B would have to equal 9 and a should equal -2 to get 0
Answer:
ΔGFE≈ΔJKL
Step-by-step explanation:
Keeping in mind that, there are 12 months in a year, therefore, 7 months is really just 7/12 of a year.
Answer:
x=√139-3, x=-√139-3
Step-by-step explanation:
to complete the square, you first move the constant to the other side of the equation-its already done for you!
now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.
What you do to one side has to be done with the other.
x^2+6x+9=130+9
now you can factor the square:
(x+3)^2=139
squareroot both sides:
x+3=√139
x+3=-√139
now subtract both sides by 3
x=√139-3
x=-√139-3
f(x) = -x + 2
f(-1) This means that they want you to find the value of f(x) or y when x = -1.
f(x) = -x + 2 Substitute/plug in -1 into "x" since x = -1
f(-1) = -(-1) + 2 (two negative signs cancel each other out and become positive)
f(-1) = 1 + 2
f(-1) = 3
