What is the result of adding these two equations? 6 x + 2 y = − 2 3 x − 2 y = − 5 6x+2y 3x−2y ​ =−2 =−5 ​
stellarik [79]

Answer:

The result gives the equation: 9x = -7

solution:  (-7/9, 4/3)

Step-by-step explanation:

6 x + 2y = − 2

and

3 x − 2y = − 5

add together

6x + 3x + 2y - 2y = -2 + -5

9x + 0 = -7

9x = -7

then x = -7/9

and y = -3x - 1:

y = -3*(-7/9) - 1

y = 7/3 - 1 =  4/3

solution:  (-7/9, 4/3)

-----------------------------------------

6x+2y= -2   and 3x−2y ​ =−5 ​

6x + 3x  + 2y - 2y = -2 + -5

Jennifer and Chelsea each improved their yards by planting rose bushes and geraniums. They bought their supplies from the same s
zvonat [6]

Answer:

$15.00

Step-by-step explanation:

Suppose 1 rose bush costs r dollars,

Suppose 1 geranium costs g dollars.

Here are 2 equations:

1)6r+14g=146

3r+7g=73

2)r+7g=57

r=57-7g

Put 2) in 1)

3(57-7g)+7g=73

171-21g+7g=73

98=14g

g=7

r=8

7+8=$15.00

Hope I helped!

Use the graph below to answer questions 6, 7, and 8.
Andrei [34K]

Answer:

Question 6: the slope is 3

Question 7: 5

Question 8: y=3x+5

Step-by-step explanation:

Using rise over run, You can see that it is 3 in rise and 1 in rise. 3/1 is 3. The y-int is 5 because that is where it touches the y-axis. The formula is y=mx+b where m is slope and b is y-int. Sub the other answers in to find the answer. Hope this helps! Pls mark brainliest!

What is the slope of the line that contains the point (-1,8) and (5,-4) answer.com?
pshichka [43]
THE SLOPE IS -2



if we have the coordinates of two points on a line, we can find the slope with this formula:
s =  \frac{y2 - y1}{x2 -x1}  =  \frac{y1 - y2}{x1 - x2}
so the slope is
\frac{8 - ( - 4)}{ - 1 - 5}  =  \frac{12}{ - 6}  =  - 2
the answer is -2



good luck
