Two cars travel along a highway at the same speed.
Mazyrski [523]

Answer:

30 mins

Step-by-step explanation:

<em>speed = distance/ time </em>

speed of car A

= 20/ 12 km/ min

= 5/ 3 km/ min

also, speed of car A = speed of car B

speed of car B = 5/ 3 km/ min = 50km / time taken (in mins)

\frac{5}{3}  =  \frac{50}{t}

5t  = 150

t = 30

=> t = 30 mins

If f(x) = 5x + 4, which of the following is the inverse of Ax)?
Levart [38]

Answer:

f^{-1} (x) = \frac{x-4}{5}

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 5x + 4 ( subtract 4 from both sides )

y - 4 = 5x ( divide both sides by 5 )

\frac{y-4}{5} = x

change x to f^{-1}(x) and y back to x, thus

f^{-1}(x) = \frac{x-4}{5}

Triangle XYZ is obtuse which list could represent the angle measures of triangle XYZ?
asambeis [7]
An obtuse triangle must have an angle greater than 90degrees (cannot equal 90). Therefore, A. would be the correct answer. This is because A. is the only set of angles that includes an angle greater than 90. Also, all angle measures add up to equal 180degrees.
