Answer:
option-D
Step-by-step explanation:
we are given
Let's assume it is equal to 0
We can use quadratic formula
Suppose, we are given quadratic equations as
we can compare and find a,b and c
a=1 , b=2 , c=4
now, we can plug values
and we get
now, we can simplify it
and we get
Answer:
The y-intercept is about 25.385
Step-by-step explanation:
Calculate slope from difference in y-values divided by difference in x-values.
-15/13 is slope.
Use slope-intercept form.
Y= mx + b
Substitute values from given coordinates for y and x, then solve for b
-60 = -15/13(74) + b
-60 = -85.385 + b
-60 +85.385 = b
25.385 = b
