18 is not a perfect square
Answer:
Step-by-step explanation:
let x = the number of votes of the first person
winner = x + 4000
x+ x+4000 = 6000
2x=2000
x=1000
first person = x = 1000
winner = x+4000 = 5000
The winner got 5000 votes
Answer:
<em>Correct choice: B</em>
Step-by-step explanation:
<u>System of non-linear equations</u>
It's given the following system of equations:
We'll use the substitution method. Substituting y from the first equation into the second equation, we have:
Moving all terms to the left side:
Simplifying:
Factoring:
There are two solutions:
x=-4, x=2
The first solution gives a value for y:
y=-4+13=9
First solution: (-4,9)
The second solution gives a value for y:
y=2+13=15
Second solution: (2,15)
Correct choice: B
The movie will last 2 hours and 15 minutes.
Subtract 9:30 - 7:15
You have to use Point Slope Form...
ABOUT POINT SLOPE FORM:
- y - Y1 = m (x - X1)
- Y1 & X1 is a point on the line
- The form allows you to identify the slope & the point on the line
ABOUT PROBLEM:
- Since -1 is the slope, that means it represents m in the point slope formula
- -2 represents X1 in the point slope formula
- -1 represents Y1 in the point slope formula
y - Y1 = m (x - X1)
y - -1 = -1 (x - -2) --- In Point Slope Form
Hope this helps you!!! :)
