Answer:
x = 24
Step-by-step explanation:
Step 1:
x/4 - 9 = - 3 Equation
Step 2:
1/4x - 9 = - 3 Turn x/4 into 1/4x
Step 3:
1/4x = 6 Add 9 on both sides
Answer:
x = 24

Answer:
5/8 =x
Step-by-step explanation:
9=8/5(x+5)
Multiply each side by 5
5* 9=5*8/5(x+5)
45 = 8(x+5)
Distribute
45 = 8x+40
Subtract 40 from each side
45-40 = 8x+40-40
5 = 8x
Divide each side by 8
5/8 = 8x/8
5/8 =x
12-13= yx this is that expression
Answer:
8
Step-by-step explanation:
The condition for the discriminant b² - 4ac is
If b² - 4ac > 0 then roots are real, irrational and unequal
If b² - 4ac > 0 and a perfect square, roots are real, rational and unequal.
Thus
b² - 4ac = 8
