Greeting homo sapien. I'm assuming you're trying to find the number of giraffes. First we got to establish the variables.
X = # of giraffes
Y = # of elephants
Now let's write the equations
Equation #1
Y = 3X + 4
Now I'm also assuming you meant to write there are 23 more elephants than giraffes, so it would look like this.
Y = X + 23
Now just substitute Y's so you creat an equation with X being the only variable.
X + 23 = 3X + 4
Simplify
2X = 19
X = 9.5
So APPARENTLY there are 9.5 giraffes.... not sure how to get half a giraffe buuuuuuuuut oh well.

Omari and his two cousins received the same amount of money to go to the movies. Each boy spent $15. Afterward, the boys had $30
Jlenok [28]

Answer:

Each boy recieved $25.25 each

Step-by-step explanation:

First, you add up all the money the 3 boys spent.

15+15+15=45

Then you add the sum of the equation to the amount all the boys had afterward.

45+30.75=75.75

Finally, you divide that product to 3 boys.

75.75/3=25.25

Therfore the answer is $25.25 each.

3^2 - 2x + 4 and g(x) = 5x^2 + 6x - 8 find f-g(x)
sveta [45]

Answer:

For the given functions f(x) and g(x) (f-g)(x) = -2x^{2}  - 8x +12

Step-by-step explanation:

Here, the given function are:

f(x)  = 3x^{2}  - 2x+ 4\\g(x) = 5x^{2}  + 6x -8

Now, simplifying for (f-g)(x)  =  f(x) -  g(x):

f(x) - g(x)  = (3x^{2}  - 2x+ 4) - (5x^{2}  + 6x -8)

 = 3x^{2}  - 2x+ 4- 5x^{2}  - 6x +8

Doing operation on LIKE TERMS,  we get

f(x) -  g(x) = ( 3x^{2}- 5x^{2})   + (-2x - 6x)  +( 4 +8) = -2x^{2}  - 8x + 12

Hence, for the given functions f(x) and g(x) (f-g)(x) = -2x^{2}  - 8x +12
