Answer:
The answer is A) 2x + y = 6
Step-by-step explanation:
Since the first line has a slope of -2, we know that the second does as well. We know this because parallel lines have the same slope. Now we can use that slope along with the point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 2 = -2(x - 2)
y - 2 = -2x + 4
y = -2x + 6
In this case, to find an equation that is similar, we could put it into standard for.
y = -2x + 6
2x + y = 6
This is answer A
Answer: $10
Step-by-step explanation:
Let's analize the information given: We know that she had $94 to spend on 8 books and after buying these books she had $14. So, we need to calculate the amount of money she spent. Subtract $94 and $14:
Then, to calculate the cost of each book, we need to divide the "Total spent" by 8:
Answer:A runner ran 20 miles in 150 minutes. If she runs at that speed,. How long would it take her to run 6 miles? ... How fast is she running in miles per hour? ... experience in reasoning with equivalent ratios and unit rates from both sides of the ratio.
Step-by-step explanation:
Answer:
5/9 of 90 = (5/9)(90) = 50
Step-by-step explanation:
The point slope form of a line is written as y - y1 = m(x -x1)
Where m is the slope and x1 and y1 are the points on the line.
You are told the slope is 3 and the point is (2,-1/2)
x1 is 2 and y1 is -1/2
Replace those in the equation to get:
y- (-1/2) = 3(x-2)
Simplify to get the final answer:
y + 1/2 = 3(x-2)
