Write equations to solve these problems

dangina [55]

Answer:

Step-by-step explanation:

a) 60 = 50x

x = 60 / 50 = 1.20

1.20(100) = 120%

b 50 = 60x

x = 50/60 = 0.83333....

0.83333(100) = 83.333... % or 83⅓%

Need help with this math problem

In the figure, Blueline is Line AB and Redline is target line.

You can see that the target line does not pass through (18,-8)

Step-by-step explanation:

In the figure, Blueline is Line AB and Redline is target line.

You can see that the target line does not pass through (18,-8)

Taking a bottom-left corner of the graph as (0,0)

Given Line AB,

Point A is located as (4,9)

Point B is located as (16,1)

The slope of AB is

$=\frac{Y1-Y2}{X1-X2}$

$=\frac{9-1}{4-16}$

$=\frac{8}{-12}$

$=\frac{-2}{3}$

The question says " Draw a line passes through C(13,12) and parallel to Line AB "

Now, Let the equation of the target line is y=mx + c

Where m=slope and c is the y-intercept

The target line is parallel to the line AB

The slope of the Target line = The slope of the Line AB $=\frac{-2}{3}$

m= $=\frac{-2}{3}$

We can write, the equation of the target line is

$y=\frac{-2}{3}x + c$

Also, the Target line is passing through C(13,12)

Point C satisfies the equation

$y=\frac{-2}{3}x + c$

$12=\frac{-2}{3}13 + c$

$12=\frac{-26}{3} + c$

$12+\frac{26}{3}=c$

$c= 12+\frac{26}{3}$

$c= \frac{62}{3}$

Replacing the value

the equation of the target line is

$y=\frac{-2}{3}x + c$

$y=\frac{-2}{3}x + \frac{62}{3}$

$3y= -2x + 62$

It is also asked that if a line is extended , would it passes through the (18,-8)?

If a line passes through the point (18-,8) then, that point must satisfy the equation of a line

the equation of the target line is $3y= -2x + 62$

$3(-8)= -2(18) + 62$

$(-24)= (-36) + 62$

$(-24)= 26$

Left land side is not equal to right hand side.

Therefore. a line does not pass through the point (18,-8)

Miguel paid a total of $12,000 for stock that was $8 per share. If he sold all his shares for $15,000, how much profit on each s

Scorpion4ik [409]

If you would like to know how much profit on each share did he make, you can calculate this using the following steps:

$12,000 / $8 = 1,500 shares

$15,000 / 1,500 shares = $10 per share

x% of $8 is $10
x/100 * 8 = 10 /*100/8
x = 10 * 100 / 8
x = 125%

125% - 100% = 25%

Miguel made 25% ($2) profit on each share.

What point is plotted on the graph? (9, 8) (9, 9) (8, 8) (8, 9)

zhannawk [14.2K]

Answer:

It'd help to show the graph but, count out how far it goes right, than count up how far it goes up, the first number is x, the second number is y
