Answer:

No, It is not true

Step-by-step explanation:

First of all, we should have a number in the tenths place, and we don't.

Also, in the hundredths place, we should have 9, not 4.

And finally, the answers should be 0.195, not 0.042.

Write an equation that represents the line. (-3,-6) and (2,-2) use exact numbers

Ilia_Sergeevich [38]

Given:

The line passes through (-3,-6) and (2,-2).

To find:

The equation of line.

Solution:

If a line passes through two points $(x_1,y_1)\text{ and }(x_2,y_2)$ , then the equation of line is

$y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)$

The line passes through (-3,-6) and (2,-2). So, the equation of line is

$y-(-6)=\dfrac{-2-(-6)}{2-(-3)}(x-(-3))$

$y+6=\dfrac{-2+6}{2+3}(x+3)$

$y+6=\dfrac{4}{5}(x+3)$

$y+6=\dfrac{4}{5}(x)+\dfrac{4}{5}(3)$

Subtract 6 from both sides.

$y=\dfrac{4}{5}(x)+\dfrac{12}{5}-6$

$y=\dfrac{4}{5}(x)+\dfrac{12-30}{5}$

$y=\dfrac{4}{5}(x)+\dfrac{-18}{5}$

$y=\dfrac{4}{5}(x)-\dfrac{18}{5}$

Therefore, the equation of line is $y=\dfrac{4}{5}(x)-\dfrac{18}{5}$ .

Natalie paid $20.7 for 3 small pizzas and a salad which was $3.

zysi [14]

20.70=3p+3
17.70=3p
$5.90=p
So if you only needed the equation to describe the word problem it is
$20.70=3p+3

If you want to know how much each pizza was it is $5.90; salad $3.00

(-7)-(-44)/22+((-4)*59) with calculation

Pavel [41]

Hi,

$\frac{ ( - 7) - ( - 44)}{22 + (( - 4) \times 59)}$

$\frac{ - 7 - ( - 44)}{22 + (( - 4) \times 59}$

$\frac{ - 7 + 44}{22 + (( - 4) \times 59}$

$\frac{ - 7 + 44}{22 + ( - 236)}$

$\frac{37}{22 + ( - 236)}$

$\frac{37}{22 - 236}$

$\frac{37}{ - 214}$

good look :)
