Answer:
#1 is 2x-12°=-12
#2 is x+34°=34
Step-by-step explanation:
when it tells you to add the second number will always be that number but a positive.
when it tells you to subtract the second number will always be that number but a negative.
plus=positive
minus=negative
remember that.
hope that helped you out!
<span>The median is a better measure of center when there is an outlier which will make the mean not be a good estimate of the center. Option B has $1075 as an outlier (i.e. it is far away from the other data sets). Hence, the median will be a better estimate of the center. Similarly, 94 is an outlier in option C and hence, the median is a better estimate. Options A and D has no outliers, making the mean a good estimate of the centre.</span>
Answer:
- vertex: (-5/8, 7/16)
- axis of symmetry: x = -5/8
Step-by-step explanation:
For quadratic ax²+bx+c, the axis of symmetry is located at x=-b/(2a).
Here, we have a=4, b=5, so the axis of symmetry is ...
... x = -5/(2·4) = -5/8
_____
The vertex y-value will be f(-5/8).
... f(-5/8) = (4·(-5/8) +5)·(-5/8) +2 = (5/2)·(-5/8) +2 = -25/16 +32/16
... f(-5/8) = 7/16
_____
The axis of symmetry is x = -5/8; the vertex is (-5/8, 7/16).
The answer is A. add $0.30 to $1.99 four times and it comes out to $3.19. by adding .50, the total after four years comes to $3.99. add .80 four times, $5.19. add $1.10 four times and it comes to $6.39. you can also multiply the answer choices by 4 and then add $1.99 to get the same thing.
