Which pairs are like terms in the expression below? Select all that apply.
seraphim [82]

9514 1404 393

Answer:

 B, E

Step-by-step explanation:

Like terms are ones that have the same variable, or that have no variable at all.

There are two terms with y as the variable. These are like terms.

There are two constant terms (with no variable). These are like terms.

The like term pairs are ...

  • 25y and -0.2y (B)
  • -6 and -2 (E)

What temperature is 15 degrees lower than 7degrees
BabaBlast [244]
15 degrees lower than 7 degrees means that we have to subtract.

So we have 7 degrees and it wants 15 degrees lower, so we would do 7 - 15

And so 7-15 = -8

So 15 degrees lower than 7 degrees would be -8 degrees. :)

A bakery has the following pricing for large orders of cupcakes. The first 100 cupcakes of any order
Taya2010 [7]

A piecewise function is a function that behaves differently in different intervals of its domain.

The answers are:

a)

f(x) = x*$2.00    if 0 ≤ x ≤ 100

f(x) = x*$1.75     if  100 < x ≤ 250

f(x) = x*$1.25     if    x > 250.

b)  $306.25

The given information is:

The first 100 cupcakes cost $2.00 each.

If the order is between 100 and 250 cupcakes, the cost is $1.75 each.

If the order is more than 250 cupcakes, the cost is $1.25 each.

a) Now we want to write the piecewise function, this will be:

f(x) = x*$2.00    if 0 ≤ x ≤ 100

f(x) = x*$1.75     if  100 < x ≤ 250

f(x) = x*$1.25     if    x > 250.

Above you can see the piecewise function, when you want to evaluate it, the first thing you need to do is to find at which interval the input belongs.

b) If you order 175 cupcakes you have x = 175.

This belongs to the second interval ( 100 < x ≤ 250) then we will use the second part of the function:

f(175) = 175*$1.75 = $306.25
