Answer:
the green box is 0
Step-by-step explanation:
we are asked to find the <u>x-intercept</u>, which means y = 0
(x, y)
Another way to test this is plug it in 1 for x! (1, y) where x = 1
y = 0
Answer:
The first option
Step-by-step explanation:
5*2=10
5*3=15
5*4=20
so it should start with [10 15 20]
Answer:
c=-1/4
Step-by-step explanation:
Y=2x+c=2(x+c/2), so m=2.
To be tangent we need to check y’ of parabola: y’=2x+3.
So for some x it must be 2x+3=2 (cause m=2). We have x=-1/2.
Now we use x=-1/2 to find y from 2nd equation (equation of parabole): we got y=1/4-3/2=-5/4.
So tangent has point (-1/2,-5/4).
Put that point in firts equation (equation of line): -5/4=-1+c,
so we have c=-1/4.
