My grade is a 77%, if i get a 0% on a paper worth 30% of my grade, what will my grade be now??
blsea [12.9K]
Grade=Paper+Other
Grade=(Grade_{paper}\times Value_{paper})+(Grade_{other}\times Value_{other})
Grade=(0 \times 30\%)+(77\% \times (1-30\%))
Grade=(0 \times 30\%)+(77\% \times 70\%)
Grade=0+53.9\%
Grade=53.9\%

Which of the following systems of inequalities would produce the region
Mnenie [13.5K]

Answer:

y > x + 1 ; y ≤ 10 ; x ≥ 0

Step-by-step explanation:

First, we need to get the equation of the straight line. The equation of the straight line is expressed as y = mx+c

m is the slope

c is the y-intercept

Using the coordinate points (0, 1) and (1,2)

m = (2-1)/(1-0)

m = 1/1 = 1

y-intercept c = 1 (the point where the line cuts the y-axis)

Substitute;

Since y = mx+c, then y = 1x + 1

y = x+1

Since the line is a broken line and shaded above, then y > x+1

Also, the point shaded on the graph indicates y ≤ 10 ; x ≥ 0
