What is the answer for -9x plus 1 equals -80?
The 'answer' is the number that 'x' must bein order to make the statement true.-9x + 1 = -80Subtract 1 from each side of the equation:-9x = -81Divide each side by -9 :x = 9
What is the equation inverse of fx equals 5x-1 divided by 9?
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
What is the solution to the equation 27 to the power of 3x plus1 equals 9?
273x+1 = 9 33(3x+1) = 32 9x+3 = 2 9x = 2-3 9x = -1 x = -1/9 Check: 27(3*-1/9)+1 = 9
What us the equation of the following line (19)(00)?
Points: (1, 9) and (0, 0) Slope: 9 Equation: y = 9x
What is the y intercept of the equation y equals 9x?
1. Write the equation in y=mx+b. 2. b is the y-intercept. Ex. 1. y=9x+0 2. b=0. The y-intercept of y=9x is 0. Hint: Since this is a direct variation problem (y=kx), the x-intercept is also 0.

How do you write 12 equals 9x plus 3 in linear equation?
If: 12 = 9x+3 Then: 12-3 = 9x And: 9 = 9x So: x =1
X plus 5 plus 3x - 7 plus 9x plus 3 - 4x?
x + 5 + 3x - 7 + 9x + 3 - 4x Switch the like numbers closer to make the equation easier. x + 3x + 9x - 4x + 5 - 7 + 3 However this is an unsolvable as it isn't an equation. An equation needs an equals sign, for example: x + 3x + 9x - 4x + 5 - 7 + 3 = 0, or x + 3x + 9x - 4x + 5 - 7 + 3 = 10 If it is the former then the answer is 9x = -1 Thus x = -1/9
What is 9x - 4 equals 7x - 6?
This is a linear equation. The value x = -1 is the solution to this equation.
What is the equation inverse of fx equals 5x-1 divided by 9?
If f(x)=(5x-1)/9 Then the inverse is x=(5y-1)/9 9x=5y-1 9x+1=5y (9x+1)/5=y The inverse is f(x)=(9x+1)/5
4 9x -1 9 how do you solve this By the way 4 and 9 are a fraction so is 1 and 9?
4/9x - 1/9 is an expression, not an equation. An expression cannot be solved.
What is the discriminant of the equation 4x2 plus 1 equals 9x-2?
The discriminant is 33.

Which of the ordered pairs satisfy the equation below y -9x?
That will depend entirely on the equation which has not been given.
Does (1, –7) make the equation y = –7x true?
yes
How do you multiply two binomials?
Apply the Distrubutive Property twice as you do when multiplying two-digit numbers Use the FOIL methed First Inner Outter Last. In the equation (3x + 4)(9x + 1) you get. (3x)*(9x) + (3x)*1 + (9x)*4 + 4*1 Now you multiply. 3x*9x = 27x^2 3x*1 + 9x*4 = 3x + 36x = 39x 1*4 = 4 So your entire answer is (3x)*(9x) + (3x)*1 + (9x)*4 + 4*1 = 27x^2 + 39x + 4
