Answer:

B

Step-by-step explanation:

f(x) is just another way of saying y, so this function is really y=4x-5. So if you do y+3 then the y intercept will increase by 3 shifting the graph up 3 units.

x = y /4 − 7 /4

Answer:

0.5

Step-by-step explanation:

the sum of the probabilities of the outcome should equal 1

Probability the outcome is not A = sum of probabilities of the outcome - probability the outcome is A

1 - 0.5 = 0.5

Answer:

B

Step-by-step explanation:

Answer:

f(x) = 4x - 1

Step-by-step explanation:

The answer to this question is f(x) = 4x - 1 because function notation displays the values of how the input of x yields the output of y. This means that in this form, y is changed to the x input where the substitution of the x in the equation yields the new y.

Answer:

aₙ = -2aₙ₊₁

Step-by-step explanation:

According to the sequence given 16, -8, 4, ...

a1 = 16

a2 = -8

a3 = 4

From the values, we can conclude thst;

a1 = -2(-8)

Since a2 = -8, then;

a1 = -2(a2)

Similarly

a2 = -2(4)

a2 = -2a3

The subsequent sequence are;

a3 = -2a4

The nth term will ne;

aₙ = -2aₙ₊₁

Hence the required recursive function is aₙ = -2aₙ₊₁

The recursive formula for the given sequence is

[tex]a_{n}=-\frac{1}{2} (a_{n-1})\\[/tex]

Given :

The terms of the sequence are  16, -8, 4, ...

Lets find the difference between the terms

[tex]-8-16=-24\\4-(-8)=12[/tex]

There is no common difference. So this is not an arithmetic sequence

Now we check common ratio'

[tex]\frac{-8}{16} =-\frac{1}{2} \\\frac{4}{-8} =-\frac{1}{2} \\[/tex]

The common ratio is -1/2

Now we write recursive formula

[tex]a_{n}=r(a_{n-1})[/tex]

Where 'r' is the common ratio

[tex]a_{n}=r(a_{n-1})\\a_{n}=-\frac{1}{2} (a_{n-1})\\[/tex]

The recursive formula is

[tex]a_{n}=-\frac{1}{2} (a_{n-1})\\[/tex]

Answer:

The value of x = 36°, while the value of y = 72°.

Step-by-step explanation:

All of these angles add up to 360°.

Opposite angles are always equivalent, so the angle opposing x would be 36°, which means x = 36°.

360 - 2(36) = 288

288/4= 72

To check:

(72 * 4) + 2(36) = 360

Answer:

The leading coefficient, a.

Step-by-step explanation:

In a quadratic equation:

y = a*x^2 + b*x + c

The leading coefficient is the coefficient hat that multiplies the variable with the highest power.

In this case, is easy to see that the leading coefficient is a.

We call this the "leading" coefficient because is the coefficient that most impact has on the equation's behavior.

In the case of the quadratic equation, we know that x^2 is always a positive number and is the part that grows faster.

Then if a is a positive number, a*x^2 will be positive, and because this is the part that grows faster, the arms of the parabola will open upwards.

If a is negative, then a*x^2 will be negative, and this will cause that the arms of the parabola open downwards

Then the sign of a defines the direction of the parabola.

And a also defines the width of the parabola.

If a is a really larger number, then

a*x^2 grows really fast

This means that in a small increase of x, we may see a large increase in y, so we will have a "thin" parabola.

On the other hand, if a is really small, a large increase of x will not cause a large increase on y, so we will see a wider parabola.

Then the coefficient a (or variable, depending on which thing are you changing) is the one that controls the parabola's direction and width.

Step-by-step explanation:

7+2=9

Step-by-step explanation:

LET THE Point 1 A and point 2 is B

(AB) ^2=(-9-(-3))^2+ (5-(-6))^2+(-4-7)^2=278

AB=16.67 length unit

Midpoint

X=-9-3/2 =-6

Y=5-6/2=-0.5

Z=-4+7/2=-1.5

The distance between points (−3,−6,7) and (−9,5,−4) is 16.6 units, and midpoints are (-6, -0.5, -1.5).

Distance between two points (x₁, y₁, z₁) and (x₂, y₂, z₂) is determined by the following as D² = (x₂-x₁)² + (y₂-y₁)² + (z₂-z₁)²

The midpoint of the line joining  (x₁, y₁, z₁) and (x₂, y₂, z₂)  is given by :

{(x₂+x₁)/2 , (y₂+y₁)/2 , (z₂+z₁)/2}

To determine the distance between points (−3,−6,7) and (−9,5,−4)

Let mid points X, Y, and Z

The given points :  (−3,−6,7) and (−9,5,−4)

Distance between points  (−3,−6,7) and (−9,5,−4) :

D² = (x₂-x₁)² + (y₂-y₁)² + (z₂-z₁)²

D² =(-9-(-3))²+ (5-(-6))²+(-4-7)² = 278

D = √278

D = 16.6 units

The midpoint of the line joining (−3,−6,7) and (−9,5,−4) :

X = (-9-3)/2 = -6

Y =(5-6)/2 = -0.5

Z =(-4+7)/2 = -1.5

Hence, the distance between points (−3,−6,7) and (−9,5,−4) is 16.6 units, and midpoints are (-6, -0.5, -1.5).

Answer:

18.326 inches

Step-by-step explanation:

The question is basically asking us to find the arc length that the tip of the minute hand travels. The formula for an arc length is S=θr. So we need th find the angle that the minute hand passes through. We know that there is 360 degrees in a cicle and there is 12 stops around a clock, so divide 360 by 12 to find the degrees the minute hand travels every 5 minutes. We ge that every 5 minutes the hand travels 30 degrees, and 35 minutes is 7*5 so we multiple 30*7 to find the angular displacement, and we get 210 degrees. This equation uses radians though so we have to convert, which can be done doing [tex]\frac{210}{1} *\frac{\pi }{180}[/tex], and we ge that θ is [tex]\frac{7\pi }{6}[/tex] so ([tex]\frac{7\pi }{6}[/tex])(5)= 18.326 inches

Step-by-step explanation:

First, we set up our equation: To find the area of a trapaziod, the equation is Base 1+ Base 2 times Height

So, the equation would be: A=26+46x19

A=72x19

72 times 19= 900

Answer:

To find the perimeter of a polygon, you just have to add the values of each side.

For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.

17. See below

18. 750

Step-by-step explanation:

17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.

18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:

[tex]y=0.5x+125[/tex]

Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:

[tex]500=0.5x+125[/tex]

[tex]500-125=0.5x[/tex]

[tex]375=0.5x[/tex]

[tex]\frac{375}{0.5} =x[/tex]

[tex]375*2=x[/tex]

[tex]750=x[/tex]

Thus, 750 lollipops must be sold.

Indian system of numeration:

With the Indian system, when writing a million, a comma comes after the first three digits and then after 2 digits from thenceforth.

For instance, a million would be:

= 10,00,000

Distance to moon in Indian numeration = 3,84,014 km

International System of Numeration:

Here a comma separates a maximum of 3 digits. A million here would be:

= 1,000,000

Distance to moon is therefore:

= 384,014 km
