Q= 0 and R=14
I think you did it backwards lol but issok i answered
12 = x² - x
12 - 12 = x² - x - 12
0 = x² - x - 12
x² - x - 12 = 0
x = <u>-(-1) +/- √((-1)² - 4(1)(-12))</u>
2(1)
x = <u>1 +/- √(1 + 48)</u>
2
x = <u>1 +/- √(49)
</u> 2
x = <u>1 +/- 7</u>
2
x = 0.5 +/- 3.5
x = 0.5 + 3.5 x = 0.5 - 3.5
x = 4 x = -3

Answer:
Step-by-step explanation:
recall law of Sines :) the same as before Sin(A) /a = Sin(B) / b
[ when you see it a lot.. you'll remember it :D ]
for this problem Z =A=123 and a = 30
Y=B and b =14
Sin(123) / 30 = Sin(B) / 14
14 * 0.0279556 = Sin(B)
0.391379 = Sin(B)
arcSin(0.391379 ) = arcSin ( Sin (B) )
23.040 = B
Y = 23.0°
are you seeing how to do these? so you could on a test?
Answer:
27,648
Step-by-step explanation:
subtract 28,648 - 1,000
Answer:
- here is the equation : y= 3x+10
- table: o miles would be $10, 5 miles would be $25, 10 miles would be $40.
Step-by-step explanation:
for the second part you can use the equation above and substitute the value of x in the equation to find y.
explanation: 3 dollars per mile so 5 miles costs 15 dollars but since there is a flat fee of 10 dollars it would total to 25 dollars.
