The first term on an A.P is p ans its common difference is q. Find its 10th term.

maria [59]

Answer:

p + 9q.

Step-by-step explanation:

The explicit formula for the nth term of an A. P is

an = a1 + d(n - 1) where a1 = the first term and d = the common difference.

So the 10th term when a1 = p and d = q is:

a10 = p + q(10 - 1)

= p + 9q.

For which values of a the system 3−7x < 3x−7 ,1+2x < a+x has no solutions?

erica [24]

Answer:

a= -infinity to 3

Step-by-step explanation:

Given

$3 - 7x < 3x - 7$

$1+2x < a+x$

Required

Determine the value of a such that the inequality has no solution

Considering the first inequality (Solve for x):

$3 - 7x < 3x - 7$

Collect Like Terms

$3 + 7 < 3x + 7x$

$10 < 10x$

Divide both sides by 10

$1 < x$

Reorder

$x > 1$

This means that the least value of x is 2;

Substitute $x=2$ in the second equation

$1+2x < a+x$

$1 + 2(2) < a + 2$

$1 + 4 < a + 2$

$5 < a + 2$

Collect Like Terms

$5 - 2 < a$

$3 < a$

Reorder

$a > 3$

This means that the least value of a is 4

Hence;

The values of a for which the system has no solution is -infinity to 3

2х - 4 = 3y 5y - x =5

yawa3891 [41]

Answer:

x=5

Step-by-step explanation:

Lets first solve for y on both sides:

$2x-4=3y\\\frac{2x-4}{3}=y\\ y=\frac{2x-4}{3}$

$5y-x=5\\5y=5+x\\y=\frac{5+x}{5}$

Set the two equations equal to each other and solve for x:

$\frac{2x-4}{3}=\frac{5+x}{5}$

Multiple both sides by 3:

$2x-4=\frac{3(5+x)}{5}$

Multiply both sides by 5:

$5(2x-4)=3(5+x)$

Apply distributive property to both sides:

$10x-20=15+3x$

Add 20 to both sides:

$10x=35+3x$

Subtract 3x from both sides:

$7x=35$

Divide both sides by 7:
$x=5$
