X=0.6
32-6x=30-3x
32-6x+3x=30
-6x+3x=30-32
-3x=30-32
-3x=-2
X=2/3
X=0.6

y=-2x+4
y=-8x-6
y=3x+5
y=x-10
y=4x-4
Step-by-step explanation:
these questions require a series of equations in order to solve but if you are asking for them to be rearranged
If there is only one solution, at x=-3, then the factor of (x+3) must be repeated. The equation must be equivalent to
... (x +3)² = 0
This multiplies out to give
... x² +6x +9 = 0
The value of m is 6.

For finding the square of a binomial, you can either use the special form you have memorized:
... (x +a)² + x² +2ax + a²
or you can use the distributive property.
... (x +a)² = x(x +a) +a(x +a)
... = x² +ax +ax +a² = x² +2ax +a²
3 cases / 4 weeks = 0.75 cases per week
for 13 weeks = (0.75 * 13) = 9.75 cases
9.75 - 5 = 4.75 rounded = 5...he needs to order 5 cases
