Two of largest mammals on earth are the blue wale and the African elephant. An adult male blue whale weighs about 170 tonnes or long tones. (1 tonne =1000 kg) Show that the weight of an adult blue whale is 1.7 * 10^5 kg.

Weight is 1.7 × 10^5 kg

Step-by-step explanation:

⇒ 170 tonnes = 170 × 1000 (1 tonne = 1000 kg)

⇒ 170 tonnes = 17 × 10^4 kg

⇒ 17 × 10^4 = 1.7 × 10^5 kg (Dividing and multiplying by 10 on both sides)

explanation

the given function is

this function has y-intercept at

-4 and a slope of 2.

note that, the graph has a positive slope.

the graph that represents this function is the straight line that moves upward from left to right.

the graph touches the y-axis at -4.

the correct choice is the graph shown in the attachment.

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
