3x + 4 = 1

3x + 4 - 4 = 1 - 4

3x = -3

3x/3 = -3/3

x = -1

The solution of the equation 3x + 4 = 1 is -1.

The answer is:

C) x = -1

Work/explanation:

To solve this equation, I subtract 4 from each side:

\(\sf{3x+4=1}\)

Subtract :

\(\sf{3x=-3}\)

Divide each side by 3:

\(\sf{x=-1}\)

Hence, C is correct.

The area of the composite figure is 122.24 units².

The composite figure consist of a rectangle and two semi circles. Therefore, the area of the composite figure is the sum of the area of the individua shapes.

Hence,

area of the composite figure = area of the rectangle + 2(area of semi circle)

Therefore,

area of the composite figure = 9 × 8 + 2(1 / 2 πr²)

area of the composite figure = 72 + πr²

where

r = 8 / 2 = 4 units

Therefore,

area of the composite figure = 72 + 3.14 × 4²

area of the composite figure = 72 + 3.14 × 16

area of the composite figure = 72 + 50.24

area of the composite figure = 122.24 units²

Step-by-step explanation:

To determine the constant of proportionality (k) in a proportional relationship, we need to compare corresponding values of x and y and calculate the ratio between them.

Let's examine the given values:

2. UX: x 6 15 9 y 42 200

To find the constant of proportionality (k), we can take any pair of corresponding values and calculate their ratio. Let's choose the first pair: (6, 42).

k = y / x

k = 42 / 6

k = 7

So, the constant of proportionality (k) is 7.

Now, let's find the missing values for the second set of values:

d. X: 14 y: 21 6 15 3 7 8

Since we know the constant of proportionality is 7, we can calculate the missing values of y by multiplying each corresponding x value by 7.

Missing values for y:

- For x = 21, y = 21 * 7 = 147

- For x = 6, y = 6 * 7 = 42

- For x = 15, y = 15 * 7 = 105

- For x = 3, y = 3 * 7 = 21

- For x = 7, y = 7 * 7 = 49

- For x = 8, y = 8 * 7 = 56

Therefore, the missing values of y are: 147, 42, 105, 21, 49, and 56.

Answer:

Daniel traveled further by 2.73 miles

Step-by-step explanation:

To find the total distance traveled simply multiply average speed times time

For Wendy

She traveled for 3.9 hours at a speed of 68.3 mph

So total distance traveled = 3.9 * 68.3 = 266.37 miles

For Daniel

He traveled for 4.5 hours at a speed of 59.8 mph

So total distance traveled = 4.5 * 59.8 = 269.1 miles

As you can see Wendy traveled 266.37 miles and Daniel traveled 269.1 miles

Daniel traveled further

To find how much further we simply subtract distance Daniel traveled (269.1) from distance Wendy traveled (266.37)

269.1 - 266.37 = 2.73

So Daniel traveled further by 2.73 miles

Step-by-step explanation:

the length of the diagonal of the suitcase is 30 in.

pythagorean theorem: a^2+b^2=c^2

(the length times the height=the diagonal)

So, 24^2 + 18^2=something

24^2=576

18^2=324

576+324= 900

square root of 900=30

so, c equals 30

therefore the diagonal =30 , so there's plenty of space to put the umbrella because it's less long than the diagonal

It will take 12 weeks for Praisys corn to be ready for picking.

We have been given that,

 Maya plants corns In = 4 rows

 Praisy plants corns in  = 6 rows

Maya corns ready to be picked in = 8 weeks

We have to find the number of weeks will it take Praisys corn to be ready for picking.

To find we will use the unitary method that is,

            4 rows = 8weeks

            6 rows = 8/4*6 weeks

A percentage is a number or ratio expressed as a fraction of \(100\). It is often denoted using the percent sign, "%".

Hence,

the amount desired at end of a period is $\(9400\).

The length of time is \(4 years\).

The rate is \(2\)%.

Compounded is monthly.

The period used is \(48\).

The rate used is \(1\)%.

The PV factor used is \(0.62026\).

The PV of the amount desired at the end of the period is $\(5830.45\)

What is the percentage?

A percentage is a number or ratio expressed as a fraction of \(100\). It is often denoted using the percent sign, "%".

Here from the question,

PV factor \(=(1+i)^{-n} ........(1)\)

where, \(i=\frac{12}{12}\)%

\(i=1\)

and

\(n=4(12)\\n=48\)

Substituting the values in the equation \((1)\), we get

PV factor \(=(1+0.01)^{-48}\\\)

PV factor \(=0.62026\)

Hence,

the amount desired at end of a period is $\(9400\).

The length of time is \(4 years\).

The rate is \(2\)%.

Compounded is monthly.

The period used is \(48\).

Step-by-step explanation:

4x+3y = 6

8x + 6y = 5

Multiply the first equation by -2

-8x -6y = -12

Add this to the second equation

-8x-6y = -12

8x + 6y = 5

Answer:

X = 8/3, y= -14/9

Step-by-step explanation:

using elimination method:

subtract equation 1 from equation 2

8x-4x + 6y-3y = 5-6

4x+3y= -1

4x= -1-3y

divide both sides by 4

x = -1-3y÷4

substitute x = -1-3y/4 in equation 2

8(-1-3y)/4 +6y = 5

-8-24y/4+ 6y =5

-8-24y+6y/4 =5

-8-18y/4 = 5

Cross multy

-8-18y × 1 = 4×5

-8-18y = 20

collect like terms

-18y = 20+8

-18y = 28

divide both sides by-18

y = 28/-8

y = -14/9

put y = -14/9 in equation 1

4x+3(-14/9) = 6

4x-42/9 = 6

42/9 = 14/3

so, 4x=6+14/3

LCM =3

4x = 18+14/3

4x= 32/3

cross multiply

4x×3 = 32

12x = 32

divide both sides by 12

12x/12= 32/12

x = 8/3

so, x = 8/3, y = -14/9

check:

first equation:

4(8/3) + 3(-14/9)

32/3 - 14/3( 3 cancels 9 rem 3)

LCM= 3

32 - 14/3

= 18/3

Answer:

Step-by-step explanation:

You want to know which of the relations shown is a function.

The rule is pretty simple. A relation is a function if each element of the domain maps to exactly one range value.

If an element of the domain maps to two or more range values, the relation is not a function.

In the attachment, we have identified what you would look for to determine that the relation is not a function. The map of a function has one arrow from each domain value. The ordered pairs of a function have no repeated first-values.

Answer: \(g^{-1} (8)=-3\)

\(h^{-1}(x)=\dfrac{x-2}{3}\)

\((h^{-1} \circ h)(-3)=-3\).

Step-by-step explanation:

Given: The one-to-one functions g and h are defined as follows.

g=((-5, 2),( -3, 8), (-1, - 8), (8, 9))  [here each x= input values , y= output values in (x,y)]

h(x)=3x+2

To find: \(g^{-1} (8)\)

As for 8 is a image of -3 ( from point ( -3, 8)).

So, \(g^{-1} (8)=-3\)

To find : \(h^{-1} (x)\)

Let \(y = h(x)=3x+2\)                                  (i)

Then,

 \(y=3x+2\Rightarrow\ 3x= y-2\\\\\Rightarrow\ x=\dfrac{y-2}{3}\)

Switch \(y\) with \(x\) and \(x\) with \(h^{-1} (x)\), we get

\(h^{-1}(x)=\dfrac{x-2}{3}\)                                            (ii)

To find : \((h^{-1} \circ h)(-3)\)

Consider \((h^{-1} \circ h)(-3)=h^{-1} (h(-3))\)

\(=h^{-1}(3(-3)+2)\ \ (using\ (i))\\\\=h^{-1}(-9+2)\\\\=h^{-1}(-7)\\\\= \dfrac{-7-2}{3}\ \ (using\ (ii))\\\\=\dfrac{-9}{3}=-3\)

So, \((h^{-1} \circ h)(-3)=-3\).

The symbolic quantified statement is given as:

For all real integers x and y, if x³ = y³, then x = y.

Using quantifiers, this can be written as:

∀x,y∈ℝ, (x³ = y³) → (x = y)

The symbolic quantified statement represents the original sentence using logical symbols and quantifiers.

The universal quantifier (∀) is used to denote "for all," while the implication arrow (→) represents "if... then." The statement asserts that if the cubes of any two real integers x and y are equal, then x and y are equal as well.
