Solve. −1 − 10x < −1

Answers

Answer 1

The solution to the inequality is x > 0

What is Inequality?

Inequality in mathematics differentiate two values,  if one is less than, greater than, or not equal to another value

Evaluate the equation by letting the unknow to be on one side

−1 − 10x < −1

-10x < -1+1

Add +1 to both sides

= -1-10x+1 < -1+1

= -10x < 0

Divide both sides by -10 same factor and flip the relation because  of negative factor

=  -10x /-10 > 0/-10

= x > 0

Therefore the solution to the inequality is x>0

f(-3) evaluate the function of the graph

Answers

The composition f(-3) has a value of 1

How to evaluate the function on the graph?

The definition of the function is represented by the graph

So, we call the graph function f(x)

To find the function f(-3), we set the value of x in the function of the graph f(x) to -3

This is represented by

Calculate f(x), when x = -3

So, we look for the corresponsing points on the graph where x = -3

In this case;

The value of the function is 1 when the value of x is -3

This means that

answer:

x = 18, 60.

step-by-step explanation:

evaulating (3x+6) = (4x-12) and solving for x gives us x = 18. you didn't include the angle, so i can't give you that. but

(3x+6) = 60

(4x-12) = 60

if those were your angles, you would have an equilalateral triangle (all sides/angles even) and your missing angle would also be 60.

Step-by-step explanation:

The answer is given in the graph I've made for you. The distance you want is a contained in a line that is perpendicular to the given line and goes through (2,-1). If I have not interpreted this correctly please leave a comment under the question and I will edit it. I have ignored the 4.

The steps needed are

Find the slope of the line perpendicular to y = - x + 4Find the intersection point on y = - x + 4 and the new line.Use the distance formula to find the distance from (2,-1) to the intersection point found in the second step

Givens

line y = -x + 4

point (2,-1)

Solution

The slope of the second line is

m1 * m2 = - 1

m1=  -1                From the given equation

m2 = ?

-1 * m2 = - 1

m2 = 1

Find the equation of the new line

x = 2

y = - 1 from the given point

-1 = 2 + b             Subtract 2 from both sides

-1 - 2 = 2-2 + b    Combine

-3 = b

Equation of the new line

y = x - 3

Intersection point of the two lines

y = -x + 4

y = x - 3              Add The xs cancel

2y = 1                  Divide by 2

y = 1/2

1/2 = -x + 4          Subtract 4 from both sides

1/2 - 4 = -x + 4 -4 Combine        

-3 1/2  = -x            Multiply both sides by - 1

3 1/2 = x

So the intersection point is (3.5, 0.5)

Find the distance between (2,-1) and (3.5,0.5)

d = sqrt( (2 - 3.5)^2 + (-1 - 0.5)^2 )

d = sqrt( (-1.5)^2 + (-1.5)^2 )

In the function f(2)= -5, 2 is the preimage of the function and 5 is an image of the function.

What is a function?

A unique kind of relation called a function is one in which each input has precisely one output. In other words, the function produces exactly one value for each input value. The graphic above shows a relation rather than a function because one is mapped to two different values. The relation above would turn into a function, though, if one were instead mapped to a single value. Additionally, output values can be equal to input values.

The x-values are input into the function machine. The function machine then performs its operations and outputs the y-values. The function within can be any function.

Suppose that f(a) = b

In that case, element "b" is the image of element "under the function," while element "a" is the preimage of element "under the function."

In the given function f(2)= -5

2 is the preimage of the function and 5 is an image of the function.

Hence, the 2 is the preimage of the function and 5 is an image of the function.

What is meant by probability?

Probability is a branch of mathematics that deals with numerical descriptions of how likely an event or statement is to occur. An event's probability is a number between 0 and 1, where 0 indicates impossibility and 1 represents certainty. The more likely an occurrence is, the more likely it will occur. A simple example is tossing a fair (unbiased) coin. Because the coin is fair, all outcomes are equally likely; the probability of "heads" equals the probability of "tails," and because no other outcomes are possible, the probability of "heads" or "tails" is 1/2.

Given,

Age       Users     Pop-music

subtract 60 to both sides:

-8x - 60 + 60 ≤ 10 + 60

how many three-digit positive integers leave a remainder of 2 when divided by 5 and a remainder of 6 when divided by 7?

Answers

There are 180 three-digit numbers that leave a remainder of 2 when divided by 5 and 128 three-digit numbers that leave a remainder of 6 when divided by 7.

The smallest 3-digit number to leave a remainder of 2 when divided by 5 is 102.

The next number will be 107, and then 112,

The last 3 digit number to leave a remainder 2 when divided by 5 is 997

Therefore here we get an Arithmetic Progression

102, 107, 112, ..., 997

We know that for any term of an A.P

aₙ = a + (n - 1)d

where,

a = first term

n = the order number of that particular value

d = common difference

Here,

a = 102

d = 107 - 102

= 5

The number of 3 digit number for the above problem will be the value of n for 997

Hence we get

997 = 102 + (n - 1)5

or, 102 + 5n - 5 = 997

or, 5n + 97 = 997

or, 5n = 997 - 97

or, 5n = 900

or, n = 900/5

or, n = 180

Next, we need to find the no. of three-digit numbers that leave the remainder of 6 when divided by 7

The smallest 3-digit number to leave the remainder of 6 when divided by 7 is 104

The largest is 993

Therefore, just like before, we get the A.P

104, 111, 118, ..., 993

here,

a = 104

d = 7

aₙ = 993

Hence we get,

993 = 104 + (n - 1)7

or, 104 + 7n - 7 = 993

or, 97 + 7n = 993

or, 7n = 993 - 97

or, 7n = 896

or, n = 128

a person's blood glucose level and diabetes are closely related, let x be a measurement in milligrams of glucose per deciliter of blood, after 12-hour fast, the variable x will have a Distribution that is approximately normal with a mean of 85 and standard deviation of 25. this is only true for adults under 50. Use this information to answer the question that follow:

what percentage of people have a blood glucose level between 100 and 125?

Answers

The percentage of people that have a blood glucose level between 100 and 125 is 21.945%

How to determine the percentage between 100 and 125?

From the question, the given parameters about the distribution are

Mean value of the set of data = 85

Standard deviation value of the set of data = 25

The actual data values = 100 and 125

The z-score of the data value is calculated using the following formula

z = (x - mean value)/standard deviation

For x = 100, we have:

Substitute the given parameters in the above equation

z = (100 - 85)/25 = 0.6

For x = 125, we have:

Substitute the given parameters in the above equation

z = (125 - 85)/25 = 1.6

The percentage between 100 and 125 is then calculated as:

P(100 < x < 125) = P(z < 1.6) - P(z < 0.6)

From the z table of probabilities, we have;

P(100 < x < 125) = 0.9452 - 0.72575

This gives

P(100 < x < 125) = 0.21945

Express as percentage

P(100 < x < 125) = 21.945%

Hence, the percentage is 21.945%
