To find the amount he spent in total on movies we need to do $68.27-$52.35=$15.92
Now to find the amount of movies we need to do $15.92/$1.99=8 movies
Hello :
<span>Cos θ = -3/5
sin</span>θ = - 4/5
because : Cos² θ +sin²θ = (-3/5)²+(-4/5)2 =9/25+16/25 = 25/25 = 1
and θ is in QIII.where : sinθ <span>< 0</span>
Answer:
G(-6) = -29
Step-by-step explanation:
plug -6 into the equation
G(-6) = 5(-6) +1
multiply
G(-6) = -30+1
add
G(-6) = -29
My work and the answer is shown up in the picture.
I used the substitution method to check my answers by using x and y into the two equations.
Answer:
(-2, -16)
Step-by-step explanation:
the minimum is at the vertex which can be found using -b/2a for the x-value of the vertex.
y = 3x^2 + 12x - 4
= ax^2 + bx - c
b = 12, a = 3
-12/(2(3))
-12/6
x = -2
y = 3(-2)^2 + 12(-2) - 4
y = -16
(-2, -16)
