Answer:
f the equation is in the form, ax + b = c, where x is the variable, you can solve the equation as before. First “undo” the addition and subtraction, and then “undo” the multiplication and division. Solve 3y + 2 = 11. Subtract 2 from both sides of the equation to get the term with the variable by itself.
Step-by-step explanation:
In order to be a function we need one x-value corresponding to one y-value which is shown in the table. if we can have the same x value corresponding to multiple y values then it is no longer a function it is a relation.
Step-by-step explanation:
x²+2x-3=0
(x²+3x)-(x-3)=0
x(x+3)-1(x+3)=0
(x-1)(x+3)=0
x=1 or x=-3
A rhombus is a square when the angles are at 90°.
Answer:
x = 29
Step-by-step explanation:
the angle will have to equal 90 degrees so (3x+3) = 90
90-3 = 87
87/3 = 29
