Answer:
The submarine is at -1260 ft.
It descends 5 ft/min for 12 min.
12 min * 5 ft/min = 60 ft.
It descended 60 ft, so you must subtract 60 ft from -1260 ft.
-1260 ft + (-5)(12) ft = -1260 ft - 60 ft = -1320 ft
The error in the last line in the problem is that (-5)(12) = -60, not 60.
The correct line is:
-1260 + (-5)(12) = -1260 - 60 = -1320
Step-by-step explanation:
which is the equation of a line that has a slope of 1/2 and passes through Point (2,-3 )?
Answer:
y = 1/2x - 4
Step-by-step explanation:
y = mx + b
-3 = 1/2(2) + b
-3 = 1 + b
b = -4

what is the area of this parallelogram?
30 inches squared or 30 in^2
All you have to do to find area of a parallelogram is length times width
So 5 times 6 is 30
Don’t forget the unit, which in this case is inches, and anytime you have area, you have to have a squared, or an exponent 2

Two hikers walk on a trail in the direction of increasing mile marker numbers. Mandy starts at mile marker 1 and hikes at a rate of 2.5 miles per hour. At the same time, Rita starts at mile marker 2 and hikes at a rate of 3 miles per hour. The equation 2.5h+1=3h+2 represents the number of hours h it will take Mandy to catch up with Rita.
Let as consider, we need to find the number of hours h it will take Mandy to catch up with Rita.
Given:
The number of hours h it will take Mandy to catch up with Rita is represented by the equation
[tex]2.5h+1=3h+2[/tex]
To find:
The value of h.
Solution:
We have,
[tex]2.5h+1=3h+2[/tex]
Isolate the variable terms on one side.
[tex]2.5h-3h=-1+2[/tex]
[tex]-0.5h=1[/tex]
Divide both sides by -0.5.
[tex]h=\dfrac{1}{-0.5}[/tex]
[tex]h=-2[/tex]
We know that, time cannot be negative. So, [tex]h\neq -2[/tex].
The equation [tex]2.5h+1=3h+2[/tex] is not true for any positive value of h.
Therefore, Mandy will never catch up with Rita.

It’s 13 - 17

lesson 2.6 Properties & algebraic proofs
13. You are correct. You multiply the outer 5 with each term inside, and add.
-----------
14. The number 0 goes in the first blank and 8 goes in the second blank. So we have 8+0 = 8. The identity property of addition says that adding 0 to any number leads to the same result. In terms of algebra, x+0 = x.
-----------
15. The fraction 1/8 goes in the first blank and 1 goes in the second blank. We have the equation 8(1/8) = 1. Multiplying any nonnegative number x with its reciprocal 1/x leads to 1.
----------
16. The number 1 goes in the first blank and -4 goes in the next blank. This property is similar to the property mentioned in problem 14. This time we're working with the multiplicative version. We have the equation -4*(1) = -4
----------
17. The letter a goes in the first blank and x+3 goes in the second blank. So the last equation is a = x+3. The transitive property is the idea of us chaining equations together. It's like saying "if A goes to B, and B goes to C, then A goes to C". Think of it like taking a shortcut bypassing B entirely.
Write a linear function f with f(0)=3 and f(−6)=3
Answer:
y = 3
Step-by-step explanation:
Slope = 0/-6 = 0
y-int. = 3
The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].
Given two distinct points on cartesian plane, we can determine the linear function associated to those points as follows:
[tex]y = m\cdot x + b[/tex] (1)
[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] (2)
[tex]b = y_{1}-m\cdot x_{1}[/tex] (3)
If we know that [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex], then we have the linear function below:
[tex]m = \frac{3-3}{0-(-6)}[/tex]
[tex]m = 0[/tex]
[tex]b = 3 - 0\cdot (0)[/tex]
[tex]b = 3[/tex]
The linear function [tex]f[/tex] with [tex]f(0) = 3[/tex] and [tex]f(-6) = 3[/tex] is [tex]y = 3[/tex].
We kindly invite to check this question on linear functions: https://brainly.com/question/19137465
Town M is 282 feet below sea level. Town R is 679 feet above sea level. How much higher, in feet, is Town R than Town M?
Answer:
397 feet
Step-by-step explanation:
All you have to do is subtract the feet of Town R from Town M. The equation would look like this.
679 - 282 =397
So Town R is 397 feet higher than Town M.

Taylor bought a necklace for each of her three sisters. She paid $7.50 for each necklace. Supposed she had $9 left. How much money did she have initially to spend on each sister?
Answer:
7.50 x 3= 22.50
22.50+9= 31.50
Step-by-step explanation:
If each necklace was $7.50 and she got one for each of her 3 sisters then we need to multiply $7.50 by 3. Finally, she has $9 left over. So if we add the total she spent on the necklaces and the 9 she has left over then we will get the total she started with.

you should start with one subject and finish them up. then move on to the next subject. dont switch subjects and focus. youll get them all sooner if you pay attention. dont cheat!
Answer:
ok, so i feel you. i don't have 150 overdue but i do have 13 lol. so today is wednesday, so you have 6 days. 150÷6=25. so try to do 25 assignments a day. i know it feels sooooo stressful, but i mean you have to make up for all those days you didn't do work. make a list of everything you have to do (on paper or in google docs/notes/word). don't do work in your bed; it makes you feel lazy. do it at a table or desk. clean your work area! have a piece of paper and a pencil so you can work out problems. fill up a glass of water right next to you. play some chill music; NOT your favorite songs! they will distract you! ask your alexa/google home/apple homepod to play some study music, or play it from your phone or whatever. just some background music to help you focus. if you play music from your phone, make sure to keep it on silent and do not disturb so you don't get distracted by notifications. work alone, not in a room with other people. just power through your work. take it one at a time; don't overwork yourself. take breaks if you need to, but don't get too distracted. after you complete your 150 assignments, try to work ahead so this never happens again.

in and her brother each created a scale drawing of the backyard, but at different scales. Lin used a scale of 1 inch to 1 foot. Her brother used a scale of 1 inch to 1 yard. Express the scales for the drawings without units.
Whose drawing is larger?
Answer:
Lin's drawing is larger.
Step-by-step explanation:
Say that their backyard is 1 yard, her brother's scale drawing would only be 1 inch, but Lin's scale drawing would be 3 inches. From this you can take away that the smaller the scale the bigger the scale drawing, (does that sentence make any sense?)

What is the range of this quadratic function?
Answer:
(negative infinity, 4]
Step-by-step explanation:
Reminder: the range is all the possible y values the function can get by plugging in x values.
Since this is a downward opening parabola, it won't have a lower boundary, which means that the answer must be (negative infinity, 4]
We can further check that's correct by seeing that the parabola has its vertex at 4, which is written in the answer.
That means the correct answer must be (negative infinity, 4]

8x = 6 × 8
8x = 48
The perimeter of a rectangle is 64 inches. Find the value of x if the width is 22 inches and tenth is 2x inches.
Answer:
5
Step-by-step explanation:
Did you mean length instead of tenth? If so, 22*2=44, 64-44=20, 20/2=10. The length of the rectangle is 10 so to find the value of x, divide 10 by 2 so, 10/2=5, and x is equal to 5. : )
