When you are adding a positive number we would go right but -9 isn’t a positive it’s a negative so we would go left on the number line

Answer:

-12

Step-by-step explanation:

1. Create an Equation

-3-9

2. Solve

-3-9 <=== subtract -3 and -9 together to get your answer

-12

3. Check

-12+3 <=== create this equation or this one ===> -12+9 to check if we calculated correctly

-12+3= -9 -12+9= -3

this shows the answer is corrrect

Review the work showing the first few steps in writing a partial fraction decomposition.

allochka39001 [22]

Answer:

8/(x + 2) - 4/(x + 6)

Step-by-step explanation:

4x + 40 = Ax + 6A + Bx + 2B

Equating coefficients of x

4 = A + B (1)

Equating constant terms:

40 = 6A + 2B (2)

Multiply equation (1) by -2:

-8 = -2A - 2B .. (3)

Add (2) and (3):

32 = 4A

A = 32/4

A = 8.

4 = 8 + B

B = 4 - 8

B = -4.

If log10(x^{2}y^{3})=7 and log10 (x/y)=1 , then x=__ and y= __

yuradex [85]

Answer:

$x=100$

$y=10$

Step-by-step explanation:

we are given

$log_1_0(\frac{x}{y})=1$

Firstly, we will get rid of log

so, we will take exponent over 10 on both sides

$10^{log_1_0(\frac{x}{y})}=10^{1}$

now, we can simplify it

$\frac{x}{y}=10$

now, we can solve for x

$x=10y$

we are given

$log_1_0(x^2y^3)=7$

Firstly, we will get rid of log

so, we will take exponent of 10 on both sides

$10^{log_1_0(x^2y^3)}=10^7$

$x^2y^3=10^7$

now, we can plug back x from first equation

$(10y)^2y^3=10^7$

now, we can solve for y

$100y^5=10000000$

$\frac{100y^5}{100}=\frac{10000000}{100}$

$y^5=100000$

now, we can take radical 5

$y=\sqrt[5]{100000}$

$y=10$

now, we can find x

$x=10\times 10$

$x=100$

So, solution is

$x=100$

$y=10$
