Answer:

IF the graph shows a various of 2 x the value or 3 x the value we select the most balanced of negative 2x the value and 3 x the value.

If the graph shows just positive x2 or x3 x 4 we select the average. 3x $275000 = $875000 or 2x $275000 =£550000 etc.

Convert the following equation into<br> standard form.
kicyunya [14]

Answer:

7x+9y=45

Step-by-step explanation:

Standard equations always mean that you have to get x and y on one side so that they equal the coefficient.

Do this by adding the fraction that is combined with x to the other side where y is. The equation should now read \frac{7}{9} x + y = 5

Standard form cannot have fractions, so now you must multiply by the denominator (9) on both sides of the equation in order to cancel it out. Don't forget to multiply EACH variable by 9. This leads you to the answer.
