Step-by-step explanation:
Solve the inequality for b
-15b <= 45 divide both sides by -15, since you're dividing by a negative number switch the direction of the sign.
b >= -3
So, your number line is all values of b greater than or equal to -3. Since it is including -3, the circle will be filled and increase to the positive.
f(x) = 4x + 4 means that if we put an x into our function, a 3x + 4 come out.
So in this problem, we're putting a 2 into our function which
means that a 3(2) + 1 comes out which simplifies to 6 + 1 or 7.
So f(2) = 7 or the value of the function at 2 equals 7.
Answer:
P≈28.28cm
d = Diagonal 10cm
Using the formulas
P=4a
d=2a
Solving for P
P=22d=2·2·10≈28.28427cm
