Answer:
Convert the decimal number to a fraction by placing the decimal number over a power of ten. Since there is
1
number to the right of the decimal point, place the decimal number over
10
1
(
10
)
. Next, add the whole number to the left of the decimal.
4
7
10

Hints on solving trigonometry problems:
If no diagram is given, draw one yourself.
Mark the right angles in the diagram.
Show the sizes of the other angles and the lengths of any lines that are known
Mark the angles or sides you have to calculate.
Consider whether you need to create right triangles by drawing extra lines. For example, divide an isosceles triangle into two congruent right triangles.
Decide whether you will need Pythagorean theorem, sine, cosine or tangent.
Check that your answer is reasonable. The hypotenuse is the longest side in a right triangle.
How to use the tangent ratio to find missing sides or angles?

Answer:
The value of the computer is given by
.
Step-by-step explanation:
A computer sells for $900.
If the price of the computer loses 30% of its value per year, then it is compounded every year.
Now, the price of the computer t years after it is sold will be
........... (1)
Therefore, the value of the computer is given by the above equation (1). (Answer)
<span>y=2(1)+5,,, y=2+5 then y=7 (1,7).....y=2(2)+5,,,y=4+5 then y=9 (2,9) .....y=2(3)+5,,, y=6+5 then y=11 (3,11)........ y=2(4)+5,,,,y=8+5 then y=13 (4,13) when solving for the y you just have to substitute the values of the x given one by one ..... for the ordered pairs -.... ex. in first equation the given value of x is 1..... so we know that is the value of x and by substituting you can find the value of y which turned to be 7 ,,, to write it (1,7) 1 is the x and 7 is the y ((x,y)
