0.36363636363 is the answer
I believe the answer is 5. I multiplied 5 to -4 and that’s -20 and I’m guessing since slope-intercept form is y=Mx+b I’m thinking b=4 and the slope being 5 matches the output. -16=5(-4)+4
Answer:

Step-by-step explanation:
The quadratic formula is:

The discriminant of a quadratic is just the expression under the square root, or
. This can tell us the number of solutions a quadratic has.
If the discriminant is:
- Positive = 2 real solutions
- Equal to Zero = 1 real double/repeated solution
- Negative = 0 real solutions, but 2 imaginary solutions
Our quadratic equation has a discriminant of 5, which is positive. Therefore, it has 2 real solutions.
Answer:
25 mm^2
Step-by-step explanation:
Because the sides of a square are all equal, that means the length = 5 and the width = 5.
To find the area, you do length * width so for this square it would be 5 * 5 = 25.
Slope intercept form is y= form
4y+8=0
-8 both sides
4y=-8
÷4 both sides
y=-2
