5x - 4y = 40
x intercept is when y = 0
5x - 4*0 = 40
5x = 40
x = 40/5
x = 8 x intercept = 8
y intercept is when x = 0
5*0 - 4y = 40
-4y = 40
y = 40/-4
y = -10
y intercept = -10
x intercept = 8, <span>y intercept = -10</span>
Answer:
x = -3
Step-by-step explanation:
You will have to distribute first
7 -2x -11 + 9 -3x = 20
Then, combine you like terms
-2x -3x = -5x
7 -11 +9 =5
Then you write it as an equation
-5x +5 = 20
Next you will want to have x by itself which means you have to get rid of the 5 by substracting 5 on each side (opposite of addition is substraction)
-5x = 15
Then you divide each side by -5 ( opposite of multiplication is division)
x= -3
Hope this helped :D
Answer:
+7 or 7
Step-by-step explanation:
an integer is a whole number. So the question asks what whole number represent this real world situation. A positive charge to an atom can not be represent by a negative number (number below zero). Therefore, it has to be positive.
Thank you for your question!
Your really close!
Just set this up as an algebraic equation:
4x - 10 = 30
4x = 40
x = 10
Hope this helped!
