7. Obtuse
8. Acute
9. No, because it’s the hypotenuse
10. Yes, because that part is not the hypotenuse and it is less than the greatest angle
Answer:
x = -2 + 2 i or x = -2 - 2 i
Step-by-step explanation:
Solve for x:
x^2 + 4 x + 8 = 0
Subtract 8 from both sides:
x^2 + 4 x = -8
Add 4 to both sides:
x^2 + 4 x + 4 = -4
Write the left hand side as a square:
(x + 2)^2 = -4
Take the square root of both sides:
x + 2 = 2 i or x + 2 = -2 i
Subtract 2 from both sides:
x = -2 + 2 i or x + 2 = -2 i
Subtract 2 from both sides:
Answer: x = -2 + 2 i or x = -2 - 2 i
<span>Use the slope intercept form y=<span><span>mx</span>+b, </span></span><span>where </span><span>m</span><span> is the slope and </span><span>b</span><span> is the y-intercept. So with saying that plug your problem in so y = -3x+3 so your answer would be m=-3 which is the slope.
~Hope this Helps! Good Luck!~

Answer:
(since there is no percentage given i will provide two alternate answers one including percentage and one exclusive of percentage)
cost of TV inclusive of tax = $500
we first multiply the tax with total amount
$500 * 5.5
= $500 * 55/10
=$500 * 11/2
= $250 * 11
=$2750
original price of TV = $2750
alternate answer assuming there is a percentage sign with 5.5
the amount of tax on TV is 5.5%
we first multiply the percentage of tax with total amount
$500 * 5.5/100
=$27.5
original price of TV = $500 - $27.5
= $472.5

Answer:
3.7 + r < 1.2
Step-by-step explanation:
a number r added to 3.7 is 3.7 + r
New expression 3.7 + r should be less than 1.2 --->
3.7 + r < 1.2
