Answer:

P(7, -7)

Step-by-step explanation:

Xp = 6+ ⅓(9-6)= 6+ ⅓(3)=6+1 =7

Yp = -10 + ⅓(-1+10)= -10+⅓(9)= -10+3=-7

=> P (7, -7)

Does the line passing through the points (−1,−5) and (2,1) intersect the line passing through the points (−1,−6) and (1,2)?

Serggg [28]

Answer:

Yes

Step-by-step explanation:

As long as the slopes of these two lines are not the same, they will intersect.

Given two points on a line, we can find the slope by taking the difference in the y coordinates and dividing it by the difference in the x coordinates.

Slope of 1st line: $\frac{-5-1}{-1-2} =\frac{-6}{-3} =\frac{1}{2}$

Slope of 2nd line: $\frac{-6-2}{-1-1} =\frac{-8}{-2}=4$

The slopes are not equal, therefore the lines intersect.

jeka57 [31]

Answer:

$5.91430991*10^1^5$

Step-by-step explanation:

$4598\left(345+892\cdot \:231\right)\cdot \:5617\cdot \frac{1232+987}{2}\\=4598\cdot \:5617\cdot \frac{1232+987}{2}\left(345+206052\right)\\=4598\cdot \:5617\cdot \frac{2219}{2}\left(345+206052\right)\\=4598\cdot \:206397\cdot \:5617\cdot \frac{2219}{2}\\=\frac{2219\cdot \:4598\cdot \:206397\cdot \:5617}{2}\\=\frac{1.18286\dots E16}{2}\\=5.91431e15$

Perform the indicated operation. (-10) - (-4)

trapecia [35]

It would be a negative six ,-6, because if you draw a number line and on one side there are positive numbers on the right and on the left there are negative numbers, you would have to go up to ten on both sides one being positive and the other being negative.You will then go on the negative side and move four spaces to the right from the -10 and you will get a -6.
