Answer:
y = x
Step-by-step explanation:
Slope-intercept form is the form that looks like
... y = mx + b . . . . . . for slope m and y-intercept b
The line connecting points D and E has slope 1 and y-intercept 0, so the equation is ...
... y = 1·x + 0
... y = x . . . . . . without the identity elements
_____
<em>Comment on the marked choice</em>
The choice that is marked is the equation in <em>point-slope form</em> using the point E (4, 4). That is not the form requested by the problem.
Answer:
9090 kilograms
Step-by-step explanation:
To find the number of kilograms per dragon, we divide the amount of meat by the number of dragons.
4545/22 kilograms per dragon
Now we can multiply by the 44 dragon that she has.
4545/22 * 44 = 9090 kilograms
Answer: 
Step-by-step explanation:
We know that the standard quadratic equation is ax^2+bx+c=0
Let's compare all the given equation to it and , find discriminant.
1. a=2, b= -7, c=-9
So it has 2 real number solutions.
2. a=1, b=-4, c=4
So it has only 1 real number solution.
3. a=4, b=-3, c=-1
So it has 2 real number solutions.
4. a=1, b=-2, c=-8
So it has 2 real number solutions.
5. a=3, b=5, c=3
Thus it does not has real solutions.
