Answer: Yes it is a solution

Work Shown:

Replace x with -2, replace y with 2. Simplify.

y > (1/2)x - 2

2 > (1/2)*(-2) - 2

2 > -1 - 2

2 > -3

The last inequality is true, so the original inequality is true when (x,y) = (-2,2)

This makes (-2,2) a solution to the inequality.

Mrs.Ruiz bought 5 bags of balloons for a party.Each bag contained 70 balloons.Andy said mrs.Ruiz bough a total of 75.Andy is inc
kirza4 [7]

Answer:

Andy added 70 to 5 instead of multiplying 70 by 5.

Step-by-step explanation:

We have been given that Mrs.Ruiz bought 5 bags of balloons for a party. Each bag contained 70 balloons. Andy said Mrs.Ruiz bough a total of 75. Andy is incorrect what error did Andy make when calculating the total number of balloons.

To find the total number of balloons in 5 bags, we will multiply number of balloons in each bag by 5.

\text{Total balloons}=5\times 70

\text{Total balloons}=350

Therefore, the total number of balloons in 5 bags would be 350 balloons.

Andy added 70 to 5 instead of multiplying 70 by 5.

70+5=75

A hovercraft takes off from a platform. Its height (in meters), 2 seconds after takeoff, is modeled by: h(x) = -3(x - 3)2 + 108
pshichka [43]

Answer:

81 m

Step-by-step explanation:

At take off t = 0, substitute x = 0 into h(x)

h(0) = - 3(0 - 3)² + 108 = - 3(9) + 108 = - 27 + 108 = 81 m

Let f(x)=(x^2)(e^5x)<br><br> find the derivative f'(x) and the second derivative, f"(x)
Wittaler [7]
F ` ( x ) = ( x² )` · e^(5x) + x² · ( e^(5x) )` =
= 2 x · e^(5x) + 5 e^(5x) · x² =
= x e^(5x) ( 2 + 5 x )
f `` ( x ) = ( 2 x e^(5x) + 5 x² e^(5x) ) ` =
= ( 2 x ) ˙e^(5x) + 2 x ( e^(5x) )` + ( 5 x² ) ` · e^(5x) + ( e^(5x)) ` · 5 x² = 
= 2 · e^(5x) + 10 x · e^(5x) + 10 x · e^(5x) + 25 x² · e^(5x) =
= e^(5x) · ( 2 + 20 x + 25 x² )
