(x + 7)/-3 = 2
Multiply by -3
(x+7) = -6
Subtract 7
x = -13
The number is -13
Answer:
Theta=60
Step-by-step explanation:
Lets start to get the value of x in
Just do the opposite which is
So
Still we got only the value of x not theta then
The value of x = theta/2
Theta/2=30 multiply each side by 2
Theta = 60
Answer:
x=-7 x=4
Step-by-step explanation:
(x −2)(x + 5) = 18
Foil
x^2 +5x-2x-10 = 18
Combine like terms
x^2 +3x -10 =18
Subtract 18 from each side
x^2 +3x -28 = 0
Factor
What two numbers multiply to -28 and add to 3: 7 and -4
(x+7) (x-4) =0
Using the zero product property
x+7=0 x-4 =0
x=-7 x=4
Hello friend!
1/3(9x+12)=15
We move all terms to the left:
1/3(9x+12)-(15)=0
Domain of the equation: 3(9x+12)!=0
x∈R
We multiply all the terms by the denominator
-15*3(9x+12)+1=0
multiply elements
-45x(9+1=0
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
