Assuming it's the same base log on either side you can just set the inside equal.

-2a + 9 = 7 - 4a
-2a + 4a = 7 - 9
2a = -2
a = -1

Indicate in standard form the equation of the line passing through the given point and having the given slope.
Svetradugi [14.3K]
Equation of a line passing through point (x1, y1) with slope m is given by y - y1 = m(x - x1)
y - 2 = -1/2(x - 6)
2(y - 2) = -(x - 6)
2y - 4 = -x + 6
x + 2y = 6 + 4
x + 2y = 10

35+25 > 10 ✔️
25 + 10 = 35❌
A cannot make a triangle.

10 + 5 = 15 ❌
B cannot make a triangle.

C.
35 + 45 > 55 ✔️
45 + 55 > 35 ✔️
35 + 55 > 45 ✔️
C can make a triangle.

D.
25 + 25 < 75 ❌
D cannot make a triangle.

Therefore, the answer should be C.
