Find the equation of the line in standard form containing a point P(-3.3) and slope m= -4/3<br><br>

bixtya [17]

Answer:

4x + 3y = -3.

Step-by-step explanation:

First substitute into the point-slope form:

y - y1 = m(x - x1):

y - 3 = (-4/3)(x - -3)

y - 3 = (-4/3)(x + 3)

y - 3 = -4/3 x - 4

y = -4/3 x - 4 + 3

y = -4/3x - 1 Multiply through be 3:

3y = -4x - 3

4x + 3y = -3 (answer).

Max and pedro both clean pools. Each charges a flat fee to clean a pool. Max cleans 12 pools in 8 hours and earned $270. Pedro c

marshall27 [118]

Answer:

The number of pools clean per hour is 1.5

Step-by-step explanation:

Given as :

The number of pools clean in 8 hours = 12

The number of pools clean in 7.5 hours = 9

Let The number of pools they clean per hours = x

I.e x = $\frac{8}{12}$ + $\frac{7.5}{9}$

Or, x = $\frac{24+30}{36}$

Or, x = $\frac{54}{36}$

∴ x = $\frac{3}{2}$

I.e x = 1.5

Hence The number of pools clean per hour is 1.5 Answer

If f(x) = 2x - 6 and g(x) = 3x + 9, find (f+g)(x)

valina [46]

Answer:

(f+g)(x) = 5x + 3

Step-by-step explanation:

f(x) = 2x - 6 and g(x) = 3x + 9, find (f+g)(x)

(f+g)(x) = f + g = (2x - 6) + (3x + 9) = 5x + 3

(f+g)(x) = f + g = 5x + 3
