Answer:
g(x) = - x-2, therefore g(3) = - 3-2, or in better terms, g(3) = -5
Step-by-step explanation:
Answer:
3. 11 (B)
6. (-2, 18) (D)
8. I see the answer choices now, it would be A.
I don't see any answer options, but anything that goes along the lines of the points form a line, it has a direct relationship, it is linear, etc.
Step-by-step explanation:
3. You are given the expression 6x^2 - 13 and told to evaluate it at x = 2
this yields 6(2)^2 -13 which is 24-13 = 11.
6. You are given the equation y = -9x and 4 choices for ordered pairs. Best way to do this is to plug in the values and see which one works. (But if you want to do this quick you realize that the since you are multiplying one of the values by a -9 this means that the signs of the ordered pair has to be opposite and that only occurs in D (-2, 18) Plug it in and it works.
8. Each time you pay for the meter, it costs $1 or 4 quarters. And you pay per hour. Therefore if the x - axis is time (hours) and the y axis was the number of quarters, you can see that for 1 hour you pay 4 quarters, 2 hours you pay 8 quarters, 3 hours you pay 12 quarters, etc.
You can connect the dots on the graph and you can see that it is linear, you can also verify this by finding the slope between each point and find that the slope (change in y / change in x) is all the same.
Answer for y-2x^2-8x+ 10 is -10
Answer:
, 
, and 
.
Step-by-step explanation:
What is a rational number? By definition, a rational number can be represented as the fraction of two integers.
The goal is to find three fractions in the form 
between 
and 
.
.
At this moment, there doesn't seems to be a number that could fit. The question is asking for three of these numbers. Multiple the numerator and the denominator by a number greater than three (e.g., five) to obtain
.
Since 
and 
can be any integers, let 
.
.
.
Possible values of are 26, 27, and 28. That corresponds to the fractions
, , and .
These are all rational numbers for they are fractions of integers.
