Which of these steps will eliminate a variable in this system? 4x-9y=8 2x+3y=24
For eliminate a variables we need addition method or elimination method.
Define the term Variable?In an equation or formula, a variable is a symbol or letter that stands in for an unknowable or varying quantity or value.
We can multiply the second equation by -2, so that the coefficient of x in both equations will be the same but with opposite signs:
⇒ 4x - 9y = 8
⇒ -4x - 6y = -48
Add the two equations together: ⇒ -15y = -40
⇒ y = 8/3
Substitute this value of y back into either equation to solve for x.
⇒ 4x - 9(8/3) = 8
⇒ 4x - 24 = 8
⇒ x = 8
Therefore, the steps to eliminate a variable in this system using the addition method are to multiply the second equation by -2, add the two equations together to eliminate the x variable, solve for y, and then substitute that value back into either equation to solve for x.

write a real-world problem in which two negative integers are subtracted
Problem:
Mary was 12 (-12) feet below sea level, she sawm down another 5 feet (-5). How many feet below sea level is Mary?
(if needed) Answer: -17
The real-world problem in which two negative integers are subtracted is a person diving below the surface of a sea for 60 feet and 50 feet.
-60 - 50 = -110.
110 feet below the surface of the sea.
We have to write a real-world problem in which two negative integers are subtracted.
Let us consider that a person is at the surface of a sea before he dives deep.
The person started to dive below the surface and he was now 60 feet below the surface.
Again he started to dive deep to 50 feet below.
So the person is at how many feet below the surface: - 60 - 50 = -110 feet.
The person is 110 feet below the surface.
And -60 and -50 are the two negative integers subtracted.
Thus,
The real-world problem in which two negative integers are subtracted is a person diving below the surface of a sea for 60 feet and 50 feet.
-60 - 50 = -110.
110 feet below the surface of the sea.

Answer:
y = x +7
Step-by-step explanation:
The slope of the given line can be found as ...
m = (y2 -y1)/(x2 -x1)
m = (3 -7)/(-1 -3) = -4/-4 = 1
Then the point-slope form of the equation for the desired line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)

Hey there!
The given point is (8,-3) as (x1,y1) and slope (m) = -3/4.
Note: use one point formula for finding the equation.
[tex](y - y1) = m(x - x1)[/tex]
Put all values.
[tex](y + 3) = - \frac{ 3}{4} (x - 8)[/tex]
Simplify it.
[tex](y + 3) = - \frac{ 3}{4} x - 8 \times - \frac{3}{4} [/tex]
[tex](y + 3) = - \frac{3}{4} x + 6[/tex]
[tex]y = - \frac{3}{4} x + 6 - 3[/tex]
[tex]y = - \frac{3}{4} x + 3[/tex]
Therefore, the equation is; y = -3/4x+3.
