What is the sum of 2x^2-x and -x-2x^2-2

Lorico [155]

<h2>Answer:</h2><h3>-2x-2</h3>

 $solution \\ {2x}^{2} - x + ( - x - {2x}^{2} - 2) \\ = {2x}^{2} - x - x - {2x}^{2} - 2 \\ = {2x}^{2} - {2x}^{2} - x - x - 2 \\ = - 2x - 2$ 

Hope it helps

Good luck on your assignment

А A B D If m_ABD = 64°, and mZCBD = 30°, then m ABC = [?]°

Zina [86]

Answer:

34 degrees

Step-by-step explanation:

If ABD = 64, and CBD is 30, we can use PWP( Part Whole Postulate)

Step 1.CBD + ABC = ABD

Step 2. Substitute

30 + ABC = 64

Step 3. Isolate ABC

34 = ABC

ABC is 34 degrees

The patient recovery time from a particular surgical procedure is normally distributed with a mean of 5.9 days and a standard de

FrozenT [24]

The 70th percentile is the same as the cutoff recovery time $t$ such that every point above this time falls in the longest 30%, i.e.

$\mathbb P(X>t)=0.30$

Transform to the standard normal distribution:

$\mathbb P\left(\dfrac{X-5.9}{2.5}>\dfrac{t-5.9}{2.5}\right)=\mathbb P(Z>t^*)$

where $t^*$ is the z-score corresponding to the cutoff time $t$ , which is approximately $t^*\approx0.5244$ . Solve for $t$ :

$t^*\approx0.5244=\dfrac{t-5.9}{2.5}\implies t\approx7.21\text{ days}$

Answer:

Step-by-step explanation:

1) (-6 , 2) ; (3 , -5)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{-5-2}{3-[-6]}\\\\= \frac{-5-2}{3+6}\\\\= \frac{-7}{9}\\$

m = -7/9 ; (-6 , 2)

y - y₁ = m(x -x₁)

y - 2 = (-7/9)(x - [-6])

$y - 2 = \frac{-7}{9}(x + 6)\\\\y -2 = \frac{-7}{9}x + \frac{-7}{9}*6\\\\y - 2 = \frac{-7}{9}x - \frac{7*2}{3}\\\\ y = \frac{-7}{9}x - \frac{14}{3} + 2\\\\y = \frac{-7}{9}x -\frac{14}{3} + \frac{2*3}{1*3}\\\\y = \frac{-7}{9}x - \frac{14}{3} + \frac{6}{3}\\\\y = \frac{-7}{9}x - \frac{8}{3}$

2) (3 , -4) ; m= 3

$y - y_{1} = m(x - x_{1}$ )

y - [-4] = 3(x - 3)

y + 4 = 3x - 3*3

y + 4 = 3x - 9

y = 3x - 9 - 4

Ans: y = 3x - 13

3) m = 2 ; y-intercept (b) = 3/2

y = mx + b

Ans: y = 2x + (3/2)

4) (-1, 3 ) ; (2 , 0)

Slope = $\frac{0 - 3}{2-[-1]}$

$= \frac{-3}{2+1}\\\\= \frac{-3}{3}\\\\= 1$

m = 1; ( -1 , 3)

y - 3 = 1(x -[-1])

y - 3 = 1(x + 1)

y - 3 = x + 1

y = x + 1 + 3

Ans: y = x + 4

5)(2, 1) ;m = -3

y - 1 = (-3)(x - 2)

y - 1 = -3x + 6

y = -3x + 6 +1

Ans: y = -3x + 7
