Is this graph a function?
This cannot be determined from this graph.
This is a function.
This is not a function.
Answers
Answer:
Sorry but.
Step-by-step explanation:
Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

identify an equation in point-slope form for the line perpendicular to y= 4x - 9 that passes through (-5, 3)
Answers
Hello there!
The slopes of perpendicular lines are opposite reciprocals. It means we take the slope of the given line, flop it over and make it negative.
And then just plug in the points:
y-y1=m(x-x1)
y-3=-1/4x-(-5)
y-3=-1/4x+5

Answer:
sum = 1
Step-by-step explanation:
The method of partial sums has you look at sums of various numbers of terms of the series to see if there is a pattern that suggests either divergence or a limit. Here, the partial sums suggest the series sum is 1.
__
In the attachment, we have computed sums of 1 term, 10 terms, 100 terms, and so on up to 10^8 terms. These sums seem to approach the value 1.
Individual terms get small faster than for a harmonic series, which his known not to converge, but more slowly than a quadratic series. Large numbered terms are approximately proportional to n^-(3/2).
_____
You can actually compute the sum exactly, without reference to partial sums. Each term of the sum can be rewritten as ...
[tex]\dfrac{1}{(n+1)\sqrt{n}+n\sqrt{n+1}}=\dfrac{1}{\sqrt{n(n+1)}(\sqrt{n+1}+\sqrt{n})}\\\\=\dfrac{\sqrt{n+1}-\sqrt{n}}{\sqrt{n(n+1)}}=\dfrac{1}{\sqrt{n}}-\dfrac{1}{\sqrt{n+1}}[/tex]
Then successive terms will cancel the intermediate fractions. So, for example, the sum of the first 3 terms is ...
(1/√1 -1/√2) +(1/√2 -1/√3) +(1/√3 -1/√4) = 1 -1/√4
This means the given sum will evaluate to ...
1 -1/√∞ = 1 -0 = 1 . . . sum of the infinite series

1. 15
2. 75
3. 105
4.150
Answers
due to my knowledge its 75 because it is.
Step-by-step explanation:
first I thought the angles at Q and P are right angles (90 degrees). but the last part tells me they are not.
so, all the "perpendicular" answers are out.
answer 1 and 2 are all correct but I would pick 2, because it had the most detail that's true.
and since these 2 lines are parallel, the must have the same angles with the crossing line.
therefore, when the angle RQS is 75 degrees, then the angle TPU is also 75 degrees.

Step-by-step explanation:
Set up a proportional ratio: inch/cm = inch/cm

Answers
Average: about 87%
Her english grade affects her average because it is the lowest out of all of the grades which brought her average grade down.
not sure about this: To bring her average higher, she should probably try more in english or study. (not sure about this one)
Step by Step:
Add up all of her scores:
86 + 72 + 93 + 87 + 93 + 100 + 80
it equals 611
Since we added up 7 scores, we divide 611 by 7
611 divided by 7 is 87.285...
So her average is about 87%

Subtract both sides by 17:
2/3x + 17 - 17 ≥ 29 - 17
2/3x ≥ 12

Answers
Answer:

Step-by-step explanation:
His salary doubled (x2), so you can eliminate B & C because they are + & -. You can eliminate A because that would represent his current salary. So, that leaves $2x.
Why? because using process of elimination, you know it can’t be subtraction or addition because it uses the key word doubled, meaning you’d have to multiply leaving you with 2x.
0.5y+7=5(0.2+1.5y) someone please help I got y=1.36 but its wrong
Answers
Answer:
y= 6/7
Step-by-step explanation:
0.5y + 7 = 5( 0.2 + 1.5y )
Get rid of the brackets first
0.5y + 7 = 1 + 7.5y
Move the like terms
0.5y + 7 - 7.5y = 1
0.5y - 7.5y = 1 - 7
Collect the like terms
-7y = -6
Divide both sides by -7 to get y on its own
y= -6/-7
A negative number divided by a negative number gives a positive number so
y = 6/7
Answer:
y=6/7 or 0.857 aprox.(0.86)
Step-by-step explanation:
[tex]0.5y+7=5(0.2+1.5y)[/tex]
[tex]0.5y+7=1+7.5y[/tex]
