To solve this problem, we will use the distributive property.
3/4(x + 9) = 15
3/4x + 6.75 = 15
Now we will subtract 6.75 from both sides of the equation.
3/4x = 8.25
To get rid of the fraction, we will multiply 8.25 by 4, then divide it by 3.
3/4x • 4 ÷ 3 = 8.25 • 4 ÷ 3
x = 11
Another way to do this would be to divide 3 by 4 and write .75x, then divide .75 into 8.25.  It would still get us 11.
In this equation, x is equal to 11.

Which of the following is the solution to the differentiable equation dy/dx=4x/y, where Y(2)=-2
aliya0001 [1]

First we'll substitute \frac{dy}{dx} with y'

y'=\frac{4x}{y}

Then we can separate this.

yy'=4x

Then we'll solve this.

yy'=4x: \frac{y^2}{2}=2x^2+c_1

\frac{y^2}{2}=2x^2-6

y=2\sqrt{x^2-3},y=-2\sqrt{x^2-3}

Then we'll plug in to find the extraneous solutions (if any)

y=-2\sqrt{x^2-3}

Consider the following model:
SSSSS [86.1K]

Answer:

a. 3

Step-by-step explanation:

An independent variable is the variable that is changed in an experiment to test its effects on the dependent variable. i.e. inputs

A dependent variable is the variable being tested, measured or predicted in an experiment. I.e a outcome

In this case, the the effects of the amount tutors are paid a week before exam, the amount of sleep before exam and the number of study hours are input variables to determine or predict a students score in exam

The independent variables are;

x1 =represents the amount paid to a tutor (in dollars) in the week before the exam

x2 = represents the number of hours of sleep in the week before the exam

x3 = number of study hours in the week before the exam

The dependent variable is the exam score

B0, B1, B2,B3, B4 are coefficients

the sum of kate's age and her mother's age is 52. Kates mother is 20 years older than kate. how old is each
Anna35 [415]
<span>The sum of Kate age and her mother's age is 52, so 
K + M = 52 
Kate's mother is 20 years older then Kate, so 
M = 20 + K 
How old is each person? 
Since M = 20 + K, substitute it into the first equation, that is, replace M with 20 + K 

So, K + (20 + K) = 52 
K + 20 + K = 52 
2K + 20 = 52 
Subtract 20 from both sides: 
2K = 52 - 20 
2K = 32 
divide both sides by 2 to get 
K = 16 
Now we can find M, since M = 20 + K = 20 + 16 = 36 
Kate is 16 years old and her mother is 36 years old.
Hope this helps!!1</span>
