Step-by-step explanation:
The equations with solution x = 1 and y = (-1) will intersect each other at (1,-1) .
Equation 1 :-
Say slope is 1 .→ y - (-1) = 1 ( x -1)
→ y +1 = x -1
→ x - y -2 = 0
Equation 2 :
Slope = -1→ y - (-1) = -1( x -1)
→ y +1 = -x +1
→ x + y = 0

Jack and Jill collect coins. Jack has 56 coins, and Jill has 80 coins. Both recently joined a coin-collecting club. Jack's club will send him 12 new coins per month, and Jill's club will send her 8 new coins per month. After how many months will Jack and Jill have the same number of coins?
Answer:
So, after 6 months, they both have the same number of coins.
Step-by-step explanation:
Jack has 56 coins
Jill has 80 coins
Jack collect 12 coins per month
Jill collect 8 coins per month
Let after m months, they both have the same coin.
56 + 12 m = 80 + 8 m
12 m - 8 m = 80 - 56
4 m = 24
m = 6
So, after 6 months, they both have the same number of coins.
A una reunión asistieron tres amigos: Manuel, Hugo y Coco; y tres damas: Pamela, Nancy y Susan. Terminada la actividad, cada uno de los muchachos salió acompañado por una dama. Hugo salió con la amiga de Nancy. Pamela, que no simpatiza con Nancy, salió antes que Manuel.
Answer:
Hugo salió con Susan, Coco salió con Pamela y Manuel salió con Nancy.
Step-by-step explanation:
Dado que a una reunión asistieron tres amigos: Manuel, Hugo y Coco; y tres damas: Pamela, Nancy y Susan, y terminada la actividad, cada uno de los muchachos salió acompañado por una dama, y Hugo salió con la amiga de Nancy, mientras que Pamela, que no simpatiza con Nancy, salió antes que Manuel, para determinar con quién salió cada persona debemos realizar el siguiente razonamiento lógico:
Hugo = Amiga de Nancy (no es Pamela) = Susan
Pamela = Sale antes que Manuel (no sale con Hugo) = Coco
Nancy = Manuel
Por lo tanto, Hugo salió con Susan, Coco salió con Pamela y Manuel salió con Nancy.

The weight of water is 0.036 pounds times the volume of water in cubic inches. How many pounds of water would fit into a fish tank shaped like a rectangular prism that is 14 inches deep, 25 inches wide, and 38 inches long? Round your answer to the nearest tenth when you enter it.
Answer:
Step-by-step explanation:
The weight of water is 0.036 pounds times the volume of water in cubic inches.
Volume of the tank = Length × Width × Height
= 14 × 25 × 38
= 13300 cubic inches

2- Guillermo envasa 355 ml de agua
fresca en cada botella. ¿Cuantas botellas
se necesitan para envasar 29,730,895 ml?
Answer:
83,749 bottles
Step-by-step explanation:
Each bottle contain = 355ml
Total water need to pack = 29,730,895 ml
So, we can calculate the number of bottles by using following formula,
Number of bottles required = Total water ÷ Each bottle contain
by putting the value, we get
Number of bottles required = 29,730,895 ÷ 355
= 83,749
Hence, total number of bottles required is 83,749.

Zeek then want to ride his bike to the old spaghetti factory. He wondering if he should bike 1 mile north, then 0.5 miles directly east, or if he should just go directly there to bike the shortest distance.
Answer:
He should travel directly
Step-by-step explanation:
Given
[tex]x = 0.5[/tex] --- East
[tex]y =1[/tex] --- North
If he goes through east north direction, the distance (d) traveled is:
[tex]d = x + y[/tex]
[tex]d = 0.5 + 1[/tex]
[tex]d = 1.5 mile[/tex]
If he travels directly, the distance (d) is:
[tex]d = \sqrt{x^2 + y^2}[/tex] ---- Pythagoras theorem
[tex]d = \sqrt{0.5^2 + 1^2}[/tex]
[tex]d = \sqrt{0.25 + 1}[/tex]
[tex]d = \sqrt{1.25}[/tex]
[tex]d = 1.12mile[/tex]
By comparison, he will travel the shortest distance if he travels directly because [tex]1.12 < 1.5[/tex]
Hence, he should travel directly

Answer:
n ≥ -5/14
Step-by-step explanation:
64n - 6 ≥ 36n -16
subtract 36n from each side
64n -36n - 6 ≥ 36n-36n -16
28n - 6 ≥ -16
add 6 to each side
28n -6+6 ≥ -16+6
28n ≥ -10
Divide each side by 28
28n/28 ≥ -10/28
n ≥ -5/14
Answer:
n ≥ -5/14
Step-by-step explanation:
64n - 6 ≥ 36n -16
subtract 36n from each side
64n -36n - 6 ≥ 36n-36n -16
28n - 6 ≥ -16
add 6 to each side
28n -6+6 ≥ -16+6
28n ≥ -10
Divide each side by 28
28n/28 ≥ -10/28
n ≥ -5/14

If the board length of an average log is 8.25 and the price per board foot is 7.95. What is the value of the timber if there are 100 logs?
Answer:
6558.75
Step-by-step explanation:
total value of 100 logs = total value of an average log x 100 total value of an average log = length of an average log x price per board foot
8.25 x 7.95 = 65.5875
65.5875 x 100 = 6558.75

Step-by-step explanation:
Given
I will answer this question with the attached plot
Required
The interquartile range (IQR)
This is calculated using:
[tex]IQR = Q_3 - Q_1[/tex]
On the second attachment, I identified Q1 and Q3 on the plot.
So, we have:
[tex]Q_3 = 40[/tex]
[tex]Q_1 = 25[/tex]
[tex]IQR = Q_3 - Q_1[/tex]
[tex]IQR = 40 - 25[/tex]
[tex]IQR = 15[/tex]

x = 50
Step-by-step explanation:
the two angles at the bottom would he the same. Since the interior angles of a triangle must add up to 180 the you just subtract that from 180. 180-(65+65)=50
Answer:
x = 50
Step-by-step explanation:
Since the 2 sides are equal to each other, so are the angles. This is an isoceles triangle, by the way. All triangle interior angles add up to 180.
So, the equation is:
x + 65 + 65 = 180
x + 130 = 180
x = 180 - 130
x = 50
In August, Cory begins school shopping for his triplet daughters. One day, he bought 3 packages of socks for $8 each and 3 pairs of shoes for d dollars each. Which pair of expressions represent the total amount Cory spent? * A. 3d + 8 and (d + 8)(d + 8)(d + 8) B. 3(d + 8) and (d + 8)(d + 8)(d + 8) C. 3d + 8 and (d + 8) + (d + 8) + (d + 8) O D. 31d + 8) and (d + 8) + (d + 8) + (d + 8) What is the value of the expression? (14 72 - 10.25); 2* 1 point
Answer:
D. 3(d + 8) and (d + 8) + (d + 8) + (d + 8)
II. 2.235
Step-by-step explanation:
Given the following data;
3 packages at $8 each = 3 * 8 = $24
3 pair of shoes at $d each = $3d
I. To find the total amount of money Cory spent;
Total = 3d + 24
Factorizing, we have;
Total = 3(d + 8)
II. To find the value of the expression;
Your expression isn't explicitly written but I'll assume it's this;
(14.72 - 10.25)/2 =
4.47/2 = 2.235
