Which system of inequalities is graphed below? - 10 -8 -8
-4
4
B
8
10
-8
-8-
-10

Option (1)

Step-by-step explanation:

Parent function for both parabolas graphed is, y = x²

For the large parabola,

This parabola is formed by translating the parent function 4 units downwards.

So the equation will be, y = x² - 4

Now graph of the inequality shows the dotted line with shaded area inside the parabola,

Equation of the parabola will be,

y > x² - 4

Similarly, equation of the other parabola will be,

y < x² + 6 [Since shaded region is the region outside the dotted lines of the parabola]

So the system of inequalities will be,

y > x² - 4

y < x² + 6

Therefore, Option (1) will be the answer.

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

step-by-step explanation: yes
