Answer:
Answer B
Step-by-step explanation:
1. (1, -4) is NOT a solution because (1) - 2(-4) < 4 is false.
2. (-8, 2): -8 - 2(2) < 4 is true, and in simplified form is -12 < 4 (true) We must check whether this point (-8, 2) ALSO satisfies y > -2x - 5:
2 > -2(-8) - 5. Yes, this is true, so the given point satisfies both inequalities in Answer B.
Answer:
d. 19/13
Step-by-step explanation:
tan is the opposite over the adjacent (toa)
the opposite is 19 and the adjacent is 13
19/13
The answers have square roots among the choices so we probably shouldn't use that calculator button.
We can't just apply the area of the trapezoid formula

where b is the bottom base, t the parallel top, and h the height, because we don't know the top t.
It will be 10 less the leg of that right triangle, which we calculate as

Now we can apply the trapezoid formula. We have


Choice b
Answer:
y=-5*x+5
Step-by-step explanation:
the critical point are (5,0) and (0,1). the equation of the system is y=a*x+b. you substite y as 5 and 0 and x as 0 and 1 and you get it
