Answer:
-25
Step-by-step explanation: When you multiply to negatives together you get a positive thus being shown in the problem -5 times -1 =5 then you multiply 6 times -5 and whenever you multiply a positive number by a negative you'll always get a negative number so 6 times -5 =-30 then you add 5 and -30 and you get -25. I hope this is right :D
Answer:
d
Step-by-step explanation:
same explanation as before just replace the current values with the previous explanation
Let's solve this by substitution. Note that y is defined: y = 2x - 2. Subst. 2x - 2 for y in the other equation: -6x + 3(2x - 2) = 18.
Then -6x + 6x - 6 = 18. Unfortunately, -6 does not equal 18, so there is no solution. The graphs of these two lines are parallel.
Answer:
I think it’s the second one, 70a+21b sorry if I’m wrong!
Well, since they are different degrees, there aren’t much similarities.
But both can have y-intercepts, x-intercepts, and can be graphed on a 2-dimensional plane. However, other than that, there may not be a lot of similarities.
A standard quadratic function is of the form ()=2++
f
(

)
=

c
and has the shape of a parabola, while a linear function is of the form ()=+

=

and is just a line.
