Find the interval on the real number line for which the radicand is nonnegative (greater than or equal to zero)</span><span> so that the radical sqrt(8 x - 8) defines a real number. Leave answer in interval notation.
</span>
sqrt(8 x - 8) is definite function if <span>8 x - 8 ≥0, </span>
8 x <span><span> ≥ 8</span> and x </span>≥ 8/ 8 = 1, x <span>≥ 1, so the interval solution is [1, infinity[</span>

14.50 × 7%
= 1.015
= 14.50 + 1.015
= 15.515

Solve using system of equations.
y=total money spent, x=amount of rides
y=12+3.5x
y=33
Solve! Set them equal to each other
12+3.5x=33
-12 -12
3.5x=21
x=6
After six rides the all day pass would be cheaper. ;)
Answer:
Town B will eventually overtake Town A
in 1990 Town B will have a larger population
Step-by-step explanation:
To work out how big town A will be in 1990 you need to do 200 + (200x40) because you add 40 years worth of increased population onto the starting population
To work out how big town B will be in 1990 you need to use the equation 200 X 1.1^40 because to work out plus 10 percent you need to do 1.1 and do it to the power of 40 for how many years
in 1990 town a will have a population of 8200 and town B will have a population of 9051.85
Answer: 20/3
Solution:
-5^2/-15 + 5
Determine the sign
5^2/15 + 5
Calculate
25/15 + 5
Simplify
5/3 + 5
Transform the expression
5 + 15/3
Calculate
= 20/3
(But there’s alternative forms too!: 6.6, 6 2/3)
