Answer:
The graph of f(x) = x2 is shown at right. ... The vertex for the quadratic equation f(x) = a(x h)2 + k is the point.
X intercept is where the line crosses the x axis or where y=0
y intercept is where the line crosses the y axis or where x=0
so
6x-3y=-6
x intercept
y=0
6x-3(0)=-6
6x=-6
x=-1
x intercept at x=-1 or the point (-1,0)
y intercept
x=0
6(0)-3y=-6
-3y=-6
y=2
y intercept at y=2 or the point (0,2)
X-y=50 and 2x=3y
x=y+50 so 2(y+50) = 3y
2y+100=3y
y=100
x-100=50
x=150
so our numbers are 150 and 100
150-100=50 and 150 is 3*50 and 100 is 2*50 so fits all requirements!
hope this helps you! thank you!
Answer:
x=200
Step-by-step explanation:
let 'x' represent the total number of students
0.40x of the students voted for Gerardo
0.35x of the students voted for Leandro
0.25x of the students voted for Juju
70 students voted for Leandro:
0.35x = 70
by solving we find:
x = 200 students
