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

$y=-11.88x-39.93.$

What is the value of x in the equation 3(2x + 8) = 0? –8 –4 4 8

Flura [38]

3(2x+8)=0

Simplify both sides of the equation.

3(2x+8)=0

(3)(2x)+(3)(8)=0(Distribute)

6x+24=0

Subtract 24 from both sides.

6x+24−24=0−24

6x=−24

Divide both sides by 6.

6x/6 = −24/6

x=−4

Lauren pays $19.99 for a membership fee to an online music store. Lauren buys songs from a new album at the price of $0.99 each.

sdas [7]

The right answer is Option B.

Step-by-step explanation:

Let,

Number of songs = x

Price of 1 song = $0.99

Membership fee = $19.99

Total amount paid = $21.97

According to given statement;

0.99x+19.99=21.97

Subtracting 19.99 from both sides

$0.99x+19.99-19.99=21.97-19.99\\0.99x=1.98$

Dividing both sides by 0.99

$\frac{0.99x}{0.99}=\frac{1.98}{0.99}\\x=2$

Lauren bought 2 songs.

The right answer is Option B.
