If x varies inversely as y, which statement is true?

Answer:

b. 10a³ - 11a - 3

Step-by-step explanation:

1. Expand 3(a³ - 2a - 5)

= 3a³ - 6a - 15

2. Add 7a³ - 5a + 12 and 3a³ - 6a - 15

7a³ + 3a³ = 10a³

-5a + -6a = -11a

12 + -15 = -3

3. Answer: b. 10a³ - 11a - 3

Answer:

2nd option

Step-by-step explanation:

Given x = a is a root of a polynomial function then (x - a) is a factor

Given roots are x = 0, x = - 2, x = 7 , then corresponding factors are

(x - 0) , (x - (- 2) ) , (x - 7) , that is

x , (x + 2) , (x - 7)

The polynomial function f(x) is then the product of the factors, so

f(x) = x(x + 2)(x - 7)

Answer:

okay so..

Given

<2 = 110°

• <2 = <4 so <4 = 110°

Step-by-step explanation:

Solution

• <4 is equal with it's front facing angle(the angle next to <1) let's call that angle <x

<4 = <x = 110°

<x + <1 = 180°

110° + <1 = 180°

<1 = 180° - 110°

<1 = 70°

• <4 + <3 = 180°

110° + <3 = 180°

<3 = 180° - 110°

<3 = 70°

Answer:

circle area

Step-by-step explanation:

A full circle contains 360 degrees. So, an arc of 360 degrees would just be a circle.

The area of a sector is to the circle area

The area of a circle is:

[tex]A = \pi r^2[/tex]

The area of a sector is:

[tex]a = \frac{\theta}{360} * \pi r^2[/tex]

Substitute [tex]A = \pi r^2[/tex] in the above equation

[tex]a = \frac{\theta}{360} * A[/tex]

The above means that the area of a sector is a fraction of the circle area

Hence, the area of a sector is to the circle area

Step-by-step explanation:

Answer:

Paul has 6.6 miles to go after his snack.

Step-by-step explanation:

Speed is the rate of moving. The speed can be calculated by dividing the distance traveled by the amount of time it took.

speed= distance/time  , v=d/t

So,from Paul's average speed we can calculate how much distance he has passed after 3 hours.

distance_3h=v*t=13.8 miles per hour * 3 hours

distance_3h=41.4 miles

There are total 48 miles to the beach, so Paul have to go 48miles-distance_3h after his snack, which gives:

48-41.4=6.6 miles

Answer:

The correct result would be f(x) = 4(3.24)x.

Slope = -4

Step-by-step explanation:

Perpendicular lines have negative reciprocal slopes, which means that multiplying their slopes result in a product of -1. Given the equation, x - 4y = - 12:

Transform the equation into its slope-intercept form, y = mx + b:

x - 4y  = - 12

x - x - 4y = - x - 12

-4y = -x - 12

Divide both sides by -4:

[tex]\frac{-4y}{-4} = \frac{-x - 12}{-4}[/tex]

y =  ¼x + 3  ⇒ (This is the slope-intercept form of the given standard equation, x - 4y  = - 12).

Since the slope of the given equation is ¼, then it means that its negative reciprocal must be - 4:

(¼) (-4) = -1

Therefore, the slope of the line perpendicular to x - 4y = - 12 is - 4.

Step-by-step explanation:

Gabriel has 4 partners.

When you take the 4 and multiply it by 4, you get 16 where you'd take half of the 16 and add it to it. So you'd have 16 + 8 where it equals 24 and then add the original 4 and you get 28.

Step-by-step explanation:

shape BCD is an isosceles triangle meaning the base angles will be the same.

CA is a straight line meaning that it is 180

the sum of angles in a triangle always is 180

so

180-36= 144

to find x you need to half 144 as it is the sum of the base angles of the isosceles triangle.

144/2= 72

x=72

the angle just below y is also 72.

as CA is a straight line,

180-72= 108 giving you the answer for y

y= 108

so to make the answer clear

x= 72

y= 108

Step-by-step explanation:

so levt's label the video games as "P"

if 6P=207.54$

1P= X

1P × 207.54$ = 6P × X

1P × 207.54$ = 6P × X => P eliminates P on the right side

6P 6P. => 6P eliminates 6P on the left side

207.54$ = X

6

X = 34.59$

Step-by-step explanation:

Let the cost of 1 video game = x

6 video games = $207.54

1 video game = x........cross multiply

6x = 207. 54............ divide both sides by 6

x = 34.59

therefore, 1 video game costs $34.59

Answer:

First we need our slope equation

Y₂-Y₁/X₂-X₁

So we have our equation now lets plug it in

-9+2/-4-3 (we make it a plus for -9+2 because the two minuses cancel out).

So now we have -7/-7 which is 1 because -7 divided by itself is one. Thereby your answer is A. 1

Same thing for question 12

1-5/2-4

-4/-2 which is 2 because -2 goes into -4 two times so your answer is A. 2
