Answer:
a. Solution did not change
b. x = 8
Step-by-step explanation:
Solution for the equation is
x−3=5
x = 5 + 3
x = 8
a. Multiply both sides of the equation by a constant, C
C*(x−3) = 5*C
C*x−3*C= 5*C
C*x = 5*C + 3*C
C*x = 8*C
x = 8*C/C
x = 8
b. Multiply both sides of the equation by x
x*(x−3) = 5*x
x^2−3*x= 5*x
x^2 = 5*x + 3*x
x^2 = 8*x
x^2/x = 8
x = 8
Answer:
9 hours
Step-by-step explanation:
You have to add both hours to get the total amount. So 3+6=9
L is the closest to -12.6. It's obvious to see that every unit (1) on the number line is divided into five segments, so that each small segment represents 1/5=0.2. We know that -12.6 is between -12 and -13. -12.6 is 0.6 farther to the left than -12 (since -12.6 more negative), so we count 0.6/0.2=3 segments to the left of -12, corresponding to point L on the number line.
Hello :
<span>-3 = x² + 4x+ 1
x²+4x+4=0
a=1 and b= 4 c= 4
</span><span>b^2 - 4ac = (4)²-4(1)(4) =0
one solution : -b/2a = -4/2 = -2
note : </span>x²+4x+4=0
(x+2)² = 0
x+2 = 0
x= -2
