Answer:
No.
Step-by-step explanation:
Sam is incorrect because if you look at the original problem, you'll see that he has missed the negative sign!
90 / 9 does equal 10, but 90 / -9 equals -10.
The only way to get a positive answer is if both the divisor and dividend are positive or if they are both negative.
Thus, the correct answer should be -10.
The simplest form is 4y+6?
you distribute the 4 to everything in the parentheses and then combine like terms so you would combine the 8 and -2
This is simple. Coordinate form is (x,y) so you would just plug in your values.
2(5)-(1)=11
10-1 does not equal 11, so no it is not a solution.
Answer:
The second equation is correct.
y=2.25x + 4
Step-by-step explanation:
We can systematically eliminate the others.
For equation 3 and 4, 6.5*2 and 12*x is already bigger than 8 of the first set of numbers.
For equation 1, 2*x+8.5 is also bigger than 8 from the first set.
Plugging in the values to equation 2, we always get the correct cost.
