(-6,-1) is the answer to your question.
WINSTONCH [101]3 years ago
5 0

If we add theses 2 equations we eliminate the y terms ( -11y + 11y = 0):-


so adding we get


13x = -78

x = -6


Substitute x = -6 in the first equation:-


10(-6) = -71-11y

11y = -71 + 60 = -11

y = 1


So the solution to the system of equations is x = -6,y = 1

Solve (u+6)^2+4=52 , where u is a real number.
Ugo [173]

Answer:

The value of u are,

0.93, -12.93

Step-by-step explanation:

It is given an expression in variable u

(u + 6² + 4 = 52

<u>To find the solution of given expression</u>

(u + 6)·² + 4 = 52

(u + 6)²  = 52 - 4

(u + 6)² = 48

u + 6 = √48

u + 6 = ±6.93

u =  ±6.93 - 6

u = 6.93 - 6  or u = -6.93 - 6

u = 0.93 or u = -12.93

How can you make your answer (41-13i)/(25) into a+bi form?
KengaRu [80]

Hello, do you know that for any a, b and c real numbers with c different from 0 the following is correct?

\dfrac{a+b}{c}=\dfrac{a}{c}+\dfrac{b}{c}

Then,

\dfrac{41-13i}{25}=\dfrac{41}{25}-\dfrac{13}{25}i

So,

a=\dfrac{41}{25}\\\\b=\dfrac{-13}{25}

Thank you.

A baseball player has 39 hits in 134 times at bat. how many hits must he get in the next 46 times at bat to finish the year with
faust18 [17]

Answer:

He must get 33 hits in his next 46 times at bat to finish the year with a .400 batting average

Step-by-step explanation:

The player has already batted 134 times and will still bat 46 times. So in the end of the year, he is going to have 134 + 46 = 180 at bats.

How many hits does he need to have to hit .400?

This is 40% of 180, which is 0.4*180 = 72.

He has already 39 hits, so in his next 46 at bats, he will need 72 - 39 = 33 hits.
