What is the slope of a line perpendicular to the line whose equation is x+y=5x+y=5. Fully simplify your answer.

Answers

Answer:

1

Step-by-step explanation:

x+y = 5

Put this equation in slope intercept form y = mx+b where m is the slope

y = -x +5

The slope of the line is -1

Perpendicular lines have slopes that multiply to -1

-1 * m = -1

m = 1

The slope of the perpendicular line is 1

Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $29 monthly fee and charges an additional $0.13 for each minute of calls. The second plan has an $11 monthly fee and charges an additional $0.17 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?

Answers

Answer:
With 250 minutes of calls the cost of the two plans is the same

Step-by-step explanation:
We must write an equation to represent the cost of each call plan.
For the first plan
Monthly fee
$ 13
Cost per minute
$ 0.17
If we call x the number of call minutes then the equation representing the cost c for this plan is:

For the second plan
monthly fee
$ 23
Cost per minute
$ 0.13
If we call x the number of call minutes then the equation representing the cost c for this plan is:

To know when the cost of both plans are equal, we equate the two equations and solve for x.



With 250 minutes of calls the cost of the two plans is the same: $55.5

Rounding 55,183 to the nearest thousand gives

Answers

Answer:

55,000

55,183 is closer to 55,000 than to 56,000

To round to the nearest thousand look at the hundreds number, if the number is below 5 then the thousands number remains the same and the digits less than the thousands become zeros, if the hundreds number is 5 or higher you add 1 to the thousands number and the digits less than the thousands become zeros.

The hundreds number is 1, so the thousands number remains 5.

What are the coordinates of the point on the directed line segment from (−4,10) to (-2, -2) that partitions the segment into a ratio of 3 to 1? HURRYYYY!!!!

Answers

Answer:

(-2.5 , 1)

Step-by-step explanation:

the x- coordinates :

[(3×(-2)) + (1×(-4))] /(3+1)

= (-6 +(-4))/(4)

= -10/4

= -2.5

the y-coordinates :

[(3×(-2)) + (1×10)] / (3+1)

= (-6+10)/(4)

= 4/4

= 1

so, the coordinates are (-2.5 , 1)

Answer:

(-2.5, 1)

Step-by-step explanation:

Directed line segment from (−4,10) to (-2, -2).

The ratio = 3/1.

The coordinates are:

x = -4 + 3/4*(-2 - (-4)) = -4 + 3/4*(2) = -4  + 1.5 = - 2.5y = 10 + 3/4(-2 - 10) = 10 + 3/4*(-12) = 10 - 9 = 1

Enter and solve an equation to find the measure x of the congruent angles.

An equation is_______ = 180.

The congruent angles each measure _______°.

Answers

Answer:

if i am rightthe two other angles arre 39

Step-by-step explanation:

if a triganle is 180 degrees and you have already one angle then all you do is subtract 180 and 102

180-102= 78

then since you need the other two angles all you do is divide it by 2

so 78/2= 39 so the two missing anlges are 39
