The area of a triangle is:
A=hb/2 where h=height and b=base
We can let the "height" be the horizontal magnitude, (x3-x1)
And the base would then be the vertical magnitude, (y2-y1)
So the area is:
A=(1/2)(y2-y1)(x3-x1)
Part A
t = 1
order pair (1 , 1,200)
t = 2
order pair (2 , 2,400)
part B
p = 1,200t
Answer:
x = -9±√145 (= 3.04 or -21.04)
Step-by-step explanation:
x²+18x-64 = 0 (move the constant to the right side, add 64 to both sides)
x²+18x = 64 (divide the x-term by 2, square it, then add it to both sides)
x²+18x + (18/2)²= 64 + (18/2)² (simplify)
x²+18x + 9²= 64 + 9²
x²+18x + 9²= 64 + 81
x²+18x + 9²= 145 (simplify left side using the property (a+b)² = a²+ 2ab+b²)
(x+9)² = 145 (take square root of both sides)
x+9 = ±√145
x = -9±√145 (= 3.04 or -21.04)
Answer:
x=2
Step-by-step explanation:
5x+10=24-2x
5x+10-10=24-2x-10
5x= -2x+14
5x+2x= -2x+14+2x
7x=14
7x/7=14/7
x=2
Answer:
8x2=16+f=17
Step-by-step explanation:
4e become 4x.
both exe =8
f is by itself so you divide=1
so 8x2=16and you add f
