How many real solutions are there to the equation x2 − 7x + 12 = 0?
lbvjy [14]
Hi there! 

We can find the answer by factoring the equation, then setting them up equal to zero.

x² - 7x + 12 = 0
(x - 3)(x - 4) = 0

x - 3 = 0                             x - 4 = 0
     x = 3                                   x = 4

So you have two real solutions for the equation x² - 7x + 12 = 0.

Hope this helped! :)

P is at ( -1,5)

We are moving it 5 units to the right so add 5 to the x

We are moving it 7 units down so subtract 7 from the y

p'( -1+5, 5-7)

What is the value of x​
Artemon [7]

Answer:

45 degrees

Step-by-step explanation:

Angles on a straight line add up to 180 degrees.

Thus, x+3x=180

4x=180

Divide both sides by 4:

\frac{4x}{x} =\frac{180}{4}

x=45
