Answer:
b2=2A-b1
Step-by-step explanation:
picture is attached of what I did
hope it helps
1/5 equals 12 so 12 times 5 is 60 so
a=36
b=24
Your welcome
Answer:
x = 2010
Step-by-step explanation:
It is difficult separating and organizing the data. The best I can see is that the question is asking what is the value of x to make f(x) = t(x) true. x = 2010 is a year in which enrollment was the same, 740, in both f and t.
Answer:
It's linear!
Step-by-step explanation:
Just rewrite the equation as
y = x + 3
It has a slope and y-intercept, the most crucial parts that satisfy a linear equation. Since the slope is constant, it has to be linear.
tadah!
2(x - 5)² + 13 = 31
2(x - 5)(x - 5) + 13 = 21
2(x(x - 5) - 5(x - 5)) + 13 = 21
2(x(x) - x(5) - 5(x) + 5(5)) + 13 = 21
2(x² - 5x - 5x + 25) + 13 = 21
2(x² - 10x + 25) + 13 = 21
2(x²) - 2(10x) + 2(25) + 13 = 21
2x² - 20x + 50 + 13 = 21
2x² - 20x + 63 = 21
<u> - 21 - 21</u>
2x² - 20x + 42 = 0
2(x²) - 2(20x) + 2(21) = 0
<u>2(x² - 20x + 21)</u> = <u>0</u>
2 2
x² - 20x + 21 = 0
x = <u>-(-20) +/- √((-20)² - 4(1)(21))</u>
2(1)
x = <u>20 +/- √(400 - 84)</u>
2
x = <u>20 +/- √(316)
</u> 2
x = <u>20 +/- 2√(79)</u>
2
x = 10 <u>+</u> √(79)
x = 10 + √(79) U x = 10 - √(79)
