20000 is 1/10 of what number

1 answer:

7 0

I will write your question as an equation:

20 000 =1/10*x

and we need to find the x. For this, we multiply both sides by 10:

200 000 =x

so the answer is 200 000

12y(5y-7)(4y+9)=0 please show step by step to solve

Tcecarenko [31]

Answer:

y=0,y=7/5,y=-9/4

Step-by-step explanation:

12y(5y-7)(4y+9)=0

Using the zero product property

12y =0 (5y-7) =0 (4y+9)=0

12y/12 =0/12 5y-7 +7 =0+7 4y+9-9=0-9

y =0 5y = 7 4y = -9

5y/5 = 7/5 4y/4 =-9/4

y = 7/5 y =-9/4

Complete the slope-intercept form of the linear equation that represents the relationship in the table.

nevsk [136]

According to the given table, the slope-intercept equation of the line is given by:

$y = -2x + 1$

The equation of a line, in slope-intercept form, is given by:

$y = mx + b$

In which:

The slope is m.

The intercept is b.

In this problem, we are given two points, (3,-5) and (-2,5).

The slope is given by change in y divided by change in x, hence:

$m = \frac{5 - (-5)}{-2 - 3} = -2$

Hence:

$y = -2x + b$

Point (3,-5) means that when $x = 3, y = -5$ , which is used to find b.

$y = -2x + b$

$-5 = -2(3) + b$

$b = 1$

Hence, the equation of the line is:

$y = -2x + 1$
