<h3>The two solutions are: x = 0 and x = 1/2</h3>

====================================================

Work Shown:

10x^2 - 5x = 0

5x(2x - 1) = 0 .... factor out the GCF

5x = 0 or 2x-1 = 0 .... zero product property

x = 0/5 or 2x = 1

x = 0 or x = 1/2

Note: 1/2 = 0.5

We could use the quadratic formula here, or we could complete the square, but that's overkill in my opinion.

How to solve 2/3(6x-9)=-34

castortr0y [4]

$\frac{2}{3} (6x-9)=-34 \\ \\ \frac{2(6x - 9)}{3} =-34 \\ \\ \frac{2 \times 3(2x-3)}{3} =-34 \\ \\ \frac{6(2x - 3)}{3} = -34 \\ \\ 2(2x - 3) = -34 \\ \\ 2x - 3 - \frac{34}{2} \\ \\ 2x - 3 = -17 \\ \\ 2x -17 + 3 \\ \\ 2x = -14 \\ \\ x = - \frac{14}{2} \\ \\ x = -7 \\ \\ Answer: \fbox {x = -7}$

Which of the following best describes interval C on the graph shown?

Slav-nsk [51]

Note: <em>The missing graph is attached below. </em>

Answer:

'linear decreasing' best describes interval C on the graph shown.

Step-by-step explanation:

Note: <em>The missing graph is attached below. </em>

From the attached graph, it is easy to figure out that the interval C on the graph shown is showing a straight line. So the graph of the function would be linear.

Also on the interval C, the value of y is decreasing as the value of x increase. So, the slope of the straight line would be negative.

So the interval C indicates that the function is decreasing there.

Therefore, 'linear decreasing' best describes interval C on the graph shown.

Need help on this please this one is hard for me

Answer:

y = -7x

Step-by-step explanation:

The line goes through the origin, so the y-intercept is b=0.

The line goes through the point (1, -7), so has a "rise" of -7 for a "run" of 1. The slope is ...

m = rise/run = -7/1 = -7

Then the slope-intercept form equation is ...

y = mx + b

y = -7x

What should be the paper weight

nata0808 [166]

Answer:

6.25 cm

Step-by-step explanation:

$\rho=\dfrac{m}{V} \\\\V_{\text{pyramid}}= A_{\text{base}}\cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{V} \\\\V=120 \cdot h \cdot \dfrac{1}{3} \\\\1.6=\dfrac{400}{40h} \\\\1.6=\dfrac{10}{h} \\\\1.6h=10 \\\\h=\dfrac{10}{1.6}=6.25\text{ cm}$

Hope this helps!
