Answer:

y = 5/3x - 10

Step-by-step explanation:

5x - 3y = 15\\-3y = -5x + 15\\y = 5/3x - 5

that means the slope of the new line also has to be 5/3 because parallel lines have the same slope.

put it in point-slope form:

y - -5 = 5/3(x - 3)

y + 5 = 5/3x - 5

y = 5/3x - 10

Someone please help me on number 3 and if the others are wrong please let me know ITS MULTI STEP EQUATION COMBINING LIKE TERMS
weeeeeb [17]

Answer:

#1: x = 3; #2 c = 1/2; #3 = x = 22; #4 is correct (x = -8)

Step-by-step explanation:

for the first equation everything was right until 22x = 66

after

22x = 66

you must divide everything by 22

x = 3

that is for #1

for the second equation you copied down the question wrong

the negative is still there

6c - 8 - 2c = -6

combine 6c and -2c

4c - 8 = -6

the negative remains on the 8

add 8 to both sides

4c = 2

divide 4 to both sides

c = 2/4 or just 1/2

for the third equation you must first combine like terms

-3x + 25 + x + 21 = 2

combine -3x and x & 25 and 21

-3x + x = -2x

25 + 21 = 46

-2x + 46 = 2

then subtract 46 from both sides

-2x = -44

now divide both sides by -2

x = 22

that is your answer

number four should be correct

Mira bought $500 of Freerange Wireless stock in January of 1998. The value of the stock is expected to
Alexus [3.1K]

Answer:

2002

Step-by-step explanation:

The main topic of the question is compound interest.

If the percentage increase is 7.5%. Then the decimal multiplier would be 1.075. The 1 in front of the decimal represents the increase. 7.5 in decimal form is 0.075, so we just add the two together to get our decimal multiplier.

Now we do trial and error to see when we reach $700. After we get at least $700, we count how many times we multiplied $500 by the decimal multiplier and onwards to figure out the number of years it took and then add that to 1997. We add it to 1997 because the cost of the Freerange Wireless stock must have also been $500 at the end of 1997. The beginning of 1998 is the same as the end of 1997.

1) 500 x 1.075 = $537.50

2) 537.50 x 1.075 = $577.81

3) 577.81 x 1.075 = $621.15

4) 621.15 x 1.075 = $667.74

5) 667.74 x 1.075 = $717.8205

1997 + 5 = 2002

The value of Mira's stock will reach $700 by the end of 2002 because if we know that she used $500 at the beginning of 1998, that also means the cost of the Freerange Wireless stock was $500 at the end of 1997.

I hope this helps.
