Question

Does this look correct, question in comments?

Answer 1

Looks correct to me

Answer 2

Both C and D are correct. Nice work.

Answer 3

Thank you!!

Answer 4

Is this one also correct?

Answer 5

@samanthagreer and @jim_thompson5910

Answer 6

yes

t = 8.75/v
t = 8.75/7 ... we have v = 7 volunteers
t = 1.25 ... which means it takes 1.25 hours

Answer 7

Thank you!

Answer 8

no problem

Answer 9

I think this is one answer but i'm not sure about the others

Answer 10

It might help to plot the points. You'll hopefully be able to see where the line of symmetry is

Answer 11

Ok

Answer 12

I used geogebra to plot the points
http://prntscr.com/c7km07

Answer 13

So the line of symmetry would be -.5, which is not an answer

Answer 14

yes x = -0.5 is the line of symmetry. So it's close to what B is saying, but off by a sign.

Answer 15

A is false because it's actually increasing (not decreasing)

D is false because the coordinates need to be swapped to be true

Answer 16

only C is true

Answer 17

Thank you!

Answer 18

glad to be of help

Answer 19

Is this one correct?

Answer 20

I'm sorry this is a final quiz and i'm trying to get as much possible correct

Answer 21

x = amount of time Reynaldo takes to do the job all alone
y= amount of time Ruben takes to do the job all alone
z = amount of time both people take if they work together

Answer 22

x = 6
y = unknown
z = 3.5

solve for y

\[\Large \frac{1}{x}+\frac{1}{y}=\frac{1}{z}\]

\[\Large \frac{1}{6}+\frac{1}{y}=\frac{1}{3.5}\]

Answer 23

C) 2.5 is not correct

Answer 24

So y=8.4

Answer 25

better

Answer 26

Is this one correct?

Answer 27

B is cut off. I can't see it

Answer 28

D is not correct. y is approaching 0 as x heads to infinity

Answer 29

yeah it's B. As x goes off to +infinity or -infinity, y is slowly approaching y = 3

Answer 30

Is this correct?

Answer 31

almost. There's one thing missing

Answer 32

That it is translated up 4?

Answer 33

yes

Answer 34

y = x^2 .... parent function

y = -x^2 .... flip over x axis

y = (-1/2)x^2 ... compress by a factor of 1/2

y = (-1/2)x^2 + 4 ... shift up 4 units

Answer 35

Can you help me with this question?

Answer 36

The avenues in a particular city run north to south and are numbered consecutively with 1st Avenue at the western border of the city. The streets in the city run east to west and are numbered consecutively with 1st Street at the southern border of the city. For a festival, the city is not allowing cars to park in a rectangular region bordered by 5th Avenue to the west, 9th Avenue to the east, 4th Street to the south, and 6th Street to the north. If x is the avenue number and y is the street number, which of the following systems describes the region in which cars are not allowed to park?

Answer 37

what's the midpoint of x = 5 and x = 9 ?

Answer 38

I'm not sure

Answer 39

add up the values and then divide by 2

Answer 40

Then 7

Answer 41

so we'll have x-7 because we want to shift the center 7 units to the right

Answer 42

Ok

Answer 43

what's the midpoint of y = 4 and y = 6?

Answer 44

So it would be D?

Answer 45

yes

Answer 46

Ok thank you so much!

Answer 47

sure thing

Answer 48

Is this correct?

Answer 49

@jim_thompson5910

Answer 50

yes it is

Answer 51

How do I do this one?

Answer 52

Plug each corner point into the P(x,y) function. The point that yields the largest output is the answer

Answer 53

or you can just plug in the answer choices given

Answer 54

Is this correct?

Answer 55

yes it is

Answer 56

How would I do this question?

Answer 57

@jim_thompson5910

Answer 58

similar triangles have congruent corresponding angles

angle D = angle A
angle D = 28 degrees

Answer 59

triangle ABC is similar to triangle DEF

A and D are the first letters of ABC and DEF respectively

so that's why A and D correspond together

Answer 60

Thank you so much!

Answer 61

no problem

Answer 62

How would I do this question?

Answer 63

hint: the triangles are similar, so

angle H = angle T
angle O = angle A
angle P = angle G

Answer 64

So it would be B and D?

Answer 65

Because Angle H = Angle T and Angle P = Angle G

Answer 66

correct on both

Answer 67

Anything else?

Answer 68

No right because Angle P doesn't = Angle T

Answer 69

And Angle G doesn't equal angle H

Answer 70

only B and D would be answers. The others are false

Answer 71

How would I do this question?

Answer 72

@jim_thompson5910

Answer 73

Nevermind I got it

Answer 74

Yes you're using the idea that a^2+b^2 = c^2

Answer 75

How do I do this problem @TheSmartOne?

Answer 76

I don't know the equation I would use

Answer 77

@.Sam. Do you know how to do this problem?

Answer 78

Is this correct? @.Sam. @TheSmartOne
