168/8 = x
x=21
Thus your equation is 21x where x equals amount of hours worked and 21 equals the amount he makes per hour
Answer:
{121,144,169} X intersecting Y means common number between x and y set
Answer:
Step-by-step explanation:
From the given information:
(a)
Since growth quantity is not continuous
For t = 10
(b)
Here, for a continuous growth rate, the growth quantity can be computed in terms of initial quantity and the growth rate.
i.e.
At t = 10 for a continuous growth rate;
The answer is obtuse
a = 4
b = 28
c = 31
If a² + b² > c² - the angle is acute
If a² + b² < c² - the angle is obtuse
If a² + b² = c² - the angle is right
a² + b² = 4² + 28² = 16 + 784 = 800
c² = 31² = 961
800 < 900
a² + b² < c²
Therefore, the angle is obtuse
Answer:
x= -7
Step by Step Explanation:
We can write them both like functions like this
A= 5x- 4
B= 3x+ 8
The output of A will be three times the output of B
A=3b
We replace with the functions
5x-4= 3
We solve for x
5x= -4= 9x + 24
5x- 9x= 24 + 4
-4x= 28
x= 28 - 4
x= -7
The output that makes the out put of A 3 times the output of B is -7
