Answer:
f = -2.75
steps:-
2(f - 2) = 3 (2f + 5) 8
2f - 4 = 6f + 15 - 8
2f - 6f = 15 - 8 + 4
-4f = 15 - 8 + 4
-4f = 11
f = 11 ÷ ( - 4)
f = -2.75
Step-by-step explanation:
-3x + 6y = 18
-3x = 6y+14
a) the slope of the 1st equation = -(-3)/6 = ½
b) the slope of the 1st equation = -3/6 = -½
c) they are niether parallel nor perpendicular
Both A and B would be correct to use. You can use an example of your own to check it yourself. For example I did 10 emails all together and kept trying with the equations.
Answer:
Fig A
Step-by-step explanation:
in fig A, we can see that the subset that represents "trees", lies inside the subset that "has leaves". Hence in figure A, we can say that "All trees have leaves" or "if it is a tree, it has leaves"
in fig B however, we see that "has leaves" is inside of "trees", this means that the area in-between "has leaves" and "tree" represents the subset that there are trees without leaves. This is in contradiction to the statement "if it is a tree, it has leaves", hence this is not the answer.
X-intercept can be found when y=0
y-intercept can be found when x=0
Plug in x=0 to find the y-intercept
-3(0) + 4y = -12
4y = -12
y = -3
Plug in y=0 to find the x-intercept
-3x + 4(0) = -12
-3x = -12
x = 4
The x-intercept is (4,0)
The y-intercept is (0, -3)
