Answer:

∠6 = 61°

Step-by-step explanation:

In order to solve this, you need to know what "vertical angels" are. Based on the fact that the angle that is 61° and angle 6 make a pair of vertical angles, we know that both of these angles are equal to each, therefore ∠6 = 61°.

Answer:

A) 2 9

Step-by-step explanation:

got it right on edge :) good luck!

Limit of f (x) = 2 as x approaches 1 minus. Limit of f (x) = 9 as x approaches 1 plus.

The correct option is (A)

Piecewise function is a function built from pieces of different functions over different intervals.

The given function is: f(x)= [tex]\left \{ {{2x, \;\; x < 1} \atop {-4, \;\; x=1} \right \atop {x+8, \;\; x > 1}[/tex]

As,  piecewise function is a function built from pieces of different functions over different intervals.

As per the above discussion we can say that,

Take function for limit 1 minus, as f(x)  = 2x

put x=1,

f(x)=2, exits.

Take function for limit 1 plus, as f(x)  = x+8

put x=1,

f(x)=9, exits.

As both satisfies the definition and part (A)

As well as both limit exist and are not equal.

So, Limit of f (x) = 2 as x approaches 1 minus. Limit of f (x) = 9 as x approaches 1 plus for the given f(x).

Answer: System 1 has an infinite number of solutions and System II has no solutions.

Step-by-step explanation:

If we look at system 1, we see that if we multiply the first equation by 2 and subtract the y value so that its on the same side as x, the equations are the same. That means that no matter the x or y value, it will be a solution.

If we look at system 2, however, we see that if we multiply the top equation by 3, the equations are the exact same except for the fact that the top equation has a -21. This means that no matter the x or y, there will never be a solution.

f(4) = -18

g(-3) = -76

Step-by-step explanation:

f(x) = -5x + 2

f(4) = -5(4) + 2

= -20 + 2

= -18

g(x) = 3x^3 + 5

g(-3) = 3(-3)^3 + 5

= 3(-27) + 5

= -81 + 5

= -76

Answer:

F(4)= -18

G(-3)=-76

f(x)= -5x+2

g(x)=3x^3+5

To find f(4), wherever you see x in f(x) put in 4

-5(4)+2= -18

To find g(-3), wherever you see x in g(x) put -3

3(-3)^3 +5= -76

Answer:

the answer is 10

Step-by-step explanation:

The difference between the range and the IQR of the data set represented by the box plot is 10.

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

The range of a dataset is calculated as the difference between the maximum and minimum values in the dataset.

In this case, the range is:

Range = highest value - lowest value = 34 - 16 = 18

The interquartile range (IQR) is the difference between the third quartile (Q3) and the first quartile (Q1). In this case, the IQR is:

IQR = Q3 - Q1 = 29 - 21 = 8

So the difference between the range and the IQR is:

Range - IQR = 18 - 8 = 10

Therefore,

The difference between the range and the IQR of the data set represented by the box plot is 10.

17) -4y + 16 = 6x

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, subtract 16 from both sides of the equation:

-4y + 16 (-16) = 6x (-16)

-4y = 6x- 16

Next, divide -4 from both sides of the equation:

(-4y)/-4 = (6x - 16)/-4

y = (6x)/-4 + (-16)/-4

y = -3x/2 + 4

Slope: [tex]-\frac{3}{2}[/tex]

~

18) 0 = -12y -36 + 15x

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First, add 12y to both sides of the equation:

0 (+12y) =  - 12y (+12y) + 15x - 36

12y = 15x - 36

Next, divide 12 from both sides of the equation to isolate the variable, y:

(12y)/12 = (15x - 36)/12

y = (5/4)x - 3

Slope: [tex]\frac{5}{4}[/tex]

~

19) 3x = -6y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Divide -6 from both sides of the equation:

(3x)/-6 = (-6y)/-6

y = 3x/-6

y = -(3/6)x

Simplify. Divide common factors from both the numerator and denominator.

-(3/6)/(3/3) = - 1/2

Slope: [tex]-\frac{1}{2}[/tex]

20) -2x -5 = -5y

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

Divide -5 from both sides of the equation:

(-2x - 5)/-5 = (-5y)/-5

y = (-2x - 5)/-5

y = (2/5)x + 1

Slope: [tex]\frac{2}{5}[/tex]

Answer:

y = -3x

Step-by-step explanation:

To get slope intercept, you divide both y values by both x values like this

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

In this case this will be [tex]\frac{(-3 - 6)}{(1 - (-2))}[/tex]

This will become [tex]\frac{-9}{3}[/tex]

Divide those two to get -3, and now you get your slope intercept.

Answer:

Step-by-step explanation:    First, let's call the starting elevation of the plane: e

We can then write an equation representing this problem as:    

e−1.5mi=5.25mi

Now, add 1.5mi  to each side of the equation to solve for e

while keeping the equation balanced:

e−1.5mi + 1.5mi=5.25mi + 1.5mi

e−0=6.75mi

e=6.75mi

The plane's starting elevation was 6.75 miles

Answer:

Here we have the function:

S(t) = 500 - 400*t^(-1)

Then the rate of change at the value t, will be:

S'(t) = dS(t)/dt

This differentiation will be:

S'(t) = -400/t^2

Then:

a) the rate of change at t = 1 is:

S'(1) =  -400/1^2 = -400

The rate of change after one year is -400

b) t = 10

S'(10) = -400/10^2 = -400/100 = -4

The rate of change after 10 years is -4, it reduced as the years passed, as expected.

Step-by-step explanation:

Subtract 2x from both sides of the equation.

X2-1=−2x

Add 1 to both sides of the equation.

X2=−2x+1

Take the square root of both sides of the equation to eliminate the exponent on the left side.

X=±√−2x-1

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the ± to find the first solution.
