First distribute the 3 so you'll have:

12+12x=12x+12

Next you subtract 12 from both sides and you'll get:

12x=12x

then you divide both sides by 12 and you get:

x=x

Problem: 3(4+4x)=12x+12

The first thing that you need to do is distribute 3(4+4x).

12+12x=12x+12

Subtract 12x from both sides.

12=12

This means that the equation has infinitely many solutions.

I hope this helps you :)

Mattie uses the discriminant to determine the number of zeros the quadratic equation 0 = 3x2 – 7x + 4 has. Which best describes

r-ruslan [8.4K]

Answer:

The equation has two zeros because the discriminant is greater than 0.

Step-by-step explanation:

3x^2 – 7x + 4

a=3 b = -7 c=4

The discriminant is

b^2 -4ac

(-7)^2 - 4(3)(4)

49 - 48

Since the discriminant is greater than zero, there are two real solutions

PLEASE HELP WILL MARK BRAINLIEST

Answer:

f(-4) = 5

Step-by-step explanation:

Explanation of

| 5, x < -3

f(x) | 2x² - 4, -3 ≤ x ≤ 4

| 1 - 6x , x > 4

When the x in f(x) is less than -3 than f(x) = 5

When the x in f(x) is greater than -3 but less than 4 then f(x) = 2x² - 4

When the x in f(x) is greater than 4 than f(x) = 1 - 6x

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now that we know this lets look back at the question.

We want to find f(-4).

Looking at the piece wise function we see that f(-4) follow x < -3 as "x" or -4 is less than -3. When x is less than -3, f(x) = 5, hence f(-4) = 5

Hello If You Have Please Help Thank You Solve for x. −7x−15<6

bonufazy [111]

Answer:

x > -22/7

Step-by-step explanation:

Given inequality:

- 7x - 15 < 6

adding 15 to both sides:

==> -7x - 15 + 15 < 6 + 16

==> -7x < 22

dividing both sides by 7:

==> -x < 22/ 7

multiplying both sides by -1

(anytime you multiply the inequality by -1 you must flip the inequality sign– replace the "<" with ">")

==> x > -22/7
