Answer : Option A
Explanation:
we can clearly see that from x+ y=5 we can substitute y = 5-x in y = 9x^2
Option B is clearly incorrect x can not be y -5
Option C is incorrect because y can not be 5 +x
Option D is incorrect because its y = 9x^2 not y^2 =9x^2 so y can not be 3x
if its y^2 = 9x^2 then only implies y = 3x
The answer is G because you have to go 5 units to the left and 4 units up from 0 in the second quadrant
Answer: B) x ≥ -2
<u>Step-by-step explanation:</u>
Domain represents all of the x-values.
In the given graph, the x-values start at -2 and go continuously through to positive infinity.
Therefore, x ≥ -2
Answer:
It's D
Step-by-step explanation:
Well first you have to divide 620/20 which is 31. So his car goes 31 miles per gallon so you have 2 gallons and .25 of a gallon. So first off 2*31=62 miles then the 1/4 or .25. Multiply the 31 by .25 which is 7.75 now add 62 and 7.75 and you get how far his car can go.
62+7.75=69.75 miles
