to lose 1 lb of body fat you need to burn 3.500 calories. If you burn 450 more calories than you take in each day, how long will it take to lose 1 lb? What about 10 lb?
Step-by-step explanation:
1 pound is equivalent to 3500 calories.
if you burn 450 more calories per day, it will take as many days as the times 450 fits into 3500 :
3500 / 450 = 7.77777777... days
for 10 pounds we need to burn 10×3500 = 35000 calories.
35000 / 450 = 77.77777777... days (10 times more logically than for 1 pound).

Answer:
[tex]f\left(x\right)=\begin{cases}2x\:+\:10&-6\:\le x\: < \:-3\\ -x\:+\:1&-3\: < \:x\: < \:2\end{cases}[/tex]
Step-by-step explanation:
Looking at the graph we can see that it is a linear graph of the form
y = mx + b where m is the slope and b is the y intercept.
In one region the slope is positive and the other region it is negative
Interval 1 is -6 ≤ x < -3
How do I know that one uses a ≤ and the other uses a <?
A filled circle means that the point is included in the domain(range of x values) and therefore (≤, ≥) and an unfilled circle means it is not(<, >)
Find the slope of line in this interval
Take two points, say (-5, 0) and (-3, 4)
Slope = rise/run = (4 - 0)/(-3 - (-5) = 4/2 = 2
So slope of line is 2 and its equation in slope-intercept form is
y = 2x + b
Choose any point, plug in values, solve for b
Point (5, 0) is chosen
0 = 2(-5) + b
0 = -1 + b
or
b = 10
So equation of line in the interval (-6 ≤ x < -3) is
y = f(x) = 2x + 10
Interval 2: -3 < x < 2
We see this line intersects the y axis at y = 1
So b = 1
Equation is y = mx + 1
Choose point x = 0, y = 1 to find slope m
At x = 0, y = m(1) + 1 = m + 1
So m + 1 = 0
m = -1
So equation of this line is
y = f(x) = -1x + 1 in the interval -3 < x < 2
Putting all these together we get the piecewise function as:
[tex]f\left(x\right)=\begin{cases}2x\:+\:10&-6\:\le x\: < \:-3\\ -x\:+\:1&-3\: < \:x\: < \:2\end{cases}[/tex]

_____yards
If 13 cents per yard is the price, and there was $8.63 left on the card, the yards of ribbon Leila bought is 49 yards of ribbon.
How to solve for the amountTo determine the number of yards of ribbon Leila bought, we need to calculate the difference between the initial balance on the prepaid debit card and the remaining balance after the purchase.
Initial balance: $15.00
Remaining balance: $8.63
The difference between these two amounts represents the amount spent on the ribbon:
$15.00 - $8.63 = $6.37
Now, we can calculate the number of yards of ribbon by dividing the amount spent by the price per yard:
$6.37 / $0.13 = 49

A figure is transformed by T(x, y) = (x+3, y-1) and then transformed by S(x-3, y + 1). How does the preimage relate to the final image? please show work sorry
Answer: The preimage and final image are the same point
This applies to every point in the xy plane.
======================================================
Explanation:
Let's say we started with the example point of (5,7)
Put the coordinates of the point into the T(x,y) transformation
We'll replace every x with 5 and every y with 7
So,
T(x, y) = (x+3, y-1)
T(5, 7) = (5+3, 7-1)
T(5,7) = (8, 6)
What does this mean? It means that the original preimage point (5,7) moves to (8,6). This is a shift of 3 units right and 1 unit down.
------------------
Now we'll plug the coordinates of that result, the (8,6), into the transformation of S(x, y) = (x-3, y + 1)
Plug in x = 8 and y = 6 to get...
S(x, y) = (x-3, y + 1)
S(8, 6) = (8-3, 6 + 1)
S(8, 6) = (5, 7)
We have gone from (8,6) to (5,7). We're back where we started.
The second transformation of (x-3, y+1) shifts 3 units left and 1 unit up. Notice both of these undo the original "3 units right and 1 unit down" from earlier. So this is why we get back to the starting point. It's not a coincidence.
Therefore, transformation T and transformation S are inverse transformations of one another. They undo each other. It's like taking a step forward (transformation T) and then taking a step back (transformation S)
In terms of algebra, it's like how multiplication and division are inverses of each other.
As you can probably guess, there's nothing particularly special about (5,7). I chose two random numbers. Pick whatever two favorite numbers you want for x and y. Plug them into T(x,y) and then whatever that result is, plug it into S(x,y) to notice you should get back to your original choice of (x,y). I recommend GeoGebra as a useful tool to help with geometric transformations.

Shelby measured the volume of a cylinder and determined it to be 58.8 cm³. The teacher told her that she
was 4.98% too high in her determination of the volume. What is the actual volume of the cylinder?
The actual volume of the cylinder is 61.73 cm³
Percentage error is the error introduced in a measurement. The formula for the error is given as :
Error = Percentage error * measured volume
According to the question we have been given that
determined volume of cylinder = 58.8 cm³
Percentage error = 4.98%
thus, error = 4.98% * 58.8
= 0.0498 * 58.8
= ±2.93 cm³
The formula for the actual volume is given as
Actual volume = measured volume ± error
= 58.8 ± 2.93 cm³
As the error is high we will do addition we get
= 58.8 + 2.93 cm³
= 61.73 cm³
hence the actual volume is 61.73 cm³

O 23
Answer:
24
Step-by-step explanation:
Because 300 cookies / 38 cookies = 7.89,..
Then 7.89,... x 3 = 23.68,...
round to the nearest tenths= 24
In order to meet the demand for the bake sale, a total of 300 cookies will be prepared, requiring the use of precisely 24 fresh eggs.
To calculate how many eggs you need to make 300 cookies, set up a proportion based on the information given in the cookie recipe:
Number of eggs / Number of cookies = Constant ratio
Let the number of eggs needed for 300 cookies as "x."
So, x eggs / 300 cookies = 3 eggs / 38 cookies
Now, cross-multiply and solve for "x":
x * 38 = 3 * 300
38x = 900
x = 900 / 38
x = 23.6842
x ≈ 24
Therefore, you need 24 eggs to make 300 cookies for the bake sale.

I guess the result is needed again in slope-intercept form.
this is in general
y = ax + b
"a" being the slope, "b" being the y-intercept (y value when x = 0).
when a line is parallel to another line, this means they both have the same slope.
so, we can use the same "a" from the original line : -1
to get "b" we use the given point coordinates :
5 = -1×-3 + b = 3 + b
2 = b

Find the C-intercept and the n intercept
Answer:
C intercept is 800, n intercept is -3.3333...
Step-by-step explanation:
C = 240n + 800 is a linear equation (the graph is a line)
C-intercept is the point with the coordinates ( 0, C-intercept ) where the line C = 240n + 800 is intersecting the vertical C-axis and
n-intercept is the point with the coordinates (n-intercept, 0) where the line C = 240n + 800 is intersecting the horizontal n-axis.
Find the C-intercept:
n has to be 0 for our line to intercept the C-axis, so substitute n = 0 in our given equation
C = 240n + 800
C = 240·0 + 800
C = 800
Find the n-intercept:
C has to be 0 for our line to intercept the n-axis, so substitute C = 0 in our given equation
C = 240·n + 800
0 = 240·n + 800, subtract 800 from both sides
-800 = 240 ·n, divide both sides by 240
-800/240 = n
-3.(3) = n
