Answer:
nooo.......how there can only be 20 students.....!
The answer is no!
There can't be 20 students in that class because the ratio is 4:9 so its either 4 boys and 9 girls or 4 girls and 9 boys.This is a total of 13 students because (4+9=13).The answer is That there can not be 20 students in that class because there is only 13 students.
-3x + y = 10
solve the equation for Y
Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-3*x+y-(10)=0
Pull out like factors :
-3x + y - 10 = -1 • (3x - y + 10)

will mark brainliest!!
Answer: -6x
Step-by-step explanation: Since when x is 0, the function's output is 0, the function can only have terms with x in it. You then notice a pattern that x is always being multiplied by -6. You could also use point slope form to solve it, either way you get f(x)=-6x
Answer:
f(x) = -6x
Step-by-step explanation:
The linear equation given in the form of a table is shown as:
[tex]\left[\begin{array}{ccc}x&f(x)\\0&0\\1&-6\\2&-12\\3&-18\end{array}\right][/tex]
Because the equation is linear, in order to find the equation written in slope-intercept form, divide the rise (f(x)) by the run (x):
0 ÷ 0 = 8
-6 ÷ 1 = 8
-12 ÷ 2 = 8
-18 ÷ 3 = 8
Because the quotient for each relation is -6, the linear equation can be written as f(x) = -6x.

Answer:
C. x+8=3x
Step by step explanation:
First, subtract 8 from both sides of the equation
x+8=3x
x+8-8=3x-8
Then, simplify it by subtracting again
x+8-8=3x-8
x=3x-8
Then, subtract 3x from both sides of the equation
x=3x-8
x-3x=3x-8-3x
Then, simplify by combining the terms
x-3x=3x-8-3x
-2x=3x-8-3x
-2x=3x-8-3x
-2x= -8
Then, divide both sides of the equation by the same term
-2x= -8
-2x/-2 = -8/-2
Then, simplify by cancling terms that are in both the numerator and denominator
-2x/-2 = -8/-2
x= -8/-2
Finally, divide the numbers
x= -8/-2
x=4
And that's your answer! :)

Find the slope intercept form of the equation of the line that’s has the given properties (1 , 3) m=1/4
Answer:
y = 1/4x + 11/4
Step-by-step explanation:
Given the slope, m = 1/4, and the point, (1, 3):
We can substitute these values into the slope-intercept form, y = mx + b, in order to solve for the y-intercept.
The y-coordinate (b) of the point, (0, b ) is the y-intercept of the line where the graph of the linear equation crosses the y-axis. The y-intercept is also the value of y when x = 0.
y = mx + b
3 = 1/4(1) + b
3 = 1/4 + b
Subtract 1/4 from both sides:
3 - 1/4 = 1/4 - 1/4 + b
11/4 = b
The y-coordinate, b, of the y-intercept is 11/4.
Therefore, the slope-intercept form is: y = 1/4x + 11/4

It is estimated that each guest at a party will eat 9/10
pounds of chocolates. How many guest can be served with 27 pounds of chocolate?
Answer:
30 guests
Step-by-step explanation:
If each guest eats 9/10 lbs of chocolate, then they eat 0.9 lbs of chocolate. We have 27 lbs of chocolate to be eaten.
To solve this, simply:
[tex]\frac{27}{.9} =30[/tex]
where 27 lbs is divided by 0.9lbs per guest to equal 30 quests.

If someone build a house for 50 years how many months did it take to complete
Answer: 600
Step-by-step explanation: 12 months in one year. 12x50=600 months
Answer:
600 months
Step-by-step explanation:
In 1 year there are 12 months, so we take 50 (the years) and multiply that by 12
50x12=600 and we fact check by 600÷12=50. It takes 600 months to build the house over 50 years.

graphing
both of them please
Step-by-step explanation:
It's easier to graph when both equations are in its slope-intercept form, y = mx + b.
System 1: -3x -15y = 15-2x -10y = 10-2x -10y = 10
-2x + 2x - 10y = 2x + 10
-10y = 2x + 10
-10y/-10 = (2x + 10)/-10
y = -1/5x -1 [slope: -1/5, y-intercept (0, -1)]
-3x -15y = 15
-3x + 3x - 15y = 15
-15y = 3x + 15
-15y/-15 = (3x + 15)/-15
y = -1/5x - 1 [slope: -1/5, y-intercept (0, -1)]
To graph this system, plot the y-intercept, (0, -1) on the graph, then use the slope, m = -1/5 (down 1 unit, run 5 units to the right). Repeat the process until you have enough points to connect and create a line.
Because the given systems of linear equations are equivalent, their lines coincide on top of each other. This means that they have infinitely many points of intersection. Hence, they have infinite solutions.
System 2: 8x + 6y = 244x + 3y = 98x + 6y = 24
6y = -8x + 24
6y/6 = (-8x + 24)/6
y = -4/3x + 4 [slope: -4/3, y-intercept (0, 4)]
4x + 3y = 9
3y = -4x + 9
3y/3 = (-4x + 9)/3
y = -4/3x + 3 [slope: -4/3, y-intercept (0, 3)]
Use the same techniques as described in the first part. Plot the y-intercepts on the graph, then use the slope of each equation to plot other points.
These lines are parallel, which implies that they will never intersect each other. Hence, there's no solution to this system.
Attached are the screenshots of the graphed systems of linear equations.
