Write an equation that shows the equivalency between meters and gigameters.

Anastasy [175]

Below is an equation that shows the equivalency between meters andGigameters:

$10 ^{9} m = 1 Gm$

The conversion factor should be used to convert from meters toGigameters should be:

$\frac{1 Gm}{10 ^{9} m }$

Kyle wants to find the equation of the line that passes through the points (1, –7) and (–1, 1) .

Harrizon [31]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

There are two points as follows:

$(1,-7)\ and\ (-1,1)$

As we know the formula for "Two point slope form":

$m=\frac{y_2-y_1}{x_2-x_1}$

Now, we put the values in the above equation ,

$m=\frac{1+7}{-1-1}\\\\m=\frac{8}{-2}\\\\m=-4$

Now, we use this form " $y=mx+b$ "

So,

$-7=-4(1)+b\\\\-7+4=b\\\\-3=b$

Hence, Option 'c' is correct.

Will mark brainly! :)

rewona [7]

Answer:

Y = 0

Step-by-step explanation:

Both functions have

maximum of $\frac{2}{3}$

minimum of - $\frac{2}{3}$

midline is then the average of these

( $\frac{2}{3}$ - $\frac{2}{3}$ ) ÷ 2 = 0 ÷ 2 = 0

midline has equation y = 0 ( that is the x- axis )

Dy If y - 2x+3 then 3x+29 dx

Sergeu [11.5K]

Answer:

$y'=\frac{-5}{(3x+2)^2}$

Step-by-step explanation:

Step 1: Write equation

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

Step 2: Find derivative

Quotient Rule: $y'=\frac{(3x+2)(2)-(3)(2x+3)}{(3x+2)^2}$
Simplify: $y'=\frac{(6x+4)-(6x+9)}{(3x+2)^2}$
Simplify: $y'=\frac{-5}{(3x+2)^2}$
