Factors of 4: 2 and 2
y= (x+2)²
+√y or -√y = x+2
x= 2+√y , 2-√y
interchange variables
y= 2+√x , 2-√x
f ⁻¹(x) = 2 + √x, 2 - √x
I'm pretty sure it is only b because <span>when you subtract two rational numbers, you always get back a rational number.</span>
Answer:
Step-by-step explanation:
Answer:
Step-by-step explanation:
E is the midpoint of Ac & D is the midpoint of AB
DE = (1/2)BC {Midpoint theorem}

2*x + 2*1 = 4x - 6
2x + 2 = 4x - 6
Add 6 to both sides
2x + 2 + 6 = 4x
2x + 8 = 4x
Subtract 2x from both sides
8 = 4x - 2x
2x = 8
Divide both sides by 2
x = 8/2
x = 4
Answer:
8.5 min
Step-by-step explanation:
Here, distance = rate times time. The rate is 10 in/min, and so
d = (10 in/min)t.
If the snail travels 85 in, then 85 in = (10 in/min)t, and we solve for t as follows:
t = (85 in) / (10 in/min) = 8.5 min
