That’s true. If I were to explain why it would be restating the true or false question.

136+12x=-4(1-2x) simplify

lawyer [7]

Answer:

x=-35

Step-by-step explanation:

136+12x=-4(1-2x)

136+12x=-4+8x

+4 +4

140+12x-12x=8x-12x

140/-4=-4x/-4

x= -35

What is the system of inequalities associated with the following graph?

slamgirl [31]

One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3

and slope m = $\frac{(-3-3)}{0-(-2)}$

$= \frac{-6}{2}= -3$

So the equation of line will be $y= -3x -3$

And the inequality should be $y\geq -3x-3$

Or $3x +y \geq -3$

And the other line passes through (-2,3) and (0,2)

So the y intercept is b=2

and the slope is $m= \frac{2-3}{0-(-2)} = \frac{-1}{2}$

So the equation of line will be $y= \frac{-1}{2} x +2\\and the inequality should be y \leq \frac{-1}{2} x+2$

$2y +x \leq 4$

So answer is $3x +y \geq -3, x+2y\leq 4$

Determine the slope of the line that contains the given points J(-5, -2), K(5, −4)

Irina-Kira [14]

Answer:

$-\frac15$

Step-by-step explanation:

Hello!

We can utilize the slope formula to find the slope.

Slope Formula: $S = \frac{y_2-y_1}{x_2-x_1}$

Remember that a coordinate is written in the form (x,y)

<h3>Find the Slope</h3>

$S = \frac{y_2-y_1}{x_2-x_1}$
$S = \frac{-4-(-2)}{5-(-5)}$
$S = \frac{-2}{10}$
$S = -\frac15$

The slope of the line is $-\frac15$ .

suppose the annual rate of inflation is about 4% this means that the cost of an item increases by about 4%. write and evaluate a

Mashcka [7]

Cost = (3,500) * (1.04)^years
Cost = (3,500) * (1.04)^4
Cost = (3,500) * 1.16985856 
Cost = 4,094.50
