Write the quadratic equation whose roots are 6 and -2, and whose leading coefficient is 4,

Zinaida [17]

Answer:

4x^2 - 16x - 48 = 0.

Step-by-step explanation:

In a factor form it is:

4(x + 2)(x - 6) = 0

Convert to standard form:

4(x^2 - 4x - 12) = 0

4x^2 - 16x - 48 = 0.

Marcie solved the following inequality and her work is shown below:. . −2(x − 5) − 12 ≤ 4 + 6(x + 3). −2x + 10 − 12 ≤ 4 + 6x + 1

BartSMP [9]

All steps that Marcie did are right, but she forgot to change sign in last step.

Consider the inequality

$-2(x - 5) -12 \le 4 + 6(x + 3).$

Then

$-2x+10-12 \le 4 + 6x+18.$

Group the numbers:

$-2x-2 \le 6x+22.$

Separate terms with x and without x in different sides:

$-2x-6x \le 22+2.\\-8x\le 24.$

The coefficient at x is -8 and it is negative, then dividing the inequality by -8 you have to change sign in opposite:

$x\ge -3.$

Answer: Marcie forgot to change sign in last step.

Answer:

x = 16

Step-by-step explanation:

The angle bisector divides the sides proportionally.

(x -4)/9 = x/12

4(x -4) = 3x . . . . . . . multiply by 36

x = 16 . . . . . . . . . . . . add 16-3x to both sides, simplify
