Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{2z - 5y}}}}}

Step-by-step explanation:

\sf{ - ( - 2z + 5y)}

Distribute negative ( - ) sign through the parentheses

\sf{( - ) \times ( - 2z)  + ( - ) \times (5y)}

\dashrightarrow{ \sf{2z   + ( - 5y)}}

\dashrightarrow{ \sf{2z - 5y}}

Hope I helped!

Best regards! :D

1.) What is slope and how is it determined from an graph?
Daniel [21]

1) Slope tell about the steepness of the line.

To find slope we look at the rise and run between 2 points.


attached the graph of line with slope


slope = \frac{change in y values ( rise)}{change in x value (run)}

= \frac{2}{1}

So slope = 2

2) we have x and y intercepts


x intercept is the point where the line crosses x axis


x intercept at x= 3


y intercept is the point where the line crosses y axis


y intercept at y= 6

3) Linear equation is y= 3x+2

function is f(x) = 3x+2

We can graph it using slope and y intercept


In f(x)= 3x + 2 , slope =3 and y intercept = 2


slope = 3, rise = 3 and run =1


The graph of f(x)= 3x+2 is attached below.

If y=15 when x=5, find y when x=7, given that y varies directly with x.
Oxana [17]

Answer:

when x = 7, y = 21

Step-by-step explanation:

This is about direct variation. If y varies directly with x, then there is a constant  factor of variation, k. The constant of variation can be found by ʸ⁄ₓ

k = ʸ⁄ₓ

k = ¹⁵⁄₅ = 3

Now that we have found k, we simply multiply x by it to find y (this is because y is directly proportional to x). We plug in our x = 7 to find y at this point.

y = 3x

y = 3(7)

y = 21
