What is the slope of the line that passes through the points (-2, -1) and (2, -3)?
Answer:
[tex]m=\frac{-1}{2}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in the 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-3-(-1)}{2-(-2)}[/tex]
[tex]m=\frac{-3+1}{2+2}[/tex]
[tex]m=\frac{-2}{4}[/tex]
[tex]m=\frac{-1}{2}[/tex]
What is the midpoint of a line segment with the endpoints of (-4, -4) and (6, 14)
(10, 18)
(2, 10)
(-1, 4)
(1, 5)
Answer:
The midpoint is ( 1,5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2
( -4+6)/2 = 2/2 =1
To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2
( -4+14)/2 = 10/2 =5
The midpoint is ( 1,5)

At a little-known vacation spot, taxi fares are a bargain. A 12-mile taxi ride takes 18 minutes and costs $7.20. You want to find the cost of a 46-mile taxi ride. What unit price do you need?
Answer:
unit cost in dollars per mile
Step-by-step explanation:
You are given cost, miles, and time for a certain trip.
You are asked the cost for a certain number of miles, so you need a unit cost of dollars per mile.
$7.20/(12 miles) = $0.60/mile
$0.60/mile * 46 miles = $27.60
By first finding the unit cost per mile, you can then find the cost of the 46-mile trip.
Answer:
0.40, mile
Step-by-step explanation:
because you had to multiply to get the total cost and then divide the number by the total cost.

Given function to us is : ⅚ x + 1 .
Here is step by step explanation :
Step 1 : Replace h(x) with y .
The equation becomes ,
⇒ y = ⅚x + 1 .
Step 2 : Interchange the variables .
⇒ x = ⅚y + 1.
Step 3 : Solve for y .
⇒x = ⅚ y + 1.
⇒ x - 1 = ⅚y .
⇒ y = 6/5 ( x - 1 )
⇒ y = 6/5x - 6/5 .

i need helppppp really fast I just need you to check my answer please
Answer:
You are correct, the answer is D, 24 degrees
Step-by-step explanation:
First we know that a straight line is 180 degrees. We know that part of it is 156 degrees so that must mean that one side of the triangle is equal to 24 degrees (Subtract 180-156). That is one side.
What is the inverse of the function f(x)=1/9x+2
Answer:
f ^− 1 ( x ) = 9 x − 18
Step-by-step explanation:
To find the inverse, interchange the variables and solve for y .
Answer:
Add x x and 0 0 . Since g(f(x))=x g ( f ( x ) ) = x , f−1(x)=9x−18 f - 1 ( x ) = 9 x - 18 is the inverse of f(x)=19x+2 f ( x ) = 1 9 x + 2

Un padre está usando una manguera de jardín para llenar una pequeña piscina inflable para su hijo pequeño. La piscina tiene una capacidad de 90 galones. Apaga el agua después de 5 minutos, pero deja la manguera en la piscina durante otros 3 minutos antes de guardarla. En esta situación, la relación entre los galones de agua en la piscina y los 8 minutos desde que el padre comenzó a llenar la piscina puede verse como una función. 1. En esa función, ¿qué variable es independiente? ¿Cuál es dependiente?
Answer:
Water is being collected at the rate of 11.25 gallon per minute.
Step-by-step explanation:
In this function the filling of water in the pool is dependent on the number of minutes. The more time the tap is opened the greater amount of water can be accumulated in the pool .
So time is independent and water is the dependent variable.
The function can be represented by
f(x)= xt where t is the time in minutes
90 gallons= x * 8 minutes
or x= 90/8 = 11.25 gallon per minute.
So water is being collected at the rate of 11.25 gallon per minute.
Spanish
En esta función, el llenado de agua de la piscina depende de la cantidad de minutos. Cuanto más tiempo se abre el grifo, mayor cantidad de agua se puede acumular en la piscina.
Entonces el tiempo es independiente y el agua es la variable dependiente.
La función se puede representar por
F (x) = xt donde t es el tiempo en minutos
90 galones = x * 8 minutos
o x = 90/8 = 11,25 galones por minuto.
Entonces, el agua se recolecta a una velocidad de 11.25 galones por minuto.

what’s 2/3 times 1/8????
Answer:
0.0833333333, or 1/12
Step-by-step explanation:
step 2 Multiply both numerators
= 2 x 1
= 2
step 3 Multiply both denominators
= 3 x 8
= 24
step 4 Use above values of step 2 & 3, and rewrite as below
= 2/24
Thus, 2/24 is equivalent fraction for 2/3 times of 1/8, and its simplified term is 1/12.
Hope this helps!

It costs Ruth $12.50 a week to wash and dry her clothes at the laundromat. If a
washer and dryer cost a total of $940, how many weeks will it take for Ruth's laundry
cost to equal the cost of the washer and dryer?
Answer: 75.2 per week
Step-by-step explanation:
A 76 weeks for Ruth's laundry cost to equal the cost of the washer and dryer.
To find out how many weeks it for Ruth's laundry cost to equal the cost of the washer and dryer, to set up an equation.
Let's assume it takes "x" weeks for Ruth's laundry cost to equal the cost of the washer and dryer.
In one week, Ruth's laundry cost is $12.50. Therefore, in "x" weeks, her total laundry cost would be 12.50 × x.
The cost of the washer and dryer is $940.
Now set up the equation:
12.50 × x = 940
To solve for "x," divide both sides of the equation by 12.50:
x = 940 / 12.50
x = 75.2
Therefore, it will take approximately 75.2 weeks for Ruth's laundry cost to equal the cost of the washer and dryer. Since the number of weeks cannot be fractional, round up the answer to the nearest whole number.

Tip = $28.72 x 15% = $4.308
=> Final cost = $28.72 + $4.308 = $33.208
Answer:
33.03

Michael is saving to buy a car. He has 1/4 what he needs to buy the car. His savings account has a balance of $1000. How much more does he need to save?
Answer:
3000
Step-by-step explanation:
If you take the amount he already has (1000) and multiply by the reciprocal (4) you'll get $4000, the amount that the car costs. From there subtract the amount he already has (1000) and you get the amount he still needs (3000).

10 + 6x = 15 + 9x – 3x
Answer:
No solution
Step-by-step explanation:
Step 1: Write equation
10 + 6x = 15 + 9x - 3x
Step 2: Solve for x
Combine like terms: 10 + 6x = 15 + 6xSubtract 6x on both sides: 10 ≠ 15Here, we see that x would equal no solutions. You can also think of it as parallel lines; they have the same slope but different y-intercepts, so they will never intersect.
I'll give you 100 points if you answer this correctly!!
Make a table of ordered pairs for the equation.
y=−1/3x+4
Then plot two points to graph the equation.
Let's pose x as 0, 1, 2, and 3, substituting for y to receive the "ordered pairs"
y = - 1/3(0) + 4 = 0 + 4 = 4
y = - 1/3(1) + 4 = - 1/3 + 4 = - 1/7
y = - 1/3(2) + 4 = - 2/3 + 4 = 10/3
y = - 1/3(3) + 4 = - 1 + 4 = 3
Table of ordered pairs:
x | y
