Answer:

h(4)=17

Step-by-step explanation:

Since we are just looking for h(4), all the other equations can be ignored. Then we replace the x in the equation with 4. Remember to do the multiplication before adding the numbers together according to PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction)

$h(4)=2*2+7(4)-15\\h(4)=2*2+28-15\\h(4)=4+28-15\\h(4)= 32-15\\h(4)=17$

A bus needs to cover a distance of 240 km in less than 5 hours. Which of the following inequality represents the speed (s) of th

Len [333]

Answer:

Step-by-step explanation:

Let s represent the speed of the bus.

From the information given, the bus needs to cover a distance of 240 km in less than 5 hours. The formula for calculating the speed of the bus, s is expressed as

Speed, s = distance covered by the bus/ time taken to cover the distance

Therefore,

Speed, s = 240/5 = 48 km/hr

A higher speed would ensure the bus covers the distance in less than 5 hours. Therefore, the inequality that represents the speed (s) of the bus would be

s ≥ 48
