Answer:

1 and 5/12

Step-by-step explanation:

2/3 + 3/4 = 8/12 + 9/12 = 17/12 = 1 and 5/12.

We need to make the denominators the same number. To do this we need to find a number that the denominator 3 and the denominator 4 have in common. The closest number that 3 and 4 have in common is 12. We then multiple the fraction 2/3 by 4/4 to get 9/12. Then we multiply the fraction 3/4 by 3/3 to get the fraction 9/12. Then we add them together and get 17/12. Then we simply if further and get 1 and 5/12.

Explain why 8 x ¾ is the same as adding ¾ + ¾ + ¾ + ¾ + ¾

Mekhanik [1.2K]

8 x ¾ is the same as adding ¾ + ¾ + ¾ + ¾ + ¾

because, when you are adding 3/4

8 times, you are 3/4 plus itself,

eight times,

so you are doing 3/4*8

Which number line represents the solution set for the inequality –4(x + 3) ≤ –2 – 2x?

Yuliya22 [10]

<span>–4(x + 3) ≤ –2 – 2x

>>.....-4x -12 </span>≤ -2 -2x

>> -12 +2 ≤ +2x

>> - 10 ≤ 2x

>> -5 ≤ x............>> x >= -5

This answer is not represented in the pictures you attached

The line starts in x = -5 and goes up to infinity

The height 'h' (in feet) of a ball in a baseball game can be modeled by h = -16t² + 28t + 8 , where 't' is the time (in seconds)

lidiya [134]

Answer:

a) No. t < 0 is not part of the useful domain of the function

b) 2.0 seconds

Step-by-step explanation:

a) A graph of the function is shown below. It shows t-intercepts at t=-0.25 and t=2.0. We presume that t is measured forward from some event such as the ball being thrown or hit. The model's predicted ball location has no meaning prior to that event, when values of t are negative.

b) It is convenient to use a graphing calculator to find the t-intercepts. Or, the equation can be solved for h=0 any of several ways algebraically. One is by factoring.

h = 0 = -16t² +28t +8 . . . . . . . . . . . . the ball hits the ground when h = 0

0 = -4(4t² -7t -2) = -4(4t +1)(t -2)

This has t-intercepts where the factors are zero, at t=-1/4 and t=2.

The ball will hit the ground after 2 seconds.
