To find the x-intercept, we can put 0 into y, as any x-intercept would have a y-coordinate at 0.
y=0
y = −12x + 3
0 = -12x + 3
12x = 3
x = 3/12
x = 0.25 or 1/4
Therefore, the x-intercept=0.25 or 1/4.
Hope it helps!
Simple interest is where 3% of the original value is added on each year
goal number = $102
original number = $680
3% of $680 can be found by getting 1% and multiplying by 3
100% = original number = $680
100% / 100 = 1% so $680 / 100 = $6.80 = 1%
3% = $6.80 * 3 = $20.40
so each year the money rises by $20.40
to find out how many years it would take to get to $102:
$102 / $20.40 = 5 years
Answer:
You can tell if two fractions are proportional by using cross multiplication. Only equivalent fractions are proportional. To do this, multiply the denominator, the bottom number in the fraction, of the first fraction with the numerator, the top number in the fraction.
Step-by-step explanation:
Multiplying fractions, unlike adding them, does not require you to find a common denominator. Simply multiply the numerator and denominator and simplify if you have to. In this case, it's .
-->
A negative multiplied by a positive is still negative, so this becomes .
