Remember you can do anything to an equation as long as you do it to both sides

15-1t+8t=-13
15+7t=-13
minus 15 both sides
7t=-28
divide both sides by 7
t=-4

4a+11-1a=2
3a+11=2
minus 11 both sides
3a=-9
divide by 3 both sides
a=-3

15-t + 8t = -13
15 + 7t = -13
7t = -13-15
7t = -28
t = -4

4a + 11-a = 2
3a = 2-11
3a = -9
a = -3

Find the 4th term in the sequence with the following definition:

eimsori [14]

The 4th term in the sequence is -37

<h3>Recursive function</h3>

Given the following recursive function and first term as show below

a1 = -2

an = 2an-1 - 3

For the second term

a2. = 2a1 - 3

a2 = 2(-2) - 3

a2 = -7

For the third term

a3 = 2a2 - 3

a3 = 2(-7) - 3

a3 = -17

a4 = 2a3 - 3

a4 = 2(-17) - 3

a4 = -37

Hence the 4th term in the sequence is -37

At 0°C, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in lit

liubo4ka [24]

At $T=0^{\circ}C$ , the volume of the gas is V=22 L.

At temperature $T=1C$ , the volume of the gas is (22+225) L.

This means that if we increase the temperature by $k$ degrees:
$T=k^{\circ}C$
the volume of the gas is
$V=22 + 225 k [L]$ (1)

Since T=k, we can rewrite eq.(1) as
$V= 22 + 225 T [L]$
which gives the expression for the volume of the gas in liters, as a function of the temperature T in Celsius.
