+14m +14m (add 14 on both sides)

_____________

__ ___ (divide 16 on both sides)
16 16
m = 0.75
Answer:
m = 3/4
Step-by-step explanation:
7 - 14m = 2m - 5 (given)
7 + 5 - 14m = 2m - 5 + 5 (addition poe)
*add 5 to both sides to cancel -5 out*
12 - 14m = 2m
12 - 14m + 14m = 2m + 14m (addition poe)
*add 14m to both sides to cancel -14m* out*
12 = 16m
12/16 = 16m/16 (division poe)
*divide by 16 on both sides to cancel out the coefficient*
12/16 = m
m = 12/16 (symmetric property)
*mirror to the other side*
m = 12÷4/16÷4 (division poe)
*divide the numerator and denominator by its greatest common factor*
m = 3/4

Hector has $590 in his account. He earned $15 per hour for x hours. Jeremy has $545 in his account. He earned $20 per hour for x hours. They both worked the same number of hours and now have the same amount of money. What is the number of hours that each person worked? Write and solve an equation.
Answers
Answer:
equation = 590 + 15x = 545 + 20x
No. of hours worked = 9
Step-by-step explanation:
Given that both worked for same number of hours
and
Jeremy worked for for x hours
it meant that Hector also worked for x hours(it is also mentioned same in the problem)
now that we know the number of hours worked in form of x
lets find
total money in their account if they worked for x hours
___________________________________________
For Hector
Money in Hector's account = $590
Earning for Hector in 1 hour = $15
Earning for Hector in x hour = x*Earning for Hector in 1 hour = $15x
Total money in with Hector after x hours of work
= Money in Hector's account + Earning for Hector in x hour = $590 + $15x
Similarly
For Jeremy
Money in Jeremys account = $545
Earning for Jeremy in 1 hour = $20
Earning for Jeremy in x hour = x*Earning for Jeremy in 1 hour = $20x
Total money in with Jeremy after x hours of work
= Money in Jeremy's account + Earning for Jeremy in x hour = $545 + $20x
Given that they same amount of money
thus
$590 + $15x = $545 + $20x
$sign gets cancelled from both sides
590 + 15x = 545 + 20x Thus, we got the required equation
=> 590 - 545 = 20x - 15x
=> 45 = 5x
=> x = 45/5 = 9
Thus, both of them worked for 9 hours

Answer:
[tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex]
Step-by-step explanation:
The formula is actually d= [tex]\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2}}[/tex]. Now first, we have to find points A and C.
Point A is (1,2) and Point C is (-1,0).
Now we have to substitute the values in. That would make it d =[tex]\sqrt{(-1-1)^{2} + (0-2)^{2}}[/tex].
To simplify the parentheses, it would get to d= [tex]\sqrt{(-2)^{2}+(-2)^{2} }[/tex].
To simplify the exponents, it would get to d = [tex]\sqrt{4+4}[/tex].
To simplify the square root, it would get to d = [tex]\sqrt{8}[/tex].
So the answer is either [tex]2\sqrt{2}[/tex] or [tex]\sqrt{8}\\[/tex].

QUESTION 1: In Exercises 5–8, use the method illustrated in Example 2 to determine moving averages by subtraction and addition. Determine the 6-day SMA for the ten consecutive trading day closing prices for SunEdison Inc. Listed below. $2.65, $2.63, $2.70, $2.63, $2.50, $2.65, $2.66, $2.56, $2.52, $2.37 * 5 points
Answers
Answer:
The 6-day SMA for the ten consecutive trading day
= $2.63, $2.63, $2.62, $2.59, $2.54
Step-by-step explanation:
Determining the 6-day SMA for the given values
using the addition and subtraction methodology
First we will determine the Average closing prices for 1 - 6 days
= [tex]\frac{2.65 + 2.63 + 2.70 + 2.63 + 2.5 + 2.65}{6}[/tex] = 15.76 / 6 = $2.626 ≈ $2.63
next we have to determine the SMA for days 2 - 7
= 2.63 - [tex]\frac{2.65}{6} + \frac{2.66}{6}[/tex] = [tex]\frac{15.77}{6}[/tex] ≈ $2.63
SMA for days 3 - 8
= 2.63 - [tex]\frac{2.63}{6} +\frac{2.56}{6} = \frac{15.70}{6}[/tex] ≈ $2.62
SMA for days 4 - 9
= 2.62 - [tex]\frac{2.70}{6} + \frac{2.52}{6} = \frac{15.52}{6}[/tex] ≈ $2.59
SMA for days 5 - 10
= 2.59 - [tex]\frac{2.63}{6} + \frac{2.37}{6} = \frac{15.26}{6}[/tex] ≈ $2.54
Hence the 6-day SMA for the ten consecutive trading day
= $2.63, $2.63, $2.62, $2.59, $2.54

Line $1$ represents the graph of $3x + 4y = -14$. Line $2$ passes through the point $(-5,7)$, and is perpendicular to line $1$. If line $2$ represents the graph of $y=mx +b$, then find $m+b$.
Answers
Answer:
15
Step-by-step explanation:
First, solve for Line 1
3x + 4y = -14
move the x to the right of the equation
4y = -3x - 14
divide the whole equation by 4
y = -3/4x - 14/4
Line 1 is y = -3/4x - 7/2
Then, solve for Line 2
Since Line 2 is perpendicular, change the sign of the slope of Line 1 and then get the reciprocal of that.
-3/4 to 3/4 to 4/3
4/3 is the slope of Line 2.
Now, we want to find what the b of the equation is, so we can plug in our x (-5) and our y (7) into the y=mx+b equation to find b. The 4/3 is the m or the slope.
y = mx + b
plug in the y, m, and x into the equation
7 = (4/3)(-5) + b
multiply the m and x together
7 = -20/3 + b
add 20/3 to both sides so it will cancel out on the right of the equation and be added to the 7 on the left of the equation
41/3 = b
So, m = 4/3 and b = 41/3
Add them together and you get 45/3 or 15.

What is the slope of straight line?The slope of a straight line is the tangent of the angle formed by it with the positive x axis as the reference.
The negative slope indicates the rate of decrease while the positive shows the rate of increase.
The lines in the graph are passing through origin.
It implies that the y-intercept for all the lines is zero.
The slope-intercept equation of the line can be written as,
y = mx + c
Here c is the y-intercept.
When c = 0, the equation becomes as y = mx.
It implies that the for lines passing through origin, the slope of the line becomes the proportionality constant.
Now, from the given graph the line A is shown to be passing through (5, 1).
Then, the slope is given as,
m = (5 - 0)/(1 - 0) = 5
Hence, the line A in the given graph has constant of proportionality as 5.

Answer:
You can buy 6 pounds of apples.
Step-by-step explanation:
13 is an odd number, so we find the closest even number that doesn't go over 13. That number is 12. Then, we take 12 and divide it by 2, since $2 is how much a pound of apples cost. 12 divided by 2 is 6. So, our answer is 6 pounds of apples.
