Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
Say y = pi*x/4
we know
sin(y) = 0 at y=0,pi,2piso set up three equationpi x/4 = 0 or pi or 2pi and solve for x
3x +4 is 7x and 4x- 1 is 3x because yhat how you solve that
For the first one, remember that the parent function is y = x² for a parabola. The modifications made are the subtraction of five from the square of x, and the square of x is also being multiplied by two.
For the second one, look at the roots (Where the graph crosses the x - axis). From them, we can create a function with the following steps:
1.) Put the two roots into monomials:
(x - 1)(x - 3)
2.) Multiply them together with FOIL (First, Outside, Inside, Last):
x² - 3x - x + 3
x² - 4x + 3
3.) You have your answer!
x² - 4x + 3

Answer:
math
Step-by-step explanation:
1. First we divide 3/4m by 3/4 and -12 by 3/4. When -12 is divided by 3/4, the solution is m>-9, which is answer choice number 3.
2. Again, all you have to do is divide both sides by 1.2. ((4 1/2) / 1.2 = 3.75) which is answer 1.
3.
1. Since we have to solve this inequality, we need to divide both sides by -4. (8.4 / -4 = -2.1). Because we divided by a negative, we need to flip the sign, making the inequality x<-2.1 and <------------0
2. Same as above, except we don't flip the sign. ((3/4) / (3/5) = 1 1/4). The solution is z>1 1/4 and 0------------>.
3. Again, the same. (-16 / -4 = 4) Since we divided by a negative, we flip the sign. The solution is 4≤p and 0-----------> with closed circle.
