The coordinates of the midpoint of AB is (4.5, -1.5)

We can find this by taking the average of each coordinate. The average of the x's (2 and 7) is 4.5, while the average of the y's (-4 and 1) is -1.5.

The coordinates of the midpoint of CD is (-5.5, 1)

We can find this by taking the average of the coordinates as we did in the first one. The average of the x's (-3 and -8) is -5.5, while the average of the y's (-2 and 4) is 1.

What’s the fifth term of a sequence whose first term is 5 and whose common ratio is 3?
SSSSS [86.1K]

Answer:

405.

Step-by-step explanation:

This is a geometric sequence where the nth term = a1 r^(n -1).

Here a1 = 5 and r = 3 so

the fifth term a5 = 5(3)^(5-1)

= 5 * 81

= 405.

What is the equation of the line that passes through the point (5,0) and has a slope<br> of -1
erica [24]

Answer:

y = -x + 5

Step-by-step explanation:

X, Y, and B is given using fomula y = m(x) + b

Subsitute those variables.

0 = -(5) + b

Solve for m.

0 = -5 + b

+5  +5

b = 5.

Then plug in the b and take out the x and y.

y = -x + 5

Evaluate the following expression (-3)^-2
OleMash [197]
<h3>Answer: the fraction 1/9</h3>

It is approximately equal to 0.1111

=================================

To get this answer, we use the rule

x^{-k} = \frac{1}{x^k}

The negative exponent tells us to apply the reciprocal to get the exponent to be positive.

So,

(-3)^{-2} = \frac{1}{(-3)^2}\\\\(-3)^{-2} = \frac{1}{9}

Squaring -3 means you square the negative as well

(-3)^2 = (-3)*(-3) = 9
