The answer is y = 2x + 3.
x - Kay's age
y - Jane's age
m - Mary's age
<span>Jane is 3 years older than Mary: y = m + 3
</span><span>Mary is twice as old as Kay: m = 2x
</span><span>
y = m + 3
m = 2x
Substitute m in the first equation:
y = 2x + 3
</span>
Its kind of blurry
can u fix it
Answer:
Step-by-step explanation:
Plug in x = 2
g(2) = 3(2)² - 2*2 + 5
= 3* 4 - 4 + 5
= 12 - 4 + 5
= 8 + 5
= 13
Step-by-step explanation:
2400/100=24
24×10.5=252
252×5= 1260
Answer:
r = -1 or r = 5/3
Step-by-step explanation:
(2k - 1)/(k + 1) = (3k + 1)/(2k - 1)
(2k - 1)^2 = (k + 1)(3k + 1)
4k^2 - 4k + 1 = 3k^2 + 4k + 1
k^2 - 8k = 0
k(k - 8) = 0
k = 0 or k = 8
For k = 0,
(2k - 1)/(k + 1) = -1/1 = 1
For k = 8,
(2k - 1)/(k + 1) = 15/9 = 5/3
