Step-by-step explanation:
The slope-intercept form of an equation of a line:
y = mx + b
m - slope
b - y-intercept
y = 1 - 3x = -3x + 1
slope = -3
y-intercept at 1
y = 3x - 1
slope = 3
y-intercept at -1
x - 3 = y → y = 1x - 3
slope = 1
y-intercept at -3
x + 3 = y → y = 1x + 3
slope = 1
y-intercept at 3
Answer:
Theres no picture........
Step-by-step explanation:
Answer:
All the intervals that contain the number are solution of the problem
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
-------> equation in vertex form
The vertex is the point
The x-coordinate of the vertex is
The only way you have of finding the length of the missing side is
to ASSUME that the lengths of all 3 of them form a Pythagorean
triple. You know that you can go ahead and do this when you see
the little red 'corner' drawn in one vertex of the triangle. Then you
know that the angle is a right angle, the triangle is a right triangle,
and the sides form a Pythagorean triple.
Then (missing side) = √( 1.7² - 1.5²)
= √(2.89 - 2.25)
= √0.64 = 0.8 .
Without that little red box corner-symbol, there would be no way.
You would not stand a chance.
