Elimination 2x - 5y = 8 x - 3y = -1

1 answer:

8 0

X=29 and y=10

You would isolate one of the variables and then plug the expression into the other equation to find the value of one variable. Then you would plug this value into the other equation to determine the value of the remaining variable.

Enter the value that is missing

masha68 [24]

I think it’s 15.75. Because: 2•1.05=2.10. 5•1.05= 5.25. 20•1.05= 21.00. So, 15•1.05= 15.75.

A point Q on a segment with endpoints A (2, −1) and C (4, 2) partitions the segment in a 4:1 ratio. Find Q.

Annette [7]

The point Q on a line segment with end points(2,1) and (4,2) is Q(12/5, -2/5)

<h3>What is a line segment?</h3>

A line segment is a straight line that passes through two given points.

The end points of the line determine how long or short a given line segment would be.

Analysis:

point Q(x, y )

x = $\frac{MX1 + NX2}{M+N}$

y = $\frac{MY1 + MY2}{M+N}$

where M :N = 4:1

x1 = 2, x2 = 4, y1 = -1, y2 = 2

x = $\frac{4(2) +1(4)}{4+1}$ = 12/5

y = $\frac{4(-1) + 1(2)}{4+1}$ = -2/5

In conclusion, the point Q is (12/5, -2/5).
