Y = x² - 8x + 29
y = (x² -8x +4²) + 29 -4² . . . . add and subtract the square of half the x-coefficient
y = (x -4)² + 13 . . . . . . . . . . . . simplify

The appropriate choice is
  C. y = (x - 4)² + 13

Identify the probability to the nearest hundredth that a point chosen randomly inside the rectangle is in the square. Only answe
wel

Answer:

0.07

Step-by-step explanation:

we know that

The probability that a point chosen randomly inside the rectangle is in the square is equal to divide the area of the square by the area of rectangle

Let

x-----> the area of square

y----> the area of rectangle

P -----> the probability

P=\frac{x}{y}

<em>Find the area of square (x)</em>

A=5^{2}=25\ in^{2}

<em>Find the area of rectangle (y)</em>

A=25*15=375\ in^{2}

Find the probability P

P=\frac{25}{375}=0.07

-1+5x≥-16 I dont know how to solve
olasank [31]

Answer:  x \ge -3

Explanation:

Follow PEMDAS in reverse to undo what's happening to x.

We first add 1 to both sides, then divide both sides by 5 to fully isolate x.

Refer to the steps below to see what I mean.

-1 + 5x \ge -16\\\\5x \ge -16+1\\\\5x \ge -15\\\\x \ge -15/5\\\\x \ge -3\\\\

The inequality sign stays the same the entire time. The only time it flips is when you divide both sides by a negative number.

The solution set for x is anything -3 or larger.

If x was an integer, then we could say the solution set is {-3, -2, -1, 0, 1, 2, 3, 4, 5, 6, ...}
