This one is B. the y=>2 leaves A and B the X=>-4 eliminates A. that leaves B
X²=12x-5
minus 12x both sides
x²-12x=-5
take 1/2 of the linear confident and square it
-12/2=-6, (-6)²=36
add that to both sides
x²-12x+36=-5+36
factor perfect square
(x-6)²=31
sqrt both sides, remember to take positive and negative roots
x-6=+/-√31
x=6+/-√31
the solutions are 6+√31 and 6-√31
Answer:
x^1
Step-by-step explanation:
if you divide exponents with the same coefficients, you subtract the two exponents
Im pretty sure it would be 54÷ b- 6 if your looking for only the cost of the braclets nothing else.
Answer:
Distributive Property
Step-by-step explanation:
They distributed the -3 to x and 4. In this case, to distribute the -3, you multiply it to each term.
-3 × x = -3x.
-3 × 4 = -12.
-3x - 12
