Answer:

14^2

Step-by-step explanation:

i just plugged into calculator lol

Given expression:

                    14⁶   /   14⁴

   Using the exponent rule;

               [tex]\frac{x^{n} }{x^{m} }[/tex]   = [tex]x^{n-m}[/tex]

  So;

                 x  = 14

                 n = ⁶6

                  m = 4

So;

         [tex]\frac{14^{6} }{14^{4} }[/tex]  = 14⁶⁻⁴

                = 14²

Step-by-step explanation:

We have that the vertices of triangle ABC are:

A(4, 2)

B(7, 9)

C(7, 2)

First, we are reflecting over the y axis, which makes (x,y) map onto (-x, y). This gives us:

A'(-4, 2)

B'(-7, 9)

C'(-7, 2)

Then, we translate 5 units down, meaning we subtract 5 from each of the y coordinates. This gives us a final answer of:

D(-4, -3)

E(-7, 4)

F(-7, -3)

L = lengh

W = width

french reasoning ( hello from France ) !

The base of the house is a rectangle where the length of a rectangle is 8 more than the width.

=> L = W + 8

and

Its area is 240 ft sq

W x L = 240

L = W + 8

W x L = 240

=> W x (W+8) = 240

W² + 8W - 240 = 0

Δ = 8² - 4*1*(-240) = 32²

W' = (-8 + 32) / 2 = 12 ft

W'' = (-8 - 32) / 2 = impossible

at the end

W the width = 12 ft

and then the lengh = 12 + 8 = 20

area = 12 x 20 = 240 ft²

Answer:

900 acres of wheat

1350 acres of corn

750 acres of oats

Step-by-step explanation:

3000 = 100%

÷ 10 both sides

300 = 10%

× 3

900 = 30%

300 = 10%

× 4

1200 = 40%

300 ÷ 2 = 150 (5%)

1200 + 150 = 1350

1350 + 900 = 2250

3000 - 2250 = 750

Step-by-step explanation:

Graph of a function is plotting of its input and corresponding output. The graph of the considered cubic function is attached below.

Suppose the considered function whose graph is to be made is [tex]f(x)[/tex]

The values of 'x' (also called input variable, or independent variable) are usually plotted on horizontal axis, and the output values [tex]f(x)[/tex]

are plotted on the vertical axis.

They are together plotted on the point

[tex](x,y) = (x, f(x))[/tex]

This is why we usually write the functions as:

[tex]y = f(x)[/tex]

For the considered function [tex]f(x) = x^3 +x^2 +x + 1[/tex] is attached below.

Answer: Ayden has 11 football cards,44 baseball cards and 51 Pokemon cards which totals  106 cards all together

Step-by-step explanation:

STEP 1 :

Let x represent number of football cards

He has four times as many baseball cards as football cards, let baseball cards be = 4x

Pokémon cards contain 7 more cards than his baseball collection,let Poke mon cards = 4x +7

Step 2 :

Putting in equation we have that

Football cards + Baseball cards + Pokemon cards = 106 cards

Therefore,

x + 4x + 4x+7 = 106

9x + 7 = 106

9x = 106-7

9x = 99

x =99/9 = 11

therefore football cards , x = 11 football cards

 baseball cards = 4x = 4 x 11 = 44 baseball cards

Pokemon cards = 4x+7= 4x11 +7 = 44 +7 =51 Pokemon cards

Answer:

$3.70

Step-by-step explanation:

0.2 x 6 = 1.2

1.2 + 2.5 = 3.7

If the slope of the line is 7 /10, the vertical change that will be present for a horizontal change of 63 ft is 44.1 ft

The slope of a line is the measure of its steepness. Therefore,

slope = change in y(vertical) / change in x(horizontal)

slope = y₂ - y₁ / x₂ - x₁

slope = 7 / 10

Therefore,

7  / 10 = y / 63

cross multiply

441 = 10y

divide both sides by 10

y = 441 / 10

y = 44.1 ft

Answer:

Delivery Trip: 3 hours

Return Trip: 4 hours

Step-by-step explanation:

d/60 + d/45 = 7

45d/2700 + 60d/2700 = 7

105d/2700 = 7

105d = 18900

d = 180

180/60 = 3

180/45 = 4

Answer:

delivering 180/45 = 4 hours and return trip 180/60 = 3 hours

Step-by-step explanation:

d = unknown number to calculate each trip

[tex]\frac{d}{45}[/tex] + [tex]\frac{d}{60}[/tex] = 7

find common denominator (45 * 60 = 2700)

([tex]\frac{60}{60}[/tex])*([tex]\frac{d}{45}[/tex]) +( [tex]\frac{45}{45}[/tex])*([tex]\frac{d}{60}[/tex]) =7

[tex]\frac{60d}{2700}[/tex] + [tex]\frac{45d}{2700}[/tex] =7

[tex]\frac{60d + 45d}{2700}[/tex] =7

[tex]\frac{105d}{2700}[/tex] = 7

105d = 7 * 2700

105d = 18,900

d = 18900/105

d = 180

delivering 180/45 = 4 hours

return trip 180/60 = 3 hours

Answer:

Step-by-step explanation:

Replace x with 3, and multiply the number next to it.

5(3)= 15

3(3)=9

so, 15-3+9+7=28

Answer:

28

Step-by-step explanation:

To solve this, replace every x with (3). If x is next to a number, that means you multiply that number and the value of x. This gives us the equation 5(3)-3+3(3)+7. When a set of parentheses are next to a number, you multiply. 5 times three is 15, and 3 times 3 is 9. This gives us 15-3+9+7. 15 - 3 is 12. 12 + 9 is 21. 21 + 7 is 28. 28 is your answer.

Answer:

27 units

Step-by-step explanation:

let t represent time and n represent number of units

given t is directly proportional to n then the equation relating them is

t = kn ← k is the constant of proportion

to find k use the condition t = 22, n = 18 , then

22 = 18k ( divide both sides by 18 )

[tex]\frac{22}{18}[/tex] = [tex]\frac{11}{9}[/tex] = k

t = [tex]\frac{11}{9}[/tex] n ← equation of variation

when t = 33 , then

33 = [tex]\frac{11}{9}[/tex] n ( multiply both sides by 9 )

297 = 11n ( divide both sides by 11 )

27 = n
