This may be one of those questions that could take
more paper to ask than to answer.
Line-1 goes through (-4, 8) and (4,6) .
Its slope is (difference in 'y') / (difference in 'x')
Dif in 'y' = (6 - 8) = 2
Dif in 'x' = (4 - -4) = 8
Slope of Line-1 = 2/8 or 1/4
Line-2 goes through (-1, 1) and (3, 5)
Its slope is (difference in 'y') / (difference in 'x')
Dif in 'y' = (5 - 1) = 4
Dif in 'x' = (3 - -1) = 4
Slope of Line-2 = 4/4 = 1
Slope of Line-1 = 1/4
Slope of Line-2 = 4
The slopes of the lines are different.
They can't be parallel, and they can't be the same line.
They must intersect in one point, and only one point.
That means the pair of equations has exactly one (1) solution.
The answer is 13 minus 3 equals 10
Answer:
7
Step-by-step explanation:
There are 7 days in a week, and she sent 49 messages by the end of the week. Assuming that she sent the same number of messages each day, we would take the number of messages and divide it by the number of days, 49 and 7. 49 divided by 7 is 7. She sent 7 messages each day!
Hope this helps, brainliest always appreciated haha
12 x 4.89 = 50.68
17 x 4.72 = 80.24
15 x 5.09 = 76.35
50.68 + 80.24 + 76.35 = $207.27
