Write three rational expressions that simplify to (x+1)/(x-1)

Branliest solve the equation 8.7=3.5m-2.5(5.4-6m)

ira [324]

Simplifying
8.7 = 3.5m + -2.5(5.4 + -6m)
8.7 = 3.5m + (5.4 * -2.5 + -6m * -2.5)
8.7 = 3.5m + (-13.5 + 15m)

Reorder the terms:
8.7 = -13.5 + 3.5m + 15m

Combine like terms: 3.5m + 15m = 18.5m
8.7 = -13.5 + 18.5m

Solving
8.7 = -13.5 + 18.5m

Solving for variable 'm'.

Move all terms containing m to the left, all other terms to the right.

Add '-18.5m' to each side of the equation.
8.7 + -18.5m = -13.5 + 18.5m + -18.5m

Combine like terms: 18.5m + -18.5m = 0.0
8.7 + -18.5m = -13.5 + 0.0
8.7 + -18.5m = -13.5

Add '-8.7' to each side of the equation.
8.7 + -8.7 + -18.5m = -13.5 + -8.7

Combine like terms: 8.7 + -8.7 = 0.0
0.0 + -18.5m = -13.5 + -8.7
-18.5m = -13.5 + -8.7

Combine like terms: -13.5 + -8.7 = -22.2
-18.5m = -22.2

Divide each side by '-18.5'.
m = 1.2

Simplifying
m = 1.2

Label the parts of the triangle. leg leg altitude hypotenuse right angle

andriy [413]

Answer: See Below

Step-by-step explanation:

One part we can label right off the bat is right angle. It is denoted with the red box. It forms a 90° angle, which is a right angle. At the very top pointing to the right angle, is right angle.

Altitude is another way of saying height. It is how tall the triangle is. The line that shows how tall the triangle is, is the line going down the triangle in the middle. That line is altitude.

Hypotenuse is the longest side of the triangle. It is also located directly across the right angle. Looking at the right angle, the bottom line is the hypotenuse.

Since we have 2 sides left, they are obviously the legs of the triangle.

Which function is decreasing?

madam [21]

Answer:

A

outdoor temperature as a function of time

Step-by-step explanation:

If you put the temperture as a function of time, every passing hour or minute the tempurture decreases resulting in a decrease in your function.

This can also be shown in a graph were the tempuerture is the x and the time is the y. Each hour that passes the temputure goes down until night falls and the temputure reaches a constant rate of tempurture

Holli's house is located at (−1, 4). She can walk in a straight line to get to Jedd's house. A fast food restaurant is located a

GrogVix [38]

Answer:

The coordinates of Jedd's house is (-5, 0)

Step-by-step explanation:

Given;

Location of Holli's House = (−1, 4)

Location of fast food restaurant = (−3, 2)

To Find:

The coordinate of Jedd's house.

Solution:

If the distance between the two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$ is divided by the point (x,y) in the ratio of m : n then

$x=\frac{x_{1}n+x_{2}m}{m + n}$

$y=\frac{y_{1}n+y_{2}m}{m + n}$

Hollis house is located at (-1 , 4)

So, $(x_{1},y_{1}) = (-1 , 4)$

She walks in a straight line to get to Jedds house

The restaurant is located at (-3 , 2) and partitions the way from

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

The ratio of Hollis house to Jedds house is 1 : 1

(m : n) = 1 : 2

Lets consider that Jedds house is located at $(x_{2},y_{2})$

Then $x_2$ will be

$-3=\frac{-1(1)+x_{2}(1)}{1+1}$

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

$-3 \times 2=-1 +x_{2}$

$-6 = -1 +x_{2}$

$-5 = x_{2}$

Now $y_{2}$ will be

$2=\frac{4(1)+y_{2}(1)}{1+1}$

$2=\frac{4+y_{2}}{2}$

$2 \times 2=4+y_{2}$

$4 = 4+y_{2}$

$4 - 4 = y_{2}$

$y_{2} = 0$

∴ The coordinates of Jedd's house is (-5, 0)

Annalise withdraws $22.50 each day from her account for a week. How can you represent the change in her account after 2 weeks?

nadya68 [22]

Answer: She would have $315

Because there are 7 days in a week so you multiply 22.50 by 7 and you get 157.5, Then because she does it for two weeks you multiply 157.5 by 2 and you get 315

Hope this helps
