Answer:
1) 4x² + 3x
Step-by-step explanation:
Add/Combine like terms:
2x² - 6x² = -4x²
6x - (+3x) = 3x
5 - (+5) = 0
Simplify: -4x² + 3x
They both earn the same salary. Call it ' S '.
After Todd spent 716, he had (S - 716) left.
After Zack spent 128, he had (S - 128) left.
The question says that Zack has 4 times as much as Todd has, so
(S - 128) = 4 times (S - 716)
Eliminate parentheses on the right side:
S - 128 = 4S - 2,864
Subtract ' S ' from each side:
-128 = 3S - 2,864
Add 2,864 to each side:
2,736 = 3S
Divide each side by 3 :
912 = S
==========================
Check:
After Todd spends 716, he has (912 - 716) = 196 left.
After Zack spends 128, he has (912 - 128) = 784 left.
784/196 = exactly 4 times.
yay !
2/3 divided by (-1 and 1/4)
= 2/3 divided by -3/4
= 2/3 * 4/-3
= 8/-9.
= -8/9
The exact values of the trigonometric identities cos, csc and tan as required in the task content are; -√41/5, -√41/4 and 4/5 respectively.
<h3>What are the exact values of cos, csc and tan as required in the task content?</h3>
It follows from above that the terminal side of the angle theta as described is on the point with coordinates (-5, -4).
Hence, the points spans 5 units leftwards and r units downwards on x and y axis respectively.
Hence, the length of the line that describes the angle by Pythagoras theorem is;
h = √((-4)² + (-5)²)
h = √41.
Hence, it follows from trigonometric identities that;
Cos (theta) = -5/√41.
Csc (theta) = -√41/4
Tan (theta) = 4/5
