Answer» Solution :Question 1 :- Given equation : 2x + πy = 4 If y = 0 , then => 2x + πy = 4 => 2x + π•0 = 4 => 2x = 4 => X = 4/2 => x = 2 Hence , (2,0) is a solution of the given equation . °°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°° Question 2 :- Given equation : 3bx - y = 9 It is said that , (3,3) is one of the solution of the given equation . Thus , The COORDINATES of the point (3,3) must satisfy the given equation . Now , PUTTING x = 3 , y = 3 in the given equation , We have ; => 3bx - y = 9 => 3b•3 - 3 = 9 => 9b - 3 = 9 => 9b = 9 + 3 => 9b = 12 => b = 12/9 => b = 4/3 (Answer) Hence , Required value of b is 4/3 . °°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°° Question 3 :- Given equation : 2x + 3y = 18 Answer : Infinitely many solutions Reason : • If a system contains only one equation , then it has infinitely many solutions . • A straight line has infinitely many solutions as infinitely many POINTS lies on it . °°°′°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°° Question 4 :- Given equation : 3x - 4y = 12 If x = 0 , then => 3x - 4y = 12 => 3•0 - 4y = 12 => 0 - 4y = 12 => -4y = 12 => y = 12/-4 => y = -3 If y = 0 , then => 3x - 4y = 12 => 3x - 4•0 = 12 => 3x = 12 => x = 12/3 => x = 4 Hence , (0,-3) and (4,0) are two solutions of the given equation . • The equation has infinitely many solutions as Infinitely many points lies on it . • A system containing only one equation has infinitely many solutions . |

If thesumZerosofthequadratic polynomial kx² + 2x +3kisequal toto their product findthe valueof k |
|
Answer» GIVEN :– • A quadratic EQUATION kx² + 2X +3k = 0 have two roots α and β . • Sum of roots (α + β) = Product of roots (αβ) . TO FIND :– • Value of 'k' = ? SOLUTION :– ▪︎ We know that – => Sum of roots = α + β = -( coffieciant of x)/(coffieciant of x²) => α + β = - (2/k) ——————eq.(1) ▪︎ And – => Product of roots = αβ = (constant term)/(coffieciant of x²) => αβ = (3k)/(k) => αβ = 3 ——————eq.(2) ▪︎ Now According to the eq.(1) & eq.(2) – => -(2/k) = 3 => -2 = 3k => k = - (2/3) ● Hence , The value of k is -(⅔) . |

Answer» Answer: ASK Find an Online Tutor Now PRECALCULUS WORD PROBLEM EQUATIONS SYSTEM OF EQUATIONS SYSTEMS OF EQUATIONS BY ELIMINATION SYSTEMS WORD PROBLEM HELP WRITING AN EQUATION Lobby D. asked • 12/01/14 System of Equations word problem I can't figure out!!!! A basketball player scored 40 points in a game. The number of three-point field goals the player made was 22 less than three TIMES the number of free throws (each worth 1 point). Twice the number of two point field goals the player made was 11 more than the number of three point field goals made. Find the number of free-throws, two point field goals, and three point field goals that the player made in the game. Once I have the equations I understand how to do the problem, but I am obviously doing something wrong because each time I WRITE out the equations I end up getting fractions. Follow4 Add comment More 2 Answers By Expert Tutors By: Bill P. answered • 12/19/14 TUTOR New to Wyzant A math tutor that is both knowledgeable and patient in secondary math. SEE TUTORS LIKE THIS If you let x represent the number of free throws (worth 1 point each) let y represent the number of two-point field goals (worth 2 points each) let z represent the number of three-point shots made (worth 3 points each)
Then the correct system of linear equations is as follows:
x + 2Y + 3z = 40 (The total number of points scored is 40.) z = 3x - 22 (The number of 3-pointers was 22 less than 3 times the number of free throws.) 2y = z + 11 (Twice the number of 2-point shots made was 11 more than the number of 3-pointers.)
The solution is as follows:
This basketball player scored 9 points via free throws (9 at 1 point each), 16 points via 8 two-point shots made, and 15 points via 5 three-point shots made.

Answer» ANSWER Mode is the value which OCCURS most often in the data set of VALUES. Given data values are 2,4,6,7,5,6,10,6,7,2k+1,9,7,13 In the above data set, values 6,7 have occured more times i.e., 3 times But given that mode is 7. So, should OCCUR more times than 6. Hence the variable 2k+1 must be 7 ⟹2k+1=7 ⟹2k=6⟹k= 2 6
