Answer:
false is the correct answer right
Answer:
2t
Step-by-step explanation:
The expressions are not the same because different terms are negative. We can visualize the difference by rewriting the expressions as 13t + (-2t) and (-13t) + 2t. In the first expression, 13t-2t, the 2t is negative because it is being subtracted, and subtracting a number is the same as adding a negative.
Answer:
B. 3
It says the answer is too short so im just typing random stuff
Part A
The scatterplot is shown the attachment.
Part B
Using a linear regression equation that models Patrick's referrals has a positive slope.
This means that, there is a positive relation between time(number of days),x and the number of personal recommendations, y.
In other words, as the number of days increases, the number of personal recommendations also increases.
Question 2.
The given functions are:
![y=x^2+3x-5](https://tex.z-dn.net/?f=y%3Dx%5E2%2B3x-5)
![y=4x+1](https://tex.z-dn.net/?f=y%3D4x%2B1)
To find the point where the graphs of these functions intersect,we solve the two equations simultaneously.
We equate the two equations to get:
![x^2+3x-5=4x+1](https://tex.z-dn.net/?f=x%5E2%2B3x-5%3D4x%2B1)
![x^2+3x-4x-5-1=0](https://tex.z-dn.net/?f=x%5E2%2B3x-4x-5-1%3D0)
![x^2-x-6=0](https://tex.z-dn.net/?f=x%5E2-x-6%3D0)
Factor to obtain:
![(x-3)(x+2)=0](https://tex.z-dn.net/?f=%28x-3%29%28x%2B2%29%3D0)
x=3 and x=-2
We put x=-2, into
to get;
![y=4(-2)+1=-7](https://tex.z-dn.net/?f=y%3D4%28-2%29%2B1%3D-7)
when x=3 ![y=4(3)+1=13](https://tex.z-dn.net/?f=y%3D4%283%29%2B1%3D13)
Therefore the graphs intersect at (-2,-7) and(3,13).
Yes, solution is correct.
Answer:
Yes.
Step-by-step explanation:
10% is 0.10 in decimal form. Therefore, once he pays the $17.80 setup fee and then 0.20f (or $0.20 per flyer), then we would multiply by 10% (Or 0.10).
In conclusion:
Yes. 0.10( 17.50 + 0.20f ) does represent the total cost of the print job.
