2x-438 = -438+2x= 2(x-219)
Answer:
150cm
Step-by-step explanation:
0.4*100-5=35
(35+40)*2=150
X=1 and y=-2
In ordered pairs it would be (1,0) and (0,-2)
Answer:
x<2 and x> -8
Step-by-step explanation:
<span><span>y = 2 + 2sec(2x)
The upper part of the range will be when the secant has the smallest
positive value up to infinity.
The smallest positive value of the secant is 1
So the minimum of the upper part of the range of
y = 2 + 2sec(2x) is 2 + 2(1) = 2 + 2 = 4
So the upper part of the range is [4, )
The lower part of the range will be from negative infinity
up to when the secant has the largest negative value.
The largest negative value of the secant is -1
So the maximum of the lower part of the range of
y = 2 + 2sec(2x) is 2 + 2(-1) = 2 - 2 = 0
So the lower part of the range is (, 0].
Therefore the range is (, 0] U [4, )
