The illustration below shows the graph of yyy as a function of xxx.
Alisiya [41]
  1. The slope of the graph of the function is equal to 0 for x between x = -3 and x = -2.
  2. The slope of the graph of the function is equal to 0 for x between x = 3 and x = 4.
  3. The greatest value of y is y = 4.
  4. The smallest value of y is y = -3.

<h3>How to complete the sentences?</h3>

By critically observing the graph shown in the image attached below, we can logically deduce that the slope of the graph of this function is equal to 0 for x, between x = -3 and x = -2.

Similarly, the slope of the graph of this function is also equal to 0 for x, between x = 3 and x = 4.

Based on the graph (see attachment), the greatest value of y is 4 while the smallest value of y is -3.

Need help with 34 , 35 and 36 . <br> full details pleaseee and thank you :)
Nat2105 [25]

Answer:

34. A negative number multiplied by a positive number will always have a negative product. The right answer should be -8.14.

35. When dividing fractions, you have to use the same-change-flip rule. The work should be like this: -1/4 x 2/3 = -2/12 = -1/6. The correct answer is -1/6.

36. In this problem, you need to convert 2 1/5 into a decimal, then multiply by -30. (2.2 x -30) The answer is -66 degrees.

The area of a rectangular garden is 38 1/4 square meters the width of the garden is 4 1/2 meters what is the length of the garde
Snowcat [4.5K]

Hello...

Area is measured by the formula A=L*W (Area = Length X Width)  We know the area is 38 1/4 and the width is 4 1/2. It is easiest to convert them to decimals and solve. 38 1/4 = 38.25 and 4 1/2= 4.5 .    so, 38.25 = 4.5 * W

To solve for Width, we need to isolate it by getting 4.5 on the other side. To do this, we divide by 4.5 on both sides of the equals sign. this will give us W=8.5 or Width = 8 1/2 meters.
