Answer:
One proportion
Step-by-step explanation:
A proportion refers to a statement that two different ratios are equal. There are two ways It can be written: since two equal fractions a/b = c/d; or using a colon, a:b = c:d. in view of the fact that the cross products are of both equal to one hundred, we are aware that these ratios are equal and that this is a true proportion.
Answer:
y =
x + 4
Step-by-step explanation:
Use the slope formula and slope-intercept form
y=mx+b to find the equation.
2/5 in decimal form would be 0.4
So if you want it to be 9 less than your number (x) then you would subtract nine.
So it would be:
x - 9.
So if your "number" is 12 then you would substitute x for 12 and it would be 12-9. The answer is 3. So 3 is 9 less than a number (12).
