A bag contains green marbles and blue marbles, 55 in total. The number of green marbles is 7 more than 5 times the number of blu

MrRissso [65]

Answer:

Step-by-step explanation:

Total marbles in bag= 55

Given that

The number of green marbles is 7 more than 5 times the number of blue marbles.

Let green marble be x

And blue marble be y

Therefore,

Green=seven more than 5 times blue

Green=7+5timesblue

x=7+5y. Equation 1

Also the sum of the marbles is 55

x+y=55. Equation 2

Substitute equation 1 into 2

7+5y+y=55

7+6y=55

6y=55-7

6y=48

y=48/6

y=8

From equation 2

x+y=55

Then, x=55-y

x=55-8

x=47

Then, green marbles is 47.

Also, Blue marbles is 8

8x + 2y =16<br>standard form <br>1) m=<br>2 y - intercept x - intercept <br>

mestny [16]

Answer:

m=-4

y-intercept=8

x-intercept=2

Step-by-step explanation:

Please see attachment.

y-intercept=8

The y-intercept is where the line crosses the y-axis.

x-intercept=2

The x-intercept is where the line crosses the x-axis.

m=-4

If you do not know how to find slope by looking at graph, use slope formula.

(y2-y1)/(x2-x1)

Choose 2 points. You may use the x and y intercepts.

(2,0) and (0,8)

(8-0)/(0-2)=8/-2=-4

Hope this helps!
