Answer:

Step-by-step explanation:
Consider the equation

Substitute

into the equation:

This is quadratic equation, where

Hence,

Now, use the substitution again:
1. When
then

2. When
then

This equation has no solutions, because the range of
is
and 3>1.
Answer:
1/18
Step-by-step explanation:
Assuming the die are regular 1,2,3,4,5,6
P(2) = number of 2's/ total numbers on die
= 1/6
Roll again
Assuming the die are regular 1,2,3,4,5,6
P (numbers greater than 4) = {5,6}/total numbers on die
=2/6 = 1/3
P (2, then number greater than 4) = 1/6 * 1/3 = 1/18
Answer:
307°
Step-by-step explanation:
The sum of all the angles of a hexagon is equal to 900°.
So,
112+x+120+100+128+133 = 900
593+x = 900
x = 900-593
x = 307°
So, the value of x is equal to 307°.
Answer: 
Step-by-step explanation:
Creating identical expressions involves changing quantities in a way that preserves the end values specified in the equation.
For instance, if Lei sold 4 carnations:

In the second equation listed, the expression (8 + 0.25c) was multiplied by 4, then by 0.25, for a total multiplicand of 1.
You can make a third equation through the same method. I'll multiply (8 + 0.25c) by 2, and then multiply that expression by 0.5 to keep the multiplicand unchanged:

If Lei sold 4 carnations:
0.5 * (16 + 2) = 9
This equation represents the same quantities as the other equations.
The range is all of the y values.
The domain of all quadratics is all real numbers, but the range of y=x^2 is y≥0. This is because quadratic functions graph to form a parabola, which, when the a value is positive, opens upward. The lowest y value when graphed is 0 and all other values are more than that.
