(h,k) is the vertex
b/2a is the line of symmetry
a > 0 parabola opens upward, vertex is a minimum
a < 0 parabola opens downward, vertex is a maximum

Answer:
x=27
Step-by-step explanation:
i would give you the steps but honestly, im tired of giving 20 steps for every problem i answer.
A. y-intercept
B. The slope is 3/4, the y-intercept is 0
C. For this one you need to put it in y-intercept form. So, you subtract 2x, and move it over to 12. The equation would look like 6y = 2x + 12.
Then, divide everything by 6, and the equation would look like: y = 2/6x + 2
Thus, the slope is 2/6x and 2 is the y-intercept.
Answer:
C; A singleton set
Step-by-step explanation:
Mathematically, when a number is non-negative; it is either positive or zero
Now, this is because 0 identifies as neither a positive or a negative number
hence, when we find the difference between the two sets, the only number that stands out unmatched is the value 0
What this mean is that we are having a set with a single number result
So we have our answer as {0}
Which is a singleton set
X= assistant's wage
x+15= instructor's wage
Add their wages set equal to $65
x + (x + 15)= 65
combine like terms
2x + 15= 65
subtract 15 from both sides
2x= 50
divide both sides by 2
x= $25 assistant's wage
x+15= 25 + 15= $40 instructor's wage
ANSWER: (C) $25 hourly wage of assistant
Hope this helps! :)
