Answer:

see below

Step-by-step explanation:

Add the students who passed french, german, both

add 17+19+11 = 47

Subtract this from 55 to get b

b = 55-47 =8

b =8

P( passed french and german)

= number that passed french and german / total

= 19/55

P( french or german) =

= number that passed french or german / total

= (17+11)/55 =28/55

Simplify (4xy-2x)+(2x^2+8x)

devlian [24]

Answer: 4xy+6x+2x^2

Step-by-step explanation:

4xy-2x+2x^2+8x

we can combine the terms that only have an x (Ax for any number A)

in this case that's -2x and 8x

-2x+8x=6x

the other things can't be combined

thus you end up with

4xy+6x+2x^2

24x^5-8x^4+12x^3-4x^2 / 4x^2

Margaret [11]

Answer:

The detailed process of simplification is :

Step-by-step explanation:

$\frac{24x^{5} - 8x^{4} + 12x^{3} - 4x^{2} }{4x^{2} }$

= $\frac{24x^{5} }{4x^{2} }$ - $\frac{8x^{4} }{4x^{2} }$ + $\frac{12x^{3} }{4x^{2} }$ - $\frac{4x^{2} }{4x^{2} }$ ..........................separate the terms

= 6 $x^{5-2}$ - 2 $x^{4-2}$ + 3 $x^{3-2}$ - 1 ................ subtract the power of x from denominator

= 6 $x^{3}$ - 2 $x^{2}$ + 3 $x$ -1

= 2 $x^{2}$ ( 3 $x$ -1 ) + (3 $x$ -1 )................................... Take (3 $x$ -1 ) common in (6 $x^{3}$ - 2 $x^{2}$ )

= (3 $x$ -1 ) (2 $x^{2}$ +1) .......................................Take (3 $x$ -1 ) common in whole equation

Write the equation of the line that passes through the points (7,-6) and (0,2). Put

Alex

Answer:

$y+6=\frac{-8}{7} (x-7)$

Step-by-step explanation:

To find the slope of the equation use $\frac{y_2-y_1}{x_2-x_1}$ .

So, $\frac{-6-2}{7-0}$ = $\frac{-8}{7}$ . Now we can use our slope and any of the two points to write in point-slope form, which is $y-y_1=m(x-x_1)$ . Using the point (7,-6), the formula will give $y+6=\frac{-8}{7} (x-7)$ .

To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
