On a class trip, there were 45 more girls than boys. the total number of students on the trip was 215. write and solve an equati
Evgesh-ka [11]
(b)+(b+45)=215
b = # of boys
there are 45 more girls than boys and 215 students total.
minus 45 on both sides leaving you with
(b)+(b)=170
combine like terms leaving you with
2b=170
divide both sides by 2
b=85
there were 85 boys
85+45=130
(the 45 for the # of girls more than boys)
there were 130 girls.

How can i solve number 47?
stepan [7]
Ew. Composition of functions. Ok, f(g(x)) is what that fancy notation means. So, you would take g(x) & substitute that into wherever x is in f(x). So we get something crazy like f(x)= 4 - (.5x - 2)^2 Now, we foil out the squared quantity: f(x)= 4 - (.25x^2 - x - x + 4) Can you believe they call that simplification? f(x)= 4 - .25x^2 + 2x -4 Almost there... f(x)= -.25x^2 + 2x Hope this helps!

Which function has an inverse that is also a function?
Yakvenalex [24]
The inverse of a function will also be a function if it is a One-to-One function. This means, if each y value is paired with exactly one x value then the inverse of a function will also be a function.

Option C gives us such a function, all x values are different and all y values are different. So inverse of function given in option C will result in a relation which will also be a function.

In all other options, y values are being repeated, which means they are not one to one functions.

So, the answer to this question is option C

lilavasa [31]

We presume you want to find values of x that make this true.

Subtract the right side and factor:

2x^2-5x=0\\\\x(2x-5)=0\\\\\bf{x=0\qquad\text{or}\qquad x=\dfrac{5}{2}}

Once you have factors whose product is zero, you can find the values of x that make those factors zero. A product can only be zero if one or more contributing factors is zero.

To solve 2x-5=0, you can add 5 then divide by 2:

... 2x -5 = 0

... 2x = 5

... x = 5/2

Hard to calculate first one is -1/2

Next one is 2.5/1.5 or 2 its hard to tell because of line (not clear)

Next one is -1/2 I think the numbers are small.
