Find the line y=a+bxy=a+bx which best approximates the data points (−3,−5),(−2,−17),(−1,−26),(1,−51),(2,−65).

dimaraw [331]

Answer:

y=-11.88x-39.93

Step-by-step explanation:

Plot the data

$\begin{array}{cc}x&y\\-3&-5\\-2&-17\\-1&-26\\1&-51\\2&-65\end{array}$

on the coordinate plane using graphing calculator. Then use linear approximation y=ax+b and determine that a=-11.88, b=-39.93.

The line that best fits these data is

$y=-11.88x-39.93.$

Evaluate the expression 3 4/5x-2 1/2 for x =-10

lyudmila [28]

Answer:

The value of given expression for x = - 10 is - 81

Step-by-step explanation:

Given expression as :

3 $\frac{4}{5}$ x - 2 $\frac{1}{2}$

Or, 3 + $\frac{4}{5}$ x - 2 - $\frac{1}{2}$

Or, $\frac{19}{5}$ x - $\frac{5}{2}$

or, $\frac{38 x - 25}{5}$

Now for x = - 10

$\frac{38\times (- 10) - 25}{5}$

Or, ${38\times (- 2) - 5}$

∴ - 76 - 5

Or, - 81

Hence The value of given expression for x = - 10 is - 81 Answer
