A=3 so 8*3=24.......................
Step-by-step explanation:
1. 1/4(x + 12)=2 - first isolate X'
- 12 -12
2. 1/4(x) = -10 - 1/4 since its a fraction, you'll have to subtract not divide
-1/4 - 1/4
3. x = -10.25
Andre did the first step correctly, but on the second step he just divided 1.4 by -10, instead of subtract 1/4 from both sides.
Use two points to find the slope
3/4 equals .75, and 60% equals .60. Therefore, we can set up an equation. .75=.60x, where x is the number we are looking for.
Divide each side by .60 to get the variable by itself. .75/.60= 1.25.
Hope this helped!!! :)
Answer:
Q3: x1=2+i, x2=2-i Q4: x1=-3/2+i, x2=-3/2-i
Step-by-step explanation:
( 
± 
) / 
= (
x1= 2+i
x2= 2-i
( 
± 
) / = (-6 ± 
)/4= (-3 ± i)/2
x1 = -3/2 +i
x2 = -3/2 -i
