Slope : -1/3
Y - intercept : -5
Answer:
y=12/5 (in decimal notation y=2.4)
Step-by-step explanation:
the value of 7y-2 = 10 more than 2y
7y-2 = 10+2y
7y-2y = 10+2
5y = 12
y = 12/5
y = 2.4
Answer:
3 gallons
Step-by-step explanation:
We need to find the area of the floor first:
25.6*15.2=389.12
Now we divide the surface area by gallons of polyurethane.
389.12÷180=2.161777777777777777777777777777....≈2.16 gallons needed. But OH WAIT! You can't buy 0.16 of a gallon so you need 3 gallons.
The total numbers of cats, birds and dogs in the shelter is 37
the probability of selecting a cat from the shelter is 10/37
the probability of selecting a dog from the shelter is 15/37
probability of a dog and a cat is given by
10/37*15/37=150/1369
we know that
If the only factors a polynomial are and itself, then that polynomial is prime.
so
If the polynomial has at least one root (one x-intercept) then the polynomial is not prime
Using a graph tool
<u>case 1) </u>
see the attached figure N 1
The polynomial has one root-------> the polynomial is not prime
<u>case 2) </u>
see the attached figure N 2
The polynomial has three roots-------> the polynomial is not prime
<u>case 3) </u>
see the attached figure N 3
The polynomial has zero roots-------> the polynomial is prime
<u>case 4)</u>
see the attached figure N 4
The polynomial has two roots-------> the polynomial is not prime
therefore
<u>the answer is</u>
------> is prime
