-x + 5y = 4 ⇔ slope 1/5, y-intercept 4/5

5y - x = 15 ⇔ slope: 1/5, y-intercept: 3

2y - 3x = 7 ⇔ slope: 3/2, y-intercept: 7/2

2y = 5x + 7 ⇔ slope: 5/2, y-intercept: 7/2

Explanation

-x + 5y = 4

5y = x + 4

y = (1/5)x + 4/5 slope 1/5, y-intercept 4/5

5y - x = 15

5y = x + 15

y = (1/5)x + 3 slope: 1/5, y-intercept: 3

2y - 3x = 7

2y = 3x + 7

y = (3/2)x + 7/2 slope: 3/2, y-intercept: 7/2

2y = 5x + 7

y = (5/2)x + 7/2 slope: 5/2, y-intercept: 7/2

The 12th term of the arithmetic sequence is 10.5. The 18th term of this sequence is 13.5. Find the common difference and the fir

xxMikexx [17]

Answer:

common difference is 0.5

first term is 5

Step-by-step explanation:

use the formula for the nth term of an ap Tn=a+(n-1)d

T12=10.5

T18=13.5

therefore come up with two equations

T12=a+(12-1)d

10.5=a+11d(1st equation)

T18=a+(18-1)d

13.5=a+17d(2nd equation)

then solve both as a simultaneous equation

a+11d=10.5

a+17d=13.5

-6d/-6=-3/-6

d=0.5

use one of the equations to find the first term

a+11(0.5)=10.5

a+5.5=10.5

a=10.5-5.5

a=5

Identify the segment bisector of XY.

Ganezh [65]

Given the image attached, the segment bisector that divides XY into two and the length of XY are as follows:

Segment bisector of XY = line n
Length of XY = 6

Recall:

A line that divides a segment into two equal parts is referred to as segment bisector.

In the diagram attached below, line n divides XY into XM and MY.

Thus, the segment bisector of XY is: line n.

Find the value of x:

XM = MY (congruent segments)

Substitute

$5x + 8 = 9x + 12$

Collect like terms and solve for x

$5x + 8 = 9x + 12\\5x - 9x = -8 + 12\\\\-4x = 4\\\\x = -1$

XY = XM + MY

$XY = 5x + 8 + 9x + 12$

Plug in the value of x

$XY = 5(-1) + 8 + 9(-1) + 12\\\\XY = -5 + 8 -9 + 12\\\\\mathbf{XY = 6}$

Therefore, given the image attached, the segment bisector that divides XY into two and the length of XY are as follows:

Segment bisector of XY = line n
Length of XY = 6
