Answer:
B
Step-by-step explanation:
Area of a triangle is 1/2 * Base * height
So we can say: 1/2 * k * (k-2)
That is equal to 24. Let's solve for k first:
Putting 8 into k, solves the equation, hence k is 8.
<em>So point P (8, 8- 2) , which is </em>
<em>P(8,6)</em>
<em />
The slope of OP is the change in y divided by change in x. Looking at the diagram, going from (0,0) to (8,6), the change in y is 6 and change in x is 8
So slope is 6/8
Reduced, that is 3/4
Answer choice B is right.
Answer:
Step-by-step explanation:
Given that,
y = x + 6 equation 1
3x - 3y = -18. Equation 2
Substitute equation 1 into equation 2
3x-3(x+6) = -18
3x - 3x - 18 = -18
-18 = -18
Therefore, it has no solution. Check attachment for echelon matrix solution
B. y = -2x + 5 equation 1
2x + y = -7. Equation 2
Substitute equation 1 into 2
2x -2x + 5 = -7
5 = -7
Since the equation is not balance, then, it has infinite numbers of solution.
C. y = -4x + 11. Equation 1
6x + y = 11. Equation 2
Substitute equation 1 into 2
6x - 4x + 11 = 11
2x = 11 - 11
2x = 0
x = 0
Also, y = -4x + 11
y = 0 + 11 = 11
Then, this has a unique solution I.e. one solution.
