Answer:
transformations of function 3(-7(x+2))-4
- vertical stretch
- horizontal compression
- translates left
- translates down
- reflection across y-axis
Check picture below, solve for "x" and "y"
unless you've already covered the 30-60-90 triangle, then check your book on them, to see the ratios, using the 30-60-90 ratios is simpler
Answer: C 75
Step-by-step explanation: time to distance is ratio 4:5 = 60:X
In 1min He walks 5/4
in 60mins He walks 5/4 ×60
B is the Y-intercept or where the graph crosses the y-axis. they provide you with a few things which can help you figure this out. they give you the values of x and y in a table
X | Y
2 | -5
4 | -9 The difference between each Y value is 4...so, I add 4 to the -5
6 | -13 and get -1...going up another value for the X would be at 0. This leaves me with an ordered pair of (0,-1).....thus, the value of b is -1.
Unit rate is when a rate is simplified so it has a denominator of 1 (x = 1) and y≠ 0
unit rate = y/x
Answer: Point C <span>represents the unit rate</span>
