X^2 + 4x -12 = (x+6)(x-2)
so
(x+6)(x-2)
---------------- = x - 2
x + 6
f(x) = x -2
because
if x = -6
then y = -6 - 2 = -8
(-6,-8) is the order pair
Answer:b
Step-by-step explanation:
Answer:
15foot
Step-by-step explanation:
The set up will give a right angled triangle.
The length of the shadow will be the hypotenuse = 16foot
The height of the tree will be the opposite = x
The angle of elevation = 70°
Using the SOH CAH TOA trig identity
Sin theta = opposite/hypotenuse
Sin 70 = x/16
x=16sin70
x = 15.04feet
Hence the height of the tree to the nearest whole foot is 15foot
all the angles add up to 360 using the equation 180(s - 2)=d
d is the degree and s is the number of sides. it is an iscocles triangle so if you mirror the angles are the same
75+75=150
360-150=210
there are two angles left so divide by two
210/2=105
x and y equal 105
