By solving a linear equation, we can see that the measures of the segments are:

Here we have 3 collinear points, a, b, and c.

We know that the measures are:

ab = 9

ac = x + 19

bc = 2x + 18

If b is between a and c, then we should have that:

ac = ab + bc

Replacing the measures we get:

x + 19 = 9 + (2x + 18)

Now we can solve this linear equation to find the value of x.

x + 19 = 9 + 2x + 18

x + 19 = 27 + 2x

19 - 27 = 2x  -x

-8 = x

Then the measures are:

ab = 9

ac = -8 + 19 = 11

bc = 2*(-8) + 18 = -16 + 18 = 2

Domain: 1 < x < 5

Range: -10 < y < 2

Step-by-step explanation

First, we need to graph the function. The function is just a linear function, but arranged differently. You can rearrange it to be:

[tex]f(x) = -3x + 5[/tex]

Now graph the function. The slope of it should be -3, and the y-intercept is 5.

To find the domain, just use the relation of the x values given with the function (1 < x < 5).

To find the range, plug the smallest and largest values of the domain into the function given. 1 and 5 should be the numbers you are plugging in. The outputs will be the range. Remember that negative numbers are smaller than positive numbers, so the negative number should be on the left.

Find an inequality that represents the possible landing or takeoff conditions of an aircraft.

The necessary inequality is denoted by the symbol.

-40<x<118

The temperature range in which the aircraft is possible to take off or land is shown by the graph.

Due of the high temperatures in Phoenix, Arizona in June of 1990, the pilot could not have safely taken off.

Let us represent the temperature with the symbol x

Therefore, the temperature must be above or equal to.

-40F so x>-40

Therefore, the temperature can't be at or higher than.

118F so x<118

The disparity between them will be.

-40<x<118

It is possible to observe from the graph that the area colored in gray encompasses all of the points that lie between -40 and 118, but it will not include the points -40 and 118.

The temperature range in which the aircraft is possible to take off or land is shown by the graph.

x = 74 degrees is the angle

Let x = the angle

then

(180-x) is the supplement of x

and

(90-x) is the complement of x:

"The supplement of an angle is 26 more than 5 times its complement."

(180-x) = 26 + 5(90-x)

180 - x = 26 + 450 - 5x

-x + 5x = 26 + 450 - 180

4x = 296

x = [tex]\frac{296}{4}[/tex]

x = 74 degrees is the angle

5 times its complement.

(180-74) = 26 + 5(90-74)

106 = 26 + 5*(16)

106 = 26 + 80; confirms our solution

In  elementary geometry , an angle  is that the  figure formed by two rays, called  the edges  of the angle, sharing  a standard  endpoint, called the vertex of the angle. Angles formed by two rays  dwell  the plane that contains the rays. Angles also are  formed by the intersection of two planes. These are called dihedral angles. Two intersecting curves  can also  define an angle, which  is that the  angle of the rays lying tangent to the respective curves at their point of intersection.

Angle is additionally  used to designate the measure of an angle or of a rotation. This measure  is that the  ratio of the length of a circular arc to its radius.  within the  case of a geometric angle, the arc is centered at the vertex and delimited by  the edges .  within the  case of a rotation, the arc is centered at  the middle  of the rotation and delimited by any other point and its image by the rotation.

Potentially, an angle denoted as, say, ∠BAC, might  ask  any of four angles: the clockwise angle from B to C, the anticlockwise angle from B to C, the clockwise angle from C to B, or the anticlockwise angle from C to B, where the direction  during which  the angle is measured determines its sign (see Positive and negative angles).

Answer:

a. -11, 97, 6, 87

b. he didn't get over it

Step-by-step explanation:

a. The table shows you the grade in the upper row and in the lower row difference between upper row and 90. So to calculate lower row you need to do X-90 where X is upper row value. To calculate upper row you need to do X+90 where X is lower row value

so you get column 3:

79-90=-11

column 4:

90+7=97

column 5:

96-90=6

column 6:

-3+90=90-3=87

b. To answer this question we would need to simply sum all the values from the Above/Below row for all 6 columns:

-7+4+(-11)+7+6+(-3)= -7+4-11+7+6-3=-4. Since the value is negative it means it's below 90

The probability of selecting a 5 and the coin landing on head is 1/26

In this question, a card is drawn at random from a standard pack of playing cards and fair coin is flipped.

Here, we have two different sample spaces to work with and we want to calculate a compound probability.

Firstly in a deck of cards which contain a total of 52 cards, there are 4 cards labeled 5.

So, the probability of selecting a 5 is:

4/52 = 1/13

Also, in a flip of coin the probability of the coin landing on head is 1/2

Thus the probability of selecting a 5 and the coin landing on head would be,

probability of selecting 5 × probability of the coins landing on head

= 1/13 × 1/2

= 1/26

Step-by-step explanation:

Work for 30 hours in a week $10 per hour

The domain and the range for the given situation will be:

Domain = [0, 30]

Range = [0, 300]

Given that Josie earns $10 per hour at her job. Her hours vary, but she never works more than 30 hours in any given week,

We need to find the domain and range.

In this situation, the domain refers to the possible values for the input variable, which is the number of hours Josie works in a given week.

The range, on the other hand, refers to the possible values for the output variable, which is her earnings for the week.

For the domain:

Since Josie never works more than 30 hours in any given week, a reasonable domain for this function would be from 0 to 30 hours. We don't consider negative hours (as it doesn't make sense in this context), and the upper limit is set by her maximum weekly working hours.

Domain = [0, 30]

For the range:

The range should be the possible earnings Josie can make in a week based on her hourly rate of $10 per hour.

To find the range, we multiply her hourly rate by the maximum number of hours she can work in a week, which is 30 hours.

Range = [0, 10 x 30] = [0, 300]

So, the function that represents Josie's possible earnings for one week is:

Earnings = f(hours) = 10 x hours

Where "hours" is the number of hours she works in a week, and "Earnings" is the corresponding amount she earns.

The graph of this function will be a straight line passing through the origin (0, 0) and with a slope of 10, representing her earnings increasing linearly with the number of hours worked.

The line will extend up to the point (30, 300) and then flatten out as she cannot earn more than $300 in a week.

Step-by-step explanation:

Given that,

Hence, option (b) is correct.

The change in temperature from morning to night is ₋18°F which means the temperature decreased from morning to night.

Given the temperature in the morning is ₋10°F

and temperature in the night is 8°F

To calculate the difference, subtraction is used between the starting and final temperatures. In other words, if something starts at 50 degrees Celsius and ends up at 75 degrees C, the temperature difference is 25 degrees C, or 75 degrees C minus 50 degrees C. The outcome is adverse for drops in temperature.

change in temperature from morning to night  = ₋10°F ₋ 8°F

= ₋18°F

the result is negative, hence the temperature decreases from morning to night.

Hence we get the temperature change as ₋18°F.
