Both lines on the graph show proportional relationships. You want to choose the table that has both of its points on the same line. That would be the 4th one:

... x 3 5

... y 6 10

i got the same answer as the other dude but i dont know if i did it the right way. i multiplyed each number opisite from the other so 10 x 3 and 6 x 5 and they both equaled 30 so i guess.?? tell me if i solved this right. probbaly not

Answer: Your answer is c

Step-by-step explanation: The first thing you can do is add the two equations together to cancel out x

5x-2y=3

-5x+4y=9

added them together will get us 2y=12, from here divide 2 and get y=6

Plug 6 into the first equation and solve for x.

5x-2(6)=3

5x-12=3, add 13 to the other side

5x=15, divide 5 and get the answer

x=3

1. & 2. In the diagram below, points A, B, and C are collinear. Answer each of the following questions. The figure shown bel

Lana71 [14]

Answer:

a) $\overline{AB}$ = 8 in

b) When the length of AC = $6\frac{1}{2}$ in. and BC = $3\frac{1}{2}$ in. $\overline{AB}$ = 10 in

c) When the length of AB = 10.2 in. and BC = 3.7 in. $\overline {AC}$ = 6.5 in

d) When the length of AB = $4\frac{3}{4}$ in. and BC = $3\frac{1}{4}$ in. in. $\overline {BC}$ = $1\frac{1}{2}$ in

Step-by-step explanation:

a) When the length of AC = 5 in. and CB = 3 in. we have;

The length of $\overline {AB}$ = AC + CB (segment addition postulate)

Therefore;

$\overline{AB}$ = 5 in. + 3 in. = 8 in.

b) When the length of AC = $6\frac{1}{2}$ in. and BC = $3\frac{1}{2}$ in. we have;

The length of $\overline {AB}$ = AC + CB (segment addition postulate)

Therefore;

$\overline{AB}$ = $6\frac{1}{2}$ in.+ $3\frac{1}{2}$ in. = 10 in.

c) When the length of AB = 10.2 in. and BC = 3.7 in. we have;

The length of $\overline {AC}$ = AB - BC (converse of the segment addition postulate)

Therefore;

$\overline {AC}$ = 10.2 in.+ 3.7 in. = 6.5 in.

d) When the length of AB = $4\frac{3}{4}$ in. and BC = $3\frac{1}{4}$ in. in. we have;

The length of $\overline {BC}$ = AB - AC (converse of the segment addition postulate)

Therefore;

$\overline {BC}$ = $4\frac{3}{4}$ in. - $3\frac{1}{4}$ in.= $1\frac{1}{2}$ in.

One leg of a right triangle measures 6 inches. The remaining leg measures 6 StartRoot 3 EndRoot inches. What is the measure of t

Usimov [2.4K]

Answer:

∅ = 30°

Step-by-step explanation:

given data

side 1 = 6 inches

side 2 = $6\sqrt{3}$ inches

to find out

angle opposite the leg that is 6 inches long

solution

we will use pythagoras theorem that is express as

hypotenuse² = perpendicular² + base² .......................1

put here value and we get hypotenuse

hypotenuse² = 6² + ( )²

solve it we get

hypotenuse² = 144

hypotenuse = 12 inches

now we apply here sin∅ that is

sin∅ = $\frac{perpendicular}{hypotenuse}$ ................2

put here value and we get

sin∅ = $\frac{6}{12}$

∅ = $sin^{-1}(0.5)$

solve it we get

∅ = 30°

Laura’s credit card has an APR of 12.04%, and it computes finance charges using the daily balance method and a 30-day billing cy

Fynjy0 [20]

Finance charge is equal to:
daily balance*A*P*R*billing cycle/365
db 0.1204 30/365 = 5.71
db = 577.01 (I am rounding every answer, and keeping the number in my calculator, things won't work out exactly if you calculate using my numbers)Manipulate the formula for mean:
average = total/amount
577.01 = total/30
total over 30 days = 17,310.22Set up an equation with our information:
606.40x + 55.25(30-x) = 17,310.22
551.15x = 16,652.72
x = 28.4

The balance was $606.40 for 28 days, so she paid on the 29th.
