For what values of h does the equation have real solutions. √(3x-h)= x+3

Mathematics
1 answer:
Andru [333]3 years ago
4 0

Square both side to get

3x-h = (x+3)^2

distribute the squared

3x - h = x^2 + 6x + 9

subtract 3x from both sides

-h = x^2 + 3x + 9

The answer will only have real solutions if the right side is factorable

h= -19, and 2.25 are both values that would make the right side factorable

if a triangle is an equilateral triangle then the triangle has exactly three 60 angles abc is an equilateral triangle​
Artist 52 [7]

Answer:

The statement is always TRUE

Step-by-step explanation:

An equilateral triangle has all angles and all sides equal

The sum of angles in a triangle is 180 degrees.

Let each of the angles be x degrees.

Then we solve the following equation for x.

x+x+x=180\degree

\implies 3x=180

\implies x=\frac{180}{3}=60\degree

What do I write????!??!!????????!!!!!

1. Do they match? No
How do you know? When substituted y = 3(2) - 4 is 2
y = 3(4) - 4 is 8
y = 3(8) - 4 is 20 not 14. So the table isn’t fully correct.

2. Do they match? No
How do you know? Because it says she walks UP the stairs not down. So -2 doesn’t make sense.

3. Do they match? Yes
How do you know? 0 means that the pile didn’t start with 6 so when you add 3 to 0, it’s 3. (duh lol)

On day 1, it starts with 6, (1)(6) = 6, and then they added 3 rocks, so it’s 9.

Day 2, twice as many rocks, so it starts with 12 now. + 3 is 15.

Day 3 starts with 18 rocks now. + 3 is 21.
