Ok so for part A, the x-coordinate of the intersection is the solution to <span><span>2<span>−x</span></span>=<span>4<span>x+3.
Part B </span></span></span><span>y>3x+10</span> for (8,10)
<span><span><span>10>3(8)+10</span><span>10>34
I am not sure about the thrid one
</span></span></span>
Answer:
460 m
Step-by-step explanation:
Boundary = perimeter
Perimeter = 2(length + width)
= 2(150 + 80)
= 2(230)
= 460 m

Answer:
D. x = 15; y = 5√3
Step-by-step explanation:
You don't need to know any trig to select the correct answer. You only need to know that the lengths of both sides must be less than the length of the hypotenuse. It is also helpful to know that √3 is about 1.732, so 10√3 ≈ 17.32.
Since x < 10√3, only answer choices A and D are viable.
Since y < 10√3, only answer choice D is viable.
_____
If you want to solve this using trig relations, you can recall that the sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. This means short side y is half the length of the hypotenuse 10√3, so y = 5√3. It also means longer side x is √3 times y, so is x = (5√3)√3 = 5·3 = 15.
x = 15; y = 5√3
It would be 2,5, and 6. The mode means the number that is repeating the most. Since 2, 5, and 6 all appear 3 times, that is the mode
