Answer:
Step-by-step explanation:
-3
perpendicular slope is the negative of the reciprocal
the reciprocal of 1/3 is 3
the opposite of 3 = -3
For this problem we are asked to convert the volume of the medicine from liters to ounces. We need to have a conversion factor to answer this. The conversion factor would be 1L is equal to 33.814 ounces. We calculate as follows:
<span>570 mL ( 1 L / 1000 mL ) (33.814 oz / 1 L ) = 19.27 oz</span>
Answer:
d) 2x^2 + 2x -59
Step-by-step explanation:
(x-8)(x+4) + (x-3)(x+9) *multiply each term (...)(...)*
x^2 - 4x - 32 + x^2 + 6x -27 *combine like terms*
2x^2 +2x - 59
Answer:
A
Step-by-step explanation:
The answer is A because 4×15=60 and 60÷10=6
15×2=30 and 30÷5=6 so they are equal.
x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
