-57 + 57 I really need the answer

Answer: Alternate interior angles and congruent angles.

Step-by-step explanation: The angles are formed when a line cuts two transversals, and they’re inside the two lines, meaning that they are congruent and alternate interior angles.

Answer:

y = (4/5)x + 16

Point-slope form:

y - 12 = (4/5)(x + 5)

Step-by-step explanation:

slope = m; (-5, 12)

m = (4/5)    (x₁, y₁)

y - y₁ = m(x - x₁)

y - 12 = (4/5)(x - (-5))

y - 12 = (4/5)(x + 5)

y - 12 = (4/5)x + 4

  +12                +12

--------------------------

y = (4/5)x + 16

I hope this helps!

The equation of a line into slope-intercept form is represented as:

y = mx + c

where m = slope of the line

c = y-intercept of the line

On simplifying 8x - 20y = 40, the equation will be:

⇒ 2 (4x - 10y) = 2 (20)

⇒ 4x - 10y = 20

⇒ 2x - 5y = 10

⇒ 2x - 10 = 5y

⇒ 5y = 2x + (-10)

⇒ y = 2x/5 + (-10/5)

⇒ y = 2x/5 + (-2)

The slope of this line = 2/5

y-intercept of the line = -2

The estimated population is found to be 48 rabbits

The estimated population, P is determined by using the following formula:

[tex]P=T_{F} *T_{L} /M[/tex]

P=estimated population

[tex]T_{F}[/tex]=total animals captured in first trapping

M=recaptured animals that are marked

[tex]T_{L}[/tex]=total animals captured in a later trapping

From the question, [tex]T_{F}[/tex]=20 rabbits, M=5 rabbits, [tex]T_{L}[/tex]=12

P=20*12/5

P=240/5

P=48 rabbits

Hence, the estimated population is 48 rabbits

The number of miles that Mark ran was 50 miles.

We can get the number of miles that Mark runs by first assigning him the figure x.

Since DeSahwn ran 40. 7 miles less than Mark, we can express this thus:

x - 40. 7 miles.

If the number of miles that DeShawn ran was 9.3 miles we can factor that into the equation as follows:

x - 40. 7 miles = 9.3 miles

x = 9.3 + 40.7

x = 50 miles.

Therefore, the total number of miles that Mark ran was 50 miles.

Answer:

First and Third

Step-by-step explanation:

The graphs obey the function equations but the intervals are marked incorrect in #s 2 and 4

One thing to keep in mind is that when you have a piecewise function valid on certain intervals, the circle shape denoting the beginning of the interval is very important

If it is a filled circle it denotes a ≤ (or ≥) inequality

If it is an unfilled (hollow) circle it denotes a < (or >) inequality

Looking at the second graph we see that

f(x) = -1 for -∞ < x < -1
Assuming the interval is correctly defined, that solid circle at x = -1, y = -1 should be a hollow circle not a filled circle

Similarly for f(x) = 3x² + 3, the interval is given as -1 ≤ x < ∞ but the starting circle for this interval is an unfilled circle, it should be a filled circle

A similar situation applies to the fourth choice and you should be able to figure that out yourself

The given statement "The different between the upper class limit and lower class limit is called width of the class intervals" is True

Frequency distributions should normally contain 5 to 20 equal-width classes, be continuous, exhaustive, and mutually exclusive.

Clarification of the quoted phrase,

The breadth or size of the class interval in a frequency distribution table is the distance between the upper and lower class limits.

A class interval, for instance, is any of the groups 20–25, 25–30, 30-35, etc. There is a five-point spread between the upper and lower limits. the class width is therefore 5.

As a result, the assertion is true.

A portion of a square and a portion of a circle were used to create this figure. The perimeter of the figure is 36.28 units.

Given that,

A portion of a square and a portion of a circle were used to create this figure.

We have to find the perimeter of the figure.

Three linear sides are measured in units of 4, 8, 8, 4.

Radius of the circular part = 4 units

Measure of a polygon's circumference equals the polygon's perimeter.

From the figure we can see,

Figure perimeter equals the sum of the lengths of the three straight lines and the circumference of the quarter circle.

Measure of linear sides = 4 + 8 + 8 + 4 = 24 units

Circumference of the quarter circle = 1/4(2πr)

=1/2×π×4

=2×π

=2×3.14

Matilda arrives home at 18.45 after driving 42 kilometers from her workplace at an average speed of 56 km/h.

The time Matilda uses to drive home from her workplace is a function of the distance she travels and the average speed she goes.

Using the above formula gives us the time in hours/minutes that she took for the home drive.

This derived time is then added to the time she leaves her workplace to get the time she arrives home using the 24-hour clocking system.

The time Matilda leaves her workplace = 18:00

The total distance Matilda travels from work to her home = 42 km

The average driving speed that Matilda traveled with = 56 km/h

Time used for driving home (in hours) = Distance/Speed

= 42/56

= 0.75 hours

= 45 minutes (0.75 x 60)

Arrival Time = 18:45 (18:00 + 45)

Thus, using the 24-hour clocking system, the time Matilda is expected to reach her home is 18:45.
