Answer:
x > -3 or -3 < x < 3 or x > 3
Step-by-step explanation:
- 9
= (x + 3)(x - 3)
the undefined singularity points are at x = 3 and x = -3
x > 3 or x > -3
Answer:
Fish with -1 foot
Step-by-step explanation:
- = under
+= above
If you set your water level to 0 then:
-1 +0 = -1 so the fish is 1 foot under the water level
-5 +0 = -5 do the fish is 5 foot under the water
And the last fish either jumped super high or it was hanging on a fishing line becouse it was 8 feet above the water level
So the fish that was the closes to the water level was the fish with -1
Y=mx+b
m=slope
b=yint
two points
cost=y
(4,5.5) and (7,7.75)
slope=(y2-y1)/(x2-x1)
slope=(7.75-5.5)/(7-4)=2.25/3=0.75
y=0.75x+b
find b
(4,5.5)
x=4
y=5.5
5.5=0.75(4)+b
5.5=3+b
minus 3 fromboth sides
2.5=b
y=0.75x+2.5
3 hours
y=0.75(3)+2.5
y=2.25+2.5
y=4.75
answer is D
Answer:
A. 1 centimeter
Step-by-step explanation:
To solve you could use a proportion, in this case, 2/8=x/4. You can cross multiply to find the value of x. 8x=2*4, then simplify, 8x=8. Finally isolate the variable by dividing by 8. 8x/8=8/8, simplified that equals x=1.
