Answer:

Step-by-step explanation:

Any multiple of the given equation is also a dependent linear equation

From the equation

-5x+7y=2

Multiplying all through by any number, say 2

2(-5x)+2(7y)=2(2)

-10x+14y=4 is a dependent linear equation for -5x+7y=2

If you don't fancy using a multiple, you can write the gradient equation y=mx+c

-5x+7y=2

7y=5x+2

Dividing all through by 7 gives the equation as

y=5x/7 + 2/7

-5 = -y - 3x<br> Write the equation in slope-intercept form. Please help me. :)

DaniilM [7]

Answer:

y = -3x + 5

Step-by-step explanation:

You want it in y = mx + b form

-5 = -y - 3x

Add y to both sides

-5 + y = -y + y - 3x

-5 + y = -3x

Add 5 to both sides

- 5 + 5 + y = -3x + 5

y = -3x + 5

Gina is putting candy into bags for her students.She has 93 students throughout the day and plans to put 0.35 pounds of candy in

Scilla [17]

Answer: There are 11 bags approximately.

Explanation:

Since we have given that

Number of students = 93

Amount of candy put into each bag = 0.35 pounds

Amount of candy she will needed altogether is given by

$0.35\times 93=32.55\ pounds$

Now, we have given that

Candy comes in 4 pound bags ,

So,

Number of full bags she would need to purchase is given by

$\frac{4}{0.35}=11.42=11 \ bags$

Hence, there are 11 bags approximately.
