Option D: $x \geq 3$ is the solution

Explanation:

The given expression is $3 x-1 \geq 8$

We need to determine the solution of the expression.

<u>Solution:</u>

The solution of the expression can be determined by solving the expression for the variable x.

Thus, we have,

$3 x-1 \geq 8$

Adding both sides of the expression by 1, we get,

$3x\geq 9$

Dividing both sides of the expression by 3, we get,

$x \geq 3$

Thus, the solution of the expression is $x \geq 3$

Hence, Option D is the correct answer.

Feliz [49]

First convert 6 miles to yards. That would be 10,560 next divde it by 350 to get 30.1786 but you have to round it to the next lap. Therfore, youll have to run a total of 31 laps around the field.

Answer:

y = -3x^2 +3x +6

Step-by-step explanation:

For roots p and q, the equation can be written as ...

y = a(x -p)(x -q)

The value of 'a' must be determined so that the product <em>apq</em> is equal to the y-intercept. One could say that the formula is ...

y = (y-intercept)/(pq)·(x -p)(x -q)

For your given values of p = 2, q = -1, y-intercept = 6, this becomes ...

y = 6/(2(-1))(x -2)(x +1)

y = -3(x^2 -x -2) . . . . . simplifying a bit

y = -3x^2 +3x +6

Put these in order starting with the smallest.

Alexxandr [17]

Answer:

Step-by-step explanation:

$9^{\frac{3}{2} }$ = ( √9 )³ = 27

$27^{\frac{1}{3} }$ = ∛27 = 3

$125^{\frac{2}{3} }$ = ( ∛125 )² = 25

$27^{\frac{1}{3} }$ , $125^{\frac{2}{3} }$ , $9^{\frac{3}{2} }$
