Answer:

$x_1=1.23\\x_2=-0.40$

Step-by-step explanation:

Given a quadratic equation in the form $ax^2+bx+c=0$ , you can use the Quadratic formula to solve it. This is:

$x=\frac{-b\±\sqrt{b^2-4ac}}{2a}$

Then, you need to subtract $5x$ from both sides of the equation given:

$5x-5x=6x^2-3-5x\\0=6x^2-5x-3$

You can identify that:

$a=6\\b=-5\\c=-3$

Then, substituting values into the Quadratic formula, you get:

$x=\frac{-(-5)\±\sqrt{(-5)^2-4(6)(-3)}}{2(6)}$

$x_1=1.23\\x_2=-0.40$

$5 \frac{3}{5} + 2 \frac{1}{10} \\ = \frac{28}{5} + \frac{21}{10} \\ = \frac{56}{10} + \frac{21}{10} \\ = \frac{77}{10} \\ = 7 \frac{7}{10}$

Hope it helps and is useful :)

In general. A clock that is 3 seconds slow but keeps consistent time will be more accurate than a clock that loses 1 second ever

Pani-rosa [81]

True.

If the clock loses 1 second every hour that passes then after 4 hours it will be 4 seconds off, 5 hours will be 5 seconds off, etc. It would continue and turn into minutes and hours off.

10a. The y-intercept of the estimated line of best fit is at (0,b). Enter the approximate value of b. Round your estimate to the

vredina [299]

Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given as:

y = mx + b; where m is the slope of the line and b is the y intercept (that is value of y at x = 0).

a) From the graph, we can see that the straight line touches the y axis at $100 in which the temperature is 0 degrees. Therefore the y intercept is:

(0, 100)

b) The slope of the line can be gotten by taking two points that the line passes through. Using the points (0, 100) and (12, 500):

$slope(m)=\frac{y_2-y_1}{x_2-x_1} =\frac{500-100}{12-0} =33.3$

What is the solution for: 10n^2+n^2+16

ivanzaharov [21]

The solution is n= + 4i/√11

Step-by-step explanation:

step 1: 10n^2+n^2+16=0

step 2: 11n^2+16=0

step 3: 11n^2= -16

step 4: n^2= -16/11

step 5: taking square root on both sides,

n= √(-16)/√11 (square root of a negative number is a complex term 'i')

n= + 4i/√11
