Answer:

[tex]x = -0.8\ or\ x = 0.5[/tex]

Step-by-step explanation:

Given [Missing from the question]

[tex]6x^2 + 2x - 2.5 = 0[/tex]

Required

Solve

Using factorization, we have:

[tex]6x^2 + 2x - 2.5 = 0[/tex]

Expand 2x

[tex]6x^2 - 3x+5x - 2.5 = 0[/tex]

Factorize

[tex]3x(2x - 1)+2.5(2x - 1) = 0[/tex]

Factor out 2x - 1

[tex](3x +2.5)(2x - 1) = 0[/tex]

Split:

[tex](3x +2.5) = 0\ or\ (2x - 1) = 0[/tex]

In both cases, solve for x

[tex]3x = -2.5\ or\ 2x = 1[/tex]

[tex]x = -\frac{2.5}{3}\ or\ x = \frac{1}{2}[/tex]

[tex]x = -0.8\ or\ x = 0.5[/tex] --- approximated

Answer:

Jamal predicts that 243 people will visit his site on the fifth day.

Step-by-step explanation:

Since Jamal launched a website for his custom shoe store, and on the first day, 3 visitors registered on the website, while on the third day, 27 visitors registered on the website, if Jamal uses an exponential function to model the data from the first and third days, to determine how many visitors will predict to register on the fifth day, the following calculation must be performed:

Day 1 = 3

Day 2 = 3 ^ 2 = 9

Day 3 = 3 ^ 3 = 27

Day 4 = 3 ^ 4 = 81

Day 5 = 3 ^ 5 = 243

Therefore, Jamal predicts that 243 people will visit his site on the fifth day.

Answer:

Step-by-step explanation:

To find which bag weight Carla needs, the first step is to find the total weight of the bags shown in the line plot.

There are three -pound bags.

There are six -pound bags.

There are four -pound bags.

Multiply the weight and number of each bag to find the total weight of each different weight bag.

Now, add the three totals.

Finally, subtract the total weight from four pounds in order to find which weight Carla needs.

So, Carla should pick one -pound bag of candy to total four pounds.

Answer:

[tex]f(n)=-3n+24[/tex]

Step-by-step explanation:

A=(1,21)

B=(3,15)

slope:- Δy/Δx=21-15/1-3=6/-2= -3

Equation:-

y-y1=m(x-x1)

y-21=-3(x-1)

⇒y=-21=-3n+3

→ y= -3n+3

y= -3n+24

Answer:

y = -2/3 + 3

Step-by-step explanation:

y2 - y1 / x2 - x1

-3 - 1 / 9 - 3

-4 / 6

-2/3

y = -2/3x + b

1 = -2/3(3) + b

1 = -2 + b

3 = b

y = -2/3 + 3

Step-by-step explanation:

Answer:

x = 2

x < 2

x < 3

Step-by-step explanation:

2x + 5 = 9

Since there is an addition sign in front of 5, you must do the opposite: subtraction. Subtract 5 from 9.

9 - 5 = 4.

Lastly, divide the difference by the number in front of x (2).

2x = 4

4 ÷ 2 = 2

x = 2

--------------------------------------------------------------------------------------------------------------

2x + 5 < 9

Again, subtract 5 from 9.

9 - 5 = 4

Lastly, divide the difference by the number in front of the x (2).

2x = 4

4 ÷ 2 = 2

x < 2

--------------------------------------------------------------------------------------------------------------

4x - 5 < 7

Since there is a subtraction sign in front of the 5, you must do the opposite: addition. Add 5 to 7.

5 + 7 = 12

Lastly, divide the sum by the number in front of the x (4).

4x = 12.

12 ÷ 4 = 3

x < 3

Answer:

See below

Step-by-step explanation:

1)

7(3 + 5) = 21 + 35.

7 * 3 = 21 to fill the first square, 7 * 5 = 35 to fill the second square.

2)

15 - 10 = x(3 - 2)

Subtract inside parenthesis.

15 - 10 = x(1)

Cancel the 1.

15 - 10 = x

Subtract.

x = 5.

Proof:

15 - 10 = 5(3 - 2)

15 - 10 = 5(1)

15 - 10 = 5

5 = 5.

Step-by-step explanation:

Answer:

infinite number of solutions

Step-by-step explanation:

Given the 2 equations

4x + 6y = 12 → (1)

6x + 9y = 18 → (2)

Equation (2) is a multiple of (1)

Each term has been multiplied by 1.5

Thus the 2 equations are basically the same equation.

This indicates there are infinite solutions to the system

Answer:

3x = 14

Step-by-step explanation:

Add the two equations.

5x + (-2x) = 3x

(-y) + y = 0

6 + 8 = 14

3x = 14.

Step-by-step explanation:

5x - y = 6 and -2x + y = 8

1/ 5x - y = 6

=> y = 5x - 6

2/ -2x + y = 8

Substitute 1/ into 2/ we will have:

-2x + (5x - 6) = 8

=> -2x + 5x - 6 = 8

=> 3x = 14

=> x = [tex]\frac{14}{3}[/tex] <=> y = [tex]\frac{52}{3}[/tex]

- However, the question asked for the final equation when adding 5x - y = 6 and -2x + y = 8 => The correct answer will be: 3x = 14

Answer:

48 boxes

Explanation:

First, find the volume of the rectangular prism (l*w*h) to find out how much it can hold.

15*40*10= 6,000

Then, find the volume of the cubic boxes (l*w*h) to find how much space each of them take up.

5*5*5= 125

Finally, divide the rectangular prism's volume by the boxes' to find out how many can fit inside.

6,000/125= 48 boxes
