Is y equals -3x plus 3 and 4y plus x equals -1 perpendicular lines?
No because the slope of the second equation is 1/4 and for it to be perpendicular to the first equation it should be 1/3
How can the factoring of the first equation help you factor the second equation 9x2 power 18x plus 8 9a2power 18ab plus 8b2power?
The first equation factors to (3x + 2)(3x + 4) The second equation factors to (3a + 2b)(3a + 4b)
If 2x2 plus 5x-12(2x-3)(x plus 4) which equations should be solved to find the roots of 2x2 plus 5x-120?
To find the roots of the equation (2x^2 + 5x - 120 = 0), you first need to set the equation equal to zero. This can be done by solving the quadratic equation directly. Alternatively, you could factor it if possible or use the quadratic formula (x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}), where (a = 2), (b = 5), and (c = -120).
Is the equation C3H6 plus O2 yields CO2 plus H20 balanced?
No, the balanced equation is 6Ca + 3O2 ---> 6CaO. The product, calcium oxide, is CaO and not CaO2.

-1
What kind of equation is r2 equals x2 plus y2 plus z2?
A Diophantine Equation. In order to solve it, you should use Euclide's algorithm.
Why is an equation written in the form Ax plus By equals c called a linear equation?
The equation contains variables which are only raised to the first power.
What steps should be used to graph the equation y 4 (x 2)?
The first steps are to include an equality sign and plus or minus symbols in the given question because without them the question can't be considered to be an equation.
What is the first step in solving the equation 7q plus 9 equals 3?
the first step in solving the equation is to subtract the nine from the three. you will get negative 6.
What is wrong with this word equation calcium chloride plus magnesium sulfate barium chloride plus magnesium sulfate?
This word equation is incorrect because it does not follow the law of conservation of mass. The equation should be: calcium chloride plus magnesium sulfate yields barium sulfate plus magnesium chloride.
What is the solution of y equals x plus 2 and negative 5x plus 6y equals 15?
y=x+2 -5x+6y=15 You use the substitution property to plug y into the 2nd equation -5x+6(x+2)=15 Then, you solve the equation That should leave you with x=3 Then you plug that into the first equation, and that should leave you with a final answer of x=3 and y=5
