Answer:

6.25$

Step-by-step explanation:

So lets think about this.

We need to find dollars per hour.

We have 25 for 4 hours.

What do we do?

Lets divide 25 by 4.

25/4

=

6.25 dollars

lets think of it this way. Dollars for 4 hours, divided by 4, equals dollars for 1 hour.

AnswerL

<u>6.25</u>

Hope this helps! :)

Find four consecutive even integers whose sum is 84. Find the integers.
mina [271]
Suppose the integers are n , n+2 , n+4 and n+6.
84=n+(n+2)+(n+4)+(n+6)=4n+12.
Subtract 12 from both ends to get.
72=4n.
Divide both ends by 4 to get.
n=18.
So the integers are: 18 , 20 , 22 , 24.

Determine the equation of the following polyromial that passes through point (0,6).
Ostrovityanka [42]

Answer:

Cubic polynomial has zeros at x=−1x=−1 and 22, is tangent to x−x−axis at x=−1x=−1, and passes through the point (0,−6)(0,−6).

So cubic polynomial has double zero at x=−1x=−1, and single zero at x=2x=2

f(x)=a(x+1)2(x−2)f(x)=a(x+1)2(x−2)

f(0)=−6f(0)=−6

a(1)(−2)=−6a(1)(−2)=−6

a=3a=3

f(x)=3(x+1)2(x−2)f(x)=3(x+1)2(x−2)

f(x)=3x3−9x−6

16x² +8-7x-3x2 - 13x
liq [111]

Answer:

13x^{2}-20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

What is 1 half subtract 1 tenth
Anna [14]
To solve for \frac{1}{2}- \frac{1}{10} You first need to find a common denominator.

To do so, you need to make both denominators 10 by multiplying the top and bottom of \frac{1}{2} by 5

\frac{5}{10}- \frac{1}{10}=\frac{4}{10}    Reduce by dividing both the top and bottom by 2

Your answer is \frac{2}{5}
