Answer:
{(0,-5), (1, -3), (2, -1), (3, 1)
Step-by-step explanation:
If you plug in 1 for x you get f(x)=2(1)-5 which equals 2-5=-3
You would repeat these steps just going up by one number every time
It takes 6 seconds for it to hit the ground.
0 = -5x²+20x+60
We can solve this by factoring. First factor out the GCF, -5:
0 = -5(x²-4x-12)
Now we want factors of -12 that sum to -4. -6(2) = -12 an -6+2 = -4:
0 = -5(x-6)(x+2)
Using the zero product property, we know that either x-6=0 or x+2=0; this gives us the answers x=6 or x=-2. Since we cannot have negative time, x=6.
umm I don't know hehe oops
Answer:
x=4
Step-by-step explanation:
2x-3=5
Add 3 to both sides
2x=8
divide both sides by 2
x=4
Rational numbers can be written as a fraction
