Answer:

I think B sorry if wrong

Answer:

It is b

Step-by-step explanation:

Like I said in the previous answer the direction of the "<" sign can tell you, and since it is the " < or equal to " sign it is a solid line not dotted. So therefore its b.

Answer:

0.42*8 =3.2

Answer: = 4y + 7z + 8

Answer:

7z+4y+8

Step-by-step explanation:

Collect the like terms so 12z-5z would be 7z, then since there is only 1 y term it would be 4y, and -7 + 15= 8

Answer:

a₁ = - 148

Step-by-step explanation:

The n th term of an AP is

[tex]a_{n[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given d = 2 and a₃₁ = - 88 , then

a₁ + (30 × 2) = - 88

a₁ + 60 = - 88 ( subtract 60 from both sides )

a₁ = - 148

a₁ = - 148

Step-by-step explanation:

The n th term of an AP is

= a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given d = 2 and a₃₁ = - 88 , then

a₁ + (30 × 2) = - 88

a₁ + 60 = - 88 ( subtract 60 from both sides )

a₁ = - 148

Answer:

Y=13

Step-by-step explanation:

X is 45 so

45+5y+5=9y-2 solve and y=13

Answer:

y = 13

Step-by-step explanation:

x  + 135 = 180                   {linear pair}

         x = 180 - 135

          x = 45

 9y - 2 = 5y + 5 + x    {Exterior angle property of triangle}

 9y - 2 = 5y + 5 + 45

9y - 2 = 5y + 50       {Subtract 5y from both sides}

9y -5y  -2 = 50

  4y - 2 = 50              {Add 2 to both sides}

         4y = 50 + 2

         4y = 52             {Divide both sides by 4}

            y = 52/4

      y = 13

Answer:

x = - 3

Step-by-step explanation:

Given

3(x - 6) + 6 = 5x - 6 ← distribute and simplify left side

3x - 18 + 6 = 5x - 6

3x - 12 = 5x - 6 ( subtract 5x from both sides )

- 2x - 12 = - 6 ( add 12 to both sides )

- 2x = 6 ( divide both sides by - 2 )

x = - 3

Step-by-step explanation:

Here 42% of annual health premium($5450)=*5450

                                                                     =$2289

This amount is being paid by the company means it is deducted amount in one year.

One year has 26 paychecks so above amount divided by 26 is rebate amount in each paycheck.

Deducted amount=

Answer:

The equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x + \frac {-13}{5}[/tex].

The equation of the line perpendicular to the given line is

[tex]y=-5 x -13[/tex].

Step-by-step explanation:

The given line is y=-5x+6

The slope of the given line, [tex]m_1=-5[/tex]

Let [tex]y= m_2 x + C_2[/tex] be the slope of the line perpendicular to y=-5x+6,

where [tex]C_2[/tex] is constant.

As multiplication of slopes of two perpendicular lines equal to -1, so

[tex]m_1m_2=-1 \\\\\Rightarrow -5\times m_2= -1 \\\\\Rightarrow m_2= \frac {-1}{-5}= \frac 1 5[/tex]

So, the equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x +C_2[/tex] which passes through the point (-2,-3), so

[tex]-3=\frac 1 5 (-2) +C_2 \\\\\Rightarrow C_2 = -3 +\frac 2 5= \frac {-13}{5}[/tex]

Hence, the equation of the line perpendicular to the given line is

[tex]y=\frac 1 5 x + \frac {-13}{5}[/tex].

Now, let [tex]y=m_3 x +C_3[/tex] be the equation of the parallel line to y=-5x+6.

As the slopes of two parallel lines are the same, so [tex]m_3=-5[/tex].

So, the equation of the parallel line becomes

[tex]y=-5 x +C_3[/tex] which passes through the point (-2,-3), so

[tex]-3=-5 (-2) +C_3 \\\\\Rightarrow C_2 = -3 - 10 = -13[/tex]

Hence, the equation of the line perpendicular to the given line is

[tex]y=-5 x -13[/tex].

We use inverse cosine to find the angle

arccos(8/20) = 66.4 deg

Answer:

Each base angle of one triangle is 54°

Step-by-step explanation:

Since the angles meeting in the center are congruent and all form 360° then it means each angle will be 360°/5 = 72°(since we have 5 angles).

Since they are all isosceles triangles, it means two base angles are equal and can be gotten by:

(180 – 72)/2 = 54°.

Each base angle of one triangle is 54°

The measure of a base angle of one of the triangles is 54°.

Given that,

A regular pentagon is created using the bases of five congruent isosceles triangles, joined at a common vertex.

A regular pentagon is shown. Lines are drawn from each point to a point in the center to form congruent isosceles triangles.

The lengths of all lines are congruent. The total number of degrees of all center angles is 360 degrees.

The total number of degrees in the center is 360°. If all five vertex angles meeting at the center are congruent,

We have to determine,

What is the measure of the base angle of one of the triangles?

According to the question,

The lengths of all lines are congruent. The total number of degrees of all center angles is 360 degrees.

The total number of degrees in the center is 360°. If all five vertex angles meeting at the center are congruent,

The angles meeting in the center are congruent and all form 360°.

then it means each angle will be,

[tex]=\dfrac{360}{5}\\\\= 72 \ degree[/tex]

There are 5 angles.

Therefore,

All isosceles triangles, it means two base angles are equal and can be,

[tex]=\dfrac{180-72}{2}\\\\=\dfrac{108}{2}\\\\=54[/tex]

Hence, Each base angle of one triangle is 54°

Answer:

Step-by-step explanation:

Lands on C on 8 out of 30 times = 4/15= .26666 times

we expected to land on C using theoretical probability 1/5 =.2 times

for 1,000 times it will be expect to land on C, 200 times because,

1*200 = 200 C  : 5*200 =1,000 spins

we do not expected to land on C exactly 200 times yet we expected  something close to that 200 number.

Answer:

IQR= (16)−(10)=6

Thus, option 'C' is true.

Step-by-step explanation:

Given the data

8, 9, 9, 10, 12, 12, 13, 14, 15, 15, 15, 16, 18, 19, 20

The interquartile range is equal to the difference between the 75th and the 25th percentiles

The 25th percentile is 10

The 75th percentile is 16

Finally,

IQR= (16)−(10)=6

Thus, option 'C' is true.

Answer:

there is one solution

Step-by-step explanation:

Answer:

a. y = 3

b. x = 1

c. y-intercept = 5

d. x-intercept = -2.5

e. 2

f. y = 2x + 5

Step-by-step explanation:

Based on the graph, we can see the point where x is -1, y = 3.

Based on the graph, we can see the point where y = 7, x = 1.

Based on the graph, we can see the y-intercept is 5.

Based on the graph, we can see the x-intercept is -2.5.

To calculate the slope of the line, I will be using the points (-1, 3) and (0, 5).

Slope = [tex]\frac{rise}{run}[/tex]

           = [tex]\frac{5-3}{0-(-1)}[/tex]

           = [tex]\frac{2}{1}[/tex]

           = 2

The equation of a line is: y = mx + c where m is the slope and c is the y-intercept. Thus, the equation of the line in this case is: y = 2x + 5
