Ksivusya [100]

Answer:

$17131.50

Step-by-step explanation:

23500 decrease 10% =

23500 × (1 - 10%) = 23500 × (1 - 0.1) = 21150

21150 decrease 10% =

21150 × (1 - 10%) = 21150 × (1 - 0.1) = 19035

19035 decrease 10% =

19035 × (1 - 10%) = 19035 × (1 - 0.1) = 17131.5

9. Write The eQuaTION OF THE LINE THAT Passes THROUGH THE

lara31 [8.8K]

The final equation of line that passes through (9, 0) AND (0, -6) is:

$y=\frac{2}{3}x-6$

Further explanation:

The general form of equation of line is:

$y=mx+b$

Given

(x1,y1) = (9,0)

(x2,y2) = (0, -6)

We have to find the slope first:

$m=\frac{y_2-y_1}{x_2-x_1}\\= \frac{-6-0}{0-9}\\=\frac{-6}{-9}\\=\frac{2}{3}$

Putting the value of slope in general form

$y=\frac{2}{3}x+b$

To find the value of b, we have to put a point in the equation

Putting (9,0) in equation

$0=\frac{2}{3}(9)+b\\0=2*3+b\\0=6+b\\b=-6$

Putting the values of b and m in general form

The final equation of line that passes through (9, 0) AND (0, -6) is:

$y=\frac{2}{3}x-6$

Solve each inequlity 5- 2( 3x-4) -2x < -6x + 4

almond37 [142]

Answer:

x > 9/2

Step-by-step explanation:

don't get scared :) we can isolate the variable easily!

distribute

5 -2( 3x-4) -2x < -6x + 4

5 -6x + 8 - 2x < -6x + 4

-8x + 13 < -6x + 4

+6x -13 +6x -13

-2x < -9

x > 9/2

change the direction of the sign because we divided by a negative

There you go!

I hope this helps (:

A physics class has 50 students. Of these, 10 students are physics majors and 12 students are female. Of the physics majors, t

mylen [45]

Answer:

38% probability that a randomly selected student is female or a physics major.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Physics majors or female

10 physics majors(of which 3 are female).

12 female(the 3 female physics majors have already been counted, so we count 9)

$D = 10 + 9 = 19$

Total outcomes:

50 students, so $T = 50$

Probability

$p = \frac{D}{T} = \frac{19}{50} = 0.38$

38% probability that a randomly selected student is female or a physics major.

How to solve it and understanding it

Yanka [14]

All the values that go into a function

The output values are called the range.

Domain → Function → Range

Example: when the function f(x) = x^2<span>is given the values x = {1,2,3,...} then {1,2,3,...} is the domain.

f(x)=y=x^2
y are range and x are domain</span>
