Answer:
y int is -4. slope is negative. slope is rise/run. in the graph is rises 2 for every 3 it goes to the left. this means your slope is 2/3
put all that together
-2/3x -4 is your equation
Answer:
8.14
Step-by-step explanation:
Ok.So to do this, you have to know the Pytharomean Theroem.If you do not know how,then that is totally ok.I will tell.So the theroem has a formula.
Down below is a image showing the variables.
Now the hypotenuse is c.And b and a are the legs.
So we can put evaluses in the formula(formula:a^2 + b^2 = c):
(6.0)^2 + (5.5)^2 = c^2
36 + 30.25=c^2
66.25=c^2
8.14 = c
So 8.14 is the anwser!
Hoped it helped!
Answer:
The given equation is -2x^2 = -8x + 8
This can be rewritten as 2x^2 - 8x + 8 = 0
Here the value of a =2, b = -8 and c = 8
Discriminant = b^2 - 4ac
Now plug in the above values in the discriminant, we get
= (-8)^2 - 4*2*8
= 64 - 64
= 0
Here the discriminant is 0, so we will get one real root.
The discriminant is equal to 0, which means the equation has one real number solution.
Hope this will helpful.
Thank you.
