Answer:
a = 7, b = 24 if quadrant 1
a = -7, b = -24 if quadrant 2
Step-by-step explanation:
Tan theta = sin(theta) × sec(theta)
a/24 = (7/25) × (25/b)
ab = 168
a = 168/b
1 + tan²(theta) = sec²(theta)
1 + a²/576 = 625/b²
1 + 168²/576b² = 625/b²
1 = 576/b²
b = 24 (+ or -)
a = 168/24 = 7 (+ or -)
-5x + 2 > -38
-5x > -40
x < 8
-5x + 2 < -8
-5x < -10
x > 2
so the inequality becomes
2 < x < 8
so the graph will be a straight line with open circles on 2 and 8 and shading in between these values.
Answer:
y< -3/2x-2
Step-by-step explanation:
if you look at the graph, you can see the line is dotted, which means it is not equal to. eliminate a and c. the shade is toward the bottom of the y, which then you could eliminate a because b says the y value is greater than, which isn't true. you could also check it by plugging in any value for x!
