w = 70.25
y = 2 (Divide each side of the equation by -45)
Adding a negative number to a negative number makes a larger negative. In order to solve this you add the numbers together as a positive then add a negative sign.
Your question is not very clear. Are you asking: solve for x where negative 4 over x equals negative 20. x equals 1/5 (one fifth)
-5x2 = -75 x2 = 25 x = ±sqrt( 25 ) x = ±___
A number to a negative power is equal to One divided by number to its positive power. So, x^-2 is equal to 1/x2.
Question 3C: Four minus seven equals negative two.
34 = 81 so x is 4
By elimination: x = 3 and y = 0
b = 14
x2=-81take the square root of both sidessince 81 is negative you need to take 81 times i when i=-1 then solve as the square root of 81. your answer is x=9i
Depends on the voltage. R equals V2/P . Or the current: R equals P/I2 .
First, solve for y.y=-8xif x=2, then y=-16.
1 over 5^2. which is 1/25
x=2 because 9-(14)=-5
Multiply or divide both sides by -1. -b = 12.5 b = -12.5
-3x + 5 = 20 -3x = 15 x = -5
x + 1= -y implies x - y = 1
Better formatting is cos(2x+20)=-0.5
3^(-4) = (1/3)^4 = 1/81
Yes but not me
-x = 1/2Multiply each side by -1 :x = -1/2
