40 miles in 30 minutes, 60 miles in 45 minutes
divide 80 by 60 (mins in a hour) then multiply that’s by the number of minutes (30,45)
A triangle has 180 degrees. You can find the total sum of the ratio by adding its parts together 1+3+5 = 9 Now to find out what each part of the ratio is worth we divide the whole value (180) by the sum of the ratio parts (9)
180/9 = 20
Now we multiply each part of the ratio by 20
1 * 20 = 20
3 * 20 = 60
5 * 20 = 100
Since we have an angle greater than 90 degrees this is an obtuse triangle.
Transformation involves changing the form of a function.
The absolute value function is
The parent function of the absolute value function is:

When the function is translated 2 units to the right, the new function is:

From the function to be wider than the absolute function, the function must be stretched by a factor less than 1.
The possible function from the list of given options is

1. Multiply each equation so they end up with the same coefficient
2. Subtract your second equation from the first
3. Solve for one of the variables (I tend to solve an equation that only contains 2 variables if possible. So it would be if you have one question with x and y, solve for the easier one)
4. Substitute the variable you found in the least step into one of the other equations and find a second variable.
5. Substitute both variables you found into the last equation and there you should be left with x, y, and z :))
I hope this helped sksjsk if it didn’t I could write it out to hopefully help more :)
