Yes, so here’s where you should start. the question mark resembles a question being asked in the phrase “can someone help me with this problem?” you can also look at the word “can” this can be portraying a question being asked in the future.
I will show you how to do first one but it is simple addition and subtraction.
7y + 5 + (3 - y)
We just combine like terms
7y - y + 5 + 3
6y + 8
I will do the second one for subtraction
5 + 5q - (3q - 9)
since the subtracroon sign is outsiDr patenthesis you have to apply it to both terms
5 + 5q - 3q + 9
since it was -9 it became --9 which is +9
so:
5q - 3q + 5 + 9
2q + 14
The decimal 23.04001 does not have the value as the other three decimals
Step-by-step explanation:
7x² + 42x − 49
Factor using the AC method.
(x − 1) (7x + 49)
Set each factor to 0 to find the zeros.
x − 1 = 0, 7x + 49 = 0
x = 1, x = -7
These represent the x-intercepts of the graph y = 7x² + 42x − 49.
