Answer:
x^6 i think because you add the exponents
Answer:
see below (upper left)
Step-by-step explanation:
When the x-values are sequential, a linear function will have y-values that differ by the same amount.
The upper left table has y-values that differ by -2.
The upper right table has y-values that differ by 2, -6, 2. These values are not the same.
The lower left table has y-values that differ by -1, 5, -13. These values are not the same.
The lower right table has y-values that differ by 1, 3, 5. These values are not the same.*
__
The upper left table represents a linear function.
_____
* The <em>2nd</em> differences are a constant 2, so this table represents a <em>2nd</em>-degree polynomial.

Answer: -13x^2 + 10x + 4
Step-by-step explanation:
group all of the same variables together to simplify the equation.
-7 - 6 = -13 // the x^2 value
-5 + 15 = 10 // the x value
4 is the only number without an exponent so leave it alone.
Answer:
Speed of car B is 33 km/h and speed of car A is ![45\,\,km/h](https://tex.z-dn.net/?f=45%5C%2C%5C%2Ckm%2Fh)
Step-by-step explanation:
Let speed of car B be
km/h
Speed of car A is 12 km/h more than car B.
Therefore,
Speed of car A =
km/h
Distance = Speed × Time
Distance travelled by car A in 4 hours =
km =
km
Distance travelled by car B in 4 hours =
km
Also, cars A and B are 312km apart after 4 hours.
![48+4x+4x=312\\48+8x=312\\8x=264\\\\x=\frac{264}{8}\\\\x=33\,\,km/h](https://tex.z-dn.net/?f=48%2B4x%2B4x%3D312%5C%5C48%2B8x%3D312%5C%5C8x%3D264%5C%5C%5C%5Cx%3D%5Cfrac%7B264%7D%7B8%7D%5C%5C%5C%5Cx%3D33%5C%2C%5C%2Ckm%2Fh)
Speed of car B is 33 km/h and speed of car A is ![12+x=12+33=45\,\,km/h](https://tex.z-dn.net/?f=12%2Bx%3D12%2B33%3D45%5C%2C%5C%2Ckm%2Fh)
