A polynomial expression can only be categorized into a function if and only if a single input can only have one and only output. This means that there should be no more than one dissimilar values of y for the same value of x.
Evaluating the givens above, it can be observed that there are two -1's as an x-coordinate and it has two outputs, 0 and 1. Thus, we can remove either (-1,0) or (-1,1) for the relationship to become a function.
Answer:
21 gallons.
Step-by-step explanation:
Let the number of gallons that the tank holds be x gallons.
1/2x + 7 = 5/6 x
5/6x - 1/2x = 7
5/6 x - 3/6 x = 7
1/3 x = 7
x = 21.
The perimeter is 20 feet, half the perimeter Would be 10 feet.
Need 2 numbers when added together equal 10 and when multiplied together equal the area of 21.
3 and 7 The pond is 3 feet by 7 feet.
Answer:
q = 80 degrees
r = 70 degrees
s = 10 degrees
t = 70 degrees
u = 40 degrees
v = 60 degrees
Step-by-step explanation:
starting with the fact that all angles in any triangle always sum up to 180 degrees :
q = 180 - 60 - 40 = 80 degrees
r = 180 - (60+10) - 40 = 180 - 70 - 40 = 70 degrees
the triangle 40-60-q and v-u-blank are similar triangles. your can say the smaller triangle is just a projection of the large triangle through the focal point at angle q.
that means the angles must be equal.
v = 60 degrees
u = 40 degrees
similar for 10-r-blank and t-s-blank.
s = 10 degrees
t = 70 degrees
