Write the equation of the line that passes
through the points (3, 1) and (9,-3)
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
Jamal launched a website for his custom shoe store. On the first day, 3 visitors registered on the website. 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, how many visitors will he predict to register on the fifth day.
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:
[tex]2x^2+x+7y[/tex]
Step-by-step explanation:
We are given the equation [tex]2(x^2+3y)+x+y[/tex] and are asked to simplify it.
To do so, we need to first get rid of the parenthesis, since x² and 3y aren't like terms, it isn't solvable unless we try another way, which is the distributive property.
2 is next to the parenthesis, in the distributive property, we would multiply the number outside of the parenthesis with all the numbers inside the parenthesis. Therefore :
[tex](2*x^2) + (2*3y) + x +y[/tex]
[tex]2x^2 +6y+x+y[/tex]
Now that we have like terms, we can add them together :
[tex]2x^2 + 6y+x+y[/tex]
[tex]2x^2 + x+7y[/tex]
Answer:
Hello! Your answer would be, 2[tex]x^{2}[/tex] + [tex]x[/tex] [tex]7y[/tex]

[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:
[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

Substitution method please help :3
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
You own a truck that has a trailer in the shape of a rectangular prism. It has a height of 15 m and a length of 40 m, and a width of 10 m. If you wish to fill this trailer with 5m x 5m x 5m cubic boxes, how many boxes will fit into the trailer?
48 boxes
600 boxes
1,200 boxes
240 boxes
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

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
How many solutions for the system of equations 4x + 6y = 12,6x +9y = 18
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

Carla wants the total weight of the bags to be four pounds. If she can only pick one more bag, which bag weight should she pick? pound
Answer:
1/8
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.
Need help in math i got 40 points
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.
−9x (5x+4 ) +10 (x+3) can someone please solve his for me thank u step by step please i really need to find out how to do it
Answer:
-45[tex]x^{2}[/tex]-26x+30
Step-by-step explanation:
So first you let's divide this equation into three parts.
Part one -9x(5x+4)
Step one: you have to distribute the -9x to the numbers in the parentheses. That would leave us with a -9x*5x = -45[tex]x^{2}[/tex] and -9x*4 = -36xStep two: Put the answers together. That would leave us with -45[tex]x^{2}[/tex]-36x.Part two 10(x+3)
Step one: you have to distribute the 10 to the numbers in the parentheses. That would leave us with a 10*x = 10x and 10*3 = 30Step two: Put the answers together. That would leave us with 10x+30Part three solve
Step one: combine and put together what you have solved for. That would leave us with a -45[tex]x^{2}[/tex]-36x+ 10x+30 Step two: combine like terms. The like terms here are -36x and 10x. When you combine them you would get -26x.Step three: Write the equation in standard form. Therefore the answer is -45[tex]x^{2}[/tex]-26x+30.Let me know if anything is confusing!
