Answer: y = 4/9 x - 1/3

Step-by-step explanation:

standard form means y = mx + c

so,

4x-8=9y-5

4x-8+5=9y

(4x-3)/9=y

y = (4/9)x - (1/3)

The distance between in two cities is 360 miles.

Given,

It took a plane 2 hours to fly from Dallas to New York

The headwind and 1.5 hours to return with the tailwind.

and, the speed of the wind was 30 mph.

To find the how far apart are the two cities?

Now, According to the question:

Let speed of be x

Speed of wind be c

Also note D = RT, where

D is distance and R is rate and T is time

For First Leg:

we can write:

(x - c) × 2 = D

2x - 2c = D

For Second Leg:

we can write:

(x+ c) × 1.5 = D

1.5x + 1.5c = D

We can equate and write:

2x - 2c = 1.5x + 1.5c

0.5x = 3.5c

We know Speed of Wind, c, is 30, so we have:

0.5x = 3.5(30)

0.5x = 105

x = 105/0.5 = 210 [speed of airplane]

We know distance is

D = 2x - 2c

D = 2(210) - 2(30)

D = 420 - 60

D = 360 miles

Hence, The distance between in two cities is 360 miles.

The distance from the base of the ladder to the house is 15 ft.

The length of the ladder is 39 ft.

The ladder is placed to reach a point on the house 36 feet from the ground.

This situation forms a right angle triangle.

The distance from the base of the ladder to the house is as follows:

The distance from the base of the ladder to the house is the other leg of the right angle triangle.

The ladder length is the hypotenuse of the right triangle.

Hence, using Pythagoras theorem,

39² - 36² = b²

b² = 1521 - 1296

b² = 225

b = √225

b = 15 ft

Therefore, the distance is 15 ft.

Clare plans to fold up the sides of a poster board that is 30 inches by 25 inches of box. The volume V(x)=4x³-110x²+750x.

Given that,

Clare plans to fold up the sides of a poster board that is 30 inches by 25 inches and trim the corners to create an open-top box. The open-top box's volume, "V(x)," in cubic inches, depends on the square cuts' side length, "x," in inches.

Length =30 inch

Width=25 inch

The box's size changes when x is taken out of the container.

Length=30-2x

Width=25-2x

Height=x

Because x is eliminated from both ends, we subtract 2x.

The volume is then determined as follows:

V(x)=length×width×height

V(x)=(30-2x)×(25-2x)×x

V(x)=(30-2x)×(25x-2x²)

V(x)=750x-110x²+4x³

V(x)=4x³-110x²+750x

Therefore, the volume V(x)=4x³-110x²+750x.

To find, let  the no. of kg of mixed nuts that contains 40% peanuts be called  [tex]x[/tex].

We know,

Total peanuts already in the mixture = 18 x [tex]\frac{62}{100}[/tex] = 11.16 kg

The  new mixture contains 52% peanuts, then, [tex]\frac{x_{peanuts} }{x_{total} }[/tex] = 0.52.

Furthermore, 40% must be added.

[tex]x_{peanuts}[/tex] = [tex]0.4x[/tex] + [tex]11.16[/tex]

This gives us the following equation,

[tex]\frac{0.4x + 11.16}{18 + x } = 0.52[/tex]

Total mass =[tex]x + 18[/tex]

⇒ [tex]0.52 x +[/tex] 0.52 x 18 = [tex]0.4x + 11.16[/tex]

Answer:

10

Step-by-step explanation:

The number is 52. If you subtract 2 you get 50, then after dividing by 5 you get 10.

The value of x is -64.

An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values.

For example, 3x + 5 = 15.

Given:

n(x)=16-0.5x;

n(x)=48

So, equation both

48=16-0.5x

Now, add 0.5 both sides

0.5x+48=16

Now, subtract 48 both sides

0.5x=-32

Divide both side by 0.5

x= -64

Hence, the value of x is -64.

Each cow receives seven pounds of cow chow from Bob. Every time he feeds, farmer Bob uses at least 84 pounds of cow chow, which means that each time he feeds, 12 cows in total.

The unitary approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

Cow chow fed to each cow by the farmer =7 pounds

Total cow chow used by the farmer to feed the cows every time = 84 pounds

Total cow chow used = no. of cows *cow chow fed to each cow

No. of cows = Total cow chow / cow chow fed to each cow

                    = 84/7

                    =12

No. of cows = 12

The numbers that are greater than 59 1/3 are; C: 59 2/3 and D: 179/3

We want to find the numbers that are greater than 59 ¹/₃.

Now, the given fraction is written in mixed fraction. Looking at the fraction side, we can see that 1/3 can be written as 0.333. Thus;

59 ¹/₃ = 59.333

When we talk about the inequality greater than, we are simply referring to sayin that a figure is more than another figure which could be given or not given.

Looking at the given options, let us rewrite each of the mixed or improper fractions in decimal form to get;

59 ²/₁₀ converted to decimal form gives 59.2

59 ⁴/₁₂ = 59 ¹/₃  converted to decimal form gives 59.333

59 ²/₃  converted to decimal form gives 59.667

179/3 = 59 ²/₃  converted to decimal form gives 59.667

Inverse function of expression is [tex]\frac{1}{2}[/tex]x + 2.

An inverse in mathematics is a function that "undoes" another function. In other words, if f(x) produces y, then y entered into the inverse of f produces x. An invertible function is one that has an inverse, and the inverse is represented by the symbol f1.

In the broadest sense, inverse functions are functions that "reverse" one another. The inverse, f 1 f-1 f1f, start superscript, minus, 1, end superscript, must take b to a, for instance, if f takes a to b.
