You are given the X value, replace x with 2 in the first equation to solve for y:
y=2x +3
y = 2(2) +3
y = 4+3
y = 7
Now replace y with 7 and x iwth 2 in the second equation and solve for k:
y = -x +k
7 = -2 +k
Add 2 to both sides:
9 = k
so k = 9
The point is given as k-2, which is 9-2 = 7, which is what y equals in the first equation.
K = 9

Answer:
12 weeks
Step-by-step explanation:
Josiah and kiri are each saving money josiah starts with 100$ in savings accound and adds 5$ per week . Kiri with 40$ in her savings account adds 10$ each week after how weeks Josiah and kiri will have the same amount of money in their savings account
Josiah:
100 + 5w
Kiri:
40 + 10w
Where,
w = number of weeks
After how weeks Josiah and kiri will have the same amount of money in their savings account
Equate the savings of the both of them
100 + 5w = 40 + 10w
100 - 40 = 10w - 5w
60 = 5w
w = 60/5
= 12
w = 12 weeks
Josiah and kiri will have the same amount of money in their savings account after 12 weeks
Label the 2 angles, one is x and the other is 8x.
90 = 8x + x
90 = 9x
10 =x
10 times 8 = 80. this is 8x.
10(which is x) + 80 (which is the 8x) = 90.
