Answer:
To determine which equation has a maximum at y =5, you will need to compare their graphs looking only at the x-values between 0 and 27.
Step-by-step explanation:
We can see by manually counting the squares, that
BC has a length of 2 and AC has a length of 3
using the pythagorean theorem, which is a²+b²=c², we can figure out the length of the missing side, AB.
a, is one side of the triangle
b, is another side
c, is always the hypotenuse, or the slanted side.
so if we fill this in with the appropriate numbers, we can solve for c
(2)² + (3)² = c²
4 + 9 = c²
13 = c²
square root both sides
√13 = √c²
√13 = c
√13 ≈ 3.6056 units
Answer:
(x+4)(x+5)
Step-by-step explanation:
Before we figure out the problem, we must know that the two numbers in the expression must equal the middle number when added and that when multiplied they must equal the last number.
To do this, we list the multiplies of 9 and 20.
9: 1,9,3
20:1,20,2,10,4,5
From there, you go through both lists and follow the given rules stated at the top. When you do that you get, <u><em>(x+4)(x+5)</em></u>.
To check this answer, you can do a various amount of proofs but the most effective one to me is the F.O.I.L. (first, inner, outer, last) and voila.
Yes I hope it helps and sorry if it’s wrong
The equation would equal -9=x
2x-1=3x+8
-2x -2x
——————
-1= 1x+8
-8 -8
——————
-9=x
