Answer: D
Step by Step: Even though the y value repeats, to be considered not a function is when the X value repeats
Answer:
b = 
Step-by-step explanation:
Using the rule of logarithms
log 
⇔ nlogx
Given
190 = 
( take the natural log ln of both sides )
ln190 = ln = bln200 ( divide both sides by ln200 )
= b
Two linear equations can have no solutions, exactly one solution or infinitely many solutions. There will be no solution if the lines are parallel on a graph. There will be exactly one solution if the lines intersect each other on a single point. And finally, there will be infinite solutions if the lines overlap each other perfectly.
A single line however has infinite ordered pair solutions as the line travels infinitely in both directions on the coordinate plane. For example, using the equation y=3x, for any real value of x, we will get a real value for y.
Linear inequalities with two variables have infinitely many solutions. We can use the inequality y>3x as an example. For any real value of x, we will get a real value for y.
I hope this helps!
I think the easiest way to answer all of these is to just go ahead and find the equation of the line first.
I'm pretty sure that by the time you reach this problem, you've learned to find
the equation of a line that passes through two given points. You have two points: (2, 100) and (5, 205). The equation of the line through them is [ y = 35x + 30 ].
6). The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30. (Also the y-intercept.)
7). The cost per month is $35. (The slope of the line.)
8). We already did that, up above. [ y = 35x + 30 ].
9). 'x' in the equation is the number of months.
There are 12 months in one year.
y = 35(12) + 30 = $450
Step-by-step explanation:
let eqn be y = mx + b.
m = (5 - (-11))/(0 - 4) = -4
sub (0, 5):
5 = -4(0) + b
b = 5
therefore, eqn is y = -4x + 5
