TanX = SinX/CosX
TanX = 7/25 ÷ 24/25
Tanx = 7/25 * 25/24
TanX = 7/24...
-6x-4y=26
3x+4y=1
-3x=27
x=-9
3(-9)+2y=-13
-27+2y=-13
2y=14
y=7
(-9,7)~ Final Answer
Answer:
first one is b, second one is c
Step-by-step explanation:
3-4x<=11
-4x<=11-3
-4x<=8/:(-4)
x>=-2
The graph of this function would be a positive quadratic graph, so a curve with ends that go upwards, with a turning point at the top of the curve at (1, 2).
If we complete the square of this function, we get (x - 1)² + 2, which tells us that the turning point is (1, 2) as to make the bracket equal 0, x has to be 1, and 2 is the only number outside of the bracket.
I hope this helps!
