Answer:-23/22 or -1.045

Step-by-step explanation:

slope = rise/run

Slope =y2−y1x/2−x1 (The 2's and 1's here should be subscripts sorry)

slope= 12-81 (the y's) divided by 32-(-34)( the x's)

12-81/32-(-34) (Parentehsis just to emphisis the minus a negative number the second coordinate is -32)

slope= -69/66

simplfy to -23/22 or to decimal

slope = -1.045

Let a represent the number of ounces of perfume A. Let b represent the number of ounces of perfume B. Perfume A costs $11 per ou

Julli [10]

Answer:

The system of equations in standard form is equal to

$11a+19b=71$

$a+b=5$

The number of ounces of perfume A is $3\ ounces$

The number of ounces of perfume B is $2\ ounces$

Step-by-step explanation:

Let

a-----> the number of ounces of perfume A

b----> the number of ounces of perfume B

we know that

$11a+19b=71$ -----> equation A

$a+b=5$

$a=5-b$ -----> equation B

substitute equation B in equation A and solve for b

$11(5-b)+19b=71$

$55-11b+19b=71$

$8b=71-55$

$8b=16$

$b=2\ ounces$

Find the value of a

$a=5-b$ -----> $a=5-2=3\ ounces$

Answer:

Step-by-step explanation:

Simplified expression:

$3x^3 -x^3 +5x^3-9x^3$

$2x^3 +5x^3-9x^3$

$7x^3 -9x^3$

$-2x^3$

If x = -1, the value of the expression is:

$-2x^3$

$-2(-1^3)$

$-2(-1)$

$2$

Write an exponential growth function to model the situation. A population of 422,000 increases by 12% each year.

Naya [18.7K]

This is just like working with money in a bank account
that's earning 12% interest.

If the population is 422,000 today, and
' n ' is the number of years after today,
then

Population = 422,000 (1.12)ⁿ .
