Answer:
-2y +2
Step-by-step explanation:
(x - y + 1) - (x + y - 1)
Distribute the minus sign
(x - y + 1) - x - y + 1
Combine like terms
x-x -y-y +1+1
-2y +2
Answer:
y = x - 13
Step-by-step explanation:
Given parameters:
Slope of the line = 1
Coordinate = (18, 15)
Unknown:
Equation of the line in slope-intercept format = ?
Solution:
The equation of a line is expressed as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
Now, sine x = 18 and y = 5, let us find c;
5 = 1(18) + c
5 = 18 + c
c = -13;
The equation of the line is;
y = 1(x) + (-13)
y = x - 13
Answer:
Option B, x = 20
Step-by-step explanation:
<u>Step 1: Make an equation</u>
The values of 65 degrees and (3x + 5) are equal.
65 = 3x + 5
<u>Step 2: Subtract 5 from both sides</u>
65 - 5 = 3x + 5 - 5
60 = 3x
<u>Step 3: Divide both sides by 3</u>
60 / 3 = 3x / 3
<em>20 = x</em>

Answer: Option B, x = 20
Answer:
Step-by-step explanation:
The team made 2,061.50 at the first game and 2,000.00 at the second game. Because 2,000.00 would be 61.50 less than the amount made at the first game. You can check it by adding 2,061.50 + 2,000.00 which equals $4,061.50.
