Answer:
The number is 
Step-by-step explanation:
Denote the original number by z. The expression "Four less than nine times a number is one hundred twenty-two" can be rewritten in an equation.
Our number is z, then the left hand side of the equation is 9z-4.
The right side of the equation is 122. Then the complete equation is 
. Add 4 in both sides to get 
. Now, divide by 9 in both sides to get 
Answer:
The amplitude is 
Step-by-step explanation:
Let f(x) be a sinusoid function that has the following format:
Then b is the amplitude of the function
h is the vertical displacement of the wave
s is the phase angle
is the period.
In this problem 
Then 
Therefore the amplitude of the function is
The amplitude is a measure of the vertical size of the sinx wave
Answer:
the slope is -2/1
Step-by-step explanation:
(10,-9) and (3,5)
y2-y1/ x2-x1
5-(-9)/3-10
14/-7
<span>8x² - x + x² + 4x - 9x² = 18
3x = 18 | 8x</span>² + x² - 9x² = 0<span>
x = 6 | divide by 3
Answer: x = 6</span>
49 divided by 7 is 7.
