Answer:
-1
Step-by-step explanation:
I like the coefienti in front of 2nd degree to be positive
times -1
x^2-4x=-x+4
add x to both sides and minus 4 from both sides
x^2-3x-4=0
factor
what 2 numbers multiply to get -4 and add to get -3?
-4 and 1
(x-4)(x+1)=0
set to zero
x-4=0
x=4
x+1=0
x=-1
-1 and 4

Answer:
2000×0.004=8
Step-by-step explanation:
Isolate the variable by dividing each side edit its factors that don't contain the variable
Y = 4x - 3
y = -x - 13
Since both equations equal y, we will just substitute both equations to equal each other.
4x - 3 = -x - 13
+x on both sides
5x - 3 = -13
+3 on both sides
5x = -10
/5 on both sides
x = -2
Substitute x = -2 into one of the equations.
y = -x - 13
y = -(-2) - 13
y = 2 - 13
y = -11
To check answer, plug in both x and y values into one of the equations.
y = -x -13
-11 = -(-2) - 13
-11 = 2 - 13
-11 = -11
Answer:
x = -2
y = -11
