Rationnel roots are divisor of -2: -1,1,-2,2
c) see picture
Answer:
no, its not
Step-by-step explanation:
it does not have an angle of 90°
It is a scalene triangle
The graphed line is y = 3/2x + 3.
In order to solve for this, we need to start by finding the slope. To find the slope, we start by selecting two points on the graph. We'll use (0, 3) and (-2, 0).
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - 0)/(0 - -2)
m = 3/2
Now that we have this, we can use a point and slope intercept form to find the intercept.
y = mx + b
0 = (3/2)(-2) + b
0 = -3 + b
3 = b
And we can use the slope and intercept to model the equation as y = 3/2x + 3
A rectangle<span> has two </span>diagonals<span>. Each one is a line segment drawn between the opposite vertices (corners) of the </span>rectangle<span>. By using the Pythagorean Theorem, we can calculate the width. We do as follows:
c^2 = a^2 + b^2
a = sqrt( c^2 - b^2 )
a = 68.74 yards</span>
It would be -7 hope this helps
