If the number is x, then 3 times x -20 >10 and 3x-20>10. Adding 20 to both sides, we get 3x >30 and by dividing by 3 we get x >10
Answer:
The number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
Step-by-step explanation:
Given
Size of Gas = 12 gallon of gas
Distance = 456 miles
Calculating the number of miles her car travel per gallon of gas.
This in calculated by distance/size of gas
By substituton, it becomes
Number of miles = 456 miles/12 gallons ------ divide
Number of miles = 38 miles / gallon.
Hence, the number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas
when x= -4 ,f(x)=2
Step-by-step explanation:
the coordinate in which f(x) i.e y=2 is (-4,2)
thus x= -4
Answer:
see explanation
Step-by-step explanation:
To find the zeros equate g(x) to zero, that is
(x - 2)(3x + 3) = 0
Equate each factor to zero and solve for x
x - 2 = 0 ⇒ x = 2
3x + 3 = 0 ( subtract 3 from both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
Hence
smaller x = - 1
larger x = 2
