Mathematics

Answer:

-7

Step-by-step explanation:

Equation: 2x - 4 = -18

First, add 4 to both sides:

2x = -14

Finally, divide both sides by 2:

x = -7

Check (optional):

2(-7) - 4 = -18

-14 - 4 = -18

-18 = -18 so this is correct

If you're confused about any of these steps, just let me know and I'll try to clear it up for you! :)

Given the points (–3,k) and (2,0), for which values of k would the distance between the points be √34 ?
myrzilka [38]

Answer:

The values of k are 3 and -3

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

(-3,k)\\(2,0)  

d=\sqrt{34}

substitute

\sqrt{34}=\sqrt{(0-k)^{2}+(2+3)^{2}}

\sqrt{34}=\sqrt{(-k)^{2}+(5)^{2}}

\sqrt{34}=\sqrt{k^{2}+25}

squared both sides

34=k^{2}+25

k^{2}=34-25

k^{2}=9

k=(+/-)3

ICE Princess25 [194]

Answer:

112.34

Step-by-step explanation:

The 2nd digit after the decimal point is in the hundredths position.

• If the digit following is ≥ 5 then round up

• If the digit following is < 5 then leave digit as it is

here the digit following the 3 in the hundredths position is 9 so round up

112.3398 ≈ 112.34 ( to the nearest hundredth )
