I want to say A because 3 and 5 have 15 and 6:15 is sounds like a ratio and D is just 4/10
Answer:
6 < x < 30
Step-by-step explanation:
By the Hinge Theorem, we know that
Angle BAC > Angle DAC
The two triangles that make the diamond have two equal sides. The third side of the upper triangle is longer than the third side if the lower triangle. To fit in the longer side, line AB had to be pushed outwards, forming a larger angle.
When we compare the two angles 48 and (2x-12), we now know that 48 is larger.
48 > 2x-12
48+12 > 2x
60 > 2x
60/2 > x
x < 30
Furthermore, angle DAC can't be negative or zero
2x - 12 > 0
2x > 12
x > 6
Answer:
y = -8
Step-by-step explanation:
Instead of trying to find the slope of the line through these two points in the usual rise/run fashion, note that y does not change as we progress from x= -5 to x= +8. This tells us immediately that this line is a horizontal one: y = -8.
