So this can be solve by establish two equation:
let x be age of montell
y be tha age of her mom
for the first equation (<span>Montell is 30 years)</span>:
x = y - 30
second equation ( in 5 years )
x + 5 = ( y + 5 ) ( 1/3)
solving the equation simultaneously
x = 10 years old
y = 40 years old
Answer:
<h2>y = 6x + 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:

<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the slope <em>m = 6</em>, and the y-intercept <em>b = 2</em>.
Substitute:

Answer:
9 Model As.
Step-by-step explanation:
Let A represent Press A and let B represent Press B.
So, they own 14 total presses. This means that:

They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:

Substitute this into the second equation: "

First, we can divide everything by 5 to simplify things:

Distribute the left:

Combine like terms:

Subtract 196 from both sides:

Divide both sides by -3

So, the company has 5 Model B presses.
Which means that the company has 14-5 or 9 Model A presses.
And we're done!
Answer:
Use the method for solving Bernoulli equations to solve the following differential equation.
StartFraction dy Over dx EndFraction plus StartFraction y Over x minus 9 EndFraction equals 5 (x minus 9 )y Superscript one half
