Answer:
d = √5 ≈ 2.24
Step-by-step explanation:
B is located at (1, 3) and B' is located at (3, 4)
Distance formula:
[tex] d = \sqrt{(xB' - xB)^2 + (yB' - yB)^2}[\tex]
replacing with the coordinates of the points:
[tex] d = \sqrt{(3 - 1)^2 + (4 - 3)^2}[\tex]
[tex] d = \sqrt{4 + 1}[\tex]
d = √5 ≈ 2.24
Answer:
2x - 2y = - 10
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
- 2(x - y) - 10 = 0 ← distribute parenthesis on left side
- 2x + 2y - 10 = 0 ( add 10 to both sides )
- 2x + 2y = 10 ( multiply through by - 1 )
2x - 2y = - 10 ← in standard form
Answer:
x= 12
Step-by-step explanation:
Please see attached picture for full solution.
Marcia can write an expression for the number of candles she will have at the end of "h" hours. She can also write an expression for the number of candles Kevin will have at the end of "h" hours. She can set the two expressions equal to each other and solve for "h", the number of hours until each has the same number of candles.
<span>5h = 4h+7 </span>
<span>h = 7 … subtract 4h from each side </span>
<span>In 7 hours, each will have the same number of candles.</span>
Answer: y=7x
Step-by-step explanation:
To find the line that is parallel to the given line, we know that the slope will stay the same. Parallel lines NEVER touch or cross. Therefore, the slope MUST stay the same. All we have to do is plug in the given point to find the y-intercept.
y=7x+b
0=7(0)+b [multiply]
b=0
Now, we know the equation is y=7x+0 or y=7x.
