Write the equation of a line with an undefined slope that passes through the point (-6,3)

Answers

Answer:

x = -6

Step-by-step explanation:

A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.

Which value of x is a solution to this equation? 5 x 2 - 36 x + 36 = 0

Answers

5x2-36x+36=0
10-36x+36=0(multiply 5x2)
10-36x=-36(subtract 36 from both sides)
-36x=-46(subtract 10 from both sides)
x is approximately 1.28(divide both sides by -36) or 23/18

exact answer is 1.27777778

How many years will it take for $4,000 to double at a simple interest rate of 5%?​ Show your work.

Answers

Answer: in explination

Step-by-step explanation:

annual interest = .05(4000) = 200  

to double, you need another $4000  

number of years = 4000/200 = 20  

annual interest = .05(4000) = 200  

to double, you need another $4000  

number of years = 4000/200 = 20  

it will take 20 years  

to check if you are right you would...

Check:

simple interest on $4000 for 20 years at 5%  

= .05(20)(4000) = 4000  

the amount = what we had + new amount  

= 4000 + 4000 = 8000 which is double what we started with  

So the answer would be it took 20 years.

The figure below shows a shaded rectangular region inside a large rectangle:

A rectangle of length 10 units and width 5 units is shown. Inside this rectangle is a smaller rectangle of length 4 units and width 3 units placed symmetrically inside the larger rectangle. The smaller rectangle is shaded gray.

What is the probability that a point chosen inside the large rectangle is not in the shaded region?

76%
50%
24%
12%

Answers

The area of the smaller rectangle is 12, and the area of the bigger one is 50, so the probability that it is not chosen inside the shaded region is (50-12)/(50)=76%

The number x ≤ 10 for the inequality (-1/5)x + 3 ≤ 1.

What is inequality?

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

Negative one-fifth of the number, increased

by 3, is at most 1.

Number = x

This can be written as,

(-1/5)x + 3 ≤ 1

Solve for x.

(-1/5)x + 3 ≤ 1

(-1/5)x ≤ 1 - 3

(-1/5)x ≤ -2

x ≤ -2 x (-5/1)

x ≤ 10

Thus,

The number is less than or equal to 10.

If a dice is rolled 18 times, how many times is the number 2 expected to come up? *

A .2 times

B. 3 times

B. 6 times

D.9 times

Answers

Answer:

the answer is B. 3 times

that's what I think

Number of times 2 come, If a dice is rolled 18 times is 3 times. So, Option 'B' is the correct answer.

Probability based problem:

Probability of a number = Number of outcome / Total number of outcomes

Probability of getting two = 1 / 6

Number of times 2 come, If a dice is rolled 18 times = 18[Probability of getting two]

Number of times 2 come, If a dice is rolled 18 times = 18[1/6]

Number of times 2 come, If a dice is rolled 18 times = 3 times
