please help my friend 99ooooooooooooooooooooooooooooooooooo9ooooo my mjjjkjjidhjubsjuxsvuvjxehxf

Answer: Hope this helps :)

Step-by-step explanation:

a) =Let the boys be x

girls = x-10

so

x + x - 10 = 50

or, 2x = 60

so, x = 30

boys = 30

girls = 30-10 = 20

Therefore, 30 boys participated in the activity.

b) = Let the zilong's stamp be x and miya's stamp be y

so

first

x+y = 40

y = 40-x

now

x - 10 = 2y

x-10 = 2(40-x)

x-10 = 80-2x

or, 3x = 90

so, x = 30

then y = 40-x

        y = 40-30 = 10

Therefore, Zilong had 30 stamps and Miya had 10 stamps before.

Answer:  Choice B

Work Shown:

[tex]-2 \le 2x-4 < 4\\\\-2+4 \le 2x-4+4 < 4+4\ \text{ ... add 4 to all sides}\\\\2 \le 2x < 8\\\\2/2 \le 2x/2 < 8/2\ \text{ ... divide all sides by 2}\\\\1 \le x < 4\\\\[/tex]

This says that x is between 1 and 4; it can equal 1, but it can't equal 4.

To visually represent this, we'll have a closed circle at 1, an open circle at 4, with shading in between these circles. This is represented by graph B.

Answer: 20% lower then A's salary.

Step-by-step explanation:

Step-by-step explanation:

(35-99):99*100 =

(35:99-1)*100 =

35.353535353535-100 = -64.65

Percentage change from 99 to 35 is -64.64% .

Negative sign indicates that the number is decreased from the initial value.

Percentage change : When a number is increased or decreased from its original value is termed as percentage change.

Given, that number changes from 99 to 35.

Formula of percentage change  =  [tex]\frac{Final - Initial}{Initial}[/tex] × [tex]100[/tex]

Final number = 35

Initial number = 99

Substitute the values in the above formula,

Percentage change = [tex]\frac{35 - 99}{99} *100[/tex]

Percentage change = -0.6464 *100

Percentage change = -64.64%

Negative sign indicates that the number is decreased from the initial value.

===================================================

Explanation:

We see that the function passes the horizontal line test. It is impossible to draw a single horizontal line and have that horizontal line cross the curve at multiple points. It's similar to the vertical line test.

Since the curve passes the horizontal line test, that makes it one-to-one. Any y value is paired with a unique x value, and vice versa.

The function is also onto because we can generate any y value output we want. The curve extends forever upward and downward. The range is the set of all real numbers.

Therefore, the function is both one-to-one and onto.
