Find the Pattern

I have to find a formula to get from the left number to the right number, but I cannot find the pattern. How do I do this, and what is the solution?
Answers
Answer: y = (1/3)x - 5
This is the same as writing [tex]y = \frac{1}{3}x-5[/tex]
======================================================
Explanation:
Assume we have a linear pattern matching the form y = mx+b.
The first row has x = 12 lead to y = -1
The second row has x = 3 lead to y = -4
This produces the two points (12,-1) and (3,-4)
Let's find the slope through those points.
m = (y2-y1)/(x2-x1)
m = (-4-(-1))/(3-12)
m = (-4+1)/(3-12)
m = -3/(-9)
m = 1/3
The slope is 1/3.
The y intercept is b = -5 since x = 0 leads to y = -5
We go from y = mx+b to y = (1/3)x - 5
--------------------------
To verify we have the correct equation, plug in each left side value as x values.
Let's try x = 12
y = (1/3)x - 5
y = (1/3)*12 - 5
y = 4 - 5
y = -1
This shows that the input x = 12 maps to the output y = -1
i.e. 12 ↦ −1 is the case here.
Repeat for x = 3
y = (1/3)x - 5
y = (1/3)*3 - 5
y = 1 - 5
y = -4
We can see that 3 ↦ −4 occurs.
I'll let you check the others, but you should find that the other mappings hold true as well. Therefore, the answer has been fully confirmed.

Un grupo de 25 estudiantes aportará $4.00 cada uno, para comprar una pizarra.
Si se reduce la cantidad de estudiantes a 20, ¿cuál será el aporte de cada
estudiante para comprar la pizarra?
Answers
Usando algebra, veremos que cada estudiante debe aportar $5.00.
¿Cuál será el aporte de cada estudiante?
En el caso en el que hay 25 estudiantes, cada uno aporta $4.00, entonces la cantidad total que se colecta es:
25*$4.00 = $100
Ahora, en el caso de que hay 20 estudiantes, cada uno aportara una cantidad x, de tal forma que:
20*x = $100
Debemos resolver la ecuación de arriba para x:
x = $100/20 = $5.00
Es decir cada estudiante debe aportar $5.00

A group of friends are having a 400 m race julze can run 25 meters in 4 seconds alex can run 60 meters in 10 seconds jaheim can run 6.5 meters Yuseph can run 100 meters in 15 seconds if each of them could keep their constant speed who would win the race explain your answer.
Answers
Answer:
Yuseph would win the race because he has the highest speed and will run 400m in 60 seconds
Step-by-step explanation:
Race = 400m
julze can run 25 meters in 4 seconds
= 400m / 25m × 4 seconds
= 16 × 4
= 64 seconds
alex can run 60 meters in 10 seconds
= 400m / 60m × 10 seconds
= 6.67 × 10
= 66.7 seconds
Yuseph can run 100 meters in 15 seconds
= 400/100 × 15 seconds
= 4 × 15
= 60 seconds
jaheim can run 6.5 meters
Yuseph would win the race because he has the highest speed and will run 400m in 60 seconds

Answers
Answer:
2
Step-by-step explanation:
[tex]x + 17 = - 2x + 23 \\ \\ x + 2x = 23 - 17 \\ \\ 3x = 6 \\ \\ x = \frac{6}{3} \\ \\ x = 2[/tex]
Answer:
x = 2
Step-by-step explanation:
First, we will move all the xs to one side and everything else to the other side.
x + 17 = -2x + 23
+2x +2x
-17 -17
This gives us:
x + 2x = 23-17
Then we can just combine like terms:
3x = 6
And divide both sides by three:
x = 2
If a chemical costs $3.54 for 20 ounces, what is the cost of 25 gallons of the chemical?
Answers
there are 128 fluid ounces in 1 gallon, that means that 25 gallons is 25 * 128 = 3200 ounces.
so if we know that for 20 ounces is 3.54, how much will it be for 3200 ounces?
[tex]\begin{array}{ccll} \$ & oz\\ \cline{1-2} 3.54 & 20\\ x& 3200 \end{array} \implies \cfrac{3.54}{x}=\cfrac{20}{3200}\implies \cfrac{3.54}{x}=\cfrac{1}{160}\implies 566.4=x[/tex]
An alloy is composed of nickel, zinc, and copper in a 5:4:8 ratio. How many kilograms of each metal is needed to make 3.4 kg of this alloy?
Answers
Answer:
1 kg, 0.8 kg, 1.6 kg
Step-by-step explanation:
Add up each part in the ratio
5 + 4 + 8 = 17
Divide the mass of the alloy by 17
3.4/17 = 0.2
To find out how much of each metal is in the alloy multiply 0.2kg by how many parts of it are in the alloy.
Nickel - 5 parts
0.2 x 5 = 1 kg
Zinc - 4 parts
0.2 x 4 = 0.8 kg
Copper - 8 parts
0.2 x 8 = 1.6 kg
Answer:
Step-by-step explanation:
5x+4x+8x=3.4
17x=3.4
x=0.2
Nickel 1 kg
Zinc 0.8 kg
Copper 1.6 kg
