Answer:
B) f(x) = x if x ≤ -2
2 if x > -2
Step-by-step explanation:
B) f(x) = x if x ≤ -2 (The x and y coordinate have the same value)
2 if x > -2
I'll take this challenge since I'm not feeling lazy for once.... x would represent Gavin and y would represent Seiji.
a.
b. I will solve your system using substitution.
<span>Step 1: Solve </span>

for x

(add -y for both sides)

<span>Step 2: substitute </span>

for x in


<span>
</span>


(simplify both sides of the equation)

(add -425 to both sides)<span>
</span>


y=200
step 3: substitute 200 for y in





c. Already answered with the picture that is attached.
d. Gavin earned 225 dollars while Seiji earned 200 dollars.
Answer:
5. x = 17
7. x = 2
Step-by-step explanation:
The applicable relation is, "the product of the near distance to the circle and the far distance to the circle is the same for each secant." Distance is measured from the point where the secants intersect.

Using the rule, we have ...
7(7+x) = 8(8+13)
7+x = 24 . . . . . . . . . divide by 7
x = 17 . . . . . . . . . . subtract 7

<h3>7.</h3>
The same rule applies.
7(7 +6x -1) = 9(9 +x +3)
42x +42 = 9x +108 . . . . . . simplify
33x = 66 . . . . . . . . . . . . . subtract 9x+42
x = 2 . . . . . . . . . . . . . . divide by 33
