Answer:
The base is 11 cm.
Step-by-step explanation:
The formula for the area of a triangle is 
. If we plug in what we know to this equation, we are left with 
, which we now need to simplify.
First, we combine like terms.
Then, we can eliminate the 
and 
on the right side of the equation, since they cancel each other out.
Finally, we take the square root of both sides of the equation and find our answer:
There would be 5184 ways in which each subject books can be selected.
<u>Explanation:</u>
Number of geography books = 5
Number of chemistry books = 4
Number of Science books = 7
Different ways of selecting geography books = 5!
= 5 X 4 X 3 X 2 X 1
= 120
Different ways of selecting chemistry books = 4!
= 4 X 3 X 2 X 1
= 24
Different ways of selecting Science books = 7!
= 7 X 6 X 5 X 4 X 3 X 2 X 1
= 5040
Total different possible ways they can select them = 120 + 24 + 5040
= 5184
X=2
Reason why is because 1+1 is 2 and X is what your product is
Answer:
<h2>C) (negative 1, one-half), (0, 1), (1, 2), (2, 4)</h2>
Step-by-step explanation:
The set C could be generated by an exponential function. The main reason is that exponential functions hava a restricted range, it can't have negative numbers or the number zero, because power can only be equal or greater than 1.
Additionally, for all exponentials, a null exponent gives 1 as an answer, so point (0, 1) is always present in an exponential function.
Therefore, the right answer is C.
C. (4,-7)
y=2x-15
-7=2(4)-15
4x+3y=-5
4(4)+3(-21)=-5
