Solve the equation |2x+6|=10 a. (-8,2) b.(8.2) c. (8,-2) d. (-8,-2)

(2x+6)=10,2x=10-6;2x=4:x=4/2:x=2.so pls me no understnd d options ooooo.pls more light on dis mathemtical expression

Joshua15: (2x+6)=10,2x=10-6;2x=4:x=4/2:x=2.so pls me no understnd d options ooooo.pls more light on dis mathemtical expression

The sign| | means either -ve or +ve +-(2x+4)=10; forming two equation, one with + and other with -.

Answer is AAAAAAAA

B

Oh! I tot it was just d sign in d bracket dat wé're to change! Thanks

Answer
2x+6=10
2x=4
x=2

2x+6=-10
2x=-16
x=-8

answer (-8,2)

That question is under inequality and| | is called a modulus sign. Question 50. The solution set of the inequality |2x+6|<10 is a) (-3,2) b) (-5,2) c) (-8,2) d) (-3,

Solution-|2x+6|<10. Rewrite the inequality without the modulus sign:-10<2x+6<10 take away 6 from all sides:-16<2x<4: divide all sides by 2:-8<x<2 (i.e x lies between -8 and 2) thus the answer is C. Take it to any part of the world. Dats d answer.

Solve the following simultaenous equation x+y=10, x2+y2=58.

donfemox: Solve the following simultaenous equation x+y=10, x2+y2=58.

Substitution method is the best in dis case, x=10-y and put into eqn 2, (10-y)^2 + y^2=58; (100-10y-10y+y^2) +y^2=58; 100-20y+2y2=58; 2y2-20y+42=0; divide by 2, y2-10y+21=0 factorise (y-7)(y-3)=0;y=7or3, then x=10-y when y=7 , x=3 when y=3, x=7, (x,y)=(3,7)or(7,3) . success. @ all, learn 2 solve equations wella and quadratic equations-all maths questions lead 2 equations solving and learn also word problems, probability.

Ur solution was on point mr matt. Dats d answer. Pls more questions o

Phil i gat ur no. Gona buzz you. Success is ours in jesus name.

A man is x years old while his son is y years old. The sum of their ages is twice the difference of their ages. If the product of their ages is 675, find the age of the man. a) 40 years b) 42 years c) 55 years d) 45 years

X+y= 2(x-y)
X+y= 2x-2y
x-2x=-2y-y
-x= -3y
x = 3y
If the product of their ages is 675
X x Y = 675
Replace x with 3y
Y(3y) =675
3y^2 =675
Divide both sides by 3
Y^2 = 675/3
Y^2 = 225
Y= square root of 225

Y= 15......which is the son's age

Then, X= 3y
X= 3(15)
X= 45

Therefore, the man's age is 45

45X15 = 675

Am i right?

U re (over) right. Good guys re here or very good bad guys. Keep it up. It can't come in better package than this. Gr8 job.

Hey guys here...i'm gonna veer off-point... i have a friend who wants to enter unilag but whenever he tries to register online, they request for his Jamb reg number and Phone number but when he feeds in both, a return page says the registration number doesnt exist but he has unilag as first choice, got 218 in jamb and applied for physics...someone pls address this issue..thanks in advance...and has the registrataion date closed?

Maths Question 100 in the revision questions is my next agbara/power as we used 2 call tough questions in our secondary days with correct guys in lagos then. About two digit number I dey wait ur solution.

Three times the tens digit of a two digit number is 2 greater than the unit digit. When the digits are interchanged the new number is 36 more than the original number. What is the original number? a) 35 b) 37 c) 15 d) 28

my score in UTME is 258, and i have divided it with 8, which give me 33ponit, and i am applying for Sociology, please how many point am i to meet up in my post UTME exam. and my exam is on 13th July, 2012. wish me and my fellow best of luck ooooooooooo
