5x^2 = 10x 

5x^2-10x=10x-10x 

5x^2-10x=0 

     Use quadratic formula 

\quad x_{1,\:2}=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a} 

\mathrm{For\:}\quad a=5,\:b=-10,\:c=0:\quad x_{1,\:2}=\dfrac{-\left(-10\right)\pm \sqrt{\left(-10\right)^2-4\cdot \:5\cdot \:0}}{2\cdot \:5} 

x=\dfrac{-\left(-10\right)+\sqrt{\left(-10\right)^2-4\cdot \:5\cdot \:0}}{2\cdot \:5}:\quad 2 

x=\dfrac{-\left(-10\right)-\sqrt{\left(-10\right)^2-4\cdot \:5\cdot \:0}}{2\cdot \:5}:\quad 0 

x=2,\:x=0

To begin factoring, set the equation equal to zero - subtract 10x from each side:

5x² = 10x
5x² - 10x = 0

Next, see if you can pull out a GCF, --greatest common factor-- from both terms.  You can pull out 5x:

5x² - 10x = 0
5x(x - 2) = 0

The most you can factor the expression is 5x(x - 2) = 0.

Nostrana [21]

Answer:

car help

Step-by-step explanation:

In order to determine which type of house insurance would be considered as cheapest first it is necessary to determine either monthly or either weekly

So For Car Help, the monthly would be

= $8.60 × 4

= $34.40

And for Car safety, the quoted price is $36.10 per week

So according to the above calculation the car help would be choose as the cheapest

Does anyone know how to do this (#2) PLZZZZ HELPPPPPPPP
timurjin [86]

Answer:

a.- slope= 36

Interpretation : The cable car travels 36 meter per minute

b.- y = 36x + 100

c.- 640 meters

Step-by-step explanation:

a.-

Find slope using the slope formula : \frac{y2-y1}{x2-x1}

Plug in the two given points: \frac{1000-100}{25-0}

Subtract the numbers : \frac{900}{25}

Reduce the fraction : 36

b.-

Using the given y-interspet (100) and the slope create an equation: y = 36x + 100

c.-

Using the equation you created plug in 15 for x to find the

distance: y = 36 (15) + 100

Multiply the numbers : y = 540 + 100

Add the numbers : y = 640

Talia gave her hairdresser a 20 percent tip, which amounted to $7. What was the price of the service before the tip?
mina [271]
I don't know if I did it right but here's my guess. I think you multiply 7 by 20% and that gives you 1.40 as a result. Compared to the other method I used (division), I'm pretty sure I'm right since the other result was 35. Doesn't make sense if the end amount was $7.

Using the normal distribution, the area underneath the shaded region <u>between the two z-scores</u> is given by:

C. 0.6766.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

Hence, for this problem, the area is the <u>p-value of z = 0.75 subtracted by the p-value of z = -1.3</u>.

Looking at the z-table, the p-values are given as follows:

  • z = 0.75: 0.7734.
  • z = -1.3: 0.0968.

Then:

0.7734 - 0.0968 = 0.6766.

Which means that option C is correct.
