Answer:

$a_n=-5-2(n-1)$

Step-by-step explanation:

Since this sequence starts with -5 and decreases by 2 with each term, its rule would be:

$a_n=-5-2(n-1)$

Hope this helps!

Which of these strategies would eliminate a variable in the system of equations? 8x+8y=2 8x+5y=1 Add the equations. (Choice B

harkovskaia [24]

Answer:

B. Subtract the bottom equation from the top equation.

Step-by-step explanation:

When looking at the two equations:

8x + 8y = 2

8x + 5y = 1

We can easily get rid of the x variable by subtracting the two equations from each other since the terms are equivalent. This would allow us to solve for the y value, which we could plug into the an equation to solve for the x value.

A test of abstract reasoning is given to a random sample of students before and after they completed a formal logic course. The

Natasha_Volkova [10]

Answer:

The right answer is " $0.2$ ".

Step-by-step explanation:

The given values are:

$\bar{x_0} = 3.7$

$s_o=4.95$

$t_{\frac{0.05}{2} }=2.2621$

As we know,

95% confidence for $\mu_0$ will be:

= $\bar{x_0} \pm t_{\frac{0.05}{2} },n-1\times \frac{s_o}{\sqrt{n} }$

The lower bound will be:

= $3.7-2.2621\times \frac{4.95}{\sqrt{10} }$

= $0.16\simeq 0.2$

The upper bound will be:

= $3.7+2.2621\times \frac{4.95}{\sqrt{10} }$

= $7.23\simeq7.2$

Thus the right answer is " $0.2$ "

What is the answer to this system of equations? 2x - 3y= 21 and -6x + 2y = 7.

allsm [11]

answer:

x = - 9/2

y = -10

Step-by-step explanation:

make both equations look like y =

2x-3y=21 -> -3y= -2x+21 -> y = (-2x+21)/-3 -> y = 2/3x - 7

-6x + 2y = 7 -> 2y = 6x + 7 -> y = 3x + 7/2

now make the equations equal to each other (since they both equal y)

get x

2/3x - 7 = 3x + 7/2

-7 -7/2 = 3x - 2/3x

-14/2 -7/2 = 9/3x - 2/3x

-21/2 = 7/3x

(3/7) -21/2 = x

x = (3/7) -21/2

x = - 63/14

x = - 9/2

put it back in an equation to get y

y = 3x + 7/2

y = 3(-9/2) + 7/2

y = -27/2 + 7/2

y = -20/2

y = - 10

Polygon ABCD was dilated by a scale factor of 3/2 to form polygon A'B'C'D'. The scale factor used was 3/2. The length AB is 2 and the length A'B' is 3.

<h3>What is a transformation?</h3>

Transformation is the movement of a point from its initial location to a new location. Types of transformation are translation, rotation, reflection and dilation.

Dilation is the increase or decrease in the size of a figure.
