Answer:
Step-by-step explanation:
Solve for x each equation to find the the solution positive or negative.
1) 2x = 6
∴ x = 6/2 = 3 ⇒ positive solution
2) -2x = 6.1
∴ x = 6.1/(-2) = -3.05 ⇒ negative solution
3) 2.9* x= -6.04
∴ x = -6.04/2.9 = -2.08 ⇒ negative solution
4) -2.473 * x=- 6.859
∴ x = ( - 6.859)/( -2.473) = 2.77 ⇒ positive solution

Notes: the rules of positive and negative signs:
The same rules are correct if replaced the division by the multiplication.
Answer:
x = 18
Step-by-step explanation:
(whole secant) x (external part) = (whole secant) x (external part)
(6+x)6 = (8+10)* 8
6*(6+x) = 8(18)
Divide each side by 6
6+x = 8(18)/6
6+x = 8*3
6+x = 24
Subtract 6 from each side
6+x-6 =24-6
x = 18
Answer:
y= -3x+11
Step-by-step explanation:
I am assuming ".1, eight" is (1,8)
y=-3x +10<--- the slope is -3 so plug into this equation: y-y1=m(x-x1)
y-8=-3(x-1)
y-8=-3x+3
Answer: n - 6
Step-by-step explanation:
Multiply -3 and 2.
-3 x 2 = -6
n -6
sorry if this is incorrect
