You can use the discriminant rule, which is :
b^2 -4ac
“exactly one solution” means that it is equal to zero
so:
b^2 -4(4)(9)=0
b^2 -4(36)=0
b^2 -144=0
b^2=144
square root both sides
b=12 or -12

P(over 6 ft) = 8/27
P(good aim) = 7/27
P(over 6 ft of good aim) = 8/27 + 7/27 = 15/27 = 5/9
Answer:
The first one is not liner
Step-by-step explanation:
This isn't linear because the y values increase inequally. It adds 2 and then 3 instead of keeping a constant rate
Answer:
the slope is 4/1 because it's 4x and the y intercept is -4
Answer:
-2
