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>

Answer:
y=12x+22 is linear but not proportional
Step-by-step explanation:
This is a linear equation because it has an x and y within the expression without exponents or other complex operators. We can rearrange and simplify the equation into slope-intercept form.
This linear equation follows the form y=mx+b where m is the slope and b is the y-intercept. For this function, m=12 and b=22. This is not a proportional relationship because the function's y-intercept is something other than 0.
2 hours is the correct answer I believe

Answer:
12
Step-by-step explanation:
The ratio of cars to trucks to motorcycles is $4:3:2.
If there are $42$ cars and trucks total,
To get how many motorcycles are there
Sum up the ratio of cars and trucks 4:3= 4+3 = 7
Sum up the ratio of cars and trucks and motorcycles
4+3+2 =9
Let the total number of cars and trucks and motorcycles be represented as A
The total number of cars and trucks in the question is 42
(7/9) x A = 42
7A/9 = 42
cross multiply
7A = 42×9 = 378
A= 378/7 = 54
The total number of cars and trucks and motorcycles is 54
To get the number of motorcycles can be calculated through
a. The total number of cars and trucks and motorcycles subtracted by the number of cars and trucks = 54-42=12 or use the ratio which is
2/9 × 54 = 2×6=12
