Answer:
The distance would be 118
Step-by-step explanation:
The easiest way I solve the distance between a negative number and a positive number is by adding the negative (but making it a positive) and the positive together. If you add 55 and 63 you would get 118. And 118 is the distance between -55 and 63.
I hope this helps!! :)

The slope of the line shown is -2/5
Slope of a lineThe formula for calculating the slope of a line is expressed according to the formula
Slope = Rise/Run
Slope = y₂-y₁/x₂-x₁
Using the coordinate point (0,7) and (5, 5)
Slope = 5-7/5-0
Slope = -2/5

k(z) = 7z^2 + 7 , find k(8z - 2)
z(q) = -10q^2 - 5 , find z(q^2)
Answer: k(8z - 2)=448z^2-224z+35
z(q^2)=-10q^4 - 5
Step-by-step explanation:
k(z) = 7z^2 + 7
k(8z - 2)=7(8z - 2)^2 + 7
k(8z - 2)=7(8z - 2)(8z - 2) + 7
k(8z - 2)=7(64z^2-16z-16z+4) + 7
k(8z - 2)=7(64z^2-32z+4) + 7
k(8z - 2)=7(64z^2-32z+4+1) ==> 7*1=7, so +1 is added in parentheses while +7 is removed outside of parentheses.
k(8z - 2)=7(64z^2-32z+5)
k(8z - 2)=448z^2-224z+35
z(q) = -10q^2 - 5
z(q^2)=-10(q^2)^2 - 5
z(q^2)=-10(q^(2*2)) - 5
z(q^2)=-10q^4 - 5

Write the equation of the line parallel to the line and passing through
the point. Y=-2x-1, (4, 3)
Answer:
y = - 2x + 11
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x - 1 ← is in slope- intercept form
with slope m = - 2
• Parallel lines have equal slopes , then
y = - 2x + c ← is the partial equation of the parallel line
to find c substitute (4, 3 ) into the partial equation
3 = - 8 + c ⇒ c = 3 + 8 = 11
y = - 2x + 11 ← equation of parallel line

Using composition formula we get the value of x is 9/16 for G(H(X)) = 32x - 18
What is the composition formula?In mathematics, composing a function is the process by which two functions, f and g, produce a new function, h, such that h(x) = g(f(x)). This indicates that the function of g is being applied to the function of x. In essence, a function is then applied to the outcome of another function.
We F (2x-18) and G (4x)
By using the composition formula
H(x) = g(f(x))
That is
H(x) = g(2x-18)
= 2(4x) - 18
= 8x - 18
If H(x) = 8x - 18
Then, G(H(x))
⇒ G(8x - 18)
⇒ 8(4x) - 18
⇒ 32x - 18
Now, we find x in G(H(x))
⇒ 32x - 18 = 0
⇒ 32x = 18
⇒ x = 18/32
⇒ x = 9/16

Find the value of x in each case
Answer: x = 23
Step-by-step explanation:
Angle in a X shape, the two 'opposite' eachother must be the same so angle HGC is 14
Angle in a Z shape where the lines of the Z are parralell, the two innercorner angles of the Z must be the same os angle GCE must be 14
In triangle GEC we now know two out of the three angles 78 and 14 and we know that angles in a trianlge add up to 180 so the missing angle GEC must be 180-78-14=88
Angles on a straight line must add up to 180 so 4x+88=180
Then this can be used to figure out x
4x+88=180
4x = 92
x = 23
given values of median, mean, mode, first and third quartiles for the observations of a numeric feature, what insights can we gain into the statistical distribution of its observations?
Median, mean, mode, first and third quartiles describe a statistical distribution because these are the measures of central tendency and dispersion of a distribution.
Median, mode and mean are known as the measures of central tendency of a statistical distribution. Because these three can even represent the whole data and its properties. Mean, median and mode gives the central value around which the whole distribution lies or its representative value.
Mean: It gives the average value of the distribution. That is the Total value/ Total number of values.
Median: It is a positional average and it is the middle value of the observations in a distribution.
Mode: Mode is also a positional average which gives the most repeated or frequent observation from the distribution
Now the first and third quartiles are measures of dispersion. It gives the variation of data values from the central value. It gives an idea of the scattering of the distribution around the central value.
First quartile: If the n observations are arranged in ascending order, then the n/4th value is the first quartile.
Third Quartile: It is the 3n/4th value in the ordered n observations.
These two are used to measure the quartile deviation from the central value. If the dispersion is large, then the measures of central tendency cannot be a representative value of the distribution.

The time it takes the driver to travel from Point A to Point B is 8 minutes, the same as the helicopter but through a more longer path, such that, we have;
The helicopter travels slower than the driverHow can the speed of the helicopter and the car be compared?Based on a similar question, the first part required to determine if a driver that drives from Point A to Point B in 8 minutes obeyed the speed limit of 55 miles per hour.
The path of the driver consists of a short path, a bend changing the direction, then a long straight path.
The path of the helicopter is directly from Point A to Point B.
Therefore;

The slope of the line in the given graph = rise/run = 3.
How to Find the Slope of a Line?To determine the value of the slope of a line on a coordinate plane, we can find the ratio of the rise of the line to that of its run. This means that, the formula for calculating the slope of a line would be:
Slope = rise/run.
Vertical distance across the line is the rise of the line
Horizontal distance across the line is the run of the line
In the graph given, we have:
The rise is labelled as the blue line = 9 units
The run is labelled as the red line = 3 units
Slope of the line (m) = 9 units/3 units
Slope (m) of the given line = 9/3 = 3

Applying the tangent ratio, the length of side x, in simplest radical form is: 8√3.

Given the following:
Reference angle (∅) = 30 degrees.
Opposite side length = 8
Adjacent side length = x = ?
Using the tangent ratio, we have: tan 30 = 8/x
x(tan 30) = 8
Divide both sides by tan 30
x(tan 30)/tan 30 = 8/tan 30
x = 8/tan 30
