Answer:
15.4 gallons .
Step-by-step explanation:
The rate of gas used = 380/14 = 27.14 gallons per gallon.
So for each gallon used you drive 27.14 miles.
So number of gallons used when travelling 418 miles = 418/27.14
= 15.4 gallons .
Answer:
1. x=4
2. x=6
Step-by-step explanation:
I've attached the graphs here:
Clearly, the solution for first one is(Reminder: the solution is the x-intercepts, when y is zero):
x=4
And the second is:
x=6
Hope this helps!

Step-by-step explanation:
<u>Definitions</u>
Integer: A whole number that can be positive, negative, or zero.
Rational Number: A number that can be expressed as the ratio of two integers (where the denominator does not equal zero).
Irrational Number: A real number that <u>cannot</u> be written as a rational number.
![\sf -8.2183 \times 10000=-82183](https://tex.z-dn.net/?f=%5Csf%20-8.2183%20%5Ctimes%2010000%3D-82183)
![\implies \sf -8.2183=-\dfrac{82183}{10000}](https://tex.z-dn.net/?f=%5Cimplies%20%5Csf%20-8.2183%3D-%5Cdfrac%7B82183%7D%7B10000%7D)
Therefore, -8.2183 can be expressed as a <u>rational number</u>.
π is an <u>infinite decimal</u>, so it cannot be expressed as a rational number.

is an irrational number.
![\sf 9+ \sqrt{4}=9+\sqrt{2^2}=9+2=11](https://tex.z-dn.net/?f=%5Csf%209%2B%20%5Csqrt%7B4%7D%3D9%2B%5Csqrt%7B2%5E2%7D%3D9%2B2%3D11)
As 11 can be expressed as ¹¹/₁ then 9 + √4 is <u>rational</u>.
<u>Conclusion</u>
Therefore, the numbers that are irrational are:
