About 96.47 so your answer is D
The y intercept (b) is where is crosses the y axis = 5
The x intercept is where is crosses the x axis = 4
The slope is rise over run or y2 - y1/x2 - x1
m = 0 - 5/4 - 0
m = -5/4
y = mx +b
y = -5/4x + 5
First Equation
STEP 1: Move the variable to the right side and change its sign
3x=8-y
STEP 2: Divide both sides of the equation by 3
x=8/3 - y/3
STEP 3: Write all numerators above the common denominator
x=8-y/3
THE FINAL ANSWER IS:
x=8-y/3
Second Equation
STEP 1: Move variable to the right side and change its sign
-x= -10+2y
STEP 2: Change the signs on both sides of the equation
x=10-2y
THE FINAL ANSWER IS:
x=10-2y
Hello! :)
P (a or b) means
P (a+b)
So the blue side and the red side of the diagram have students so add them up:
3+2=5
Then the ratio
blue and red/total number of students
5/10
(10 students)
So simplify:
1/2
Hope I helped and answered in time!
Good luck!
