Y-3 = -2(x+5)
Rewrite in slope intercept form:
y-3 = -2(x+5)
Simplify the right side:
y-3 = -2x -10
Add 3 to both sides:
y = -2x -7
The y intercept is -7
1/64
1/root3 64
1/4
You first deal with the negative and put the 64 below
Then you find the cube root of 64 which equals 4
If he saves $6 from every $15 he gets, then getting $75 means he saves $30.
Lets says he is paid 15 dollars every hour, and from those he saved 6 dollars. If he earned 72 dollars, that means he is paid 5 times (because 75/15 is 5). So if every time he is paid he saves $6, being paid 5 times means he saves $30 ($6 *5).
