Your answer would be “a”.
In order to receive a positive solution in the following equation, you must include a double negative to have them cancel each other out and come up with a positive value. Sorry if this is confusing it’s easier to explain this process in person rather than online but I hope this helps anyways :)
4x + y = 7
y = -4x + 7
using y = mx + b
b being your y intercept, (0,7)
35 is 5% of the number 175.
Newtons are used to measure force, so there is a measure of 4 newtons remaining.
To factor, we always have to look for common factors in the numbers given to us. In this case, in 1/2 and 6, the common factor is 1/2. Therefore, we will have to factor like so:
1/2d + 6 = 1/2 (d + 3)
Hope this helps!
