Assuming we're working with the base 10 log, you can solve by making both sides exponents to a base of 10 (which cancels the log on the right side):
Answer:
KL = √10
Step-by-step explanation:
The product of KM and LN is twice the area, so is 12. This gives a quadratic in one or the other of those variables:
KM(8 -KM) = 12 . . . . the product of diagonals is twice the area
KM² -8·KM +12 = 0 . . . . rearrange to standard form
(KM -2)(KM -6) = 0 . . . . factor
KM = 2 or 6 . . . . values that make the factors zero
LN = 6 or 2 . . . . corresponding values of LN
The Pythagorean theorem tells you the side length from the diagonals:
KL² = (KM/2)² +(LN/2)² = 1² +3² = 10
KL = √10 . . . . . take the square root
The y-intercept is the point where the graph crosses the y-axis.
The line crosses the y-axis at
So, the y-intercept is
Answer:
subtraction= Mike is selling 50 apples. Kenny is selling 30 apples,"how many more" apples does mike have than ken?
50- 30 = 20
mike has 20 "more" apples than ken.
there are 15 kindergarteners, "but only" 10 chairs, "how many" chairs would the teachers have to "take away" from the room next door?
15- 10=5
k(x) = 6x - 12
k(x) = 18
substitute:
6x - 12 = 18 <em> |+12</em>
6x = 30 <em> |:6</em>
<h3>x = 5</h3>
