Division is multiplication by a fraction
54/3=(3*18)/3=18
105/7=(7*15)/7=15
Answer:
5x + 3y = -6
2x + y = -4.
Step-by-step explanation:
Answer: slope (m) = -2
Step-by-step explanation:
y-3=-2(x+5)
put it into y=mx+b
use PEMDAS-Parantheses, Exponents, Mult. Div. Add. Sub. for your order of operations.
first, parantheses.
-2(x+5)
-2 times x = -2x
-2 times 5 = -10
your new equation is y-3 = -2x-10
now, to get y by itself, cancel out the -3 by adding a positive 3 to both sides.
you final equation will be y=-2x-7
in the form y=mx+b, m is your slope.
therefore, -2 is your answer, or slope.
Answer:
A. f(x) = -0.5(x+3) (x-5)
