X/4 is the same as 1/4x, so you have the equation 1/4x + 7 = 5. subtract 7 to both sides to get the equation 1/4x = -2. then you multiply by four (which is the same as dividing by 1/4) to get x = -8
Answer:
see explanation
Step-by-step explanation:
the domain is the set of x- coordinates from the ordered pairs , that is
domain : { - 7, - 3, 0, 5 }
the range is the set of y- coordinates from the ordered pairs, that is
range : { - 2, 1, 2, 5 }
Answer:
x=-2,-4 is your answer
x²+6x+8=0
doing middle term factorization
x²+4x+2x+8=0
x(x+4)+2(x+4)=0
(x+4)(x+2)=0
either
x=-4
or
x=-2
