In looking at it I would guess it is asking which of the points is on the line? To answer that you would have to take each point an plug it into the equation and see if it is true.

3x - 7 = y

A(9,20)
3(9) - 7 = 20
27 - 7 = 20
20 = 20 True - this point is on the line

B(5,0)
3(5) - 7 = 0
15 - 7 = 0
8 = 0 False - this point is not on the line

C(3,2)
3(3) - 7 = 2
9 - 7 = 2
2 = 2 True - this point is on the line

I hope this helps

3 over eight people ride the bus in Mrs. Mulls class. If she has 24 students how many students ride the bus?

qaws [65]

I think you divide 24 by 8 which = 3 and then times 3•3 which equals 9 so I think that 9 students out of 24 ride the bus

juin [17]

Answer:

1/18

Step-by-step explanation:

there are 12 marbles in the bag

P(choose red) = 2/12 = 1/6

P(choose blue after replacement) = 4/12 = 1/3

P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18

The inverse of the logarithmic function f(x) = log0. 5x is f−1(x) = 0. 5x. What values of a, b, and c complete the table for the

Elan Coil [88]

The value of a, b and c can be calculated using the inverse function.

The calculated the value of a= 2, b=1 and c= -2.

Given:

The function is $f(x)=\log_{0.5}x$ and its inverse is $f^{-1}(x)=0.5^x$ .

<h3>What is an inverse function?</h3>

The inverse function of a function is defined if $f$ is a function that undoes the operation of $f$ .

The inverse of $f$ exists if and only if $f$ is bijective, and if it exists, is denoted by $f^{-1}$ .

Substitute the value of x= -1 in a given inverse function and calculate the value of a.

$f^{-1}(x)=0.5^x\\
f^{-1}(-1)=0.5^{-1}\\
f^{-1}(-1)=2$

Substitute the value of x is 0 in given inverse function.

$f^{-1}(x)=0.5^x\\
f^{-1}(0)=0.5^0\\
f^{-1}(0)=1$

Substitute the value of x is 2 in given inverse function.

$f^{-1}(x)=0.5^x\\f^{-1}(2)=0.5^2\\f^{-1}(2)=-2$

Therefore, the value of a= 2, b=1 and c=-2.
