Answer:
what does that mean
Step-by-step explanation:
Answer:
y = x - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = and c = - 4 , then
y = x - 4 ← equation of line
The Pythagorean Theorem allows you to find the unknown lengths of a leg or the hypotenuse of a triangle. In doing this you can also find the size of angles using sine, cosine, tangent, etc.
Answer:
x=(2+ √-32)/2 or x=(2- √-32)/2
Step-by-step explanation:
x^2 - 2x = -9
x^2 - 2x + 9 =0
x = 2± (√(-2)^2 - 4*1*9)/2*1
Use the quadratic formula in the expression using a=1, b= -2, c=9
x = 2±√4-36 /2
x = 2+√4-36 or x = 2 - √4 - 32 /2
x = (2+√-32) /2 or x=( 2 - √-32 )/2
