Answer:
y = 7, x = 7
Step-by-step explanation:
11y + 13 = 90
11y = (90 - 13)
11y = 77
y = 7
2x + 6 = 20 (because 20 is half of 40)
2x = (20 - 6)
2x = 14
x=7
Two numbers that add up to 2 and multiply to -35
-5 and 7
Rewrite the expression using the above;
<u>(x - 5)(x + 7)</u>
Sn = a(r^n - 1)/(r - 1)
S4 = 228(4.8^4 - 1)/(4.8 - 1) = 228(530.8416 - 1)/3.8 = 228(529.8416)/3.8 = 120,803.8848 / 3.8 = 31,790.496
Answer: The answer is 183.08
Step-by-step explanation: see the picture attached
The answer should be (x, y) —> (x - 8, y + 10)
