Answer:
30 degrees
Step-by-step explanation:
<ACB is a central angle while <ADB is an inscribed angle.
Central angles are twice the size of inscribed angles.
Therefore, <ADB*2 = <ACB . 15*2=30
The answer is D. -(4x-3)(5x-2)
Answer:
Please check solution for answer
Step-by-step explanation:
The general equation of for the slope of a line is
y = mx + c
where m is slope and c is the y-intercept
a). Yes it is in the slope-intercept form
b) The slope would represent the amount of money in dollars per week that is in the wallet
c) The y-intercept would be 125 and it is the amount of money present in the wallet before today
d) The slope would have a unit of dollars per week
Given:
![-2(x+2)>4-x](https://tex.z-dn.net/?f=%20-2%28x%2B2%29%3E4-x%20)
This is an inequality. Normally when solving inequalities, we treat the inequality like an equal sign. Let's begin to solve. First, let's distribute on the left side. Multiply -2 by everything in the parenthesis:
![-2x-4>4-x](https://tex.z-dn.net/?f=%20-2x-4%3E4-x%20)
Now, let's get the x on the left side of the inequality. It doesn't have to be on the left, but it is good practice when graphing inequalities. Add x to both sides. This will cancel the -x on the right:
![-x-4>4](https://tex.z-dn.net/?f=%20-x-4%3E4%20)
Now, we need to get x all by itself. Let's add 4 to both sides which will cancel the -4 on the right side. We are now left with:
![-x>8](https://tex.z-dn.net/?f=%20-x%3E8%20)
Now, since x cannot be negative, we need to divide both sides by -1. We are then left with:
![x](https://tex.z-dn.net/?f=%20x%3C-8%20)
NOTE: When dividing by a negative (or multiply by a negative fraction) to solve for x, you must FLIP the inequality at the end. This is why it is:
![x](https://tex.z-dn.net/?f=%20x%3C-8%20)
