To solve for the variable b , we have to make it alone. The first thing we do is add 6.5 to both sides of the equation:

13.7b-6.5+6.5=-2.3b+8.3+6.5\\13.7b=-2.3b+14.8

Now add 2.3 to both sides:

13.7b+2.3b=-2.3b+14.8+2.3b\\16b=14.8

Finally, divide both sides by 16 to get the final answer:

\frac{16b}{16} =\frac{14.8}{16}

Therefore,

b=0.3

Hope this helps!

Suppose the roots of the equation 2x^2−5x−6=0 are α and β.Find the quadratic equation with roots 1/α and 1/β.​
pochemuha

Answer:

6x² + 5x - 2 = 0

Step-by-step explanation:

Given

2x² - 5x - 6 = 0 ← in standard form

with a = 2, b = - 5, c = - 6, then

sum of roots α + β = - \frac{b}{a} = \frac{5}{2}

product of roots = \frac{c}{a} = - 3, then

sum of new roots = \frac{1}{\alpha } + \frac{1}{\beta }

= \frac{\beta+\alpha  }{\alpha \beta }

= \frac{\frac{5}{2} }{-3} = - \frac{5}{6}

product of new roots = \frac{1}{\alpha } × \frac{1}{\beta }

= \frac{1}{\alpha\beta  } = - \frac{1}{3}

Hence the required equation is

x² + \frac{5}{6} x - \frac{1}{3} = 0 or

6x² + 5x - 2 = 0 ( multiplying through by 6 )

The air Temperature is -12C at sunrise and rises 4 degrees c every hour for several hours the air temperature after x hours is r
Stolb23 [73]

Let f(x) = y.

y = 4x - 12

Let x = 0

y = 4(0) - 12

y = - 12

This leads to the point (0, -12).

Let y = 0.

0 = 4x - 12

1 2 = 4x

12/4 = x

3 = x

This leads to the point (3, 0).

We now graph both points and then connect each point with a straight line.
