Answer:

The integer that represents the total change in her pay over a 5 - day period is '20'.

Step-by-step explanation:

On Monday , Casey made $60.

Each day , her pay decreased by $4.

So, in 5 days the value decreased by 4\times5=20 dollars

So, total change was 20.

We can also say its negative because there is a decrease in the value.

Hence, the integer that represents the total change in her pay over a 5 - day period is '20'.

The answer is $260 first you do 60-4 that equals 56 and then you do 56-4= 52 and you do 52-4 = 48 then 48-4=44 then you do 60+56= 116 and then you do 116+52=168 and then do 168+48= 216 and then 216+44=260 the answer is 260

Vilka [71]

Answer: 17 rows, 7 of yellow flowers and 10 of orange flowers.

Step-by-step explanation:

We have 40 orange flowers

we have 28 yellow flowers.

The total number of flowers is 40 + 28= 68

Now, we want to find the maximal comon factor between 28 and 40 (that will be the number of flowers in each row)

for this, we took the smallest number and find its factors, and then we see if those factors are also of the greater number.

28/1 = 28 ----> 40/28 is not integer, so 28 is not a factor of 40.

28/2 = 14 ----> 40/14 is not integer, so 14 is not a factor of 40.

28/3 is not integer.

28/4 = 7 ----> 40/7 is not integer, so 7 is not a factor of 40.

28/5 is not integer.

28/6 is not integer.

28/7 = 4, 40/4 = 10, so 4 is a factor of both 28 and 40.

Then the maximum number of flowers that we can put in each row is 4.

this means that we have:

28/4 = 7 rows of yellow flowers (with 4 flowers each)

40/4 = 10 rows of orange flowers (with 4 flowers each)

a total of 17 rows.

If a(x) = 2x - 4 and b(x) = x + 2, which of the following expressions produces a quadratic function?
Elanso [62]

Answer:

(ab)(x)

Step-by-step explanation:

Data provided in the question

a(x) = 2x - 4

b(x) = x + 2

Now we go through each options

First option

(ab)(x)=(2x-4)(x+2)

=2(x-2)(x+2)

=2(x^2-4)

=2x^2-8

Second option

\dfrac{a}{b}(x)=\dfrac{2x-4}{x+2}

Third option

(a-b)(x)=(2x-4)-(x+2)

=2x-4-x-2

= x - 6

Fourth option

(a+b)(x)=(2x-4)+(x+2)

=2x-4+x+2

= 3x - 2

As we can see from the above options only option A is correct i.e it only produced a quadric function
