Answer:

4x² + 4x + 5

Step-by-step explanation:

Note that (f - g)(x) = f(x) - g(x), thus

f(x) - g(x)

= 5x² - 3 - (x² - 4x - 8 ) ← distribute parenthesis by - 1

= 5x² - 3 - x² + 4x + 8 ← collect like terms

= 4x² + 4x + 5

M=-1/4; (4,0) Please help, I don't understand. :(

Hmm, this seems to make no sense.

If you mean't

x = -1/4?

The answer would be false if it was x, but this has no context

What us the equation of the line that passes through point (2,5) and (0, -2)

erastovalidia [21]

Answer:

y = 7/2 x -2

Step-by-step explanation:

First we need to find the slope

m = (y2-y1)/(x2-x1)

= (-2 -5)/(0-2)

=-7/-2

= 7/2

We know the y intercept is -2 ( The x coordinate is 0)

Using the slope intercept form of the equation

y = mx+b where m is the slope and b is the y intercept

y = 7/2 x -2

Find f(x) and g(x) so that the function can be described as y = f(g(x)). y = 3/ square root of 3x + 4

Elis [28]

Well, your equation y=3/SQRT(3x+4) should be rationalized, but that's not what you want.

If f(x) = 3/SQRT(x+4) and g(x) = 3x

f(g(x)) then = 3/SQRT(3x+4), but rationalizing this = 3SQRT(3x+4)/(3x+4)

Solve the unknown viable 7c/12 + 5c/16=15/48 +c

Mashutka [201]

deconstructing
48 : 2 = 24
24 : 2 = 12
12 :2 = 6
6 : 2 = 3
3 : 3 = 1
2 * 2 * 2 * 2 * 3 = 48
...................................
16 : 2 = 8
8 : 2 = 4
4 : 2 = 2
2 : 2 = 1
2 * 2* 2 * 2 = 16
..................................
12 : 2 = 6 $\frac{7c}{12} + \frac{5c}{16} = \frac{15}{48} + c \\ \\ \frac{7c*4}{12*4} + \frac{5c*3}{16*3} - \frac{15}{48} = c \\ \\ \frac{28c + 15c}{48} - \frac{15}{48} = c \\ \\ 48c = 43c - 15 \\ \\ 48c - 43c = -15 \\ \\ 5c =- 15 \\ \\ c = -3
$ 
6 : 2 = 3
3 : 3 = 1
common denominator 48
