Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are: and .
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions and .
We say they are proportional if .
Or, if then we can say the fractions are proportional.
Here the fractions are: and .
LHS: 5 X 10 = 50.
RHS: 8 X 8 = 64.
Clearly they are not equal. So, we can say these two fractions are not proportional.
Assuming that an exponentiation sign is missing, all you need to know is that rational exponents work like this:
So, you have
And similarly,
Construct the line using the two points:
slope: m = (-4 - 2) / (4 + 3) = -6/7;
then, y = mx + b => 2 = (-6/7)(-3) + b => 14/7 - 18/7 = b => b = -4/7.
And your y-intersect is -4/7.
Joan received $17 and 94 cents ($17.94)
$14.20 + $7.86= $22.06 (her total)
$20+$20= $40 (how much she paid with)
$40- $22.06= $17.94
