Answer:
Step-by-step explanation:
f(x) = x + 2.....change f(x) to y
y = x + 2....now switch x and y and solve for y
x = y + 2
x - 2 = y....change y to f-1(x)...represents an inverse
f-1(x) = x - 2 <== ur inverse
Answer:
Question 1: 4/5 or %80
Question 2: 7/10 or %70
Step-by-step explanation:
<u>Step 1: Find the total amount of marbles</u>
5 + 2 + 3
<em>10</em>
<em />
<u>Step 2: Find the probability of not drawing a black marble</u>
Add the total amount of marbles that are not black
5 + 3
<em>8</em>
<em />
Now find the probability:
8/10
4/5 or %80
Answer: 4/5 or %80
<u>Step 3: Find the probability of not drawing a red marble</u>
Add the total amount of marbles that are not red
5 + 2
<em>7</em>
<em />
Now find the probability:
7/10 or %70
Answer: 7/10 or %70
Answer:
<h2>
X-intercept: (2, 0)
</h2><h2>
Y-intercept: (0, 6)
</h2>
Step-by-step explanation:
X-intercept means y-coordinate of 0:
6x +2×0 = 12
6x = 12
x = 2 ← x-coordinate
Y-intercept means x-coordinate of 0:
6×0 + 2y = 12
2y = 12
y = 6 ← y-coordinate
Answer:
<u><em>Club #7: M= 1/8 Club #8: M= -7/6</em></u>
Step-by-step explanation:
Explanation: M=Slope which also equals rise/run. You always look at the number that is directly in front of the x. Ex: y = 3x + 4. (<em>M=3)</em>

Step-by-step explanation:
Given
The attached piece wise function
Required
The domain
To do this, we simply consider the inequalities that bound the values of x.
The inequalities are:
and 
Combine the first two inequalities:
and
For the inequality to be true, we must have:
In interval notation, the inequality is:
