Answer:

1/7 + 2 4/7 = 2 5/7

Step-by-step explanation:

Leave 2 alone since there are no other whole numbers to add to it.

Then combine the fractions

1/7 + 4/7 = 5/7

So we have 2 5/7

What is the equation of the line that passes through the point (-5,5)and has a slope of -1
erastova [34]

Answer:

<h2>           y = - x  </h2>

Step-by-step explanation:

The point-slope form of the equation is y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope:

m = -1

(-5, 5)    ⇒   x₀ = -5,  y₀ = 5

The point-slope form of the equation:

y - 5 = -1(x + 5)

So:

y - 5 = -x - 5         {add 5 to both sides}

y = -x             ←  the slope-intercept form of the equation

Please please, please
Masja [62]

The production of health drink cans at a warehouse can be represented by the equation below, where x represents the hours of production, and y the total supply of items in the warehouse, in hundreds.

Which of the following graphs represents this situation?

the equation is y= 3/5x+2

I drew the graph.

3/5 is the slope, and 2 is the y-intercept. So you start at (0,2), and go up 3 units, then right 5.

hope it helps

X^2+20x+c find the value of c that makes a perfect square trinomial
ollegr [7]

Answer:

This means c=100. The factored form is (x+10)^2.

Step-by-step explanation:

A perfect square is a trinomial that factors into the form (x+a)^2. To find the value of C to finish the perfect square divide 20 by 2 and square it.

20/2 = 10

10*10=100

This means c=100. The factored form is (x+10)^2.
