Answer:

y=x+2

Step-by-step explanation:

4-2y=-2x

Divide everything by 2.

2-y=-x

Switch to y=mx+b form.

-y=-x-2

Multiply everything by +1.

y=x+2

Answer:

5+2x+x+2=34

7+3x=34

7-7+3x=34-7

3x=27

3x/3=27/3

x=9

5+2x=AS

5+(2*9)=AS

5+18=AS

23=AS

Answer:

132.50

Step-by-step explanation:

3/5b = 79.50

b = (79.50) / (3/5)

b = 79.50 * 5/3

b = 397.50/3

b = 132.50

132.50 is the total bill

Answer:

y = 136

Step-by-step explanation:

the line is 180 degrees so

180-44 = 136 degrees

Answer:

y=136

Step-by-step explanation:

x=44 y=136

44+136=180

Answer:

Simple springs obey Hooke's Law. Hooke's Law states that the force on a spring is proportional to it's displacement from it's resting length:

F = -k*x

Where F is the force, x is how far the string is stretched or compressed, and k is a proportionality constant called the spring constant. The negative sign is because the spring resists stretching.

In this case, we can solve for k using the first case:

(100N) = -k * (5cm)

k = ???

And plug that answer in to find x in the second case:

(360N) = -k * x

    This is a "Hooke's Law" problem: the restoring force required to compress or stretch a spring is proportional to the distance the spring is deformed.  You can figure solve it by setting up a proportion equation and then using the algebraic tool of cross multiplication to solve for the unkown "stretch".

1) set up the proportion equation

100  =  360

5           x

2) cross multiply to get a linear equation

100x = 5*360

3) solve for x

 100x = 1800

       x = 18

Answer:

The law: F=kx

Therefore,

180N = k * 5cm

k = 180÷5= 36N per cm

Using the known constant with the law,

270=36*x

x= 270 ÷ 36 = 7.5cm

Answer:

Step-by-step explanation:

Hi there!

∠SRQ = 162°

∠STR = 130°

∠RST = ?

Now;

∠SRQ = ∠RST+∠STR   [external angle is equal to the sum of opposite interior angles of triangle]

∠RST = ∠SRQ-∠STR

∠RST = 162°-130°

Therefore, the measure of ∠RST is 32°.

Hope it helps!

Answer:

-3(n + 2)= 15

Step-by-step explanation:

Based on this question, we know that the equation involves multiplication. Here we start our equation with -3!

Then it says "times the sum of a number and two" So let's just say the "number" is "n". The word "sum" means the answer to an addition problem, thus we know that we are adding "n" and 2. Let's put that in parenthesis!

-3(n+2)

And it says "is fifteen" which also means "equals to fifteen"

Therefore, the answer is:

-3(n + 2) = 15

Hope you find this useful :D

Answer:

47 mph

Step-by-step explanation:

1 day = 24 hours, so 2 days = 48 hours.

2274/48 (2274 miles per 48 hours, simplify!) This equals 47.375. Round it down to 47 mph.

This is assuming the car took no breaks.

Hope this helps!

r=35/25

r=1.4

substitution

r160=t*15

t=time

r=1.4

1.4*160=t*15

224=t*15/15

224/15=t

Answer:

y = -4/3x -9

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

8x+6y = -54

Subtract 8x from each side

8x+6y-8x = -8x-54

6y = -8x-54

Divide each side by 6

6y/6 = -8x/6 -54/6

y = -4/3x -9

Answer:

y = -4/3x - 9

Step-by-step explanation:

Putting this into 'y=mx+c' form:

i) Firstly, make it only y on the LHS:

6y = -8x-54

ii) Secondly, making the 'y' have a co-efficient of 1. This can be done by dividing both sides by 6:

6y/6 = -8x/6 - 54/6

y = -4/3x - 9

Hence,

y = -4/3x - 9
