Answer:
10
Step-by-step explanation:
Use PEMDAS to rewrite the equation as:
m - (2 * n) + 2 =
16 - (2 * 4) + 2 =
16 - 8 + 2 =
10
Hey there!
(9) 2x-9y=45
... -9y=-2x+45
... y = (2/9)x - 5
Slope = 2/9
y-intercept = (0,-5)
(11) 3y+2x=-15
... 3y=-2x-15
... y = (-2/3)x - 5
Slope = -2/3
y-intercept = (0,-5)
(12) 10x+8y=40
... 8y=-10x+40
... y=(-10/8)x+5
Slope = -5/4 (after simplifying )
y-intercept = (0,5)
Hope my answer helps!
Straight line = 180, so 180-100=80, a triangle = 180, x equals to 180-(70+80) =30, the answer is a
Answer:
a) f(6)=(6)^2+4(6)+1=65
b)f (x+9)=(x+9)^2+4 (x+9)+1=(x^2+18x+81)+(4x+36)+1=x^2+22x+117
f (-x)=(-x)^2-4x+1
