Simplifying
3x + 3y = -3
Solving
3x + 3y = -3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3y' to each side of the equation.
3x + 3y + -3y = -3 + -3y
Combine like terms: 3y + -3y = 0
3x + 0 = -3 + -3y
3x = -3 + -3y
Divide each side by '3'.
x = -1 + -1y
Simplifying
x = -1 + -1y
Take out the highest common factor.
The highest common factor between 6 (which 2*3) and 14 (which 2*7) is 2
The highest common factor between x^2 (which is x * x) and x(which is x) is x.
2x(3x - 7) = 0
Now either 2x = 0 in which case x = 0
or
3x - 7 = 0
3x = 7
x = 7/3
The graph below shows you the answers to where 6x^2 - 14x cuts the x axis is below.
Rotational symmetry means it can be rotated around the center and still be the same
example: the letter O
for reflection symmetry, it has 1 line of reflection and can be reflected across that line and map on itself
example: U
so the one in the middle is the one with both symmetries
alright, so the letters A,B,C,D,E,K,M,T,U,V,W,Y go in the left circle
the letters N,S,Z go on the right most circle
and the letters H,I,O,X go in the intersection
the rest of the letters are outside
Hi there! :)
Answer:
We can disregard the units temporarily to create a ratio for 4.5 to 4:
4.5 is not a whole number- we can convert this number in the ratio to a whole number by multiplying both numbers by 2:
2 · (4.5 : 4) = 9 : 8
Express as a fraction:
