Point of intersection is: (6,80)

Step-by-step explanation:

In order to find the point of intersection for two lines we solve the equations.

Given equations are:

$y = 10x+20\ \ \ Eqn1\\y = 5x+50\ \ \ Eqn2$

Putting y = 5x+50 in equation 1

$5x+50 = 10x+20\\50-20 = 10x-5x\\5x = 30\\\frac{5x}{5} = \frac{30}{5}\\x = 6$

Putting x=6 in equation 1

$y = 10(6)+20\\y = 60+20\\y = 80$

Hence,

Point of intersection is: (6,80)

If it took Carlos an hour to cycle from his house to the library yesterday, was the distance that he cycled greater than 6 miles

julia-pushkina [17]

Answer:

Option 2 is the correct answer.

Step-by-step explanation:

We know that

$Speed=\frac{Distance}{time}$

We have 1 mile = 5280 feet thus 6 miles = 31680 feet

Similarly 1 hour = 3600 seconds

Applying values in the equation above we get

$Speed=\frac{31680feet}{3600sec}\\\\Speed=8.8feet/sec$

Thus his average speed is less than 18feet/sec

Dahasolnce [82]

I belive it is S=2C. Even if it was three years ago, if Sherman was twice as old then, then he would be twice as old now. So you can get rid of the three years ago. if someone is twice as old, it is the same as doubling it.
