The bug covered a distance of 65 because 78 - 13 = 65
and it’s average speed was 13
The inequality is
13x-8≤-32
The solution
13x-8≤-32
13x-8+8≤-32+8
13x≤-24
13x/13≤24/13
x≤24/13
Step-by-step explanation:
after I answered the other one(s), you should be really able to do this yourself.
it is precisely the same method and formula just with different numbers.
what's the problem now ?
y = -16x² + 247x + 141
we assume, the ground is at 0 ft.
so, we need to solve
0 = -16x² + 247 x + 141
the general solution for such quadratic equations is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = -16
b = 247
c = 141
x = (-247 ± sqrt(247² - 4×-16×141))/(2×-16) =
= (-247 ± sqrt(61009 + 9024))/-32 =
= (-247 ± sqrt(70033))/-32
x1 = (-247 + 264.6374879...)/-32 = -0.551171497... s
x2 = (-247 - 264.6374879...)/-32 = 15.9886715... s
again, the negative solution for time did not make any sense, so, x2 is our solution.
the rocket will hit the ground after about 15.99 seconds.
Answer:
10y + 15
Step-by-step explanation:
5(2y + 3)
= 5x2y + 5x3
= 10y + 15
Answer:
Positive
Step-by-step explanation:
How much was the bag bottle and shirt. Figure that out and you get the answer. But the real answer should be negative. But the actual answer is positive.
