Christopher's best time in a race is four seconds faster than his second-best time. his second best time is 1 1/3 times slower t

a_sh-v [17]

If his best time is x, and the best time is smaller, then (1+1/3)*x=his second best time. If x+4=his second best time (since his second best time is 4 seconds slower), then (1+1/3)*x=x+4. Multiplying it out, we get (3/3+1/3)*x=x+4
=4x/3=x+4. Subtracting x from both sides, we get 4x/3-3x/3=x/3=4. Multiplying both sides by 3, we get x=12=his best time

The sum of two numbers is 51. Four times the smaller number is 24 more than the larger number. What are the numbers?

KiRa [710]

The smaller number is 15 and larger number is 36.

Step-by-step explanation:

Let,

Smaller number = x

Larger number = y

According to given statement;

The sum of two numbers is 51.

x+y = 51 Eqn 1

Four times the smaller number is 24 more than the larger number.

4x = y+24

4x - 24 = y

y = 4x-24 Eqn 2

Putting value of y from Eqn 2 in Eqn 1

$x+(4x-24)=51\\x+4x-24=51\\5x=51+24\\5x=75$

Dividing both sides by 5

$\frac{5x}{5}=\frac{75}{5}\\x=15$

Putting x=15 in Eqn 2

$y=4(15)-24\\y=60-24\\y=36$

The smaller number is 15 and larger number is 36.

Find the inverse of the function.<br> y=3x–5

PIT_PIT [208]

Step-by-step explanation:

it means that x has now to be the result variable, and y the input variable.

so,

y = 3x - 5

y + 5 = 3x

x = (y + 5)/3

and as a final touch, to make the inverse a "normal function", we rename x to y and y to x and get

y = (x + 5)/3

as the inverse function
