The Multiplicative Identity Property. This means that you can multiply 1 to any number... and it keeps its identity! The number stays the same!
1,09 kl =1,090 l (liters)
You will have $1095 when you take your money out after ten years.
Using substitution:In the first equation, look to solve for x
{x + 3 y = 8
{4 x - y = 6
Subtract 3 y from both sides:
{x = 8 - 3 y
{4 x - y = 6
Substitute x = 8 - 3 y into the second equation:
{x = 8 - 3 y
{4 (8 - 3 y) - y = 6
4 (8 - 3 y) - y = (32 - 12 y) - y = 32 - 13 y:
{x = 8 - 3 y
{32 - 13 y = 6
In the second equation, look to solve for y:
{x = 8 - 3 y
{32 - 13 y = 6
Subtract 32 from both sides:
{x = 8 - 3 y
{-13 y = -26
Divide both sides by -13:
{x = 8 - 3 y
{y = 2
Substitute y = 2 into the first equation:
Answer: {x = 2
{y = 2
Answer:
48 -52 and 64 - 66
Step-by-step explanation:
sence it dosent give exact numbers on the graph ur going to have to estimate then to find when it increases look for an interval were it goes up reading from left to right and for decreasing look for an interval that is going down reading the graph left to right
