The piecewise function tells us to use 3x-5 if the input (x-value) is anything greater than or equal to -4. Let's just plug in -3 for x and that will be your answer:

f(-3) = 3(-3)-5 = -9-5 = -14

Therefore, your answer is A, -14.

During his versus non school football team Wade made 5 of 9 field goals he tried during his second season he made 11 of the 15 f
erastovalidia [21]

Answer:

  second season

Step-by-step explanation:

  5/9 ≈ 0.56 . . . first season

  11/15 ≈ 0.73 . . second season

The greater fraction of field goals was made in the second season.

__

You can also compare these fractions in this way:

  {5/9, 11/15}

Multiply both by 9×15:*

  {5·15, 9·11} = {75, 99}

The second fraction is larger.

_____

* The product of the denominators is the simplest number to compute as a multiple of both denominators. A smaller value can be found by removing a factor of 3, which is the GCD of 9 and 15. If both fractions are multiplied by 9×15/3 = 45, the result is {25, 33}. IMO, that's more work.

The number of students in the four sixth-Grade classes at northside school are 26,19,34 and 21 use properties to find the total
lesantik [10]

The three properties of algebra have been used below to find the number of students in the four sixth-Grade classes which is; 100 students

<h3>How to use properties of algebra?</h3>

There are 3 addition properties and they are associative property, identity property, and commutative property.

Commutative property is one that involves the aspect of just changing the order of the addends. Thus:

26 + 19 + 34 + 21 = 21 + 34 + 19 + 26 = 100 students

Identity Property is just adding a 0 to the number that doesn't change anything. Thus: 26 + 19 + 34 + 21 + 0 = 100 students

Associative property is one that involves just changing the grouping of the addends. Thus:

(26 + 19) + (34 + 21) = (26 + 21) + (19 + 34) = 100 students

The the length of a rectangle is 9 centimeters less than four timesfour times its width. its area is 28 square centimeters. find
wel

Let w = width

then

5w-3 = length

w(5w-3) = 14

5w^2-3w = 14

5w^2-3w-14=0

(5w+7)(w-2) = 0

w = {-7/5, 2}

throw out the negative solution leaving

w = 2 centimeters

length:

5w-3 =5(2)-3 =10-3 = 7 centimeters
