Which function's graph has axis of symmetry x = 2?
Ghella [55]

Answer:

y=-3x2 - 12x+6 ,     x = -(-12)/2*3 = 2  this one has axis of symmetry  x = 2

Step-by-step explanation:

y = 3x² + 12x+6  :    x = -12/6 = -2

y = 3x2 - 6x+12 ,    x = -(-6)/2*3 = -1

y=-3x2 - 12x+6 ,     x = -(-12)/2*3 = 2  this one

y=-3x2 + 12x+6 ,   x = -12/2*3 = -2

Katyanochek1 [597]

Answer:

$40 + 10x

Step-by-step explanation:

Given that:

Original cost of data plan = $40 per month for 10 GB of data

Additional data cost = $10 per GB when usage is above the original data cap

Hence, amount to be paid when usage is over the original data cap by x GB :

Original amount + (additional cost per GB * additional GB used)

$40 + ($10 * x)

$40 + 10x

What are the measures of the missing angles x°, y° of a regular triangle if one angle measure equals 60°?​
MArishka [77]

Answer:

So each interior angle measurement of the regular triangle is 60 degrees.

Step-by-step explanation:

If the triangle is regular, this means all the side measurements are congruent to each other and that all the angle measurements are congruent to each other.

If the sum of the angles in a triangle is 180 degrees and you know they are each the same then you could either solve x+x+x=180 or know we are just dealings with an equiangular triangle in which all angles have measurement 60 degrees.

If need more convincing, let's actually solve:

x+x+x=180

3x=180

x=180/3

x=60

So each interior angle measurement of the regular triangle is 60 degrees.
