Answer:

Point form (2.1)

Equation form: x=2,y=1

Answer:

(2, 1 )

Step-by-step explanation:

y = 6x - 11 → (1)

- 2x - 3y = - 7 → (2)

Substitute y = 6x - 11 into (2)

- 2x - 3(6x - 11) = - 7 ← distribute parenthesis and simplify left side

- 2x - 18x + 33 = - 7

- 20x + 33 = - 7 ( subtract 33 from both sides )

- 20x = - 40 ( divide both sides by - 20 )

x = 2

Substitute x = 2 into (1)

y = 6(2) - 11 = 12 - 11 = 1

solution is (2, 1 )

If Point P is between Q and R and QP = 16 and Qr = 52. What is the length of PR?
Dimas [21]
1) Here, QR = QP + PR

52 = 16 + PR

PR = 52 - 16 = 36

In short, Your Answer would be Option C

2) Slope of mentioned line:
m = (5+5) / (0-4)
m = 10/-4
m = -5/2

Parallel lines have same slope so it would be -5/2 as well

In short, Your Answer would be Option B

Hope this helps!

It is 42 1/2 miles from Eaton to Baxter and 37 4/5 miles from Baxter to Wellington. How far is it from Eaton to Wellington if yo
mina [271]
All you need to do is add the miles from Eaton to Baxter and from Baxter to Wellington to get your answer...

42 + 37 = 79 

Now we need to add the fractions 

\frac{1}{2} +  \frac{4}{5} = ...


To add we need a common denominator. 
2 and 5 can both go into 10, so that will be a our common denominator. 
Now you have... 
\frac{5}{10} + \frac{8}{10} = \frac{14}{10}
which is equal to 1 \frac{2}{5}
add that to the 79 we got earlier ...

The toal and final answer is 80 \frac{2}{5} miles !
Hope I helped and remember to vote this as the brainliest answer ! :)

Answer:

I think the answer is 42

Step-by-step explanation:

So, with all of that, the equation will now be = 5^2 + (2 * 8) / 2 + (3 * 3)

So next, you can use PEMDAS. After that, u should get ur answer of 42.

Work:

5^2 + (2 * 8) / 2 + (3 * 3)

5^2 + 16 / 2 + 9

25 + 16 / 2 + 9

25 + 8 + 9

25 + 17

= 42

Hope this helps :D!!

Can someone help me with this? Preferably with an explanation on how to actually figure this out. Thank you!
zhannawk [14.2K]

Answer:

2^-4, 1/16, (1/2)^4

There is a rule with exponents, if you are dividing two exponents you subtract the first exponent from the other to simplify it, also meaning it's equivalent.

So in this case 5-9 = 2^-4

The others were found by evaluation.
