Answer:

x =  -14.75

Step-by-step explanation:

-4(5+x)=39         (Distribute)

-20 - 4x = 39          (Add 20 on both sides)

-4x = 39 + 20

-4x = 59             (Divide by -4)

x = -14.75

Answer:

First think of what you are trying to solve.

What is X?

Reverse the steps in solving:

[tex]39 / -4 = -9.75[/tex]

Now after doing that, subtract it by 5:

[tex]-9.75 - 5 = -14.75[/tex]

Now after doing that, to check your work:

[tex]-14.75 + 5 = -9.75 * -4 = 39[/tex]

So the answer for X is -14.75

There you go I hoped I helped :]

Answer:

Step-by-step explanation:

1. Angles P₂ and N₁ are opposite angles of inscribed quadrilateral PMNQ, so are supplementary. Angles N₁ and N₂ form a linear pair, so are supplementary. Angles supplementary to the same angle (N₁) are congruent, hence P₂ = x ≅ N₂

__

2. ΔPMQ is isosceles, so angle Q₁ is also congruent to x.

__

3. In ΔPMQ, the sum of angles is 180°, so ...

  M₁ +2x = 180°

Dividing by 2 gives ...

  M₁/2 +x = 90°

Angle M₁ subtends arc PQ of circle M. Angle R inscribed in circle M subtends the same arc, so ...

  R = (M₁/2)

  R = 90° -x

__

4. From the above, we know that angles N₂ and R are complementary (total 90°), so angle S₂ = 90°. Segment MS will only intersect chord PR at right angles at the midpoint of that chord.

Hence S is the midpoint of PR and PS = SR.

Answer:

  not on the same line

Step-by-step explanation:

Any two distinct points define a line. Additional points may or may not be on that line. If they are on the line, they are collinear with other points on the same line.

Any point not on the line is noncollinear with the points that are on the line.

Answer:

its a complementary angle, so number B

Answer:

10 years

Step-by-step explanation:

Given

Decline from (0,h) to (10,0)

See attachment for graph

Required

Determine the age when height = 0

The function of the graph is represented as: (age, height)

So, we need to read from the graph the corresponding value of age (on the x-axis) when height = 0 (i.e. the y-axis)

From the attached graph;

[tex]age = 10[/tex] when [tex]height = 0[/tex]

Hence, the age of the car is 10 years

Answer:

Part 1: plant f

Part 2: plant g

Part 3: plant g

Step-by-step explanation:

✔️First plant:

Function: f(t) = 0.5t + 2

where,

f(t) = height of plant

t = number of days

m = slope/rate of change = 0.5 cm/day

b = y-intercept/initial height = 2 cm

✔️Second Plant: using two points on the graph, (0, 5) and (16, 9), let's find b and m for the function of the second plant.

Slope/rate of change (m) = ∆y/∆x = (9 - 5)/(16 - 0) = 4/16 = 0.25

m = 0.25 cm/day

The y-intercept or initial height is the y-coordinate of the point where the line intercepts the y-axis = 5

b = 5 cm

Towbrute the equation of the function, substitute m = 0.25 and b = 5 into g(t) = mt + b

Thus:

g(t) = 0.25t + 5

Knowing these, let's answer the problem given:

Part 1: plant f was growing faster because it has a greater rate of change/slope (m) of 0.5 cm/day

Part 2: plant g was taller because it has a greater initial value/y-intercept (b) which is 5 cm

Part 3: To find out which plant was taller after 8 days, substitute t = 8 into the equation of each function:

Plant f: f(t) = 0.5t + 2

f(8) = 0.5*8 + 2 = 4 + 2

f(8) = 6 cm

Plant g: f(t) = 0.25t + 5

g(8) = 0.25*8 + 5 = 2 + 5

g(8) = 7 cm

Thus, plant g was taller after 8 days having 7 cm

Answer: The answer is 126 because if we minus 280 - 55% the answer is 126

Answer:

(1,0)

Step-by-step explanation:

Given

[tex]H = (-2,2)[/tex]

[tex]I = (4,3)[/tex]

[tex]J = (4,-2)[/tex]

[tex]K = (-2,-3)[/tex]

Required

The midpoint of the diagonals

Midpoint is calculated as:

[tex]M = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

For H and J, the midpoint is:

[tex]M = (\frac{-2+4}{2},\frac{2-2}{2})[/tex]

[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]

[tex]M = (1,0)[/tex]

For I and K, the midpoint is:

[tex]M = (\frac{4 - 2}{2},\frac{3-3}{2})[/tex]

[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]

[tex]M = (1,0)[/tex]

The midpoint of both diagonal is: (1,0)

Answer:

22

Step-by-step explanation:

10 plus 13 equals 23, so if it is more than that than the lines wont be able to connect. if it is 23 exactly, the triangle will be a stright line, not a triangle, so it is 22.

Answer:

22

Step-by-step explanation:

triangle inequality theorem:

10 + 13 > x

x < 23

10 + x > 13

x > 3

third side:  3 < x < 23

Answer:

The correct answer is:

Step-by-step explanation:

The given values are:

Service time varies,

Repair time = 2 hours

Standard deviation = 1.5 hours

Robotics uses per hour cost,

= $35

Company's cost per hour,

= $28

(a)

⇒ Arrival rate = Jobs per hours

then,

                       = [tex]\frac{8 \ hours}{3 \ jobs}[/tex]

                       = [tex]2.666 \ hours \ per \ job[/tex]

The jobs per hour will be:

⇒  [tex]\lambda=\frac{1}{2.666}[/tex]

       [tex]=0.375[/tex]

(b)

⇒ Service rate = jobs per hour

then,

                      μ = [tex]\frac{1 \ repair \ job}{2 \ hours}[/tex]

                         = [tex]0.5 \ jobs[/tex]

Answer:

The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27:1

Step By Step Explanation:

Volume of the smaller cylinder(V1)=π(r^2)h

Volume of the larger cylinder(V2)=π(r^2)h

=π(3r)^2*3h

=π*9(r^2)*3h

=27π(r^2)h

The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27π(r^2)h/π(r^2)h i.e. 27:1
