Im going to assume you know the formula.
sooo.
x= -11 +- √ (11)² -4 (1) (-15)
---------------------------------
2(1)
= -11 +- √121- (-60)
-------------------------
2
= -11 +- √181
-----------------
2
= -11 +- 13.45
-----------------
2
Either: Or:
X = -11 - 13.45
x = -11 + 13.45 ---------------
2
----- ----------
2
x = 1.23 x= -12.23

9 tenths - 3 tenths = 6 tenths. this is true the same way that 9 minus 3 = 6. In reality the tenths make both numbers decimals, but in this case the "tenths" is just a classification of the number and it doesn't effect the answer.
Answer:
29/14
Step-by-step explanation:
Start by working out the LCM of these (or any common denominator). A common denominator for 4 and 7 is 28 cuz 4 x 7 = 28.
3/4 = 21/28
4/7 = 16/28
3/4 = 21/28
(21+16+21)/28 = 58/28 which can simplify to 29/14
Answer:
y= 5.99(g) + 6.49(u)
Step-by-step explanation:
1) First you determine the variable in the equation $5.99, $6.49, g, and u.
2) Then analyze the equation and identify that each gold baseball trophy (g) is worth $5.99, and each uniform baseball trophy (u) is worth $6.49 each.
3) Since you are finding the total you insert a plus sign.
