Answer:
yes
Step-by-step explanation:
they are all equivalent because they all equal 0.9
9/10 = 90/100 = 0.9
all percentages can be converted to fraction by putting them over a hundred
90% = 90/100 = 0.9
0.9 obviously = 0.9
Rather than try to select the correct answer without doing work, I'd rather do the work first and the matching later.
Given y = 4 - x, or y = 4 - 1x,
1) the y-intercept is (0,4).
2) this being a linear function, it has neither maximum nor minimum.
3) the x-intercept is found by letting y = 0 and solving for x: 0 = 4 - x; x - 4. The x-intercept is (4,0).
Which of the given statements is true?
the vertical line test is a graphical way to determine whether or not the graph is a function of x
if you can draw a vertical line on a graph and cross the graph at least 2 times, the graph is not a function
a function will have 1 y value for every x value, therefore, if we can draw a vertical line (x=c, a constant) that intersects the curve at more than 1 point, then that point where it intersects at more than 1 point is where 1 value of x coresponds to more than 1 value of y and is therefore not a function
Answer:
$25 a lamp
Step-by-step explanation:
First divide $10,000 by 500 lamps to find how much one of them cost
That is $20 a lamp so then multiply .25 *20 or 1/4 *20
you get 5 than add 20 +5=25
