Answer:

let's call 8x-6  A and

2xsq - 3x + 5  B

so in the left column the first equations simplifies out to a

the second equation in the left column simplifies out to a

the third equation in the leftcolumn simplifies out to b

in the right column the first equation simplifies out to b

in the second equation right column simplifies out to b

hope this helps

Answer:

(x^2 - 6x + 7) - (x^2 - 14x + 13) → <u><em>Category 1</em></u>

8x - 6 (The x^2 cancel out)

2(x^2 - 4x) + 5(x + 1) → <u><em>Category 2</em></u>

(2x^2 - 8x) + (5x + 5)

2x^2 - 3x + 5

x(2x + 1) - (4x - 5) → <u><em>Category 2</em></u>

(2x^2 + x) - (4x - 5)

2x^2 -3x + 5

x(3x - 4) - 3(x^2 + 2) + 12x → <u><em>Category 1</em></u>

(3x^2 - 4x) - (3x^2 + 6) + 12x

8x - 6

x(x + 1) + x(x + 1) - 4(x^2 - 1.5x) + 2(x^2 - 3) → <u><em>Category 1</em></u>

<em>(x^2 + x) + (x^2 + x) </em><u><em>-</em></u><u> (4x^2 - 6x) + (2x^2 - 6)</u>

<em>(2x^2 + 2x) - </em><u>(2x^2 - 6x - 6)</u>

8x - 6

Consider the given vector equation. r(t) = 2eti + 3e−tj (a) find r'(t). r'(t) = &lt;2et,−3e−t&gt; (b) sketch the plane curve tog
Fofino [41]
(a) Differentiate each of the components to get r'(t). The rule is
.. d/dt (a*e^(bt)) = a*b*e^(bt)
The answer you have shown is the correct one.

(b) See the figure. The red curve is the position r(t) for 0 ≤ t ≤ 2. The dashed orange line is the tangent line, whose equation is
.. L(t) = r(0) +r'(0)*t = (2 +2t)i +(3 -3t)j

How are geometric sequences similar to arithmetic sequences? How are they different?
ollegr [7]
The differences between arithmetic and geometric sequences is that arithmetic sequences follow terms by adding, while geometric sequences follow terms by multiplying. The similarities between arithmetic and geometric sequences is that they both follow a certain term pattern that can't be broken. There you go

The difference between the observed value of the dependent variable and the value predicted using the estimated regression equat
Elenna [48]

Answer:

For this case we define the dependent variable as Y and the independent variable X. We assume that we have n observations and that means the following pairs:

(x_1, y_1) ,....,(x_n,y_n)

For this case we assume that we want to find a linear regression model given by:

\hat y = \hat m x +\hat b

Where:

\hat m represent the estimated slope for the model

\hat b represent the estimated intercept for the model

And for any estimation of the dependent variable \hat y_i , i=1,...,n is given by this model.

The difference between the observed value of the dependnet variable and the value predicted using the estimated regression equation is known as residual, and the residual is given by this formula:

e_i = y_i -\hat y_i , i=1,...,n

So the best option for this case is:

d. residual

Find the slope of the line whose equation is 7x - 2y = 4.<br> -2<br> 7/2<br> 4/7
sesenic [268]
Answer: 7/2

To find the slope, we must put the equation in y = mx + b form, and m represents ur slope.

7x - 2y = 4....subtract 7x from both sides
-2y = -7x + 4 ...now divide both sides by -2
y = (-7/-2)x + (4/-2)
y = 7/2x - 2....now we have it in y = mx + b form, and since m is ur slope, ur slope in this equation is 7/2.
