What is y equals x plus 2 when x equals -1 and y equals 5?
If [ y = x + 2 ], then x is not -1 when y = 5.
If [ y = x + 2 ],
then when x = -1, y = 1,
and when y = 5, x = 3.
Using substition what is the answer to y equals 3x plus 11 y equals -2x plus 1?

How do you solve the problem x plus one third equals 144?
x + 1/3 = 144
solve for x
x = 144-1/3
change the fraction to a decimal
x = 144-0.333
x= 143.667
How do you Solve for n n4 equals 12?
Step 1: 4n=12
Step 2: divide both sides by 4
Step 3: 4n/4 = 12/4
Step 4: reduce
Step 5: n=12/4
Step 6: n=3
What is the minimum and maximum points of y equals x2-4x plus 5 all over x-2?
(x-2) is not a factor of the numerator and so y tends to minus infinity as x approaches 2 from below. As x approaches 2 from above, y tends to plus infinity. There are, therefore, no maximum or minimum values for y.
What is the solution to -7t equals 42?
-7t = 42
Multiply each side by -1:
7t = -42
Divide each side by 7:
t = -6
Why is the line of y equals 5 is a horitzontal line?
Because the only Y value that a point on the line can have is 5. and if you can only have points with a Y value of 5 you will have a line that runs straight on the 5th step of your graph.
A function has an input and an ouput. Each input can only have one output.
Examples of functions:
x = y
y = x2
y = cos(x)
where y is the output and x is the input.
How do you solve 6a equals 0.24?
You need to isolate a. To do this, divide both sides by six, and you're left with a=0.04.
How many 4 inch tile to cover 10 X 10 area?
If it is a 4inch by 4inch (1/3foot by 1/3foot)tile and it covers a 10ft by 10ft area then it will take 900 of these tiles to cover the whole floor.
If you walk ten feet on a edge of this floor then you will have to place 30 tiles along this edge. Since the area is a square area then to find the amount of tiles just multiply 30 by 30 to get 900tiles.

How do you find an angle of a right angled triangle if you know 2 sides?
You use the Pythagorean theorem, which can only be applied to right triangles:
a2+b2=c2, where a and b are the triangle's legs and c is the triangle's hypotenuse.
Plug the two sides you know into the equation, then solve for the unknown side.
