-42/8=-1 times 42/8=-1 times 21/4=--1 times 5 and 1/4=-5 and 1/4
It is reflection in x axis and then vertical shift up by 4 units and horizontal shift to the left by 2 units
Explanation:
It is reflection in x axis and then vertical shift up by 4 units and horizontal shift to the left by 2 units
Look at the three graphs y=|x| in pink. y=-|x| in white and y=4-|x+2| in red
A pair of fractions that have the same product is 1/2 and 2/4 because they are both half.
Hope I helped! Also I hoped this is what you meant by the finding a pair of fractions with same products. :D
C = children
a = adults
12c + 15a = 33456 (price)
c + a = 2450 (people)
c = 2450 - a (rewrite^)
12(2450 - a) + 15a = 33456 (substitute into the price equation)
29400 - 12a + 15a = 33456
3a = 4056
<u>a = 1352
</u>c = 2450 - (1352)
<u>c = 1098</u>
1098 children
1352 adults
If the sub is 450 below sea level, then the number would be -450. Also, if the sub is ascending, it is going up. You would have to do -450+275 to get -175.
