(3,1)(-3,-3)
slope = (-3 - 1) / (-3 - 3) = -4/-6 = 2/3
y - y1 = m(x - x1)
slope(m) = 2/3
(3,1)....x1 = 3 and y1 = 1
now sub
y - 1 = 2/3(x - 3) <===
0.15 x 40 = 6 and 40+6 = 46
So you can drive below 46 miles per hour without getting a ticket
Hope this helps!
Hello,
f(4)=f(2*2)=f(2)+f(2)=3+3=6
f(8)=f(2*4)=f(2)+f(4)=3+6=9
f(16)=f(2*8)=f(2)+f(8)=3+9=12
f(32)=f(2*16)=f(2)+f(16)=3+12=15
Each person will get one third
Intersecting the x axis means y is 0
plug y=0 in the equation and solve for x to see if there are real solutions
x^2-10x+0+0=-30
x^2-10x+30=0
this cannot be factored, so let's see if b^2-4ac is bigger than 0
10^2-4*1*30=-20
so the solutions for this equation are not real numbers, therefore the answer is no.
