Answer:

-0.3x

Step-by-step explanation:

if you divide all of the number up you will get -0.3x

Answer:

Not possible

Step-by-step explanation:

The reason why its not possible is because to figure out a x type of problem, there needs to be a answer to it.

Lets try it solve it to make better sense.

10/3 = 3.33333333333

-5/2 = -2.5.

Divide.

= -1.33333333333.

If this is possible, the answer is -1.33333333333.

Fraction = -4/3.

Answer:

3

Step-by-step explanation:

f(x) = 4x^3 – 13x^2 + 9x + 2

This looks complicated but all we need to find are the Roots

We are looking for when y=0

So given each part of the information, we can label how many times it happens

The function starts from the bottom of quadrant 3: Starts lower left

and goes up through the x-axis at (0, negative 0.25) : This is ONE ROOT

and then through the y-axis at (0, 2). : It's now on the 2nd quartile

It then starts to curve down at (0.5, 4): It's moving towards y=0

until it reaches (1.75, negative 0.5).: It has now passed y=o and there are TWO ROOTS

It then curves up and crosses the x-axis at (2, 0) and goes up approaching x = 3: It has passed y=0 again, so there are THREE ROOTS

This polynomial function has 3 ROOTS

EDGE 2023

Step-by-step explanation:

The given expression is :

10x + 45x - 13 = 11(5x + 6)

We can simplify it as follows :

Opening parenthesis on RHS

10x + 45x - 13 = 55x + 66

Taking like terms together,

55x-55x = 13+66

0 = 13+66

The given expression has no solution, as the variable cancels out woh each other. It is a meaningless expression.

Answer:

x=7

y=14

Step-by-step explanation:

this is a special 30-60-90 right triangle bc there is a right angle marker and a 60 degree and 30 degree angle

in 30-60-90 right triangles the short leg is x, the long leg is x√3, and the hypotenuse is 2x

it is given that the long leg is 7√3, and since the long leg equals x√3, then x equals 7

so the short leg, x, is 7  and since the hypotenuse is 2x, 2(7) =14

Answer:

x=-1

Step-by-step explanation:

Step 1: Subtract x from both sides.

−x+4−x=x+6−x

−2x+4=6

Step 2: Subtract 4 from both sides.

−2x+4−4=6−4

−2x=2

Step 3: Divide both sides by -2.

−2x/−2= 2/−2

x=−1

The function with the domain is given by f ( x ) = 2x + 3

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is

Let the x values be x = { -7 , -1 , 3 , 4 , 7 )

Let the y values be y = { -11, 1 , 9 , 11 , 17 }

Now , the function is given as  

f ( x ) = 2x + 3   be equation (1)

when x = -7

y = 2 ( -7 ) + 3

y = -11

when x = 7

y = 2 ( 7 ) + 3

y = 17

Hence , the function is f ( x ) = 2x + 3

Answer:

No

Step-by-step explanation:

Given that:

Total number of cups of trail mix available for camping trip = [tex]6\frac{1}{2}[/tex]

Amount of one serving contains = [tex]\frac{3}{4}[/tex] cups

Number of people at the trip = 12

To find:

Whether each person will be able to get the servings?

Solution:

Here, we can find the total number of servings by dividing the total number of cups of trail mix with the amount of one serving.

First of all, let us convert the mixed fraction into fractional number.

[tex]6\dfrac{1}{2} = \dfrac{6\times 2+1}{2} = \dfrac{13}{2}[/tex]

Therefore, total number of servings available as per the given quantities:

[tex]\dfrac{\frac{13}2}{\frac{3}4}\\\Rightarrow \dfrac{13\times 4}{2\times 3} \\\Rightarrow \dfrac{26}{3}\\\Rightarrow \approx 8[/tex]

So, With this type of servings Zoey will be able to serve only 8 people.

Therefore, there is not enough servings.

Answer:

4 weeks

$28

Step-by-step explanation:

Let

x = number of weeks

Jamal's savings = 18 + 5x

Samuel's savings = 10 + 7x

Equate both savings

Jamal's savings = Samuel's savings

18 + 5x = 10 + 7x

18 - 10 = 7x - 5x

8 = 2x

x = 8 / 2

= 4

x = 4 weeks

Check:

18 + 5x

18 + 5(2)

18 + 10

= $28

Each boy would have saved an equal amount of $28 at the end of the 4th week

[tex]Each\ Weight = \frac{1}{4}[/tex]lb

Step-by-step explanation:

Given

[tex]Weights = \frac{3}{4}lb[/tex]

[tex]Bananas = 3[/tex]

Required

Determine the weight of each

To do this, we simply divide the total weight by the number of bananas.

[tex]Each\ Weight = \frac{3}{4}/3[/tex]

Convert to multiplication

[tex]Each\ Weight = \frac{3}{4} * \frac{1}{3}[/tex]

[tex]Each\ Weight = \frac{1}{4}[/tex]

Hence, each banana weighs 1/4 of a pound
