Susan is choosing tween two cell phone plans that offer the same amount of free minutes.
Plan A charges $29.99 per month with additional minutes costing $0.45
per minute.
Plan B charghes $39.99 a month with addtional minutes costing $0.40 per minute. If the equation for Plan A is
0.45x + 29.99 and the equation for plan E
is 0.40x+ 39.99, then how many addtional minutes, x, will it take for the two plans to cost the same?

Answers

Answer:

200

Step-by-step explanation:

You can simply just graph it and see where the points intersect, or you can do it algebraically.

0.45x+29.99=0.40x+39.99 subtract 29.99 both sides

0.45x=0.40x+10.00 subtract .40x both sides

0.05x=10.00 divide both sides by 0.05

Line segment XY has endpoints X(5,7) and Y(-3,3)

Answers

y=-2x+7

Step-by-step explanation:

line segment xy has endpoints x(5 7) and y(-3 3)

for the equation of the perpendicular bisector of line segment xy

slope of line segment xy = 7-3 / 5+3

= 4/8

=1/2

so slope of perpendicular bisector is -2

as m1m2= -1 or m1= -1/m2

As perpendicular bisector goes through midpoint of xy , let's find midpoint of xy

midpoint(x,y) = (5-3 / 2 , 7+3 / 2)

=(2/2, 10/2)

=(1,5)

find the equation of line(perpendicular bisector) passing through (1,5) and the slope -2

y-5 = -2(x-1)

y-5 =-2x+2

y=-2x+7

Answers

Answer:

m∠1 = 52, m∠2 = 60

Step-by-step explanation:

68 and ∠2 are interior angles. 128 is exterior angle.

Formula : -

Sum of two interior angles = Exterior angle

68 + ∠2 = 128

∠2 = 128 - 68

∠2 = 60

∠1 and 128 are linear pair angles. Sum of linear pair angles is 180,

∠1 + 128 = 180

∠1 = 180 - 128

∠1 = 52

please help me

Answers

Answer:

(D)

Step-by-step explanation:

Becuase 81 is greater than 9 and 9 is less than 12 (I hope this helps) :)

Step-by-step explanation:

12 less ( subtracting 12 from something else)

the quotient-Dividing between two values

A number: let's use Y

so we want to substract 12 from the product of y/9

(Y/9) -12.

So 81 is greater than 9 but 9 is less than 12.

Answers

Answer:

C.  Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)

f(x)=2+|x-3| for all x than the value of the derivative of x=3 is

Answers

The derivative at x = 3 does not exist.

To see why, recall the definition of absolute value:

[tex]|x| = \begin{cases}x&\text{if }x\ge0\\-x&\text{if }x<0\end{cases}[/tex]

If x - 3 ≥ 0, then

2 + |x - 3| = 2 + (x - 3) = x - 1

and the derivative of this piece is 1 for all x > 3.

If x - 3 < 0, then

2 + |x - 3| = 2 - (x - 3) = 5 - x

and its derivative is -1 for all x < 3.

The derivatives to either side of x = 3 are not the same, so f '(x) is not continuous and indeed does not take on any value at this point.
