algebra questions

Answer 1

correct! :)

Answer 2

yep :)

Answer 3

yep :)

Answer 4

independent variable for h(x)
^ x

Answer 5

So A then

Answer 6

yep :)

Answer 7

correct :)

Answer 8

correct :)

Answer 9

y = mx + b
when b = y-intercept
where do you see the line cross the y-axis?

Answer 10

on the 1 so would that make it C since C has 1 in the answer?

Answer 11

yep :)

Answer 12

B. y = 1/4x -> y = 1/4 x + 0
^ has y-intercept of 0
A. y = x - 7
^ has y-intercept of -7
is -7 less than 0 ?

Answer 13

yes, you're right so it would be A

Answer 14

yep :)

Answer 15

yep :)

Answer 16

correct! :)

Answer 17

maybe another hour or two :)

Answer 18

ok :)

Answer 19

rental fee of $25.00 plus $.50 per mile
y = 0.5x + 25
^

Answer 20

yep :)

Answer 21

well I formatted it that way
it could also look like y = 25 + 0.5x
^ but this would still be the y-intercept

Answer 22

plug in x = 122 into y = 0.5x + 25

Answer 23

Oh 86, so it's A

Answer 24

yep :)

Answer 25

A would be correct :)

Answer 26

since the equation was h = -1/3 x + 69
then the rate would be ^

Answer 27

the water level depends on the time

Answer 28

monthly fee would be the independent variable

Answer 29

range has to do with h
h can't be greater than 69

Answer 30

yep :) it's B

Answer 31

Trisha's Car Loan
Number of Payments = 6, 10, 14, 18
Balance (dollars) = 6,720, 6080, 5,440, 4800

balance is dependent on number of payments

Answer 32

correct :)

Answer 33

6720 - 6080 = 640
10 - 6 = 4
640 / 4 = 160
so A would be correct :)

Answer 34

sure :)

Answer 35

Or actually I'll try it on my own right now and then if I still don't get at least 80% I will try it with your help :) Sounds like a better idea I think.

Answer 36

yup sure :)

Answer 37

monthly fee

Answer 38

number of payments

Answer 39

number of hours
when in doubt, time is always the independent

Answer 40

ummm... hmm...
A or B
go with B :/

Answer 41

D

Answer 42

A

Answer 43

C

Answer 44

A

Answer 45

600 = 25x + 150
solve for x
x = 18
A. 18

Answer 46

ok :)

Answer 47

y= mx + b
m = 3.95
b = 65

Answer 48

I'm not sure if that would make it A or B

Answer 49

B would be correct :)

Answer 50

idk graph but ok xD

Answer 51

D

Answer 52

yep :)

Answer 53

"a total of 124 adult and student tickets" --> a + s = 126

"each adult ticket sold for $5 and each student ticket sold for $3"
"for a total of 426" --> 5a + 3s = 426

Answer 54

yep :)

Answer 55

b + g = 58 -> b = -g + 58
b - g = 14 -> b = g + 14
since b = b
g + 14 = -g + 58
solve for g

Answer 56

g + 14 = -g + 58
2g = 44
g = 22

Answer 57

g = girls
g = 22

Answer 58

lol it's fine :)

Answer 59

where do the two lines intersect?

Answer 60

about 37 I think which would make it A?

Answer 61

yep :)

Answer 62

Length is 3 less than twice the width
L = - 3 + 2W
L = 2W - 3

P = 2W + 2L
P = 36
so 2W + 2L = 36

Answer 63

y = mx + b
m = 4.95 per premium movie
b = 60 per month
y = 4.95x + 60

Answer 64

30 min to hour maybe

Answer 65

ok :)

Answer 66

idk this one, sorry :/

if I were to guess...
40x = 56(x-2)
40x = 56x - 112
16x = 112
x = 7
40*7 = 280 <-

Answer 67

40x = 56(x-2)
40x = 56x - 112
16x = 112
x = 7 <-

Answer 68

(13, 30)
because both tables contain that ordered pair

Answer 69

when x = 752
the other two values in the graph are the same
so C

Answer 70

plug in x = 3 when 56(x-2) and simplify

Answer 71

I gtg :/

Answer 72

maybe a couple more... but quick

Answer 73

56

Answer 74

40*3 = 120

Answer 75

bottom left one

Answer 76

B I think

Answer 77

you're welcome and you too :)
