Let’s isolate y using inverse operations to convert this into slope intercept form. Choose the equivalent one after that!

Hi there! The answer is D.

To find our solution we must isolate y.

$2x + 5y = - 2$
First subtract 2x from both sides.

$5y = - 2x - 2$
Now we can divide both sides of the equation by 5.

$y = - \frac{2}{5} x - \frac{2}{5}$
Therefore, the answer is D. y=-2/5x-2/5

const2013 [10]

Answer:

Step-by-step explanation:

let x be apple juice and y be orange juice

12 = x + y

x = 12 - y

15 = 1x + 1.5y

x = 15 - 1.5y

set the equations as equal

12 - y = 15 - 1.5y

solve for y

12 + .5y = 15

.5y = 3

y = 6, you bought 6 bottles of orange juice

so, 12 = x + 6 , x = 6 , you bought 6 bottles of apple juice

8. rajis annual salary ranges from $25 325 in the 1st year to $34 445 in the 7th year. The salaries in this range form an arithm

-Dominant- [34]

Answer:

a) $1520

b) $S_7 =$ $209195

Step-by-step explanation:

The range of salaries forms an arithmetic sequence with the first term as 25325 and its 7th term as 34445:

a) The raise the person can get each year is the common difference of the progression, d.

The nth term of an arithmetic progression is given generally as:

$a_n = a + (n - 1)d$

where a = first term = 25325

d = common difference

Therefore, the 7th term (34445) will be:

34445 = 25325 + (7 - 1)d

34445 = 25325 + 6d

=> 6d = 34445 - 25325 = 9120

d = 9120 / 6 = $1520

Therefore, the raise the person gets each year (common difference) is $1520.

b) The total amount the person will earn after 7 years is the sum of the salaries of all 7 yeas.

The sum of an arithmetic progression up to the nth term is given as:

$S_n = \frac{n}{2}(2a + (n - 1)d)\\ \\$

Therefore, the sum of the person's salary for the 7 years is:

$S_7 = \frac{7}{2}(2 * 25325 + (7 - 1)1520)\\ \\S_7 = 3.5 (50650 + 6(1520))\\\\S_7 = 3.5 (50650 + 9120)\\\\S_7 = 3.5 * 59770\\$

$S_7 =$ $209195

That is the total amount of salary after 7 years
