Answer:
-25/9
Step-by-step explanation:
-5/6 : 3/10
-->(cross multibly)
=-5 *10 : 6*3
=-50/ 18
=-25/9
X2 - 16, is the answer. The first one.
x^2 - 16 = (x)^2 - 4^2, difference of two squares :)
<span>2x^2 - 2x - 1 = 0 a = 2, b = -2, c = -1 b^2 - 4ac = (-2)^2 - 4(2)(-1) = 4 + 8 = 12
so the answer is 12

Answer: The answer would be x < 10/7
Step-by-step explanation:
Rearrange:
Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :
7*x (10)>0
Step by step solution :
STEP
1
:
Pulling out like terms
1.1 Pull out like factors :
7x - 10 = -1 • (7x + 10)
Equation at the end of step
1
:
STEP 2
:
2.1 Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
7x+10 < 0
2.2 Divide both sides by 7
x+(10/7) < 0
Solve Basic Inequality :
2.3 Subtract 10/7 from both sides
x < 10/7
