We use an exponent law here.
Since 1/xⁿ = x⁻ⁿ for positive number <em>a</em> and real number <em>n</em>, it follows that
1 / 9⁴ = 9⁻⁴
Answer:
Draw a graph that joins the points (100, 155) and (200, 245) and has a slope = 0.9
Step-by-step explanation:
x variable represents total megabytes of data used
y variable represents total monthly charges
The company charges $155 (y) for 100 megabytes (x) means that the point (100, 155) belongs to the equation.
The company charges $245 (y) for 200 megabytes (x) means that the point (200, 245) belongs to the equation.
With these two points, the slope is computed as follows:
(245 - 155)/(200 - 100) = 0.9
Hello, thanks for writing in.
First, we times the two bases (5 x 3)(3)
The reason we set this up is because when finding the volume you need to times the two bases THEN the height.
5 x 3 = 15
15 x 3 = 45
Therefore, 35 is your volume.
Let's solve your system by substitution.
y=2x+1;y=4x−1
Step: Solve y=2x+1for y:
y=2x+1
Step: Substitute2x+1foryiny=4x−1:
y=4x−1
2x+1=4x−1
2x+1+−4x=4x−1+−4x(Add -4x to both sides)
−2x+1=−1
−2x+1+−1=−1+−1(Add -1 to both sides)
−2x=−2
−2x
−2
=
−2
−2
(Divide both sides by -2)
x=1
Step: Substitute1forxiny=2x+1:
y=2x+1
y=(2)(1)+1
y=3(Simplify both sides of the equation)
Answer:
x=1 and y=3
Answer:
15/min
Step-by-step explanation:
total no. after 9 min is 144
at 0 min is 9
increase = 135
rate= 135/9
