Q.1=DRAW THE GRAPH OF x+y+1=0 and 3x +2y-12=0.Determine the coordinates of the vertices of the triangle formed by these lines and x axis .Calculate the area bounded by these lines and x axis.
Two lines are given to be parallel. The equation of one of the lines is 4x + 3y = 14. Find the equation of the second line.
how to solve (a-b)x + (a+b)y = (a2-2ab-b2) , (a+b) (x+y)=a2+b2. by cross multiplication method
The pair of equations ax + 2y = 7 and 3x + by = 16 represent parallel lines if
a. a=b b. 3a = 2b c. 2a = 3b d. ab = 6
a plane left 30 minutes later than the scheduled time and inorder to reach the desination, 1500km away in time. It has to increase the speed by 250km/h from the usual seed. Find the usual speed?
solve for x and y
x / a + y / b = 2 ; ax - by = a2 - b2
A boat goes 30 Km upstream and 44 KM downstream in 10 hours.In 13 hours, it can go 40 KM upstream and 55 KM down- stream. Determine the speed and that pf the boat in still water....????
kindly explain this question....
if √ax-√by=b-a and √bx-√ay=0 then value of x,y is
2 women and 5 men can together finish an embroidery work in 4 days, while 3 women and 6 men can finish in 3 days. find the time taken by 1 woman alone to finish the work, and also that taken by 1 man alone
The pair of equations y=0 and y= -7 will have :
(a) One solution
(b) Two solutions
(c) Infinitely Many solutions
(d) No Solution
Justify your answer please!
A man travels 600km partly by train and partly by car. If he covers 400km by train and the rest by car, it takes him 6 hours and 30 minutes. But if he travels 200 km by train and rest by car, he takes half an hour longer. Fine the speed of the train and that of the car
Find the value of k for 2x + 5y=0, kx+10y=0 has non zero solution. PLz fast tommorow is my fa
Students of a class are made to stand in rows. If one student is extra in a row, there would be 2 rows
631x + 279y = 910
279x + 631y = 910
Points A and B are 90 km apart from each other on a highway. A car starts from A and another from B at the same time. If they go in the same direction they meet in 9 hours and if they go in opposite directions they meet in 9/7 hours. Find their sppeds.
How many solutions does the pair of equations y=0 and y = -x has? explain
Places A and B are 100 km apart on a highway. One car starts from A and another
for what value of K will the following pair of linear equation have no solution
covered a certain distance at a uniform speed. If the train would
have been 10 km/h faster, it would have taken 2 hours less than the
scheduled time. And if the train were slower by 10 km/h; it would
have taken 3 hours more than the scheduled time. Find the distance
covered by the train.
A train covered a certain distance at a uniform speed. If the train would have been 6km/hr. faster, it would have taken 4 hours less than the scheduled time. And if the train were slower by 6km/hr. it would have taken 6 hours more than the scheduled time. Find the length of the journey.
A sailor goes 8 km downstream in 40 minutes and returns in 1 hour.Determine the speed of the sailor in still water and the speed of the current?
