Answer:
1 + (2 + (-3)) = 0 = (1 + 2) + (−3)
1 × (2 × (−3)) =−6 = (1 × 2) × (−3)
Let the population of Elmore be "X".
Since that the population of Linton is 12 times as great as the population of Elmore, then it is considered to be "12x".
Since that the sum of both Elmore and Linton is 9.646, then "X + 12x = 9464" x+12x is 13x , so it should be "13x = 9464". Now, it is easy to find the population of Elmore which is 9464 / 13 = 742. Since that the population of Linton is 12 times the population of Elmore, then the population of Linton is "742 * 12 = 8904".
Answer:
D
Step-by-step explanation:
If those two functions are the factors of a quadratic, then each of them can be equated to 0 to find the roots. Sometimes the roots are called the zeros.
2x - 5 = 0 Add 5 to both sides
2x - 5 + 5 = 0 + 5 Combine
2x = 5 Divide both sides by 2
2x/2 = 5/2
x = 5/2
You don't really have to find the other factor's 0 point. There is only 1 option that makes x = 5/2. On a test, it is important to take short cuts and save time. I'll find the other root anyway because this is not a test.
3x + 4 = 0 Subtract 4 from both sides
3x + 4-4 = 0 - 4 Combine
3x = - 4 Divide both sides by 3
3x/3 = - 4/3
x = - 4/3
Answer:
The coordinates of point X are (-11/2, 5/2)
Step-by-step explanation:
To find the coordinates of X , we shall apply the midpoint formula;
Mathematically, that would be;
(x , y) = (x1 + x2)/2 , (y1 + y2)/2
From the question
x1 = -3 , x2 = -8
y1 = 1 , y2 = 4
So substituting these values, we have;
(x ,y) = (-3-8)/2, (1 + 4)/2
(x ,y) = -11/2, 5/2
You would set this up as Part÷Whole=Percent÷100
Part=117
Whole= X
Percent=78
117÷X=78÷100
Set these up as fractions and cross multiply. You will get 117×100=78X
117×100=11,700
Divide both sides by 78 and you get x=150
