Well he replace 1 of 3 then he has 3 and if he replaced a total of all three then he would have 3 I'm not all that sure tho sorry this question is kinda confusing
Answer:
y = -2x + 6 and y = 1/3x - 7
Step-by-step explanation:
For A, using rise over run, you can count 2 units up and 1 unit left of any given point to get to the next point. Because left is the negative direction on a graph, the 1 unit is negative. To calculate slope, divide the rise (2) over the run (-1) and substitute the slope as m into y = mx + b. In the formula, b is the y-intercept (where the line crosses the x axis). The y-intercept of A is 6, so replace b in the formula with 6:
y = -2x + 6
The slope of B is 1/3 and the y intercept is -7, so substitute those values into the formula again to get the answer for B:
y = 1/3x - 7
I guess positive bcuz - -=+
<span>hypothesis :-
if x=30, then 3/4x+5≠20
let Q:- x=30 P:- 3/4x+5≠20
we need to prove if Q then P (Q →P)
proof :-
lets assume 34x+5=20 is true
now x=30
so
3/4(30)+5=27.5 ≠20
which is a contradiction
proved ^</span>
