Find the value of x in the equation 2(x – 3) 5x = 5(2x 6).

1 answer:

8 0

2(x-3)5x = 5(2x6)
2(x-3)5x = 60
2x -6 x 5x = 60
2x -30x = 60
-28x = 60
28x = -60
x = -15/7
Not sure if I'm correct, but hope it helped

What is the slope intercept form of the line that passes through the point (-2,-18) and has a slope of 1/4

mart [117]

Answer:

y=(1/4)x - 35/2

Step-by-step explanation:

y=mx+b

y=(x/4)+b plug in the slope (m)

-18=(-2/4)+b plug in x and y

b= -17 1/2= -35/2 solve for b

y=(1/4)x - 35/2 plug in m and b into the equation

Find the inverse function of <br><br> y=x^5+9

ollegr [7]

Answer:

$\sqrt[5]{x - 9}$

Step-by-step explanation:

y=x^5+9

To find inverse function make x the subject, first:

y=x^5+9

y - 9 = x^5

x = $\sqrt[5]{y - 9}$

$y^{-1} = \sqrt[5]{x - 9}$

so inverse function of y=x^5+9 is $\sqrt[5]{x - 9}$

A shopkeeper fixed the marked price of his radio to make a profit of 30 percentage. allowing rs 30 as a discount then the profit

dusya [7]

Answer:

rs 200

Step-by-step explanation:

Let cost price = x

At 30% profit; marked price of radio is 30% of x = (100% + 30%) = 130%x

Discount = rs 3%

Profit made = 30

Hence,

Marked price - discount = cost price + 30

130%x - 30 = x + 30

1.3x - 30 = x + 30

1.3x - x = 30 + 30

0.3x = 60

Divide both sides by 0.3

0.3x / 0.3 = 60/ 0.3

x =

1.3x / 1.3 = 60 / 1.3

x = 200

Hence, cost price = rs 200
