Answer:
We know that that x represents (1)
2/5 is the answer because if you add, multiply them together you will get 2/5=40/100%
Hope this helps

Answer:
A
Step-by-step explanation:
A piece wise function involves two or more functions over specific intervals. The equations of the two lines are the following y=-2x+1 and y=-x+2. The line y=-x+2 continues to the right but has an open circle at the end so this point is not included. This means the interval is a greater than than sign but is not equal to. A is the answer.
Answer:
In slope intercept form:
y= .2x -1
Step-by-step explanation:
You can find the slope by using the formula (y2-y1)/(x2-x1).
Then you get: (-2-2)/(-5-15) = -4/-20 = .2
.2 is your slope(m).
Plug this information into point slope form: y-y1 = m(x-x1)
y-2 = .2(x - 15)
Distribute the .2.
y-2 = .2x - 3
Rearrange the formula to isolate y.
y = .2x -1
Answer: 1a. f(2) is an x-value
1b. f(x) = 4 is a y-value
1c. f(-10) is an x-value
1d. m(x) = 64 is a y-value
2. f(4) = 17
3. x = 39
Step-by-step explanation: In general, if there is an equal sign, the output f(x) is a y-value. if the expression is f(#) with a number in the parentheses, that is the value to insert for x.
2.) f(x) = 2x + 9
f(4) = 2(4) + 9
f(4) = 8 + 9
f(4) = 17
3. f(x) = 5x -3
192 = 5x -3
192 + 3 = 5x
195 = 5x
39 = x
