Answer:
B
Step-by-step explanation:
The equations are:
2x + y - 7 = 0
and
1/3x + y -4 = 0
Let's rearrange the first to get:
y = -2x + 7
Putting this into the 2nd equation we get:

Now, y would be:

Solving the equation we see that there is 1 unique solution with 1 x value and another y values. That means, when graphing, the lines would intersect.
Answer choice B is right.
<u>Note:</u> Coincident means the same line and parallel means there would be no solution when solving
Answer:
4) 2(x - 3)^2 + 2(y + 5)^2 = 96.
Step-by-step explanation:
2x^2 – 12x + 2y^2 + 20y – 28 = 0
2(x^2 – 6) + 2(y^2 + 10y) = 28
2 ( (x - 3)^2 - 9)) + 2((y + 5)^2 - 25) = 28
2(x - 3)^2 - 18 + 2(y + 5)^2 - 50 = 28
2(x - 3)^2 + 2(y + 5)^2 = 28 + 18 + 50
2(x - 3)^2 + 2(y + 5)^2 = 96
Answer:
Cosine F = (40 / 41)
Step-by-step explanation:
Since it's a right angle triangle, we can use
SOHCAHTOA method.
Where CAH = cosine F = adjacent / hypotenus.
Opposite (FH) = 9
Adjacent (HG) = 40
Hypothenus(FG) = 41
Cosine F = adjacent / hypothenus
Cosine F = 40 / 41
Cosine F = 0.9756
F = cos⁻(0.9756)
F = 12.68°
See attached document for better illustration on the triangle.
