Answer:

9' - 1.29"

Step-by-step explanation:

Total rise = 5' - 2"

Total run = 7' - 6"

1' = 12" = 1 feet = 12 inches

5' = 5 * 12 = 60"

3' = 7 * 12 = 84"

Total rise = 60" + 72" = 62"

Total run = 84" + 6" = 90"

Length of stringer = hypotenus

Hypotenus = √(total rise² + total run²)

Hypotenus = √(62² + 90²)

Hypotenus = 109.28860"

Convwrting back to feet and inches

= 9' - 1.29"

Answer:

The arrangement of the given equation in the slope - intercept form are

$y=-x+4$
$y=2x-5$

Step-by-step explanation:

Given:

x + y = 4 and

y - 2x = -5

Slope - intercept form :

$y=mx+c$

Where,

m is the slope of the line.

c is the y-intercept.

When two points are given say ( x1 , y1 ) and ( x2 , y2) we can remove slope by

Slope,

$m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}$

Intercepts: Where the line cut X axis called X- intercept and where cut Y axis is called Y- intercept.

So, the Slope -intercept form of

x + y = 4 is $y=-x+4$

and

y - 2x = -5 is $y=2x-5$

3. A catering service paid $520 for 10 center pieces and 60 glasses. The guest list grew, requiring an

ELEN [110]

Center piece was $40
Glasses were $2
I used the elimination method. I multiplied everything in the equation that represents the second order by five and subtracted it from the first orders equation. I then solved for y and got that each glass was $2. I then plugged the 2 back into the original equation to find that a centerpiece was $40.
