Find the equation of the line through (9,-7) that is perpendicular to the line y = -x/2 - 2
Answer:
[tex]y=2x-25[/tex]
Step-by-step explanation:
Hi there!
Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept (the value of y when x=0)
Perpendicular lines always have slopes that are negative reciprocals, such as 2 and -1/2, 3/4 and -4/3.
1) Determine the slope (m)
[tex]y = \displaystyle -\frac{x}{2} - 2[/tex]
Rewrite the given line:
[tex]y = \displaystyle -\frac{1}{2}x - 2[/tex]
Now, we can clearly identify the slope to be [tex]\displaystyle-\frac{1}{2}[/tex]. Because perpendicular lines always have slopes that are negative reciprocals, the slope of the line we're currently solving for is therefore 2. Plug this into [tex]y=mx+b[/tex]:
[tex]y=2x+b[/tex]
2) Determine the y-intercept (b)
[tex]y=2x+b[/tex]
Plug in the given point (9,-7) and solve for b:
[tex]-7=2(9)+b\\-7=18+b\\b=-25[/tex]
Therefore, the y-intercept is -25. Plug this back into [tex]y=2x+b[/tex]:
[tex]y=2x+(-25)\\y=2x-25[/tex]

What had the biggest effect on the earths orbit about the sun , explain.
Answer:
The Earth's orbit makes a circle around the sun. At the same time the earth orbits around the sun, it also spins. In science, we cal that rotating on its axis. Since the earth orbits the sun AND rotates on its axis at the same time we experience seasons, day and night, and changing shadows throughout the day.

Given y = x + 1 Calculate y if x = 3. y is a natural number
Answer:
y = 4
Step-by-step explanation:
If 3 is x than you can substitute x for 3. y = 3 + 1. Then when you add y = 4
y = x+1
y = 3+1
y= 4
that's how you solve it... Good luck

Find the missing angle and name the other three given angle.
PQR=___
Name:___________
________________
________________
Answer:
Step-by-step explanation:
The angles between the parallel sides add up to 180 degrees.
So 180-70 = 110 degrees.
▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄
Let,
The unknown angle measure be x°.
We know that,
Sum of all angles of a Quadrilateral measures 360°.
So,
⇒∠QPR + ∠PSR + ∠SRQ + ∠RQP = 360°
⇒ 120° + 60° + 70° + x° = 360°
⇒ 180° + 70° + x° = 360°
⇒ 250° + x° = 360°
⇒ x° = 360° - 250°
⇒ x° = 110°
Therefore, the names of the angles & their values will be,
⇒∠QPR = 120°
⇒∠PSR = 60°
⇒∠SRQ = 70°
⇒∠RQP = 110°

PLEASE HELP!!! How does the multiplicity of a zero affect the graph of the polynomial function?
9514 1404 393
Answer:
2, 4, 61crossStep-by-step explanation:
Consider a zero at x=1.
If it has multiplicity 1, the corresponding factor is (x -1). Now consider the sign of that factor for x = 1.1. The value is (1.1 -1) = 0.1, a positive number.
When the value of x is 0.9, the factor is (0.9 -1) = -0.1, a negative number.
This tells you that values to the left of a zero make the factor(s) associated with that zero be negative. For x-values to the right of the zero, the factor(s) will be positive.
If the multiplicity is even, the product of those factors is positive on either side of the zero. (A negative number to an even power is a positive number.) That is, the graph will not change sign from one side of an even-multiplicity factor to the other. At an odd-multiplicity factor, the graph changes sign.
__
For the problem at hand, the only even-multiplicity factor is (x -1), so the graph will not change sign at x=1. It will touch the axis (be tangent to the x-axis), but will not cross. The other zeros have odd multiplicity (1 or 3), so the graph will change sign there.
It is worthwhile to note that the higher the multiplicity, the "flatter" the graph is at the zero. You can see this in the attachment by comparing the shape of the graph at x=6 with the shape at x=2 (also an upward zero crossing).
_____
Additional comment
You may wonder why the curve is below the x-axis at x=1 when the product of the factors in that neighborhood is always positive. The reason is that there are an odd number of zeros to the right of x=1, so the product of those factors is negative.
If 4/5 of the population of a certain town is
considered to be middle class and the population
of the town is 2,000, how many people are
considered middle class?
Hi! I'm happy to help!
Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)
2,000×4
8,000
8,000/5
Fractions are just a different way of putting division, so we can change this to a division problem:
8,000÷5=
1,600
1,600 of the people are middle class.

How can you get 3/3 -1/6?
9514 1404 393
Answer:
5/6
Step-by-step explanation:
Addition or subtraction of fractions requires a common denominator. The value 3/3 can be multiplied by 2/2 to give 6/6, which has the same denominator as the other fraction.
[tex]\dfrac{3}{3}-\dfrac{1}{6}=\dfrac{3\cdot2}{3\cdot2}-\dfrac{1}{6}\\\\=\dfrac{6}{6}-\dfrac{1}{6}=\dfrac{6-1}{6}=\boxed{\dfrac{5}{6}}[/tex]

b. Slope: 125/2
Point-slope form:
y-400 = 125/2(x-8)
y = 125/2+392
e. 767 consumers
Step-by-step explanation:
b. The slope is 125/2
Point-slope form:
Slope: 125/2 and point (8,400)
y-y=m(x-x)
Point slope form:
y-400=125/2(x-8)
y = 125/2 x + 392
y = (125/2)(6) + 392
y = 767

Find the slope of the line
Answer:
Slope = -3
Step-by-step explanation:
Answer:
Slope is -3
Step-by-step explanation:
Find two points on the graph where the line hits both corners of the graph first. ( The line has to go through a corner )
Two points on the graph: ( -2,6 ) and ( 2, -6 )
The first values are X-values ( -2, 2 ) It does left to right
The second values are Y-values ( 6,-6 ) It goes up and down
So to find the slope of a line you get two points and you do this formula
( y2-y1 ) / ( x2-x1 )
So that means
( -6 - 6 )
------------- = -12

Answer:
a) slope = -765 jobs per year
b) j = -765y +1582855 . . . . jobs in year y
c) 38,320 jobs in 2019
Step-by-step explanation:
a) We can define the variables y and j to represent the year number and the number of jobs, respectively. Then we are given 2 points:
(y, j) = (2012, 43675) and (2017, 39850)
The slope of the relation is ...
m = Δj/Δy = (39850 -43675)/(2017 -2012) = -3825/5 = -765
__
b) Using the point-slope form of the equation of a line, we can model the relation between years and jobs as ...
y -k = m(x -h) . . . . . . . line with slope m through point (h, k)
For m = -765 and (h, k) = (2012, 43675), the model gives ...
j -43675 = -765(y -2012)
j = -765y +1582855 . . . . . . . rearrange to slope-intercept form
__
c) For y = 2019, the number of jobs is modeled to be ...
j = -765(2019) +1582855 = -1544535 +1582855
j = 38,320 . . . . . jobs in 2019
_____
Additional comment
Quite often for problems of this sort, we let the time variable represent "years after <some reference year>". Here, it would be convenient to use 2012 as the reference year. The the equation would be j = -765y +43675, and the "j-intercept" would have the sensible value of 43675 at "year 0" (or 2012).
The equation we show is technically correct, but has no meaning for year values less than 2012. Especially, we know for sure there were not 1.6 million jobs in information in Indiana at the beginning of the Common Era. Indiana didn't exist until 1816.
