jok3333 [9.3K]

Answer:

(1,4)

Step-by-step explanation:

if~(x,y)~is~mid~point~of~(x_{1},y_{1})~and~ (x_{2},y_{2}~then\\x=\frac{x_{1}+x_{2}}{2} \\y=\frac{y_{1}+y_{2}}{2} \\x=\frac{5-3}{2} =\frac{2}{2}=1\\y=\frac{7+1}{2} =\frac{8}{2} =4

(x,y)→(1,4)

William estimated √140 by placing a point on the number line below. Which is true about his estimate? please guys I need this du
garik1379 [7]

Answer:

Step-by-step explanation:

Familiarize yourself with perfect squares in the neighborhood of 140:

10^2 = 100

11^2 = 121

12^2 = 144

Note that 140 is much closer to the perfect square than it is to the perfect square 121.  The value of √140 must lie closer to 12 than to 11.

Place a point on the number line about 3/4 of the way from 11 to 12.

Which line is parallel to y= -52 + 6 and passes through (4, -2)?
Alexxandr [17]

Answer:

\[y=-5x+18\]

Step-by-step explanation:

Given that the line is parallel to \[y = -5x + 6\]

Hence the slope of the line is given by -5

Hence the equation of the required line can be represented by \[y = -5x + c\]

This line passes through (4,-2). Substituting:

\[-2 = -5 * 4 + c\]

=> \[-2 = -20 + c\]

=> c = 20-2 = 18

So the required equation of the line is given by : \[y = -5x + 18\]

From the given options, option 3 is the correct one.
