write the equation of the line passes through the given points (0,-2) and (-9,-7)
what is the equation?
Answer:
[tex]y= \frac{5}{9}x - 2[/tex]
Step-by-step explanation:
Let's write the equation in the slope-intercept form! In the slope-intercept form, y= mx +c, m is the slope and c is the y-intercept.
[tex]\textcolor{blueviolet}{\text{\textcircled{1} Find \: the \: slope}}[/tex]
[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]
where (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate
Slope
[tex] = \frac{ - 2 - ( - 7)}{0 - ( - 9)} [/tex]
[tex] = \frac{ - 2 + 7}{0 + 9} [/tex]
[tex] = \frac{5}{9} [/tex]
[tex]\textcolor{blueviolet}{\text{\textcircled{2} Substitute \: value \: of \: slope}}[/tex]
[tex]y = \frac{5}{9} x + c[/tex]
[tex]\textcolor{blueviolet}{\text{\textcircled{3} Substitute \: a \: pair \: of \: coordinates}}[/tex]
When x= 0, y= -2,
[tex] - 2 = \frac{5}{9} (0) + c[/tex]
c= -2
[tex]\textcolor{blueviolet}{\text{\textcircled{4} Substitute \: value \: of \: c}}[/tex]
[tex]\bf y= \frac{5}{9}x - 2[/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?
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

x + 17 = -2x + 23
what is the answer to this ? and show me the work please
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
a room is 400 inches long and 300 inches wide. if the length is shortened to 10 inches how wide is the room
Answer:
Step-by-step explanation:
The room's width should remain unchanged at 300 inches.
If the question is asking room of the same area but length shortened to 10 inches, then the answer is 400*300/`10 = 12000 inches.
One thing the question lacking (The area of both room is same).

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.
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

* A turtle and a snail start moving towards each other when they are 200 feet apart. The turtle is running at a speed of T feet per minute, and the snail is moving at a speed of S feet per minute. How soon will they meet?
Answer:
Step-by-step explanation:
since you gave no values for both T and S, this is impossible to solve.
figure out what the difference is between the 2 numbers of T and S, then divide that by 200. that should give you the answer.

9g − g + 4g − 8g − 2 = 18
plz
Answer:
g = 5
Step-by-step explanation:
Combine like terms on the left side.
9g - g + 4g -8g = 4g
4g - 2 = 18
Add 2 to both sides.
4g = 20
Divide both sides by 4.
g = 5

Find the Pattern
12 ↦ −1
3 ↦ −4
0 ↦ −5
−1 ↦ −5.3…
−9 ↦ −8
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?
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?
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
